📰 Understanding createUserOp

• createUserOp will construct and return a UserOperation object and hash using a transaction or collection of transactions, alongside smart account and fee payment information. It takes:
  • Account config object:
    • name - string, either BICONOMY, CYBERCONNECT, or SIMPLE.
    • version - string, either 1.0.0 or 2.0.0.
    • ownerAddress - string.
    • biconomyApiKey - (optional, for using Biconomy's Paymaster), string.
  • Array of transactions:
    • Standard transaction object.
  • Optionally, a token feeQuote object, retrieved from getFeeQuotes, only used if you're paying the gas fee in an ERC-20 token.
  • Token paymaster address - (optional), string.
