BlackRock Unlocks $30B in Assets: sBUIDL Leads a New Era of RWA Liquidity

In May 2025, the blockchain market witnessed a historic turning point: BlackRock's tokenized U.S. Treasury fund — BUIDL — valued at nearly $30 billion, was officially integrated into the DeFi world through a new vehicle called sBUIDL, made possible by a partnership between Securitize, Euler Protocol, and Avalanche Network. This event not only paves the way for traditional capital to flow into DeFi legally and efficiently, but could also become a landmark that reshapes how the entire global financial system operates.

BlackRock Unlocks $30B in Assets: sBUIDL Leads a New Era of RWA Liquidity

In May 2025, the blockchain market witnessed a historic turning point: BlackRock's tokenized U.S. Treasury fund — BUIDL — valued at nearly $30 billion, was officially integrated into the DeFi world through a new vehicle called sBUIDL, made possible by a partnership between Securitize, Euler Protocol, and Avalanche Network.

This event not only paves the way for traditional capital to flow into DeFi legally and efficiently, but could also become a landmark that reshapes how the entire global financial system operates.

BUIDL — A Giant With Locked Liquidity

Launched in 2023, BUIDL (BlackRock USD Institutional Digital Liquidity Fund) is the world's largest tokenized U.S. Treasury fund, issued as an ERC-20 token and custodied by Bank of New York Mellon. Despite its enormous potential, BUIDL could not be used in DeFi protocols due to SEC regulatory constraints. The result: $30 billion in assets sitting idle on-chain.

sBUIDL — Opening the Door for Traditional Capital to Enter DeFi

To break through this deadlock, BlackRock and Securitize launched sBUIDL — a wrapped version of BUIDL purpose-built for DeFi. Users can deposit BUIDL into the Securitize system and receive sBUIDL at a 1:1 ratio, ensuring full legal compliance and redeemability at any time.

sBUIDL conforms to the ERC-20 and ERC-4626 standards, enabling seamless integration into DeFi protocols while still satisfying KYC/AML requirements through Securitize's verification infrastructure.

Integration Into Euler on Avalanche — A Strategic Move

sBUIDL's DeFi debut took place on Euler Protocol, a modular lending platform running on Avalanche — a blockchain known for low fees, fast throughput, and cross-chain support via Wormhole.

Users can use sBUIDL as collateral to borrow USDC, USDT, and other stablecoins, with loan-to-value (LTV) ratios of up to 92.5%. Notably, borrowers earn yield from BUIDL while also receiving AVAX rewards through the liquidity mining program.

A Liquidity Explosion: From $30B to Trillions

In a short span, sBUIDL has already unlocked billions in liquidity. By the end of 2025, sBUIDL's utilization on Euler could exceed $5 billion — and by 2027, it could generate $900B–$1.5T in derivative liquidity if broadly deployed across platforms like Aave, Compound, and additional blockchains such as Ethereum and Solana.

According to BCG, the global tokenized asset market could reach $16 trillion by 2030 — with government bonds accounting for more than 50% of that figure. sBUIDL is emerging as the blueprint that institutions like Vanguard and JPMorgan are likely to follow.

Challenges That Remain

Despite its revolutionary potential, sBUIDL faces real risks:

  • Smart contract security: Euler was hacked in 2023, leaving the community cautious even though the protocol has since been upgraded.
  • Regulatory risk: sBUIDL remains in the SEC's crosshairs if it expands too quickly.
  • Market volatility: Yields from AVAX and DeFi may become unattractive in a bear market, putting liquidity at risk.
