OISY Wallet — One wallet. Every chain.
Developer: DFINITY Foundation · Category: Finance · Last updated: March 2026
OISY gives you a single interface to hold and manage assets across ICP, Ethereum, Bitcoin, and Solana. It replaces seed phrases and browser extensions with network-level key management — your keys are split across independent nodes and never exist in one place. Connect to apps, send and receive tokens, and view your portfolio without installing anything. Just open the browser and go.

Frequently asked questions
- Is OISY Wallet really free?
- Yes. OISY has no premium tier, no subscription, and no usage caps. It's operated as a public utility on the Internet Computer.
- What chains does OISY support?
- ICP, Bitcoin (ckBTC), Ethereum (ckETH), and Base. The BTC and ETH support is native via chain-key cryptography — not wrapped tokens.
- Do I need a seed phrase?
- No. OISY uses WebAuthn passkeys. Register multiple passkeys upfront (phone, laptop, hardware key) for recovery — any one can restore access.
