The Startale AA SDK supports Soneium Minato (testnet) and Soneium Mainnet. Both run EntryPoint v0.7 so the SDK call sites are identical across networks; only the chain object and bundler URL change.

What “EntryPoint v0.7” means for you

The EntryPoint contract is the onchain singleton that validates and executes UserOperations. Version v0.7 is the current spec; the practical implications are:
  • The SDK encodes UserOperations in the v0.7 layout (paymasterAndData is split into paymaster, paymasterVerificationGasLimit, and paymasterPostOpGasLimit).
  • The bundler accepts the eth_sendUserOperation JSON-RPC method with the v0.7 schema.
  • ERC-7579 module actions reference EntryPoint v0.7 selectors when building installation calldata.
You do not need to set the EntryPoint version manually; the SDK targets v0.7 throughout.

import { http, createPublicClient } from "viem"
import { soneium, soneiumMinato } from "viem/chains"
import { toStartaleSmartAccount } from "@startale-scs/aa-sdk"

const chain = process.env.NETWORK === "mainnet" ? soneium : soneiumMinato

const account = await toStartaleSmartAccount({
  signer,
