# Supported networks

> Soneium chain identifiers, EntryPoint version, and ERC-20 tokens accepted by the Startale Token Paymaster.

The Startale AA SDK supports Soneium Minato (testnet) and Soneium Mainnet. Both run [EntryPoint v0.7](https://eips.ethereum.org/EIPS/eip-4337#entrypoint-contract) so the SDK call sites are identical across networks; only the chain object and bundler URL change.

## Soneium Minato (testnet)

## 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.

## Token paymaster supported tokens

The Startale Token Paymaster accepts the tokens below as gas. Pass the token address as `paymasterContext.token` in [`createSmartAccountClient`](/aa-sdk/tutorials/erc20-payment).

### Soneium Minato

The list above is updated whenever a new token is whitelisted; verify the latest addresses against the [SCS Portal](https://scs.startale.com) before shipping.

## Network selection in code

```ts theme={null}
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,
  chain,
  transport: http(),
  index: 0n,
})
```

| Symbol                     | Source        | Role                                                                                      |
| -------------------------- | ------------- | ----------------------------------------------------------------------------------------- |
| `soneium`, `soneiumMinato` | `viem/chains` | Pre-baked viem `Chain` definitions. Use them anywhere the SDK or `viem` asks for a chain. |
| `http`                     | `viem`        | HTTP transport. Defaults to the chain's public RPC unless you pass an override.           |
