If you are using Particle Network to sign transactions, you can get the signer directly from the ParticleProvider.

Configuring Particle Network

Particle Network has its own account abstraction SDK that you can use with Stackup. Read more about it here: https://docs.particle.network/developers/account-abstraction

Integration

The core part of the integration is creating a ParticleProvider, from which you can get a signer.

import { ParticleNetwork } from '@particle-network/auth';  
import { SmartAccount } from '@particle-network/aa';  
import { ParticleProvider } from '@particle-network/provider';

const particle = new ParticleNetwork({...});  
const provider = new ethers.providers.Web3Provider(new ParticleProvider(particle.auth));

// Initialize the builder  
const signer = provider.getSigner();  
var builder = await Presets.Builder.SimpleAccount.init(signer, rpcUrl);  
const address = builder.getSender();  
console.log(Account address: ${address});
