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.

Morpho (MORPHO): Leading Efficient, Permissionless Crypto Lending

Blockchain

Double-spending is a potential major risk in blockchain, but what is it and how can it be stopped? All is revealed here.

Cryptocurrencies exist thanks to the wonders of blockchain technology. They are a form of digital currency, with encryption techniques in place to manage and create monetary units and transfer funds.

In this digitalized world of cryptocurrency, you may have come across a term known as double-spending. 

Essentially, double-spending is the concept that someone can replicate Bitcoin or cryptocurrency transactions with funds being sent to two different addresses simultaneously.

So, why is double-spending such a problem? And how can it be prevented in a blockchain?

Let’s begin by refreshing our minds on the concept of blockchain.

 is a decentralized ledger that stores transactions. It guarantees mutual trust and a collective consensus among all partners involved.

The revolution brought about by blockchain in the cyber world has created a safe and robust means of storing, managing, processing, and recording information and digital transactions, often highly sensitive.

What makes blockchain innovative is that a single computer, or node, does not finalize processes; many computers are simultaneously involved.

Cryptocurrencies such as Bitcoin are among blockchain’s many diverse applications. Digital identities, contracts, logistics and an increasing amount of entities can benefit from using blockchain.

With regard to digital currency, guaranteeing that a particular unit cannot be duplicated is extremely important. This is because digital information can be relatively easily reproduced by tech-savvy individuals familiar with the blockchain network, and computing commands required to tamper with it.

As we’ve already established, double-spending is essentially where the same funds are sent to two recipients simultaneously. 

It occurs when a blockchain network is disturbed, and the cryptocurrency is basically stolen. The person responsible would then send a copy of the transaction to make it look genuine, or even delete the transaction altogether to make it look like it had never occurred.

Without proper countermeasures to resolve such an issue, the entire transaction will be rendered fundamentally destabilized and undermined. Users have no protocol to verify whether the funds they have received aren’t also being spent elsewhere.

Hence, for a digital currency to function reliably, there have to be strict mechanisms preventing this kind of behavior.

Double-spending destroys and compromises the technological basis of a blockchain. Its whole concept is the opposite of what the blockchain is all about. Hence, the possibility of double-spending would ultimately undermine the trust in a cryptocurrency such as Bitcoin or any other blockchain-based digital currency.

In this analogy, when all generals lead a coordinated attack with their armies, they will achieve victory. However, as soon as a general defects or attacks another general, the entire battle, similar to a blockchain, will be compromised and eventually lost.

Now that we’ve understood the basis of double-spending, let’s look at three popular ways scammers

 network occurs when a sole individual or organization controls most of the

, causing potential network disruption. When this happens, the so-called “attacker” attains enough mining power to omit or alter the sequence in which transactions are conducted purposely.

During a 51% attack, the attacker could reverse transactions made by them during this time, leading to a double-spending problem. Moreover, the attacker can also inhibit some or all transactions from confirmation (i.e., a transaction denial of service) and prevent some or all other miners from mining, something known as “mining monopoly.”

Bitcoin Gold, a cryptocurrency that came about as a fork of Bitcoin, was a victim of such attacks in 2018 and 2020.

A race attack involves sending two opposing transactions simultaneously with similar funds; however, only one transaction is confirmed.

During such an attack, the main idea is to invalidate other payments by validating only that transaction that benefits the attacker, i.e., funds sent to an address that they can control.

Also, race attacks need recipients who accept unconfirmed transactions as a form of payment.

Unlike a race attack, a Finney attack involves the attacker pre-mining a single transaction into a block; however, it is not broadcast immediately to the entire network.

In this kind of double-spending attack, the attacker spends the same coins in a different transaction and then broadcasts the previously mined block, thus invalidating the payment.

These attacks need to occur in a distinct sequence. Like race attacks, they also depend on the recipient accepting unconfirmed transactions.

There are two ways to prevent double-spending.

Moreover, blockchain technology prevents double-spending via peer-to-peer file-sharing technology, coupled with public-key cryptography. Along with these setups, ownership structures of cryptocurrencies are logged in the blockchain, which is fundamentally a public ledger, while simultaneously being confirmed via cryptographic protocols and by the overall cryptocurrency community.

Hence, since all transactions are openly chronicled and cryptographically secured simultaneously on thousands of nodes worldwide, everyone involved can see them and verify those that have already been made. 

When it comes to Bitcoin, all transactions are verified by miners. This ensures that the transactions performed during the verification process are irreversible and cannot be altered computationally, hence successfully resolving double-spending. 

How Likely Are Double-Spending Attacks to Occur?

Even though it has occurred, thankfully double-spending in a blockchain is difficult to achieve.

This is because once a cryptocurrency’s blockchain becomes large enough, as with the case of Bitcoin or Ethereum, the probability of a single individual or group gaining enough computing power to overthrow all other participants speedily becomes very low.

Moreover, modifying all previously confirmed blocks becomes more problematic as the chain grows, since the blocks are all linked via cryptographic proofs. As a result, the more confirmations in a block, the higher the cost of altering or reversing transactions.

Hence, a successful double-spend attack would perhaps only modify a few recent blocks’ transactions, and only for a relatively short time.

As for Bitcoin, its consensus algorithm, also known as Proof of Work (PoW), ensures that miners can only validate a new block of transactions given all network nodes mutually agree that the block hash given by the miner is correct. The block hash verifies that the miner has put in enough effort, found an effective solution for the block’s problem, and will therefore reward some Bitcoins for solving it. 

With double-spending, participants can scam electronic cash systems for financial benefit, using the same funds two or more times. 

Initially, there were no suitable solutions for resolving this problem. It posed a considerable challenge for the growth and progress of cryptocurrency and Bitcoin. Fortunately, the practice of blind signatures, as well as certain stringent and transparent protocols, have provided an innovative solution for such decentralized financial schemes. 

In addition, the formation of PoW mechanisms and blockchain technology has turned Bitcoin into a powerful and decentralized digital currency system, considerably reducing the possibility of fraud and double-spending.
