BlackRock Adds Ethena USDe to Aladdin, BUIDL Backing & $100M Liquidity Facility
BLK•BlackRock has integrated Ethena’s USDe stablecoin into its Aladdin risk management platform, giving institutional clients direct access to USDe tracking alongside other assets. The firm also designates its BUIDL tokenized Treasury fund as the primary reserve for Ethena’s white-label stablecoins and provides a $100 million liquidity facility.
1. USDe Integration into Aladdin
BlackRock has added Ethena’s USDe stablecoin to its Aladdin platform, which serves major asset managers, banks, insurers and pension funds. Institutions can now track, analyze and manage USDe alongside equities, bonds and other assets using familiar Aladdin portfolio and risk tools.
2. BUIDL as Primary Reserve Asset
BlackRock’s BUIDL tokenized Treasury fund is now the main reserve asset for Ethena’s stablecoin services, including white-label solutions for corporate issuers. BUIDL holds tokenized exposure to short-term Treasuries, cash and repurchase agreements to underpin stablecoin collateralization.
3. $100 Million Liquidity Facility
Ethena is committing a $100 million liquidity facility through Securitize, enabling eligible BUIDL holders to swap between BUIDL and supported stablecoins such as USDC and USDtb outside normal market hours. This mechanism enhances on-chain flexibility and round-the-clock access to digital collateral.
