Is the BUIDL Token Safe? BlackRock's Tokenized Fund Explained
The BUIDL token scores 87/100 (Tier 2) on the RWTS Trust Score. See what BlackRock's tokenized fund holds, how redemption and custody work, and the verdict.
Verdict: The BUIDL token, BlackRock's USD Institutional Digital Liquidity Fund, scores 87/100 (Tier 2) on the RWTS Trust Score, placing it among the strongest-rated tokenized treasury products we cover. It is backed by short-term US Treasuries, cash and repurchase agreements, custodied at BNY Mellon, administered by BlackRock, and tokenized by Securitize. That combination of a top-tier asset manager, a regulated custodian and a compliant transfer agent is why the rating is high. It is not, however, a risk-free instrument, and access is limited to qualified investors. We rate. You decide.
The Trust Score, dimension by dimension
The RWTS Trust Score breaks a token into six dimensions: backing quality, reserve verification, redemption mechanics, audit rigor, regulatory posture and on-chain track record. Here is how the BUIDL token scores on each.

The standout dimensions for BUIDL are backing (22/25) and audit (15/15). The fund holds cash, US Treasury bills and repo, which are among the highest-quality reserve assets available, and it carries full third-party audit coverage. Regulatory posture (15/15) is also maximal, reflecting the fund's structure under a US exemption and the KYC-gated distribution through Securitize. On-chain track record (7) is the youngest dimension for tokenized funds generally and remains the main area where scores across the category are still maturing. You can read exactly how each dimension is weighted on our methodology page.

What is the BUIDL token?
BUIDL is the on-chain share token of BlackRock's USD Institutional Digital Liquidity Fund. Each token is designed to represent one dollar of the fund and to hold a stable value of $1.00, with the yield earned by the underlying portfolio paid out to holders as additional tokens. In practical terms, holding BUIDL is closer to owning a share of a money-market-style fund than holding a payment stablecoin, even though the token moves like one on-chain.
The fund invests in a portfolio of cash, US Treasury bills and repurchase agreements collateralized by Treasuries. BlackRock acts as the investment manager, BNY Mellon serves as custodian and administrator, and Securitize operates as the transfer agent and tokenization platform. That layered structure is deliberate: it separates asset management, custody and the on-chain registry so that no single party controls the whole stack.
How custody and redemption work
Custody of the underlying assets sits with BNY Mellon, a regulated bank custodian, rather than inside a smart contract. This is a key reason BUIDL scores well on backing and audit: the reserves are held and reported through traditional institutional rails, not self-attested balances.
Redemption runs through Securitize. Qualified holders burn tokens to receive USD, with settlement typically on the next business day. Because a next-day redemption window is less useful during nights and weekends, an additional smart-contract facility lets holders convert BUIDL into a stablecoin around the clock. That off-ramp improves real-world liquidity without changing what the fund holds. If you want a broader comparison of how redemption differs across products, our tokenized treasuries hub tracks each one.
Is the BUIDL token safe?
The honest answer is that BUIDL is high quality but not risk-free. At 87/100 (Tier 2) it clears our verification, audit and regulatory bars at a strong level, and the reserve mix is about as conservative as tokenized products get. The residual risks worth understanding are:
Access risk. BUIDL is gated to qualified purchasers with a minimum investment and mandatory whitelisting. It is not a retail-friendly wrapper.
Smart-contract and transfer-agent risk. The token layer and the stablecoin off-ramp introduce technical surfaces that a bare Treasury bill does not have.
Track-record maturity. Like most tokenized funds, its on-chain history is still short relative to legacy money-market funds, which is why that dimension carries fewer points for now.
None of these are red flags. They are the ordinary trade-offs of putting an institutional fund on a public ledger. For context on the category as a whole, see our explainer on what RWA crypto is.
Is BUIDL better than USYC?
Both are strong Tier 2 products. The BUIDL token scores 87/100 (Tier 2) and USYC scores 84/100 (Tier 2). The two share identical backing (22/25), verification (16) and regulatory (15) marks. The difference comes from audit: BUIDL carries 15/15 while USYC carries 12. In practice that means the two are close cousins, and the better fit depends on which chains you use, how the yield accrues and whether you can access each one.

The verdict on the BUIDL token
The BUIDL token earns 87/100 (Tier 2) because it pairs a conservative Treasury-and-repo portfolio with regulated custody, full audit coverage and a compliant distribution model. Its main limits are access (qualified investors only) and a still-young on-chain track record, not the quality of what it holds. If you can access it and understand the smart-contract layer sitting on top of an institutional fund, BUIDL is one of the most credible tokenized treasury options in the market.
