sa_erc20_transfer

Create and submit an ERC20 token transfer transaction using user operation. The result is a user operation hash. You can check the success of the returned user operation hash through sc_getUserOpReceipt.

Because it is processed as a user operation, it is processed even if neither the owner nor the sender have a balance in the network's main coin (e.g. Ether, BNB) for gas fees. The gas fee will be paid on your behalf from your predefined payment master account.

Parameters

Name	Type	Description
contractAddress	String	Token contract address
owner	String	Owner address of smart account
sender	String	Sender address (Must be a smart account)
toAddress	String	To address
amount	BigDecimal	Amount of transfer
gasPrice	BigDecimal	Gas price
tempKey	String	tempKey for “transfer”
hashKey	String	hash(tempKey | secretKey)
signature	String	sign ( hash ( contractAddress | owner | sender | toAddress | amount | tempKey | hashKey ) ) by owner’s privateKey using signData API

Return Value

Name	Type	Description
userOpHash	String	User Operation Hash

Example

{
  "resultCode":"200",
  "resultMessage":"success",
  "resultData":{
    "userOpHash":"0xdba638a19c23ee0f69fb9e8683528531211d1a9deb8c93402c9294b170080415"
