How to Become a Bybit VIP: Your Guide to Exclusive Benefits

LETSTOP is a drive-to-earn mobile app that monitors phone distractions while driving. Learn more about how it works in this article.

Smartphone distractions have created an unprecedented road safety crisis worldwide. 

: texting behind the wheel makes drivers six times more likely to crash than drunk driving does — yet millions of drivers still use their phones while operating vehicles.

This article explores how LETSTOP is transforming safe driving into rewarding experiences through blockchain technology. We'll examine its drive-to-earn model, reward system, tokenomics and potential as both a road safety solution and an investment opportunity.

 is a drive-to-earn mobile app that monitors phone distractions while driving. Users earn STOP tokens for phone-free driving through a gamified system that transforms daily drives into rewarding experiences.

A life-changing car accident caused by a distracted driver running a red light inspired LETSTOP co-founder Almog Nissan to reimagine road safety. Together with co-founder and CEO Dor Levy, they envisioned rewarding safe driving, rather than just punishing dangerous behavior.

The founders built a platform that combines automotive technology, cryptocurrency and AI to revolutionize road safety through rewards. This innovative approach has quickly gained traction, with over 50,000 users logging over 3 million kilometers of safe driving since the app’s launch.

Distracted driving claims thousands of lives annually, with 

, of which 9% are directly linked to phone use. LETSTOP aims to tackle this crisis as follows:

Each of these objectives works harmoniously to support LETSTOP's ultimate mission of transforming road safety into a rewarding experience that benefits both individual drivers and society.

The LETSTOP app operates through a sophisticated system that monitors and rewards safe driving through the following apps and features:

The result is a dynamic system in which better driving habits unlock greater earning potential.

The following five core features power LETSTOP's drive-to-earn ecosystem.

LETSTOP uses a dynamic 40-level system to make safe driving rewarding. As drivers earn XP through distraction-free journeys, they advance from Level 1's 2% bonus toward Level 40's 70% boost. Through this gamified approach, daily commutes become opportunities to climb the ranks while building safer driving habits.

LETSTOP Credits are the core currency of the platform, earned directly through safe driving achievements. Earning rates directly scale with user level, vehicle type and subscription tier as follows: PRO subscribers enjoy unlimited earning potential, while PLUS and LITE tiers are capped at 300 and 150 monthly credits, respectively.

In the STOP Store, users invest their earned credits into virtual cars with unique earning multipliers. From the basic model's 2% bonus to the Jazzster GN's 150% boost, each vehicle offers different strategic advantages for maximizing rewards.

Beyond vehicles, the store features mystery boxes containing rewards from 10 to 450 credits, as well as car upgrades and subscription boosts. Users can also access a voucher marketplace to redeem credits for real-world rewards through LETSTOP's partnership network.

LETSTOP's triple-boost system combines vehicle multipliers for immediate earnings acceleration, a level-progression system for sustained growth and a 5% referral program for community expansion. Premium membership unlocks enhanced benefits across three tiers, while special events create time-limited opportunities for increased rewards.

The platform's comprehensive rewards system operates across three membership tiers, each one tailored to different user needs. LETSTOP PRO (at $9.90 monthly) offers unlimited credit earning potential and exclusive benefits. The PLUS tier provides a balanced option at $4.90 monthly with a 300-credit earning cap, while the free LITE tier allows users to earn up to 150 monthly credits.

Beyond direct earnings, the rewards system incorporates partner vouchers, cryptocurrency conversion options and community features, such as leaderboards. Achievement rewards recognize milestones in users' safe driving journeys, while the upcoming cryptocurrency integration will allow users to convert their efforts into tradeable STOP tokens.

LETSTOP has shown consistent progress, with the following key milestones already achieved:

Looking ahead to 2025, LETSTOP plans to implement the following key developments:

These developments aim to strengthen LETSTOP's position as a leader in drive-to-earn while furthering its mission to enable safer roads worldwide.

STOP is an SPL token built on the Solana network. It’s designed to bridge safe driving behavior with cryptocurrency rewards. The STOP token implements an annual halving mechanism to ensure long-term value preservation, similar to Bitcoin's model, but accelerated to align with the project's growth trajectory.

