What is OKX Web3 Wallet?
OKX Web3 Wallet is a non-custodial multi-chain wallet built directly into the OKX app and available as a standalone browser extension. Unlike exchange wallets where OKX holds your keys, the Web3 Wallet gives you full control over your private keys and seed phrase.
It combines the convenience of a centralized exchange with the sovereignty of self-custody. You can interact with DeFi protocols, swap tokens on DEXes, bridge assets across chains, buy and sell NFTs, and explore DApps - all from a single interface without leaving the OKX ecosystem.
Key Features
Multi-Chain Support (80+ Chains)
Access Ethereum, Solana, BSC, Polygon, Arbitrum, Optimism, Avalanche, Base, Sui, Aptos, TON, and 70+ more chains from a single wallet interface. No need to manage separate wallets for each blockchain.
Built-in DEX Aggregator
Swap tokens with the best rates by aggregating prices from hundreds of decentralized exchanges across all supported chains. The aggregator automatically splits orders to minimize slippage and maximize your output.
Cross-Chain Bridge
Move assets between different blockchain networks seamlessly. The built-in bridge finds the fastest and cheapest routes for cross-chain transfers, supporting major assets across all connected chains.
DApp Browser
Discover and interact with thousands of decentralized applications directly within the wallet. From DeFi lending protocols to GameFi apps, access the full Web3 ecosystem without switching tools.
NFT Marketplace
Browse, buy, sell, and manage NFTs across multiple blockchains. The integrated NFT marketplace supports Ethereum, Solana, Polygon, and other major NFT ecosystems with real-time pricing and rarity data.
How to Set Up OKX Web3 Wallet
Download the OKX App or Extension
Get the OKX app from the App Store or Google Play, or install the OKX Web3 browser extension for Chrome, Firefox, or Brave. Register with TRADEOFF20 for 20% fee discount on the exchange side.
Create or Import a Wallet
Create a new wallet (OKX generates a seed phrase for you) or import an existing wallet using your seed phrase or private key. You can also import hardware wallet connections for added security.
Securely Backup Your Seed Phrase
Write down your 12 or 24-word seed phrase on paper and store it in a secure, offline location. Never share your seed phrase with anyone. Never store it digitally (no screenshots, no cloud storage, no notes apps).
Connect to DApps and Start Exploring
Your wallet is ready. Browse DApps, swap tokens, bridge assets, or explore NFTs directly from the wallet interface. Fund your wallet by transferring from your OKX exchange account or from external wallets.
Supported Blockchain Networks
OKX Web3 Wallet supports 80+ blockchain networks. Here are the most popular ones:
Plus 70+ additional chains including Fantom, Cronos, Klaytn, Tron, Cosmos ecosystem chains, and more. New chains are added regularly.
OKX DEX Aggregator: Best Swap Rates
The OKX DEX aggregator scans hundreds of decentralized exchanges across all supported chains to find you the absolute best swap rate. Instead of manually checking Uniswap, SushiSwap, PancakeSwap, and others, the aggregator does it automatically.
For large swaps, the aggregator intelligently splits your order across multiple DEXes to minimize price impact and slippage. This means you consistently get more tokens for your money compared to using any single DEX directly.
Cross-Chain Bridge
Need to move your ETH from Ethereum to Arbitrum? Or transfer USDC from Polygon to BSC? The OKX cross-chain bridge handles this seamlessly. Simply select the source chain, destination chain, and the asset to bridge.
The bridge automatically finds the optimal route by comparing multiple bridge protocols for speed, cost, and reliability. You can see estimated time, fees, and the amount you will receive before confirming the transaction.
Security Features
MPC Wallet Technology
OKX offers Multi-Party Computation (MPC) wallet as an option. MPC splits your private key into multiple parts stored on different devices, eliminating single points of failure. Even if one device is compromised, your funds remain safe.
Seed Phrase Security
Your seed phrase is encrypted and stored locally on your device. OKX never has access to your keys. The wallet includes a secure backup flow that guides you through properly saving your recovery phrase offline.
Biometric Authentication
Protect wallet access with Face ID, Touch ID, or device PIN. Every transaction requires biometric confirmation, preventing unauthorized access even if someone gains physical access to your unlocked phone.

Pro Tips for OKX Web3 Wallet
Always Backup Your Seed Phrase
Write your seed phrase on paper (not digitally) and store it in multiple secure locations. Consider using a fireproof safe or a metal seed phrase backup. Losing your seed phrase means losing access to your wallet permanently.
Use MPC for Enhanced Security
Enable MPC wallet for an extra layer of security. MPC eliminates the single point of failure of traditional seed phrases by distributing key shares across multiple devices. Even if one device is compromised, your funds remain secure.
Check Gas Fees Before Swapping
Gas fees vary significantly throughout the day and across chains. The OKX DEX aggregator shows estimated gas fees before you confirm. For large swaps, consider using L2 chains like Arbitrum or Base for significantly lower gas costs.
