Web3 Wallets
Introduction to Web3 Wallets
Learn about Cobo Portal’s Web3 Wallets, a secure solution for managing digital assets with advanced security and compliance features.
Web3 Wallets are a sub-wallet type of Custodial Wallets designed for interacting with the Web3 ecosystem, including DeFi, NFTs, and dApps. With Web3 Wallets, you can perform smart contract calls, asset approvals, and message signing, without managing private keys or deploying infrastructure.
Unlike Asset Wallets, which focus on centralized fund management, Web3 Wallets allow you to independently control each address. You can explicitly specify the source address for each transaction or interaction, giving you greater flexibility and clarity.
You can access Web3 Wallets through the Cobo Portal web interface or via WaaS 2.0 API. You can also use the Cobo Connect browser extension to securely connect your wallets to dApps and perform on-chain actions.
