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.
