Our verdict on BlackRock BUIDL
7.8/10BlackRock BUIDL suits institutions and eligible investors who want exposure to short-term U.S. Treasuries with onchain settlement, daily dividends and use as exchange collateral. Its main strength is the combination of conservative reserves, a major asset manager and a recognized tokenization platform. The main caveat is access and transparency: onboarding goes through an investment team, and fees, minimums and eligibility rules are not published in the material reviewed. It is not a permissionless DeFi yield product.

What is BlackRock BUIDL?
BlackRock BUIDL, formally the BlackRock USD Institutional Digital Liquidity Fund, is a tokenized fund launched in 2024. It is described as BlackRock's first Securitize-powered tokenized fund, and DefiLlama lists it under real-world assets since July 2024.
The fund is backed by short-term U.S. Treasuries, repurchase agreements and cash. A May 2026 search snippet puts assets under management at roughly $2.3 billion, while another listing shows a higher figure of about $3.25 billion. The figures differ by source and date.
BUIDL has become a reference example of traditional finance meeting blockchain rails. It is accepted as collateral on Crypto.com and Deribit, and reports mention a second tokenized fund filed by BlackRock with the SEC. The fund has no governance token, and no audits are listed on DefiLlama.
How BlackRock BUIDL works
BUIDL is an investment fund managed by BlackRock. Its assets are short-term U.S. Treasuries, repurchase agreements and cash. Instead of shares recorded only in a traditional register, the fund's shares are issued as tokens through Securitize, a tokenization platform.
Investors who qualify buy fund tokens and receive dividends from the interest the underlying assets earn. Public reporting describes these as daily payouts, Monday to Friday. Tokens can be held in approved wallets and, in some cases, posted as collateral on venues such as Crypto.com and Deribit.
Because the fund is a regulated-style product, not an open DeFi protocol, a transfer agent and compliance checks govern who can hold the tokens. A third-party oracle service reports that it verifies the fund's backing onchain.

- Fees, minimum investment and eligibility rules are not published on the pages reviewed.
- DefiLlama lists no smart-contract audits for the product.

BlackRock BUIDL fees
Fees for BUIDL, such as management fees, onboarding costs or minimum investment sizes, are not published in the material reviewed. Prospective investors would see them in the fund's offering documents and from the Securitize investment team.
As with any onchain asset, network transaction fees may apply when moving tokens. The blockchains used are not stated, so those costs cannot be estimated here.
Is BlackRock BUIDL safe?
BUIDL is a fund product, not a permissionless DeFi protocol, so the main risks are different. Holders depend on BlackRock as manager, on Securitize as tokenization platform and transfer agent, and on the quality of the underlying Treasuries, repos and cash counterparties. DefiLlama lists no smart-contract audits, and the specific contract-level security work is not described in the material reviewed.
The fund's licence and regulatory terms are not detailed in the sources reviewed beyond reports of SEC filings for BlackRock's tokenized funds. Read the offering documents for redemption terms, eligibility, custody arrangements and legal protections. Check that investing in such a product is permitted where you live.