STOP has a max supply of 100 million tokens, to be distributed in the following manner:

The growing adoption of LETSTOP's drive-to-earn app and its impact on road safety directly influence STOP's price trajectory. While cryptocurrency forecasts remain speculative by nature, multiple price analysis platforms project the following for STOP:

These forecasts suggest a positive long-term outlook for STOP, driven by the growing drive-to-earn sector and LETSTOP's innovative approach to road safety. However, STOP's future value will ultimately depend upon user adoption, platform development and broader market conditions.

Morpho (MORPHO) is an efficient Ethereum-based protocol revolutionizing decentralized lending with customizable peer-to-peer and pool-based solutions.

Liquidity pools have revolutionized decentralized lending and borrowing by offering a wide choice of product options and significant liquidity levels. For several years, protocols like 

 (COMP) have been lauded as true innovators that introduced a real game-changer: pool-based lending and borrowing. However, a closer look reveals that things aren’t as efficient and smooth as they may seem within the world of crypto lending. The problem is that lending pools on decentralized protocols often have mismatches between lenders and borrowers, with the former substantially outnumbering the latter. As a result, lenders earn only meager 

s, while borrowers pay exorbitant fees to access funds via these pools. Another critical problem is the lack of customizability in lending and borrowing products, with many protocols adopting a one-size-fits-all approach.

Morpho (MORPHO) is a decentralized protocol on 

 (ETH) that aims to improve the efficiency and flexibility of crypto lending and borrowing by offering a unique model that combines the elements of 

 (P2P) and pool-based matching of lenders and borrowers. To be precise, one of Morpho's essential products, Morpho Optimizers, specifically focuses on P2P matching, with pool-based lending and borrowing used as a fallback option. Morpho also offers users an excellent level of customization for creating new lending markets through its core protocol.

With its innovative lender-borrower matching mechanism and highly customizable and flexible markets, Morpho greatly improves capital allocation and transaction efficiency in the 

 (MORPHO) is an Ethereum-based decentralized lending protocol that offers a unique P2P order matching mechanism to improve the efficiency and affordability of 

 The platform also enables users to create efficient lending markets with highly customizable lending and borrowing parameters. Additionally, it offers a product, Morpho Vaults, for curated lending at varying risk levels.

, a France-based software development company founded in 2021 by Merlin Egalité and Paul Frambot. It's also supported by the nonprofit 

As its first major product, the project launched Morpho Optimizers on the Ethereum blockchain in 2022. Morpho Optimizers is designed as an add-on solution for lending pools on Aave and Compound to help match individual lenders and borrowers. The transacting parties can benefit from a more efficient lending process than with the default pool-based mode.

In January 2024, the project launched Morpho Blue, later rebranded to Morpho, a solution to help users create highly flexible lending markets with custom parameters and options. Morpho acts as the backbone of the Morpho ecosystem, and the project team has turned its focus to promoting and further developing this product. At the same time, Morpho Optimizers remains an integral part of the platform's core offering, albeit in a less prioritized state than Morpho.

The Morpho protocol consists of three main products — Morpho, Morpho Vaults (based on the underlying protocol) and the legacy Morpho Optimizers. Morpho allows users to create individual lending markets by specifying their preferred options for the following key attributes:

All these parameters are highly customizable, with minimal interference from the Morpho governance mechanism. Some parameters do have to conform to certain requirements; e.g., the IRM and LLTV must be from the list approved by the protocol's governance.

Morpho's high level of customizability is a significant departure from the typical model used on decentralized lending and borrowing platforms. On most other protocols, there are fixed parameters governing the lending and borrowing process; e.g., only certain collateral assets, lending assets or LLTV rates are allowed. In contrast, Morpho lets you customize all of these options, giving lending market creators an unmatched degree of freedom. The protocol offers the following key benefits to users, developers and market operators:

While Morpho is currently the platform's flagship product, the legacy Morpho Optimizers continues as a key offering in the platform's product line. Morpho Optimizers are add-on layers to the Aave and Compound lending pools. They can be used to facilitate a peer-to-peer match between lenders and borrowers. Since typical lending pools — including on platforms like Aave and Compound — are often heavily skewed with more lenders than borrowers, both parties end up paying excessive fees. Borrowers have to confront high costs due to the need to service the many lenders in the pool. In turn, lenders fight for the meager scraps left over from insufficient numbers of borrowers.

By using a P2P matching mechanism, Morpho Optimizers effectively takes the lender and borrower away from pool-based interaction and establishes a direct relationship between them. This allows users to borrow assets at cheaper rates, while also delivering better APYs for lenders. If either party withdraws from the direct lending relationship, both parties have the option to use the standard lending pools on Aave and Compound as a fallback.

