protocol identification
two sourcesBlackRock BUIDL is the BlackRock USD Institutional Digital Liquidity Fund, a tokenized money-market/RWA yield protocol issued with Securitize. Public sources place inception/launch in March 2024 (BlackRock’s March 2024 launch on Ethereum; RWA.xyz lists an inception date of 2024-03-20). The official web presence is on Securitize/BlackRock materials, with protocol-level listings and analytics pages identifying the fund as BUIDL. It is multichain on Ethereum, Aptos, Arbitrum, Avalanche, BSC, OP Mainnet, Polygon, and Solana. The protocol’s native token is BUIDL; no separate governance token was identified. Main contract/address evidence available from public cross-checks includes: Ethereum token contract 0x7712c34205737192402172409a8F7ccef8aA2AEc (Etherscan), plus share-class / network addresses reported in BlackRock/Securitize press materials for Aptos, Arbitrum, Avalanche, OP Mainnet, Polygon, and a Solana token address. However, because Dune/on-chain verification is unavailable in this run, explorer verification status for a full chain-by-chain main-contract list is: Not verifiable as of 2026-08-30. The best directly verifiable explorer confirmation I found is the Ethereum Etherscan entry for the BUIDL token contract; other addresses were surfaced by press release and aggregators, but I could not cross-check them on-chain here. Fork lineage: BUIDL is not presented as a forked DeFi protocol; it is a BlackRock/Securitize tokenized fund with multichain share classes. I found no evidence of upstream fork ancestry, no public claim of “forking” another yield protocol, and no separate fork audit trail in the sources reviewed. Therefore, fork status and any malicious-modification history in similar forks are Not verifiable as of 2026-08-30. The changes across chains appear to be new share-class deployments and interoperability expansion, not protocol fork modifications.
