How to Add Sui Network to MetaMask Wallet

Learn how to add the Sui Network to MetaMask using the Sui MetaMask Snap. Follow our step-by-step guide to connect to Sui dApps, manage assets, and more.

Summary: MetaMask does not support the Sui blockchain due to its compatibility with Ethereum and EVM-based networks only. However, Sui users can use the Suiet Wallet, which is tailored for managing Sui assets.

The MetaMask wallet is one of the most popular non-custodial wallets for Ethereum and EVM-compatible blockchains. With over 100 million users, It is a go-to choice for managing crypto assets and interacting with decentralized applications (dApps). However, adding the Sui Network directly to MetaMask is not feasible due to their different underlying technologies.

Sui Network is a decentralized, permissionless Layer 1 blockchain known for its high throughput and low latency. Developed by Mysten Labs, Sui uses the Move smart contract programming language, offering higher scalability and lower transaction costs than Ethereum and Solidity, Ethereum’s smart contract programming language. Sui claims up to 125,000 transactions per second (TPS) and a transaction fee of about $0.001. As of May 2024, Sui Network has over 8 million active wallets and processes an average of 10 million transactions daily.

As of May 2024, Sui Network supports over 500 dApps, including DeFi platforms, NFT marketplaces, and gaming applications. Sui’s DeFi TVL is over $679 million at the time of writing, making it rank 13 among leading blockchains. An example of a popular project on Sui is Cryptomon, an NFT-based game that has seen significant user engagement and transaction volume.

Sui Network uses a unique blockchain architecture that is incompatible with the Ethereum Virtual Machine (EVM), which MetaMask supports. This incompatibility means that Sui cannot be directly integrated into MetaMask. Instead, you have two options:

Sui MetaMask Snap: You can add the Sui blockchain to your MetaMask wallet through the Sui MetaMask Snap. This Snap lets you connect to Sui dApps and manage your Sui assets directly from MetaMask.
Sui Wallets: You can use a wallet specifically designed for Sui.
