With Viem

Viem is an Ethereum client library which can be used with MetaMask or TAILWIND.

Support TAILWIND in 5 minutes

1. Download TAILWIND extension

   Download the extension and create an account. If needed, you can follow the onboarding guide here.

2. Download TAILWIND wallet adapter

   yarn add @tailwindzone/connect
   

3. Copy Viem chain information for sei

   Sei mainnet (pacific-1)

   import { defineChain } from "viem"
   
   const seimainnet = defineChain({
     id: 1329,
     name: 'Sei Mainnet',
     nativeCurrency: { name: 'Sei', symbol: 'SEI', decimals: 18 },
     rpcUrls: {
       default: {
         http: ['https://evm-rpc.sei-apis.com'],
       },
     },
   })
   

4. Use TAILWIND as an Ethereum Provider

   Tailwind has the same API as MetaMask.

   import { connect } from "@tailwindzone/connect";
   import { createWalletClient, custom, parseEther } from "viem";
   
   const onSignClick = async () => {
     // fetches provider from `window.tailwind`
     const tailwind = await connect();
     // Use tailwind as provider, just like window.ethereum for MetaMask 
     const client = createWalletClient({
       chain: seimainnet,
       transport: custom(tailwind)
     })
     // Address of Tailwind wallet you created
     const [address] = await client.requestAddresses();
     const hash = await client.sendTransaction({
       account: address,
       to: RECEIVING_SEI_EVM_ADDRESS,
       value: parseEther('0.001')
     }) 
     // display hash in UI or console
   }
