Function Call

Transfer all tokens

ethers.js

    senderSigner: signer,
    chainId: number,
    receiverAddress:"0x786E6045eacb96cAe0259cd761e151b68B85bdA7"
  });

viem

import { createWalletClient, custom } from 'viem'
import { mainnet } from 'viem/chains'

const walletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum!),
})
 
const [account] = await walletClient.getAddresses();

await aarcSDK.executeMigrationGasless({
    senderSigner: walletClient,
    chainId: number,
    receiverAddress:"0x786E6045eacb96cAe0259cd761e151b68B85bdA7",
    account: account
  });

Transfer-specific tokens

    chainId: 137,
    transferTokenDetails:[
    {
        tokenAddress:"0x2271e3Fef9e15046d09E1d78a8FF038c691E9Cf9",
        // .toString(16) is to convert TOKEN_AMOUNT to hex in string format
        amount:TOKEN_AMOUNT.toString(16)   
    },
    {
      tokenAddress:"0x932ca55b9ef0b3094e8fa82435b3b4c50d713043",