The platform's third core product, Morpho Vaults (covered in more detail below) utilizes the underlying protocol and provides a way to lend through carefully curated market options at different risk profiles. This can suit lenders who are less proficient in using fully customized markets, but still prefer to take advantage of the lending opportunities offered by Morpho.

In order to create a custom lending market on Morpho, you need to have some technical proficiency and, preferably, knowledge of Solidity, the programming language that the protocol uses for its smart contracts. As noted earlier, developers can create a custom market by supplying five base parameters — a collateral asset, an asset offered for lending, an oracle, a preferred IRM and an LLTV. The first four of these normally require an Ethereum smart contract address to be specified. For the collateral and lending assets, these are the addresses for the tokens' contracts. The selected oracle is also usually established via a pointer to its smart contract address, although oracle-less hard-coded prices for the collateral and lent assets are acceptable. Morpho also maintains Ethereum addresses for each IRM whitelisted by the protocol's governance; developers can use these when choosing a preferred IRM.

The last value, LLTV, is a hard-coded figure that defines the threshold beyond which a loan becomes unhealthy due to its poor 

. Liquidators on Morpho are protocol actors who are incentivized to cover bad debts in return for collateral, similar to the method used on many other lending platforms. They’re allowed to liquidate up to 100% of the debt. In return, liquidators receive the debt's collateral, as well as an additional incentive for their work.

Since Morpho is an oracle-agnostic protocol without a built-in oracle, each market can have its own oracle that sources prices for the collateral and lending assets from external sources. Developers are completely free in that regard, and can even hard-code asset prices for the market if they don't wish to use a price oracle at all. Naturally, an oracle is preferred for maintaining the most up-to-date and dynamic pricing information.

The IRM used is the only base parameter with which developers are somewhat restricted in their choice, as only whitelisted IRMs are allowed for a market. As of mid-November 2024, there’s just one whitelisted IRM that market creators can specify — the 

. This model dynamically adjusts interest rates to maintain the proportion of borrowed funds to supplied funds at close to 90%.

Morpho Vaults are a tokenized vault product that offers curated lending opportunities with varying pre-programmed risk parameters. Each vault is associated with a single loan asset, and can allocate deposits across multiple Morpho markets, thereby leveraging the overall liquidity available on the Morpho protocol. Morpho Vaults suit lenders who prefer predictable risk management over the uncertainty of completely custom markets. Each lender can earn APY rates commensurate with their chosen 

There is no limit on the number of vaults you can open on Morpho. Thus, you might even allocate funds to different vaults with significantly different risk levels to diversify your exposure.

Morpho Vaults' curated nature eliminates the need for users to spend time researching and evaluating individual markets' risk levels and return opportunities, as risk exposure is actively managed by the vault.

Since the vaults are connected to the underlying protocol, and source liquidity from it, they’re dynamically rebalanced, which helps optimize yields. Thanks to their permissionless and immutable nature, the vaults are also completely transparent. Moreover, they’re noncustodial, granting users full control over their deposited assets, which can be withdrawn at any time.

A lender deposits an asset into a Morpho Vault and receives shares of the vault as confirmation of their investment. The vaults themselves are tokenized products utilizing Ethereum's 

 standard, designed to represent tokenized vaults for yield-bearing assets. Each vault may be owned by a 

 (DAO), an individual DeFi expert or some algorithm maintained by a DeFi platform. A vault can be owned by only one entity. The owner may specify additional roles/entities for managing the vault. These roles can include one curator, one guardian and multiple allocators.

The curator is a party who sets certain limits, rules and boundaries for the vault, such as specifying asset supply limitations and enabling/disabling specific markets. Curators are instrumental in maintaining appropriate risk levels for their vaults. Assets that lenders lock in a vault are supplied to the protocol's underlying markets, based on curators' whitelists. There can only be one curator for each vault.

The role of guardian is a key vault position. A guardian protects the integrity and security of the vault. Guardians can revoke any action by the vault owner (or other entities) if they consider it to be against the interests of vault lenders. Each vault can only have one guardian, typically a DAO consisting of vault depositors.

