BlackRock has achieved a landmark in institutional DeFi adoption through its sBUIDL token’s integration with Euler’s lending protocol on the Avalanche network. This marks the first direct DeFi protocol integration for BlackRock’s tokenized treasury product since its March 2024 launch, according to developer Securitize.
The integration enables institutional investors to use sBUIDL – a wrapped version of BlackRock’s BUIDL token representing shares in a U.S. Treasury fund – as collateral for decentralized lending on Euler. This development follows Avalanche’s May 2025 implementation of network upgrades specifically designed for institutional DeFi use cases.

BlackRock’s Strategic Blockchain Expansion
The world’s largest asset manager has progressively expanded BUIDL’s blockchain presence since its initial Ethereum launch:
| Blockchain | Integration Date | Key Feature |
|---|---|---|
| Ethereum | March 2024 | Initial launch |
| Avalanche | May 2025 | First DeFi integration |
| Polygon | November 2024 | EVM compatibility |
| Arbitrum | November 2024 | Layer 2 scaling |
Securitize’s Technical Architecture
As BlackRock’s tokenization partner, Securitize developed the cross-chain bridge enabling sBUIDL’s Avalanche deployment. The system maintains:
- Real-time balance synchronization across chains
- KYC/AML compliance layers
- Institutional-grade custody solutions
Avalanche’s Institutional Infrastructure
The network’s technical capabilities proved critical for securing the BlackRock partnership:
- Sub-second transaction finality
- Customizable compliance modules
- EVM compatibility with enterprise extensions
This integration follows JPMorgan’s 2024 Kinexsys FX settlement system deployment on Avalanche, which processed $12B in transactions during its first quarter.
Euler’s risk management framework – featuring tiered asset pools and dynamic loan-to-value ratios – reportedly satisfied BlackRock’s security requirements. The protocol now supports sBUIDL in its highest-rated collateral tier alongside USDC and wrapped BTC.
Market analysts note this development could accelerate institutional capital flows into DeFi. Since the announcement, Avalanche’s native token (AVAX) has seen increased trading volume across major exchanges.
Securitize CEO Carlos Domingo emphasized the strategic importance: “Our Avalanche integration creates new yield opportunities for BUIDL holders while maintaining the security standards institutional investors require.”
The partnership leverages Avalanche’s Evergreen subnet technology, which provides:
- Private transaction execution
- Regulatory-compliant address whitelisting
- Custom gas token options
Industry observers highlight the timing – coming just weeks after the SEC approved spot Ethereum ETFs – as evidence of growing regulatory clarity for institutional crypto products.

This integration signals a maturation phase for DeFi infrastructure, with traditional finance giants now actively participating in decentralized protocols. As BlackRock deepens its blockchain engagements, analysts predict increased competition among Layer 1 networks to attract institutional deployments through customized solutions.
