What is SecondFi?

SecondFi is a self-custodial, multichain wallet designed to provide a seamless Web3 experience. It allows you to manage assets across multiple blockchains — including Cardano, Ethereum, BNB Smart Chain, Base, Avalanche, Bitcoin, Solana, and Tron — all from a single unified interface.

As a self-custodial wallet, you have complete control over your private keys and funds. SecondFi does not hold your assets or have access to your wallet. You are always in control.