Allocators are protocol actors whose job is to rebalance the liquidity utilized by Morpho Vaults to optimize interest rates and accessible liquidity. An allocator’s job is to rebalance and optimize the total liquidity, either manually or using bots, to best meet the needs of Morpho borrowers.

Morpho Vaults' operations aren't regulated by the protocol's governance mechanism. Each vault owner is responsible for their vault's governance model. Specific roles, such as the curator and the guardian, are designed to help in establishing transparent and secure governance procedures for a vault.

What Is the Morpho Crypto Token (MORPHO)?

The platform's native cryptocurrency, MORPHO, is envisioned as a 

. Holders of MORPHO have the right to participate in decision-making on the platform's future direction, general rules, deployment of smart contracts and allocation of funds from the treasury. Although Morpho promotes lending and borrowing markets that operate with minimal interference from the protocol's governance community, there are some general guidelines and rules through which the community needs to establish certain standards, minimum requirements or whitelists. MORPHO token holders are instrumental in this process.

The original MORHPO token was launched on Ethereum in June 2022 with a supply cap of 1 billion. However, there were limitations to the original token contract that negatively affected its functionality. Specifically, the token wasn't designed to facilitate efficient on-chain voting. As a result of these limitations, the project decided to relaunch the token, now on an upgraded contract. The new reincarnation of MORPHO will offer better functional capabilities, including more efficient on-chain governance processes. 

As of the time of writing on Nov 17, 2024, the project team has yet to deploy the new token. The new MORPHO will also be a supply-capped crypto, with a maximum and total supply of 1 billion. The token's supply distribution shares are shown in the chart below.

 token before its market launch. Bybit Pre-Market Trading is an over-the-counter (OTC) trading platform that provides access to promising new cryptocurrencies before their listings on the Spot market. The key advantage of the platform is the ability to access cryptocurrencies at desirable rates before the broader crypto market affects their prices.

Bybit's carefully designed curation process ensures that only crypto assets with solid potential and fundamentals are whitelisted for Pre-Market Trading. This saves you the time required to investigate each cryptocurrency, and reduces the risk of investing in scam projects. Naturally, you’re also encouraged to 

 on crypto assets you might consider purchasing through Bybit Pre-Market Trading.

Morpho represents a unique and potentially highly effective approach to DeFi lending and borrowing. The platform's facilitation of isolated and highly customizable lending markets gives DeFi users unmatched freedom in terms of choice and variety. In addition, users who prefer the stability of curated and well-defined risk profiles can take advantage of Morpho Vaults for more predictable yields. The use of the overall underlying protocol liquidity along with entities such as allocators makes Morpho Vaults particularly effective at optimizing lending and borrowing costs.

While custom lending markets launched via the protocol are now Morpho's key focus, the legacy Morpho Optimizers also continue to offer value. P2P matching of lenders and borrowers as an add-on to the standard pool-based mechanism is a functionality many DeFi users will find helpful. Morpho Optimizers can offer lenders and borrowers active on Aave and Compound an alternative and highly effective way of conducting their operations.

With this arsenal of innovative and unique products, the Morpho protocol is quickly shaping up as a leading platform in the lending niche of the DeFi industry.

The CAT20 token standard leverages Bitcoin's security and UTXO model to build advanced Bitcoin-based fungible tokens with high composability and smart contract-like functionality,

 (ETH) blockchain appeared on the horizon in 2015 with its 

 (DApps), many in the blockchain industry assumed that 

 (BTC) would eventually fade into obscurity. The world's oldest blockchain simply didn't have any of the novel features that its younger rival boasted. Fast-forward to nearly a decade later, and several innovative protocols and token standards have ushered in the era of a totally new Bitcoin, one featuring its own NFTs, fungible tokens and even smart contract–like functionality.

 protocol has enabled Bitcoin-based NFTs. The BRC-20 token standard, based on the same ordinal inscription theory, then introduced the ability to create fungible tokens on the chain. Soon afterward, the 

 protocol opened up a way to create fungible assets much more lightweight than 

 tokens. With all of these innovations, it seems that Bitcoin has finally found its groove in the new blockchain world.

