What is OISY?

OISY is a self-custody web wallet incubated by the DFINITY Foundation. Users sign in with Internet Identity instead of a seed phrase, then manage assets across Bitcoin, Solana, Ethereum, ICP, and major EVM chains. Built-in features include cross-chain swaps, multi-network sending, and a privacy-preserving AI assistant; the wallet itself runs fully on-chain on the Internet Computer.
