Submitting a contract transaction request

This method allows you to send a contract transaction request.

To use this method, you must provide the transaction data. Here's an example: (we are approving 0.1 BUSD)

const spenderAddress = "0x78867BbEeF44f2326bF8DDd1941a4439382EF2A7";
const contractAddress = "0x78867BbEeF44f2326bF8DDd1941a4439382EF2A7";
const abi = [
  {
    inputs: [
      { internalType: "address", name: "spender", type: "address" },
      { internalType: "uint256", name: "amount", type: "uint256" },
    ],
    name: "approve",
    outputs: [{ internalType: "bool", name: "", type: "bool" }],
    stateMutability: "nonpayable",
    type: "function",
  },
];
const contract = new ethers.Contract(contractAddress, abi);
const DATA = contract.interface.encodeFunctionData("approve", [
  spenderAddress,
  "100000000000000000",
]);

Usage in your script

const sendContractTransaction = await alturaGuard.sendContractTransaction(CONTRACT_ADDRESS,CHAIN_ID,DATA);
const sendContractTransaction:any = await alturaGuard.sendContractTransaction(CONTRACT_ADDRESS,CHAIN_ID,DATA);

We utilize the ethers library to encode the data. You can learn more about it by referring to the following link:
