Securitize and Ethena switch on a $100M after-hours swap facility for BlackRock's BUIDL
Securitize and Ethena Labs turned on a $100 million round-the-clock facility letting eligible holders of BlackRock's BUIDL tokenized Treasury fund swap shares for stablecoins like USDC outside market hours.
Securitize and Ethena Labs have put live a $100 million liquidity facility that lets eligible investors in BlackRock's USD Institutional Digital Liquidity Fund (BUIDL) swap fund shares for supported stablecoins, including USDC, around the clock — including outside traditional market hours, The Block reported on November 12.
The mechanics, per The Block: the facility opens with $50 million in initial liquidity, split evenly between BUIDL and USDC, with a further $50 million replenishing within an hour as the first tranche is drawn down. The two firms first announced the $100 million facility in June. It extends an existing arrangement: Ethena's USDtb stablecoin is backed primarily by BUIDL, and in June 2025 the companies integrated to offer 24/7 atomic swaps between the tokenized fund and Ethena's dollar token.
The launch lands as BlackRock pushes BUIDL further on-chain. The Block notes that in February, BlackRock and Securitize tapped Uniswap to enable direct on-chain BUIDL trading via UniswapX, and pegged the fund's size at $2.4 billion at that time.
Key facts

- $50M at launch, split evenly BUIDL/USDC, with another $50M replenishing within an hour (The Block).
- First announced in June 2026; builds on a June 2025 atomic-swap integration (The Block).

- BUIDL ≈ $2.4B as of February, when UniswapX trading went live (The Block).
The real-world read
Treat the framing with care: the only voices here are the two companies selling the product. Securitize CEO Carlos Domingo and Ethena founder Guy Young are both quoted casting the facility as "infrastructure" that closes the gap between market hours and always-on blockchains — standard launch-day messaging from interested parties, not independent assessment.
A few things go unsaid. $100 million is modest against a $2.4 billion fund, and the structure — $50 million up front, the rest within an hour — means true instant depth is $50 million; the headline number assumes a one-hour refill the companies haven't shown under stress. "Eligible investors" is doing quiet work too: BUIDL remains a gated, qualified-investor product, so this is institutional plumbing, not open access. And there's a circularity worth flagging — Ethena's USDtb is backed largely by BUIDL, so a facility smoothing BUIDL-to-stablecoin swaps also props up Ethena's own collateral loop. Who provides the stablecoin liquidity, and on what terms, wasn't disclosed.
One date wrinkle: the facility was announced in June but goes live now, a roughly five-month gap neither firm explains.
Opinion, and whose
Domingo (Securitize) frames the facility as a step toward a financial system where institutions "access liquidity when they need it." Young (Ethena) calls it a move toward making tokenized assets "more useful for institutional participants." Both are the vendors; both statements are promotional, not verified outcomes.
