Auth providers overview

The Startale AA SDK does not authenticate users itself. It accepts a signer and turns it into a smart account. Anything that produces a viem WalletClient, an EIP-1193 provider, a viem LocalAccount, or an ethers.Wallet qualifies as a signer, which means you can keep using whichever auth or wallet stack you already trust.

Source: StartaleGroup/scs-aa-sdk. For the full signer matrix, see Installation and setup.

Where the auth provider fits

The auth provider’s only job in this diagram is to produce the signer that goes into toStartaleSmartAccount. Everything downstream (bundler, paymaster, EntryPoint) is identical regardless of how the user logged in.

Pain point	What AA + social login fixes
Users do not have native ETH	Sponsor gas via the SCS paymaster, or charge a stable token.
Seed phrase friction	The auth provider derives keys from the social login; the smart account address is counterfactual.
Lost access	Use Social recovery so a guardian set can rotate the signer.
Repeated signature prompts	Issue a Smart Session so scoped actions skip the prompt.

First-party integrations

Dynamic

Embedded wallets, social and email login, MPC and WebAuthn key custody. Exposes a viem WalletClient directly.

Privy

Email, OAuth, and external wallet login. Exposes an EIP-1193 provider you can wrap with createWalletClient.

Bring your own provider

Any provider that exposes one of the four signer shapes will work. The integration shape is always:

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

const account = await toStartaleSmartAccount({
  signer,                     // from your auth provider
  chain: soneiumMinato,
  transport: http(),
  index: 0n,
})

If your auth provider only gives you an EIP-1193 provider, wrap it with viem before passing it in:

import { createWalletClient, custom } from "viem"
import { soneiumMinato } from "viem/chains"

const signer = createWalletClient({
  account: connectedAddress as `0x${string}`,
  chain: soneiumMinato,
  transport: custom(provider), // any EIP-1193 provider
})

Symbol	Source	Role
`createWalletClient` / `custom`	`viem`	Wrap an EIP-1193 provider as a viem `WalletClient`.
`soneiumMinato`	`viem/chains`	Soneium Minato chain definition.
`toStartaleSmartAccount`	`@startale-scs/aa-sdk`	Build the modular smart account from the signer.
