Using the full ERC20 or Native balance in a call

The Squid Multicall can update the value of a param on-chain before or after the Swap or bridge has occurred. This lets you do the following:

• Send the remainder of tokens to the user's address, after minting or buying something at a fixed price

• Stake the full amount received from a swap

• Unstake, then swap the full amount across chains

This is designated by using callType

export enum SquidCallType {
  DEFAULT = 0,
  FULL_TOKEN_BALANCE = 1,
  FULL_NATIVE_BALANCE = 2,
  COLLECT_TOKEN_BALANCE = 3, // unused in hooks
}

FULL_ERC20_BALANCE

const sendRemainderToUserCall = {
        callType: SquidCallType.FULL_TOKEN_BALANCE, // transfer any remaining MAGIC to the user's account
        target: magicToken,
        value: "0",
        callData: transferMagicEncodeData,
        payload: {
          tokenAddress: magicToken,
          inputPos: 1,
        },
        estimatedGas: "50000",
},
