Although BUIDL, USDC, and USDT are quoted 1:1 with the dollar on-chain, their goals are opposite. While USDC and USDT operate as digital dollars with no restrictions for daily payments and commercial liquidity, the issuers keep the returns from the reserves. BUIDL, from BlackRock, operates as a regulated security token (Security Token) under the SEC that invests 100% of its fund in U.S. Treasury, distributing directly a passive yield (~5% annually) to the wallets of its holders. BUIDL turns cash into productive collateral for institutional treasuries; unlike traditional stablecoins’ open access, it requires KYC verification and restricts transfers only between pre-approved wallets, while also enabling immediate liquidity of $1 NAV and 24/7 redemption into USDC via Circle.
