Bolt Finance is a decentralized finance (DeFi) protocol built on the Ethereum blockchain that allows users to earn interest on their crypto assets through lending and borrowing. The platform also offers liquidity pools for users to provide liquidity for trading pairs and earn trading fees. Bolt uses smart contracts to automate the lending and borrowing process, making it more efficient and accessible than traditional financial services. The platform also has a governance token called BOLT, which can be used to vote on protocol upgrades and proposals.
