Send a user operation ( Smart Contract )

spacelisk-js ships with a helper function that builds a transaction by encoding the function data.

import { AA, encodeContractData } from "spacelisk-js"

const pk = "0xprivate_key";
const api_key = "abcd1234";

const account = new AA(api_key, pk).account();

const contractData = encodeContractData({
        address: "0x22441385da0f1c4bd08073b322303ae496fbb35c",
        functionName: "transfer",
        abi: ContractABI,
        args: [
                "0xc80B282Cc68BF8ee6f70fEc96d1D9f7ab5dc3b3c", 
                parseEther("0.001")
        ]
 })

const data = await account.sendUserOp(contractData);

console.log("hash:", data.hash)

If you want to use a paymaster, you can pass the paymaster address as a second argument to sendUserOp.

const data = await account.sendUserOp(
    contractData,
    "0x596c1E3dE33C91c16ee96C7C3Ab7146b99f84717" // Paymaster address
);

console.log("hash:", data.hash)
