Learn how Web3 wallets differ from exchange accounts, and check downloads, supported networks, recovery backups and token approvals.
What is a Web3 wallet, and which wallets are listed?
A Web3 wallet can manage on-chain addresses, sign transactions and connect to decentralized apps. This site lists wallets from OKX, Binance, Bitget and Coinbase. Compare supported networks, recovery methods and the features you need.
How do OKX and Binance Web3 wallets differ from exchange accounts?
An exchange account gives you access to services such as spot and futures trading on that platform. A Web3 wallet manages on-chain addresses and assets and can connect to apps. Check supported networks, distribution and recovery methods, and read the purpose of each signature or approval.
Where can I check a Web3 wallet download?
Find the wallet card and choose Android or iOS. Check the app name and developer on the official wallet site or app store. When moving an existing wallet, make sure your recovery method works before migrating.
How do I check Web3 wallet permissions?
Use your wallet's approval manager to see which apps have permission and what spending limits they have. Confirm the network and contract before changing old approvals. Review each signature request and keep your recovery phrases and private keys private.
How should I back up a Web3 wallet?
Check whether your wallet uses a recovery phrase, private key or another recovery method, then follow its official backup instructions. Keep recovery information somewhere secure that you control. Avoid sharing it through chat, email or unfamiliar websites.
How do wallet transfers, signatures and token approvals differ?
A transfer usually sends an asset to another address. A signature can prove address control or consent to an operation. A token approval grants a specified contract a spending allowance. Check the requester, token, amount and network before confirming.