In September 2024, another potentially paradigm-changing token standard, CAT20, was proposed for the Bitcoin network. CAT20 allows developers to create Bitcoin-based fungible tokens that adhere to both the blockchain's native standards and the 

 (UTXO) model, while introducing high composability levels, creating opportunities for complex smart contract–like functionality.

 is a new proposed fungible token standard for the Bitcoin blockchain (

The standard was proposed in September 2024 by the CAT Protocol team, and is applicable to any blockchain that supports the OP_CAT opcode. Opcodes are special scripts that instruct blockchain transactions to perform certain operations. The Bitcoin blockchain supported the OP_CAT opcode until 2010, when the platform's anonymous founder, 

, removed it due to security and transaction efficiency concerns.

Currently, there's a revived interest in OP_CAT within the Bitcoin user community, and several parties have proposed its reintroduction. If OP_CAT is re-enabled on Bitcoin, CAT20 will likely move from a proposed state to a fully implemented standard on the chain. Among the blockchain networks that currently support it is Fractal Bitcoin (FB), a 

 sidechain solution that supports higher speeds and scalability levels for Bitcoin transactions.

The recently proposed CAT20 standard is not to be confused with the much earlier (and unrelated) CAT20 standard for compliant security tokens and tokenized securities, 

To understand CAT20 tokens, it's crucial to be aware of what the OP_CAT opcode does. Originally available on Bitcoin, it lets developers con

enate (hence the name) two pieces of data together, potentially opening a way to create complex transaction functionality. However, OP_CAT also has a certain potential to be exploited for running denial-of-service (DOS) attacks and congesting the Bitcoin network.

Due to these vulnerabilities, Satoshi Nakamoto disabled OP_CAT, along with several other opcodes. OP_CAT, which the CAT20 standard heavily relies on, still isn’t functional on Bitcoin as of early October 2024. The primary rationale behind Nakamoto's decision probably lay in the desire at the time to keep Bitcoin strictly an environment for secure asset transfers and storage.

However, in the past few years, the blockchain has moved beyond its original state, with protocols and standards like BRC-20, Runes and Ordinals Inscriptions ushering in an era of a higher degree of network activity. Additionally, a variety of Bitcoin-linked Layer 2 solutions have contributed to the chain's ecosystem development. 

With all of these technologies now fully operational on the Bitcoin network, many of its community members have questioned the need to keep OP_CAT disabled.

At the end of the day, if BRC-20 tokens are allowed to proliferate on the chain, and various Layer 2 protocols have introduced smart contract-like functionality for it, why would an exception be made for OP_CAT? Voices clamoring to re-enable OP_CAT are growing louder by the day, and there's an expectation that the opcode may be switched back on. 

If and when that happens, CAT20 can support the creation and use of Bitcoin tokens with a significant degree of composability. Significantly, this could open up opportunities to leverage a variety of DApps within the Bitcoin ecosystem.

How Does the CAT20 Standard Affect the Bitcoin Blockchain?

Because CAT20 tokens are highly composable and modular, they could significantly increase the sophistication of Bitcoin transactions, potentially paving the way for full-fledged DApp functionality directly on the network.

At the same time, the ability to provide sophisticated functionality may lead to congestion on the network, due to the amount and complexity of operations these tokens are capable of producing. Bitcoin already struggles with the new standards and protocols — BRC-20, Runes and Ordinals Inscriptions — that have led to a large spike in activity on its network. The introduction of CAT20 tokens on the blockchain could further increase traffic levels.

CAT20 tokens adhere to Bitcoin's underlying security mechanism, which is based on the 

 (PoW) mining procedure. It’s been instrumental in establishing the blockchain's reputation as a highly secure transactional environment. By leveraging PoW, CAT20 tokens would ensure that their operations are protected to the same level as native BTC assets.

Besides PoW, another element that ensures Bitcoin's security is its well-regarded UTXO transaction model, whereby Bitcoin balances and transfers are represented by outputs from earlier transactions. CAT20 tokens are based on UTXO and directly leverage Bitcoin's own script at 

. This means that these tokens don't need to rely on off-chain indexers — software used to organize transactions and simplify the querying of the blockchain.

The CAT20 standard creates opportunities for cross-chain operations, as it can be implemented on any network that supports the OP_CAT opcode. We noted above that the Fractal Bitcoin Layer 2 sidechain is an example of a network with OP_CAT support. Besides Fractal Bitcoin, there are two notable Bitcoin forks with OP_CAT functionality enabled — 

CAT20 tokens have built-in functionality to support simplified payment verification (SPV). This technology allows lightweight clients such as mobile phones to verify the authenticity of CAT20 tokens in a decentralized and efficient way.

