BlackRock's Aladdin Just Let a Synthetic Dollar Into the $20T Club 🏦

Ethena has integrated its synthetic dollar USDe into BlackRock's Aladdin investment platform, opening the token to the more than $20 trillion in assets that financial institutions manage through the system, the protocol said in an X post. Ethena framed the move as "unique institutional access," positioning USDe as natively visible to portfolio and risk teams already running on Aladdin. BlackRock has not published a matching statement.

USDe is one of the larger dollar-pegged tokens, with a supply near $4.5 billion as of June 29, and holds its peg through a delta-neutral strategy that pairs staked Ether ($ETH) with short perpetual futures. Native Aladdin support would let institutions track and analyze USDe inside tools they already operate, though Ethena has not detailed how deep the integration goes. BlackRock does not publish a single Aladdin asset figure, leaving the >$20 trillion figure to the company's own claim.

The deal also names BlackRock's BUIDL fund as the primary asset backing Ethena's whitelabel product, letting other firms issue branded versions of Ethena's dollars. BUIDL, the BlackRock USD Institutional Digital Liquidity Fund, launched in March 2024 and ranks among BlackRock's largest tokenized funds. It already supplies most of the reserves behind USDtb, the stablecoin backed by BUIDL that Ethena launched in late 2024. A new liquidity facility will connect BUIDL with USDe and USDtb for on-chain transactions, building on earlier work with Securitize that enabled around-the-clock swaps between the fund and Ethena's tokens.

Ethena's ENA token jumped on the announcement, rising almost 10% in the immediate aftermath to roughly $0.0811. The bounce cut against a steep slide, with ENA down about 17% over the prior week and roughly 70% over the year, and echoed an earlier lift that followed a Wall Street asset manager's investment in the protocol. USDe still carries regulatory exposure: in April 2025, Germany's BaFin ordered Ethena's local entity to wind down USDe issuance in what was the regulator's first action under the EU's MiCA rules. Whether Aladdin institutions ultimately allocate to USDe rather than simply monitor it is the test that will play out in the coming weeks.
