Web-first network-resident digital asset wallet
Crypto's traditional phone app and browser-extension wallets are insecure, and can be blocked by Big Tech. In complete contrast, your OISY Wallet lives fully-onchain, and is accessed via the web. OISY uses ICP 'chain key' technology to consolidate chains, identities, and primitives — manage ICP, Bitcoin, Ethereum, Solana, and perform DeFi actions, all in one place.
Fully on-chain architecture
The entire OISY application is stored on-chain and served directly to your browser via the Internet Computer, ensuring a decentralized and tamper-proof environment. No browser extensions or downloads required—just access your wallet directly from any web browser.
Network custody security
Leveraging the Internet Computer's advanced cryptography, OISY introduces network custody, eliminating the need for users to handle private keys directly. Assets are controlled by a distributed cryptographic threshold protocol, ensuring no single entity can gain full control.
Multichain compatibility
Manage Bitcoin, Ethereum, ICP, Solana, and more within a single, cohesive interface. OISY integrates WalletConnect protocol, enabling interaction with a wide range of established Web3 services and dApps across multiple blockchains.
Limitless access
Access your wallet across all devices linked to your decentralized identity through Internet Identity. Use biometric authentication like FaceID or TouchID for seamless, password-free sign-ins from smartphones, tablets, or desktops.
What is OISY Wallet?
OISY Wallet was incubated at DFINITY Foundation to simplify DeFi navigation. Initially built for ICP, it quickly evolved to unify primitives across all DeFi chains. Today, OISY is the world's first fully on-chain digital asset wallet, consolidating chains, identities, and primitives into a single immutable DeFi terminal.
Unlike traditional wallets that require browser extensions or downloads, OISY operates directly from your web browser, enabling secure, passkey-enabled sign-ins without reliance on third-party servers. This approach eliminates common security vulnerabilities associated with browser extensions and provides a more streamlined user experience.
What is OISY Wallet?
Powered by ICP's Chain Fusion technology, OISY delivers security, transparency, and scalability by default. Chain Fusion enables OISY to natively interact with Bitcoin, Ethereum, and other major blockchains without bridges or wrapped tokens, providing true multichain functionality.
Getting started
Getting started with OISY is simple. Navigate to OISY.com and click 'Open or Create' to begin. You'll create an Internet Identity, which serves as your decentralized identity across the Internet Computer ecosystem. Once set up, your OISY Wallet is automatically generated and ready to use.
Connecting to dApps
OISY Wallet supports seamless connections to decentralized applications via WalletConnect and Internet Computer protocols. Whether you're trading on Uniswap, interacting with ICP dApps, or exploring DeFi platforms, OISY provides a unified interface for all your Web3 activities. Developers can integrate OISY into their applications using IdentityKit for React or other ICP building blocks.
Revolutionary technology for DeFi
OISY Wallet represents a paradigm shift in digital asset management. Traditional wallets require users to manage private keys, install browser extensions, and juggle multiple wallets for different blockchains. OISY eliminates these complexities through its innovative network custody model and Chain Fusion technology.
The network custody approach means that private keys don't physically exist in a single location. Instead, assets are controlled by a distributed cryptographic threshold protocol on the Internet Computer. This design ensures that no individual entity, including OISY itself, can gain full control over your keys, providing unprecedented security guarantees.
Powered by Chain Fusion technology
Chain Fusion technology enables OISY to interact directly with Bitcoin, Ethereum, and other major blockchains without requiring bridges or wrapped tokens. This native multichain capability means you can send Bitcoin, swap Ethereum tokens, and interact with ICP dApps—all from a single wallet interface, with all transactions secured by the Internet Computer's tamperproof infrastructure.
Internet Identity integration
Internet Identity integration provides a seamless, password-free authentication experience. Your identity is cryptographically secured and can be accessed from any device using biometric authentication or security keys. This eliminates the risk of password-based attacks and provides a consistent experience across all your devices.
Developer-friendly integration
For developers, OISY offers comprehensive integration tools including IdentityKit for React, enabling easy wallet connections in dApps. The wallet supports ICP signer standards and WalletConnect protocol, making it compatible with the entire Web3 ecosystem. Whether building on ICP or integrating with Ethereum-based dApps, OISY provides the tools needed for seamless user experiences.
