OISY
Browser-based self-custody wallet on the Internet Computer for BTC, ETH, SOL and ICP, incubated by DFINITY
Contact Information
About the Company
OISY is a browser-based, self-custodial multi-chain wallet powered by Internet Computer's chain fusion technology and incubated by the DFINITY Foundation. The whole wallet application is stored on-chain and served directly to the browser, so no extension or mobile app is needed. Sign-in uses Internet Identity, which lets the same wallet be reached from linked devices.
Keys are not held by any single party: key shares are distributed across ICP replica nodes and signatures are produced with threshold ECDSA. Supported networks include Bitcoin, Ethereum and ICP, with version 1.5 adding Solana, Polygon, BNB Chain and Base without bridges. WalletConnect is integrated for services such as Uniswap, and version 1 went live in February 2025.
