Is BlackRock BUIDL Safe?
Risk Grade: C+ (37/100)
BlackRock BUIDL is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
Lower risk — backed by BlackRock and US Treasuries, but cross-chain bridge exposure adds a layer of risk unusual for a money market fund
A tokenized money market fund from BlackRock that lets you earn interest on US Treasury bills through a blockchain token. It manages $1.68B across five blockchains and is the second-largest tokenized fund in DeFi. Its B grade reflects strong institutional backing offset by cross-chain bridge risk and redemption bottlenecks.

Key Risks for BlackRock BUIDL Users
Your money moves across five blockchains through Wormhole bridges. If any bridge gets hacked, fake tokens could be created and your real tokens could be frozen for months
In August 2025, $447M left the fund in one month. If too many people try to cash out at once, you could wait days to get your money back
Circle's competing product already passed BUIDL in size. If BlackRock decides this fund isn't worth running, you'd be forced out with limited alternatives
Top Risk Factors
- •Multi-chain bridge risk: BUIDL deploys across Ethereum, Solana, Polygon, BNB Chain, and Avalanche via Wormhole; a bridge exploit could mint unbacked tokens or freeze legitimate holders' assets across chains
- •Redemption capacity stress: August 2025 saw $447M in net outflows in one month; operational infrastructure (Securitize platform + manual compliance) may not scale to handle true institutional panic redemptions
- •Institutional concentration: overtaken by Circle USYC in Jan 2026 suggests competitive vulnerability; if BlackRock winds down BUIDL due to unprofitability, holders face forced exit with limited alternatives
