signTransaction

The AbstractClient includes a signTransaction method that can be used to sign a transaction using the connected Abstract Global Wallet. Transactions are signed by the approved signer account (EOA) of the Abstract Global Wallet.

Usage

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

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

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

    const signature = await agwClient.signTransaction({
      to: "0x273B3527BF5b607dE86F504fED49e1582dD2a1C6",
      data: "0x69",
    });
  }
}
