How Do I Convert Between Sei Native and EVM Addresses?

The Problem

I have a Sei native address (sei1...) and need to find its corresponding EVM address (0x...), or vice versa, for use in different wallets, explorers, or development tasks.

Solution Steps

1. Use Block Explorer (Easiest for Users):

   • Go to SeiScan (Native Explorer).
   • Search for your Native (sei1...) address.
   • The corresponding EVM (0x...) address is usually displayed on the address details page. (Vice-versa lookup on EVM explorers like SeiTrace is less consistently available).

2. Use Wallets Supporting Both (e.g., Compass Wallet):

   • Import your seed phrase into a wallet that displays both address types (like Compass).
   • The wallet interface will typically show both the sei1... and 0x... formats for your account.

3. Use @sei-js/js Library (For Developers):

   • Install: npm install @sei-js/js
   • Convert Native to EVM:

     const { getEvmAddress } = require('@sei-js/js');
     const evmAddress = getEvmAddress('YOUR_SEI1_ADDRESS'); 
     console.log(evmAddress);
     

   • Convert EVM to Native:

     const { getSeiAddress } = require('@sei-js/js');
     const seiAddress = getSeiAddress('YOUR_0x_ADDRESS');
     console.log(seiAddress);
     

Explanation and Tips

• ⚠️ Important: Converting address formats does NOT move funds between the Native and EVM environments. See Why Don't I See My Tokens After Converting My Address?
• Consistency: The conversion is deterministic. A specific sei1... address will always map to the same 0x... address and vice versa, as they derive from the same underlying private key.
• Finding Your Own Addresses: If you only have Keplr (Native) and MetaMask (EVM) set up with the same seed phrase, you can use the @sei-js/js library or SeiScan with your known sei1... address to find your linked 0x... address for MetaMask.
