  • Invalid account address
  • user rejected request
  • message must be hex or string
| #### Integration with Web3 The `eth_sign` method enables developers to: * Sign transactions without broadcasting them * Deliver signed raw transactions to relayers {% tabs %} {% tab title="Ethers.js" %} ```javascript import { ethers } from "ethers"; const RPC_URL = "https://go.getblock.us/"; const provider = new ethers.JsonRpcProvider(RPC_URL); async function Call() { try { const result = await provider.send("eth_sign", [ "0x742d35Cc6634C0532925a3b844Bc454e4438f44e", "0x48656c6c6f20576f726c64" ]); console.log("The result:", result); return result; } catch (error) { console.error("The error:", error); throw error; } } ``` {% endtab %} {% endtabs %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
