BlackRock USD Institutional Digital Liquidity Fund

BlackRock USD Institutional Digital Liquidity Fund, ticker BUIDL, is a tokenized money-market fund issued by the world's largest asset manager and designed to give institutional investors access to a USD-denominated, yield-bearing fund through blockchain-based tokens. Each token is intended to maintain a stable value of one US dollar, so it is not meant to appreciate in price but rather to let holders keep assets on-chain while earning the returns of the underlying fund. The product targets institutions that want the operational convenience of digital assets without abandoning the credit quality associated with traditional short-duration cash instruments.

Each BUIDL token represents a fractional interest in the fund and is engineered to trade at exactly one dollar, with the fund itself holding assets such as US Treasury bills and repurchase agreements to support that peg. The token exists across multiple blockchain ecosystems — including Ethereum, Solana, Avalanche, Polygon, Arbitrum, BNB Chain, and Optimism — so transfers and settlements can occur on-chain rather than through conventional clearinghouses. No consensus algorithm is recorded in the available data, and the block time is listed as zero, reflecting that BUIDL is a fund wrapper rather than a standalone blockchain protocol.

The data stored for BUIDL does not include a protocol fee stream, revenue figures, or any record of fees collected, distributed, or retained, so fee-based measures common on this site are not applicable here. Returns to token holders, if any, would come from the yield generated by the fund's underlying assets and would be governed by the fund's legal documentation rather than by an on-chain mechanism tracked in this dataset. The circulating supply stands at 2,793,670,061.06 tokens on a point-in-time basis, and the 30-day change in that figure is 5.967656, reflecting net issuance or redemption activity over that period.
