1. What's the difference between a Web3 wallet and an exchange account?

Many beginners don't understand why there are two "wallets." Here's the explanation:

Exchange account: Your assets are held in custody by the OKX platform. You hold a claim against OKX. If the platform has issues, your assets could be at risk. It's convenient to use and has customer support, but you don't truly "own" the private keys.
Web3 wallet: The assets truly belong to you and are controlled by your private keys. No one (including OKX) can freeze or use your assets. You can interact directly with the blockchain, participate in DeFi, buy NFTs, and use DApps.

Simply put: The exchange account is a bank; the Web3 wallet is your own personal safe.

2. Creating a Web3 wallet

Step 1: Enter the Web3 page

Open the OKX app and tap the "Web3" tab in the bottom navigation.

Step 2: Create a wallet

Tap "Create Wallet" → Set a wallet password → The system generates a seed phrase.

The seed phrase is the most important thing. It's usually 12 or 24 English words. It is the only backup for your wallet. Losing your seed phrase means permanently losing all assets in the wallet. No one (including OKX customer support) can help you recover it.

How to correctly save your seed phrase:

Write it down on paper by hand. Do not take a screenshot or save it in your phone's photo album.

Double-check it after writing to ensure the order and spelling are completely correct.

Store it in a safe place. Do not tell anyone.

It's best to have two backups stored in different locations.

Step 3: Verify the seed phrase

The system will ask you to tap the seed words in order to verify that you have recorded them correctly. Once verified, the wallet creation is complete.

3. Transferring assets from the exchange account to the Web3 wallet

When you first create a Web3 wallet, it's empty. You need to transfer assets from your OKX account.

Path: Exchange Account → Withdraw → Select Coin → Enter your Web3 wallet address → Select the corresponding network → Confirm withdrawal.

Note: You must select the correct network. The Web3 wallet address supports multiple chains. The network you choose for withdrawal must match the chain you want to operate on. For example, if you want to use a DApp on Ethereum, choose the ERC20 network.

4. What can you do with the Web3 wallet?

Cross-chain operations

The OKX Web3 wallet supports 100+ public chains. You can directly swap assets between different chains (cross-chain bridge) without needing to go through an exchange.

Operation path: Web3 page → Cross-chain → Select source chain and target chain → Enter amount → Confirm.

Connecting to DApps

DApps are decentralized applications running on the blockchain, including decentralized exchanges (like Uniswap), lending protocols (like AAVE), blockchain games, etc.

Connection method: Click "Connect Wallet" on the DApp website → Select "OKX Wallet" → Confirm the authorization in the OKX app.

Buying NFTs

The Web3 page has a built-in NFT marketplace where you can browse and purchase NFTs on various chains without jumping to an external platform.

DeFi Yield Farming

You can directly participate in DeFi protocols through the Web3 wallet, providing liquidity to earn yields. The risks are high, so beginners should learn more before operating.

5. Precautions for using the Web3 wallet

Never reveal your seed phrase. Any person or website asking for your seed phrase is a scammer, including those claiming to be OKX customer support. OKX will never ask for your seed phrase.

Be careful with authorizations. When connecting to DApps, some websites may request excessive permissions, allowing the contract to freely use your assets. Confirm the website is the official domain before connecting. Regularly check and revoke unused authorizations after granting them.

Double-check the address before transferring. On-chain transfers cannot be reversed. Sending to the wrong address results in permanent asset loss. Copy and paste the address before transferring, and double-check the first and last few characters.

Select the correct network. Different networks are incompatible. Sending ETH to a BSC address, or selecting the wrong network, can cause your assets to appear "lost." In reality, the assets are still there, but recovering them requires specific methods and is a complex process.

Start with a small amount. When using the Web3 wallet for the first time, transfer a small amount for testing. Confirm the address and network are correct before transferring larger amounts.

6. What to do if you lose your seed phrase?

There is no way to recover it. This is not a limitation of OKX, but the essence of blockchain decentralization—no centralized entity holds your private keys, so no one can help you restore them.

This is why backing up your seed phrase is the single most important thing for a Web3 wallet.

7. Frequently Asked Questions

Q: What's the difference between the Web3 wallet and MetaMask? Their functions are basically the same; both are non-custodial wallets. The OKX Web3 wallet is integrated into the app, supports more chains, and has a more user-friendly interface. MetaMask is a standalone plugin, more convenient to use on a PC browser. Both can import the same seed phrase for mutual use.

Q: Are the assets in the Web3 wallet safe? As long as your seed phrase is safe, your assets are safe. The risk of a Web3 wallet doesn't come from the platform, but from your own actions—seed phrase leaks, connecting to phishing websites, and authorizing malicious contracts are the most common causes of loss.

Q: Can I buy coins directly in the Web3 wallet? Yes. The OKX Web3 wallet has a built-in swap feature, allowing you to exchange one coin for another directly. You can also buy coins directly through the C2C channel.

Q: Does the Web3 wallet require identity verification? No. The Web3 wallet is completely decentralized, not linked to your OKX account, and does not require KYC.

Q: Can I create multiple Web3 wallets under one OKX account? Yes. The OKX Web3 wallet supports creating multiple wallets or importing existing ones, suitable for managing different purposes separately.
