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
Address
required

The address of the contract to write to.

​
abi
Abi
required

The ABI of the contract to write to.

​
functionName
string
required

The name of the function to call on the contract.

​
args
unknown[]

The arguments to pass to the function.

​
account
Account

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

​
chain
Chain

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

​
value
bigint

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

​
dataSuffix
Hex

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

​
gasPerPubdata
bigint

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

​
paymaster
Account | Address

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

​
paymasterInput
Hex

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

​
Returns

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