Can You Add Sui to MetaMask?

You can add the Sui blockchain to your MetaMask wallet through the Sui MetaMask Snap, which lets you connect to Sui dApps. You can also use the Sui MetaMask Snap to store, send, and stake SUI.


Key Takeaways

  • MetaMask Snaps allow non-EVM blockchain account holders to manage their assets from the MetaMask wallet interface.

  • A Snap is a permissioned javascript application that utilizes the MetaMask infrastructure to connect to blockchain accounts and also to decentralized applications. It functions like a browser extension.

  • Thanks to the MetaMask Snap version of the Sui wallet, Sui investors can now manage their assets without installing the traditional Sui wallet, where their MetaMask wallet is used to control approvals on the Sui blockchain.


Sui to MetaMask

Sui is a non-EVM Layer 1 developed by Mysten Labs with the Move programming language. It runs the delegated Proof of Stake (DPOS) consensus algorithm and claims to offer super-fast transaction processing speed and a relatively low transaction fee. Sui claims up to 125,000 TPS and about $0.001 fee per transaction. According to data from the network explorer, over 8 million unique wallets are active on the network, and over an average of 10 million transactions are executed on the network daily.

Despite a few similarities with the Ethereum network, users of the Sui blockchain cannot manage their assets from single-chain EVM wallets like MetaMask. This connection is only possible through a MetaMask Snap. This is the same for other non-EVM networks, like Solana. Snaps are a recent development by MetaMask and are opening interoperability opportunities for MetaMask and the wider crypto space. 

What Are MetaMask Snaps?

MetaMask Snaps are currently available for the MetaMask browser extension only. MetaMask snaps extend the functionalities of the MetaMask wallet. They are third-party applications that utilize the MetaMask wallet to function, requiring permission from the wallet owner. Currently, there are three categories of MetaMask Snaps.

Transaction analysis Snaps like Tenderly gives users an in-app explanation of the transaction they are about to execute, offering users knowledge of the security and a preview of the result of the transaction.

Interoperability Snaps bridge the gap between MetaMask wallet and non-EVM networks. It enables users on other networks including Bitcoin and blockchains like Sui, Cosmos, and Solana to manage their assets via the MetaMask wallet. Other use cases like transaction notifications can also be developed using MetaMask Snaps.

This article discusses the Sui Snap Wallet and how Sui investors can manage their assets using the Snap.

How to Use Sui MetaMask Snap

Now, let’s look at how you can use the Sui Snap Wallet to connect to dApps, send tokens, and stake. 

Connect to a dApp via Sui MetaMask Snap

As a Layer 1 network, Sui supports multiple dApps. It is designed to support DeFi, NFT, and utility applications.

FAQs Around the Sui MetaMask Snap

Here are some common questions from users about MetaMask Snap versions of non-EVM wallets, including the Sui wallet MetaMask Snap.

Can you manage your Sui assets within MetaMask?

The interface of the Sui wallet MetaMask Snap is similar to the MetaMask wallet interface, however, just like any other wallet Snap, your assets aren’t managed within the MetaMask wallet. MetaMask only functions as a connectivity medium for your Sui Snap Wallet. 

Your assets are managed within the Sui wallet, but as a Snap, the connectivity is powered by the MetaMask wallet. To manage your assets, you will need to visit the wallet provider’s platform (https://suisnap.com/, for the featured wallet). Just like browser extensions run on another application (the browser), the wallet Snap runs on the MetaMask wallet.

Custodianship

Your Sui wallet MetaMask Snap keys are managed by your MetaMask wallet. That is, the Suisnap doesn’t provide you with a private key. To export your Sui Snap wallet, you will need to export your MetaMask wallet and connect to your wallet from the Sui wallet provider’s interface.

What happens when I uninstall the Sui MetaMask Snap?

Once you uninstall the Snap, it becomes unavailable and stops interacting with your MetaMask wallet. However, your account is retained and still attached to your MetaMask wallet. To recover your Sui Snap Wallet account, re-install the snap on the same MetaMask wallet.

Final Thoughts

Follow the procedure in this article to start using the Sui MetaMask Snap. The MetaMask Snap version comes in handy for investors who wish to manage their assets without necessarily downloading multiple wallets. However, it is important to note the caveats that might be involved, in comparison to downloading a conventional blockchain-specific wallet which has a clearer key and asset management arrangement. 

That said, the MetaMask Snap version works just as well; you will be able to carry out most of the key operations using it. Note that the activities shown in this article aren’t exhaustive of what you can do with your Sui MetaMask Snap, but ensure that you understand other procedures enough to perform them without running into issues. In fact, the Sui Snap Wallet also supports the Sui testnet, so you can familiarize yourself with the procedures using testnet Sui.

Having said this, note that this article only guides readers through the process of using the Sui wallet MetaMask Snap and is not financial advice. Always do your own research before interacting with any protocols and transferring your funds.
