B18

B18 is an on-chain banking system built on the Base chain using the B4626 protocol, designed to establish a comprehensive financial infrastructure for Web3 that supports interest accrual, periodic settlement, liquidation, hedging, and payments. Through a unified banking semantics framework, B18 transforms on-chain assets from “passive holdings” into asset accounts with genuine banking attributes, enabling users to participate in on-chain finance just as they would with traditional banking products.
