 have become a cornerstone of the crypto ecosystem, providing stability in a market known for its volatility. Among recent innovations is USDtb, a new stablecoin from Ethena Labs that leverages BlackRock's tokenized funds to create a reliable digital dollar alternative. 

This article examines USDtb's unique structure, its relationship with Ethena's existing 

 stablecoin and the way it bridges traditional finance with decentralized systems to offer a differentiated risk profile for both retail and institutional users.

 is a blockchain-based USD stablecoin primarily backed by the BlackRock BUIDL tokenized treasury fund. It provides institutional-grade stability with 24/7 accessibility in volatile market conditions.

, USDtb follows a traditional fully-backed stablecoin model in which each token represents one US dollar. This structure ensures value stability and transparency through a direct 1:1 backing relationship.

Eighty percent of USDtb reserves are invested in the BlackRock USD Institutional Digital Liquidity Fund (BUIDL), which holds cash, repurchase agreements and US Treasury instruments. The remaining 2% is held in stablecoins like 

, in order to maintain immediate liquidity during weekends or holidays when traditional treasury markets are closed.

, is known for USDe, its innovative synthetic dollar. The Ethena protocol bridges traditional finance with decentralized systems through sophisticated financial engineering and institutional partnerships.

Generally based on Arthur Hayes's early 2023 "Dust on Crust" blog post, Ethena has quickly established itself as a major player in the stablecoin ecosystem. The protocol employs 

 that pair spot crypto assets with corresponding short positions on derivatives exchanges, enabling impressive revenue while maintaining stability.

The Ethena ecosystem is governed by its native ENA token. With the introduction of USDtb, Ethena expands its offerings to include a fully-backed stablecoin supported by BlackRock's institutional-grade BUIDL fund, thus diversifying its solutions to suit different market conditions and users.

BlackRock's USD Institutional Digital Liquidity Fund (BUIDL) is a tokenized money market fund that invests in dollar-equivalent assets, including cash, US Treasury bonds and repurchase agreements. Developed in partnership with Securitize, a leading 

 tokenization company, BUIDL represents BlackRock's entry into the tokenized treasury space.

BUIDL is cross-chain compatible, operating across multiple blockchains including Ethereum, 

. As the largest tokenized fund of its kind, BUIDL provides institutional-grade backing for USDtb, lending credibility to the stablecoin through BlackRock's established reputation in traditional finance.

USDtb represents Ethena's strategic approach to creating a more resilient ecosystem that can weather various market conditions, while bridging the gap between DeFi innovation and traditional financial systems. Following are some of its characteristics.

USDtb operates as a blockchain-based stablecoin through a sophisticated infrastructure designed for independence, transparency and security. Unlike traditional dollars, USDtb enables faster and cheaper transactions, while maintaining stability through institutional-grade backing.

The minting and redemption process occurs through a 

 system with strict controls. Only verified

 checks can mint or redeem USDtb directly. The system’s safeguards include maximum mint/redeem limits per block and whitelisted custodian addresses to prevent manipulation.

For transparency, USDtb maintains visible on-chain 

 and publishes monthly fund administrator NAV reports. Holders can use USDtb just as any digital dollar for payments, trading or storing value, though they receive no governance rights or claims to income generated by the backing assets.

USDtb offers the following four key benefits that make it a distinctive and valuable addition to the digital asset ecosystem.

USDtb delivers institutional-grade security through its strategic backing by BlackRock's BUIDL fund, which comprises over 80% of its reserves. This partnership leverages BlackRock's trillion-dollar asset management expertise, providing unparalleled stability and trust.

The USDtb stablecoin's sophisticated legal framework features a bankruptcy-remote structure, while its core smart contracts have successfully passed three comprehensive security audits by industry leaders Pashov Audit Group, Quantstamp and Cyfrin.

USDtb creates powerful bridges between traditional finance systems and cryptocurrency markets. For institutions, it serves as a low-friction entry point to digital assets without requiring users to navigate the complexities of volatile cryptocurrencies.

For individual users, USDtb is designed for seamless integration across DeFi protocols, use as collateral on 

 (CEXs) and prime broking venues, and direct accessibility for TradFi institutions — expanding its role within both digital and traditional financial ecosystems.

