How to Add the Sui Network to Your MetaMask Wallet

Introduction to the Sui Network

The Sui network is a decentralized, permissionless Layer 1 blockchain developed by Mysten Labs. Renowned for high throughput and low latency, Sui leverages the Move smart contract language, enabling superior scalability and lower transaction costs compared to Ethereum and Solidity. Official reports indicate Sui processes up to 125,000 transactions per second, with average fees around $0.001.

Currently, Sui boasts over 8 million active wallets and processes about 10 million daily transactions, reflecting robust market activity. Its ecosystem supports more than 500 decentralized applications (dApps), including DeFi protocols, NFT marketplaces, and gaming platforms. The total value locked (TVL) in Sui’s DeFi protocols exceeds $679 million, ranking 13th worldwide among blockchains. For example, Cryptomon, an NFT-based gaming app, attracts large numbers of users for trading and participation within the Sui ecosystem.

Can I Add Sui to MetaMask?

MetaMask primarily supports Ethereum and EVM-based blockchains (Ethereum Virtual Machine). Because Sui employs a unique blockchain architecture and is not EVM-compatible, you cannot directly add Sui to MetaMask. However, you can manage Sui assets in two ways: first, by using the Sui MetaMask Snap feature, which connects you directly to Sui dApps and enables asset management through MetaMask; second, by using dedicated wallet apps built specifically for the Sui network.

MetaMask Snaps is an innovative solution allowing users of non-EVM blockchains to manage assets via the MetaMask interface. Snaps are authorized JavaScript applications that use the MetaMask infrastructure to connect to blockchain accounts and dApps. Sui MetaMask Snap lets Sui investors manage assets directly within MetaMask, eliminating the need for a traditional Sui wallet and reducing entry barriers.

How to Use Sui MetaMask Snap to Add Sui to MetaMask

Step 1: Access the MetaMask Snaps Directory

Start by visiting the official MetaMask Snaps directory. Enter "Sui" in the search bar, and the system will display relevant Snap applications. Select the Sui Snap Wallet developed by Kuna Labs to ensure you’re using an official, approved version.

Step 2: Install Sui Snap Wallet

On the Sui Snap Wallet page, click "Add to MetaMask." The system will redirect you to the MetaMask wallet app. Follow the installation prompts provided by MetaMask. During installation, the system will request you review and accept the necessary Snap permissions. Carefully check these requests, confirm their accuracy, and click to accept and proceed.

Step 3: Connect Sui Snap to MetaMask

After installing, go to the official Snap provider’s website to configure the connection. Click "Connect" on the website and follow MetaMask’s instructions to verify your identity. Once connected, your Sui Snap wallet is ready. You can find your wallet address at the top of the wallet interface and click the "Copy" icon to copy it for later use.

How to Use Sui MetaMask Snap

Connecting to a dApp

First, access a decentralized app that supports Sui, such as DeFi platforms like Cetus Finance. On the home page, click "Connect Wallet." In the wallet selection menu, choose "Sui MetaMask Snap," then follow MetaMask prompts for identity verification and authorization. Once connected, you can perform various transactions on the dApp.

Sending Tokens

From the Sui Snap wallet homepage, click "Send" to open the token sending interface. Enter the recipient’s Sui network address and select the token type from the dropdown menu. After entering the amount, click "Send." MetaMask will display a transaction confirmation window. Review the details—such as gas fees and recipient address—then click to approve and finalize the transaction.

Staking Tokens

Click the "Stake" button on the wallet homepage to access the staking interface. Available staking options will be shown; select "Stake SUI." Choose a validator from the Sui network list and enter the number of SUI tokens to stake. Click "Stake Now," and MetaMask will prompt you to approve the transaction. Once confirmed, your staking transaction is complete.

Alternative Sui Web3 Wallets

Beyond MetaMask Snap, you can choose from several independent crypto wallet apps built for Sui, offering streamlined interfaces and optimized features for the network.

Sui Wallet

Sui Wallet is an officially developed, professional wallet with a simple, intuitive design. It offers mobile apps (iOS and Android) and a browser extension. Visit the official Sui Wallet website to download the appropriate version for your device. After installation, follow on-screen prompts to create a new wallet. The system generates a 24-word mnemonic phrase—the key for wallet recovery—which must be kept secure. For maximum safety, record the mnemonic on a physical medium and avoid digital storage to reduce hacking risks. Once set up, you can use the built-in exchange to buy, sell, or swap Sui tokens, or purchase Sui on major exchanges and transfer them to your wallet.

Conclusion

While Sui cannot be directly integrated into MetaMask due to its unique blockchain architecture, the Sui MetaMask Snap feature allows you to manage Sui assets within the familiar MetaMask environment. By following the steps outlined to install Sui MetaMask Snap, you can seamlessly connect to Sui ecosystem dApps, send tokens, and participate in staking operations. This innovation dramatically improves cross-chain asset management and delivers a practical experience for Sui investors. If you prefer a simpler workflow, you can also choose purpose-built Sui wallets such as Sui Wallet, Suiet, Fewcha, or SafePal, selecting the most suitable solution for your needs to engage with the Sui ecosystem.
