BlackRock and Ethena Labs have deepened their partnership through a new initiative that will provide institutional investors on BlackRock’s Aladdin platform with expanded access to Ethena’s products and enhanced liquidity for the BUIDL tokenized Treasury fund, according to a Monday statement.

The agreement includes a $100 million liquidity facility provided by Ethena through Securitize, enabling eligible BUIDL holders to seamlessly convert BUIDL into USDC, USDtb and other supported stablecoins, with the ability to reverse those transactions outside regular market hours.

The companies said the collaboration is intended to expand digital dollar infrastructure and support the wider institutional use of tokenized real-world assets. BlackRock said the facility enhances the utility of tokenized Treasury funds, while Ethena said it simplifies institutional access to onchain financial markets.

The partnership extends the firms’ prior collaboration involving USDtb, Ethena’s stablecoin backed primarily by BUIDL. BUIDL debuted in 2024 and has grown to roughly $3 billion in total value locked according to DefiLlama, making it one of the largest tokenized US Treasury funds.
