What is Sei Devnet?

Sei Devnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on Sei Devnet once you add the network configuration.

Why do you need to add Sei Devnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Sei Devnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

How to add Sei Devnet to your wallet

  1. 1

    Click Add to wallet

    Press the "Add to wallet" button above. MetaMask, OKX Wallet, Rabby Wallet or Trust Wallet will show a popup asking you to confirm adding the Sei Devnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the Sei Devnet network details: Chain ID 713715, native token SEI. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

    Switch to the new network

    After confirming, your wallet automatically switches to Sei Devnet. You can start transacting right away — you will need SEI to pay gas fees.

Frequently asked questions

Is it safe to add Sei Devnet to MetaMask?▾
Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.
What is Sei Devnet Chain ID?▾
The Chain ID of Sei Devnet is 713715. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need SEI tokens to use Sei Devnet?▾
Yes. Every transaction on Sei Devnet requires SEI to pay gas fees. You can purchase SEI on exchanges and bridge it to Sei Devnet, or use a faucet if this is a testnet.
What is the Sei Devnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Sei Devnet blockchain — sending transactions, reading balances, and checking state. One popular Sei Devnet RPC is https://evm-rpc-arctic-1.sei-apis.com. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Sei Devnet already exists when I click Add — what do I do?▾
That's completely normal. If Sei Devnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Sei Devnet but the network won't load — what's wrong?▾
The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