Although CAT20 holds certain potential for cross-chain interoperability, the existing network of chains that support OP_CAT (and which could thus theoretically support CAT20) is quite limited. The Fractal Bitcoin project is a new Layer 2 solution, still in the early stages of its market presence, while Bitcoin Cash and Bitcoin SV are minor players in the world of smart contract–capable chains. These two platforms both support some degree of smart functionality using their own unique mechanisms. 

Still, their DApp capabilities are far behind those of Ethereum and other smart contract chains, such as 

 (SOL). As such, the token standard's potential reach is relatively restricted, especially since OP_CAT is still not operational on Bitcoin itself.

CAT20's ability to support complex, composable functionality can potentially lead to network congestion, due to both the large amount of processing required and the general increase in demand for DApps. Bitcoin already struggles with the issue of congestion, and the introduction of CAT20 might exacerbate this problem. 

The chart below shows the number of Bitcoin transactions over the past three years (to Oct 6, 2024). It’s impossible to miss the gradual rise in network activity over the previous year or so:

The CAT20 standard is still in the early stages of its development. It’s been newly introduced and promoted by the CAT Protocol, and many practical details of its implementation have yet to be defined or made public.

The rise in on-chain activity and DApp usage that CAT20 could spur would likely affect not only network congestion levels, but also transaction costs. Bitcoin is already facing increases in these costs, due to the flurry of activity related to BRC-20 tokens, Runes tokens and Ordinals Inscriptions NFTs. With the arrival of CAT20, the costs of transacting on Bitcoin may rise further.

CAT20 has a number of advantages over the BRC-20 fungible token standard. First, unlike BRC-20, CAT20 requires no off-chain indexers. With all of its operations conducted strictly on-chain, CAT20 tokens enjoy both higher efficiency and a better security profile than BRC-20 assets do. Additionally, CAT20 technology allows for far more flexible and sophisticated functionality than what the BRC-20 token standard can provide.

CAT20 tokens share certain similarities with Runes, another highly popular fungible token variety on Bitcoin. Both tokens largely leverage the on-chain environment for their functionality, although Runes does require indexers while CAT20 doesn’t. Both standards can be lightweight, though in the case of CAT20 it largely depends upon the actual token design and intended functionality. In addition, both Runes and CAT20 tokens leverage Bitcoin's UTXO model.

However, the critical difference between these two token technologies is that CAT20 tokens can be used to enable fairly sophisticated DApps, ranging from 

 protocols. In contrast, the Runes protocol has mostly been confined to supporting 

ARC-20 is a standard designed for fungible tokens that supports digital ownership management and asset representation for collectibles and NFTs. While ARC-20 is a fungible token standard, its main focus is on digital representation for distinct items and NFTs. In contrast, CAT20 is designed for fungible tokens with diverse applications and use cases. 

While both token standards could potentially have use cases in 

 (DeFi) or other DApp niches, CAT20 assets are capable of supporting more sophisticated and programmable functionalities.

As of the time of this writing Oct 8, 2024), the future of the CAT20 standard is highly dependent upon whether and when the OP_CAT opcode is re-enabled on Bitcoin. This will be determined by the overall Bitcoin community via online discussions and proposal deliberations. Unlike some chains with highly structured on-chain governance processes, Bitcoin has a flexible, mostly off-chain and less structured process of making decisions on matters as important as the reintroduction of critical opcodes.

CAT20 was proposed in September 2024 and active discussions are ongoing. It might take the Bitcoin community a few weeks or months to decide on this issue. Of course, there's always the possibility that OP_CAT’s proposed reintroduction could either be rejected or left in limbo for an extended period.

The CAT20 standard is a significant step forward for Bitcoin, due to CAT20’s potential for relatively sophisticated programmability, reliance on Bitcoin's underlying security mechanism, UTXO-based nature and cross-chain interoperability. However, concerns about network congestion and rising transaction fees are running high within the Bitcoin community right now, primarily due to the avalanche of activity related to BRC-20, Runes and Ordinals Inscriptions. 

Nevertheless, there's hope that the Bitcoin community is capable of distinguishing between technologies that are mostly suitable for meme coin acrobatics, and those that can provide useful DApp-like functionality. At the very least, the team at CAT Protocol hope so — and will be keeping their fingers crossed. If OP_CAT is re-enabled, expect CAT20 tokens to become a new hit on the world's largest blockchain network.
