TL;DR: BlackRock has approved Ethena's USDe on its Aladdin platform, opening the synthetic dollar to institutional investors. The deal adds a $100 million liquidity facility for BlackRock's tokenized Treasury fund BUIDL and lets clients swap in and out of stablecoins around the clock.
BlackRock has approved Ethena's USDe as a cryptocurrency on Aladdin, its enterprise investment and portfolio management platform, putting the synthetic dollar in front of the institutional investors who run risk through that system. The two firms announced the deepened collaboration on Monday.
Aladdin is the engine BlackRock's institutional clients use to track, analyze, and manage risk across their portfolios. Adding USDe to it signals that a synthetic dollar can sit alongside the assets those desks already trade.
A $100 million liquidity facility for BUIDL
As part of the agreement, Ethena will support a $100 million liquidity facility through Securitize, the tokenization platform and transfer agent for BlackRock's USD Institutional Digital Liquidity Fund, known as BUIDL. The setup will let eligible BUIDL clients exchange their tokens for USDC, USDtb, and other supported stablecoins.
Clients can also convert those stablecoins back into BUIDL outside normal market hours. That round-the-clock movement is the point: it ties a tokenized Treasury fund to dollar-pegged tokens without waiting for traditional settlement windows.
Unlike fiat-backed coins such as Circle's USDC and Tether's USDT, USDe is a synthetic dollar that can generate more yield.
Building on an existing partnership
The two companies are not starting from scratch. BlackRock and Ethena already collaborate around USDtb, the Ethena stablecoin issued by Anchorage Digital Bank and backed primarily by BUIDL.
Launched in 2024 on Ethereum, BUIDL ranks among the world's largest tokenized U.S. Treasury funds. Tokenized Treasurys make up nearly half of the real-world-asset market, with about $15 billion onchain. The BUIDL fund itself holds roughly $3 billion in total value locked, according to DeFi Llama data.
