How to Add the Sui Network to Your MetaMask Wallet

About the Sui Network

The Sui network is a decentralized, permissionless Layer 1 blockchain that marks a significant innovation in the cryptocurrency ecosystem. Developed by Mysten Labs, Sui features a unique architecture built on the Move programming language for smart contracts.

Sui’s technical design delivers notable advantages over legacy blockchains. The network supports up to 125,000 transactions per second (TPS), far surpassing Ethereum and other major blockchains. Transaction fees are highly competitive, averaging about $0.001 per transaction, making Sui cost-effective—even for micro-transactions.

The Sui ecosystem is also experiencing rapid growth. Recently, the network has reached several million active wallets and processes millions of transactions daily. Sui’s dApp sector is especially vibrant, with hundreds of registered decentralized applications spanning decentralized finance (DeFi), NFT marketplaces, and blockchain gaming. Total value locked (TVL) in DeFi exceeds $600 million USD, establishing Sui as a major blockchain leader. Innovative projects highlight the network’s potential, driving strong user engagement and significant transaction volumes.

Can You Add Sui to MetaMask?

Many MetaMask users ask whether this popular wallet is compatible with Sui and how to add the network. The answer is nuanced and depends on key technical differences between the platforms.

With over 100 million users, MetaMask dominates as a non-custodial wallet for Ethereum and other blockchains compatible with the Ethereum Virtual Machine (EVM). Sui, however, utilizes a fundamentally different blockchain architecture, which is not EVM-compatible. As a result, users cannot add Sui directly to MetaMask in the standard way.

To overcome this, MetaMask introduced Snaps—JavaScript extensions that let MetaMask connect to blockchain accounts and decentralized applications outside the EVM ecosystem. This technology empowers users to manage non-EVM blockchain assets through MetaMask’s familiar interface.

Users have two main choices: use the Sui MetaMask Snap for a unified experience through MetaMask, or choose a wallet developed specifically for Sui, offering native integration and optimized features.

How to Add Sui to MetaMask Using the Sui MetaMask Snap

Integrating Sui with MetaMask through Snap is straightforward—even for newcomers. The following guide walks you through each step for adding Sui to MetaMask.

Step 1: Access the MetaMask Snaps Directory

Start by opening the official MetaMask Snaps directory. This centralized hub lists all verified Snaps. Search for “Sui” and locate the Sui Snap Wallet by Kuna Labs—the recommended official solution.

Step 2: Install the Sui Snap Wallet

After finding the Sui Snap, click “Add to MetaMask.” MetaMask will display an installation window outlining the necessary permissions. Review these permissions to understand what access is granted. If you’re satisfied, proceed with the installation by following the on-screen prompts.

Step 3: Connect Sui Snap to MetaMask

Once installed, go to the Snap provider’s official website. Select “Connect” to link your Sui Snap Wallet to MetaMask. Complete the connection process using your MetaMask wallet’s instructions. Afterward, your Sui wallet address will appear in the interface. Copy this address using the designated icon for seamless transactions.
