writeContract

The AbstractClient includes a writeContract method that can be used to call functions on a smart contract using the connected Abstract Global Wallet.

Usage

import { useAbstractClient } from "@abstract-foundation/agw-react";
import { parseAbi } from "viem";

export default function WriteContract() {
  const { data: agwClient } = useAbstractClient();

  async function writeContract() {
    if (!agwClient) return;

    const transactionHash = await agwClient.writeContract({
      abi: parseAbi(["function mint(address,uint256) external"]), // Your contract ABI
      address: "0xC4822AbB9F05646A9Ce44EFa6dDcda0Bf45595AA",
      functionName: "mint",
      args: ["0x273B3527BF5b607dE86F504fED49e1582dD2a1C6", BigInt(1)],
    });
  }
}

Parameters

Address

required

The address of the contract to write to.

Abi

required

The ABI of the contract to write to.

string

required

The name of the function to call on the contract.

unknown[]

The arguments to pass to the function.

Account

The account to use for the transaction. By default, this is set to the Abstract Global Wallet’s account.

Chain

The chain to use for the transaction. By default, this is set to the chain specified in the AbstractClient.

bigint

The amount of native token to send with the transaction (in wei).

Hex

Data to append to the end of the calldata. Useful for adding a “domain” tag.

bigint

The amount of gas to pay per byte of data on Ethereum.

Account | Address

Address of the paymaster smart contract that will pay the gas fees of the transaction.

Hex

Input data to the paymaster. Required if paymaster is provided.

Show Example with Paymaster

import { agwClient } from "./config";
import { parseAbi } from "viem";

const transactionHash = await agwClient.writeContract({
  abi: parseAbi(["function mint(address,uint256) external"]),
  address: "0xC4822AbB9F05646A9Ce44EFa6dDcda0Bf45595AA",
  functionName: "mint",
  args: ["0x273B3527BF5b607dE86F504fED49e1582dD2a1C6", BigInt(1)],
});

Returns

Returns a Promise<Hex> containing the transaction hash of the contract write operation.