USDtb combines world-class expertise from multiple industry leaders. Ethena has demonstrated remarkable execution capability by scaling USDe to over $6 billion in market cap, while BlackRock brings unmatched credibility and treasury management expertise.

In addition, Securitize contributes cutting-edge tokenization technology as the recognized leader in converting real-world assets to blockchain tokens, creating a stablecoin with institutional pedigree, which is rarely seen in cryptocurrency markets.

Unlike TradFi systems that are constrained by business hours and settlement windows, USDtb operates continuously on blockchain infrastructure. This enables round-the-clock trading, transfers and redemptions, regardless of traditional market hours.

The strategic 20% stablecoin reserve ensures seamless redemptions, even during weekends or holidays — when treasury markets are closed — thus eliminating cross-border friction and enabling value transfers in minutes (rather than days).

USDtb's forward-looking strategy focuses on expanding its ecosystem presence and institutional adoption throughout 2025. The project aims to establish USDtb as a reliable dollar alternative, with multiple avenues for growth.

Looking toward broader financial applications, Ethena plans to incorporate USDtb into new DeFi offerings, including perpetual swap trading, prediction markets and undercollateralized lending solutions. These expanded use cases aim to increase USDtb utility beyond simple transfers.

USDtb operates as a fully collateralized stablecoin with a straightforward 1:1 peg to the US dollar. Each token is backed by institutional-grade assets, primarily BlackRock's BUIDL treasury fund (80%) and USDC reserves (20%), creating a stable digital dollar alternative.

The token supply expands and contracts, based on market demand, through a controlled minting and redemption process. New USDtb can only be created when onboarded users deposit equivalent value in approved assets, ensuring the backing never falls below 100%.

Distribution follows a hybrid model: initial minting is restricted to KYC-verified participants, but once in circulation, USDtb tokens trade freely across blockchain ecosystems with no transfer restrictions. This approach balances regulatory compliance with the open accessibility expected within 

USDtb is purely a transactional asset, with no governance functions. Holders receive no voting rights, participation in management decisions or claims to revenue generated by the backing assets — keeping the token's purpose clear as a stable medium of exchange and store of value.

Minting/Redeeming USDtb directly requires KYC and onboarding, in addition to following a structured verification process:

: Prospective users must first confirm they’re in a permitted jurisdiction by reviewing the 

: Qualified entities should make contact via this 

 to begin the evaluation process and determine suitability.

: All applicants must complete comprehensive know-your-customer and anti–money laundering verification. This process is thorough, and is designed to meet institutional compliance standards.

: Upon successful verification, users may be onboarded at their discretion, subject to the USDtb Terms and USDtb Mint User Agreement.

: Whitelisted users can then deposit approved assets into the system and receive newly minted USDtb through the secure smart contract infrastructure.

The direct minting process is primarily designed for qualified institutional participants who can meet the regulatory and compliance requirements.

While USDtb offers institutional-grade stability in the stablecoin market, investors should carefully weigh its strengths and risk factors before making investment decisions.

With its institutional backing and integration with Ethena's ecosystem, USDtb shows promise as a stable digital dollar alternative, particularly during market downturns. However, potential investors should 

 and consider their goals before investing, as USDtb is primarily a stability tool, rather than a yield-generating asset.

USDtb merges BlackRock's institutional credibility with blockchain technology's accessibility, creating a powerful bridge between traditional finance and decentralized systems. With its secure backing structure, utility during times of market volatility and an ambitious integration road map, USDtb is positioned to become a significant player in the digital dollar ecosystem.

USDtb: The Ethena stablecoin backed by BlackRock's digital funds

Stool Prisondente (JAILSTOOL) is a meme coin launched on Solana, which stems from an inside joke within Dave Portnoy's Barstool Sports community.

Meme coins thrive on hype, but few have the backing of an internet icon like Dave Portnoy. Stool Prisondente (JAILSTOOL), a Solana-based token, was born from a joke about Portnoy’s hypothetical imprisonment, and has since become a real, tradable asset. Its rise highlights the ongoing Solana meme coin frenzy — as speculation meets sheer internet absurdity.

But is JAILSTOOL just another flash-in-the-pan meme coin, or could Portnoy’s influence push it toward becoming something bigger? This article will cover everything you need to know, from its origins and market performance to the risks of trading a coin driven entirely by online sentiment.

