Securitize and Ethena launch 24/7 BUIDL liquidity facility

What happened

Securitize and Ethena Labs have launched a round-the-clock liquidity facility for BlackRock's USD Institutional Digital Liquidity Fund, known as BUIDL. Securitize operates the service and Ethena backs it. The facility opened with $50 million and can make another $50 million available within about an hour, according to announcements reported by Unchained and Crypto.news.

At launch, the pool holds $25 million in USDC and $25 million in BUIDL. Eligible investors can exchange BUIDL for supported stablecoins, including USDC, and move those stablecoins back into BUIDL. The service is designed to work when banks and traditional markets are closed, including weekends.

Securitize CEO Carlos Domingo said the launch moves toward a system where institutional investors can obtain liquidity when they need it rather than only during traditional market hours. Ethena Labs founder Guy Young said digital assets trade around the clock and institutional liquidity needs to keep pace, according to statements shared in the announcement.

Access is restricted to eligible BUIDL holders and depends on the facility's terms, supported transaction periods and operational requirements. Crypto.news reported that around-the-clock availability does not guarantee every transaction will settle immediately or that the full $100 million capacity will always be available.

Why it matters

The facility addresses a practical gap for institutions that hold tokenized cash-like assets but operate in markets that do not stop for banking hours. A holder that needs dollar stablecoins on a weekend would otherwise wait for banking and settlement systems to reopen. The arrangement gives such investors a route to USDC without redeeming through traditional channels. Its initial size is small relative to BUIDL itself: Crypto.news cited RWA.xyz data showing the fund at about $1.66 billion, making the $100 million maximum capacity roughly 6% of the fund and the $25 million initial USDC inventory about 1.5%. That makes the launch a targeted liquidity tool rather than a wholesale redemption channel.

What the data shows

Securitize's published breakdown lists $25 million in USDC and $25 million in BUIDL at launch. The second $50 million tranche may become available within approximately an hour, subject to capacity and terms, bringing total capacity to $100 million. Crypto.news emphasized that the $100 million figure is total capacity, not $100 million in stablecoins held continuously for withdrawals. BUIDL gives investors exposure to cash, U.S. Treasuries and repurchase agreements through tokenized fund shares. The fund is listed for U.S. qualified purchasers, with onboarding that includes identity checks, subscription agreements and transfer-agent approval before an investor is whitelisted.

Background

The launch follows a facility first outlined in June, when Ethena and BlackRock widened their partnership. That deal also brought Ethena's synthetic dollar, USDe, onto BlackRock's Aladdin portfolio and risk system, Unchained reported. The companies already collaborate on BUIDL and USDtb, Ethena's digital dollar that is mostly backed by BUIDL. Crypto.news reported that earlier round-the-clock USDtb swaps, introduced in June 2025, let qualified users onboarded through Securitize exchange between BUIDL and USDtb using a liquidity fund smart contract. Ethena became a large BUIDL investor in March 2025, when a $200 million allocation helped push the fund above $1 billion in assets.

Securitize, listed on the New York Stock Exchange under the ticker SECZ, says it manages about $5 billion in assets as of September, Unchained reported. Other BUIDL liquidity arrangements predate the new facility. In February, Uniswap Labs and Securitize introduced trading through UniswapX, and in November 2025 Securitize said eligible Binance traders could use BUIDL as off-exchange collateral, according to Crypto.news.

What is still unclear

One open question is the stablecoin set. Unchained's June report said holders would be able to move into USDtb as well as USDC, while the Nov. 12 announcement named only USDC. It is also not yet known how often the second $50 million tranche will be drawn, which Unchained described as an early test of weekend demand.

What to watch

Market participants will watch whether the additional $50 million is used quickly and whether the facility remains available during periods of stress. The terms governing capacity, supported transaction periods and operational limits will shape how useful the service proves. BlackRock has separately explored broader uses for tokenized funds as collateral, including arrangements that let holdings move without first being redeemed for cash, Crypto.news reported.
