How to Link Your Sei and EVM Addresses

To use your EVM address alongside a native Sei address, you will need to link your wallet through the wallet-linking portal. To do this,

1. Visit the linking portal at https://app.sei.io/.

2. On the platform dashboard, click Connect Wallet to access your account overview.

3. Complete the captcha on the wallet-linking section to activate the Link Addresses button.

4. Click on Link Addresses to start the process.

5. A prompt will be sent to your MetaMask wallet requesting you to sign a transaction. Approve the request to continue.

This is only a signing request to confirm your identity and doesn’t involve any charges.

6. After the linking process is completed your second wallet address will be shown.

Note that both wallets are now connected to the same Sei account and can be used interchangeably.

You can now access both EVM and native Sei applications.

Connect to Sei Network dApps With MetaMask

To demonstrate how to connect to an EVM Sei dApp using your MetaMask wallet, we will visit YEI Finance – a decentralized lending platform on the SEI network. 

To connect to the application;

1. Visit the platform and click Connect Wallet from the dashboard.

2. Select MetaMask and approve the connection request to complete.

3. You can interact with the dApp as per normal, where requests for approval will be sent as a prompt to your MetaMask wallet.

FAQs on Connecting to Sei With MetaMask

As Sei Network is now an EVM blockchain with the launch of Sei V2, understanding the EVM side of the network and how it relates to the native Sei Network may be confusing. We’ll look at some common queries around EVM and Sei native addresses and transactions.

EVM vs. Sei Addresses

After linking your EVM wallet via the wallet-linking portal, you receive a second address; this is a Sei native address. Your EVM address (that starts with 0x) and SEI address (that starts with Sei1) are connected to each other. During the wallet creation process, the protocol generates a native SEI address using your wallet’s public key. 

Both addresses will still point to the same account on the Sei ledger. Depending on the application you are using, only one of the wallets will be shown, but your balances on both wallets will be the same and every transaction will be recognized. That is, if you are visiting a native Sei dApp, your Sei address will be automatically used, and your EVM address will be used to connect to EVM dApps. Both addresses can be used as the recipient address when transferring funds to your wallet.

EVM Transactions vs. Sei Native Transactions

The key difference between a Sei EVM transaction and a native Sei transaction is on the backend operation. From the user’s perspective, both transactions feel the same. A native Sei transaction targets a Sei pre-compiled contract while an EVM transaction assumes the normal sequence of other EVM transactions. To enable users to run both transactions from their MetaMask wallet, the dApp smart contract developer will need to adjust the application to ensure that MetaMask transactions target the precompiled contract.

Final Thoughts

Sei V2’s parallelized EVM adopts the smart contract execution system used by the Ethereum network to improve its performance and cost-effectiveness. The dual network architecture means that the native Sei and the EVM side of Sei Network exist as an efficiently connected system. Network users now will be able to easily alternate between both systems and access a wider range of dApps.
