import { fromViemClient, viemWallet } from '@chainlink/ccip-sdk/viem'

const account = privateKeyToAccount('0x...')
const walletClient = createWalletClient({
  chain: mainnet,
  transport: http('https://eth.llamarpc.com'),
  account,
})

const chain = await fromViemClient(publicClient)
const request = await chain.sendMessage(
  router,
  destChainSelector,
  message,
  { wallet: viemWallet(walletClient) }
)

Browser wallet (MetaMask)

TypeScript

import { createWalletClient, custom } from 'viem'
import { mainnet } from 'viem/chains'
import { viemWallet } from '@chainlink/ccip-sdk/viem'

const walletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum),
  account: connectedAccount,
})

// Works with injected providers!
const signer = viemWallet(walletClient)
