BlackRock has announced an expanded partnership with Ethena Labs, integrating Ethena's USDe stablecoin into its Aladdin platform. This collaboration includes a $100 million liquidity facility via Securitize to support BlackRock's BUIDL fund. The initiative enables qualified BUIDL clients to redeem their holdings for stablecoins like USDC and USDtb outside of exchange hours, facilitating seamless swaps back to BUIDL. This move enhances the interoperability between on-chain U.S. Treasury funds and stablecoins. Unlike traditional stablecoins backed by fiat, USDe is a synthetic dollar offering potentially higher yields. Currently, the BUIDL fund manages approximately $3 billion in locked assets.