The Solana meme coin scene is a high-stakes, high-reward battlefield, where new tokens rise and fall within days — sometimes hours. Recent months have been particularly wild:

Unlike many meme coins that pop up without real backing, JAILSTOOL’s so-called Portnoy effect sets it apart.

, a media empire built on sports, pop culture and internet controversy. Portnoy is a polarizing figure, known for his unfiltered takes, viral rants and ability to move markets through sheer personality — whether in stocks or crypto.

During the 2021 crypto bull run, Portnoy dabbled in Bitcoin (BTC), Dogecoin (DOGE) and other speculative assets, often live-streaming his trades to his millions of followers. Though his crypto track record is mixed, his ability to command attention is undeniable.

This influence has played a major role in JAILSTOOL’s rapid rise.

The origin of Stool Prisondente, a meme coin launched on Solana, stems from an inside joke within the Barstool Sports community. Its name references a hypothetical scenario in which Portnoy ends up in prison — a concept that his audience found amusing enough to turn into a cryptocurrency.

The token was minted shortly after Portnoy publicly expressed interest in getting reinvolved with meme coins. Seizing the moment, opportunistic traders launched JAILSTOOL — and, thanks to Portnoy’s implicit endorsement, it quickly gained traction.

Though Stool Prisondente has no fundamental utility, its value lies in community engagement and the ongoing meme-driven trading culture that has defined Solana’s recent market dynamics.

 a fully diluted valuation (FDV) of $9.35 million, with a 24-hour trading volume of $12.45 million. The token hit an all-time high (ATH) of $0.2179 on February 9, 2025, when it reached a peak FDV of over $209 million. However, it has since plunged by over 95%, highlighting the extreme volatility of meme coins, and is currently 17.3% above its ATL of $0.007417 on February 18, 2025. 

The coin has experienced wild price swings typical of meme-driven assets. Early traders saw huge gains, while latecomers have been caught in inevitable sell-offs. This volatility is a feature, not a bug, and is what makes meme coins both exciting and incredibly risky.

 have directly impacted JAILSTOOL’s price movements. His ability to drive engagement and trading volume is reminiscent of Elon Musk’s influence over Dogecoin.

Several of Portnoy’s recent tweets have kept the coin’s momentum alive, with traders hanging onto every word for potential buy or sell signals. However, Portnoy himself has been careful not to overcommit — and therefore, likely to avoid any regulatory scrutiny.

Still, the mere association with Portnoy has been enough to sustain interest, proving once again that in the meme coin market, narrative often outweighs fundamentals.

For all its hype, JAILSTOOL is a high-risk asset, and potential investors should proceed with caution. Here’s why:

In short, investing in JAILSTOOL is more like betting than traditional investing. If you’re in it, you’re speculating on the next viral moment, rather than long-term value.

Stool Prisondente (JAILSTOOL) is a prime example of the modern meme coin era — a joke that turns into a multimillion-dollar token through hype, community engagement and effective influencer backing. Its association with Dave Portnoy has given the meme coin a stronger foothold than most new ones.

For those looking to trade JAILSTOOL, it’s now available on Bybit, where users can access the

The year 2024 was a landmark year for the cryptocurrency industry, marked by significant events that reshaped the landscape of digital assets.

The year kicked off with a bang as the U.S. Securities and Exchange Commission (SEC) approved 

 in early 2024. This approval not only legitimized Bitcoin in the eyes of traditional investors, but also paved the way for massive institutional investment into the cryptocurrency market.

Market sentiment turned bullish in March, driven by the successful Bitcoin Spot ETF launch. Bitcoin's price surged and broke its 2021 all-time high (ATH) price of $69,000. This marked the first time Bitcoin made a new ATH before a Bitcoin halving event.

Bitcoin underwent the most recent and much-anticipated 

 in April 2024, which reduced the reward for mining new blocks, effectively halving the rate at which new BTC are generated.

Finally, in November 2024, Donald Trump was re-elected as president of the United States, which had a profound impact on the crypto market. His administration's pro-crypto stance included pledges to make the U.S. the "crypto capital of the world." This fueled optimism and drove Bitcoin’s price above the historical
