Account Abstraction Integrations

Account Abstraction

Account abstraction (AA) replaces traditional externally owned accounts (EOAs) with programmable smart contract accounts. This unlocks capabilities that EOAs alone cannot provide:

Gas sponsorship — let users transact without holding native tokens for gas fees
Batched transactions — bundle multiple operations into a single atomic transaction
Session keys — grant temporary, scoped permissions without exposing the primary key
Custom authorization — implement multi-factor auth, spending limits, or recovery logic at the account level
Programmable accounts — create accounts with built-in rules for corporate or multi-user scenarios

Two standards are currently in use for AA on EVM-based chains:

	EIP-4337	EIP-7702
How it works	UserOperations processed by bundlers via an EntryPoint contract	EOA delegates to a smart contract via a type-4 transaction
Account address	New smart contract address (different from EOA)	Same as your EOA
Chain support	All EVM chains	Requires chain-level support
Infrastructure	Bundler + Paymaster	Provider-dependent
Gas overhead	Higher (extra validation steps)	Lower (native execution)
Maturity	Production-ready	Emerging
Best for	Maximum compatibility, dedicated smart wallet	Keeping EOA address, simpler flows

Both standards support gas sponsorship and batched transactions.

Learn more about EIP-4337 and EIP-7702 on the Ethereum Improvement Proposals site.

Para Integrations

Para acts as the signer (EOA) that controls smart contract wallets — it is not a smart wallet itself. Para handles secure key management via MPC, while the AA provider deploys and manages the smart contract account on-chain. This means your users’ private keys remain secure and under their control regardless of which provider you choose. Para wraps each provider in a shared SmartAccount interface. Whether you use EIP-4337 or EIP-7702 mode, your application code stays the same — you can swap providers or switch between standards without rewriting transaction logic. Every provider integration is available as an action function (createXxxSmartAccount) — an imperative async function you can call anywhere, including outside React components, inside custom hooks, or in server-side code. React applications also get a hook (useXxxSmartAccount) — a declarative wrapper powered by React Query that handles initialization, caching, and automatic re-creation when config changes. Both return the same SmartAccount object:

import type { Chain, Hex, LocalAccount, TransactionReceipt } from "viem";

interface SmartAccount {
  smartAccountAddress: Hex;              // On-chain account address
  signer: LocalAccount;                 // Para viem signer
  chain: Chain;                          // Configured chain
  mode: "4337" | "7702";                // Account type
  provider: string;                      // Provider name

  // Send a single transaction and wait for receipt
  sendTransaction(params: {
    to: Hex;
    value?: bigint;
    data?: Hex;
  }): Promise<TransactionReceipt>;

  // Send batched transactions atomically
  sendBatchTransaction(calls: Array<{
    to: Hex;
    value?: bigint;
    data?: Hex;
  }>): Promise<TransactionReceipt>;

  client: any;                           // Provider-specific client for advanced usage
}

When using mode: "7702", the return type narrows to include an optional delegationAddress field — the smart contract the EOA delegates to. When using mode: "4337", smartAccountAddress is the counterfactual smart contract address (different from signer.address).

Using with External Wallets

If your user signs in with a supported browser wallet (MetaMask, Rainbow, etc.) and has no embedded wallets in their session, invoking any of the hooks and not specifying an address (or specifying the external wallet’s address) will use that wallet as the smart account signer, with no extra configuration needed.

External wallets can only use EIP-4337 mode. EIP-7702 requires signAuthorization, which most browser wallets currently don’t support — attempting it throws a SmartAccountError with code INVALID_CONFIG.
The external wallet must be on the same chain as the smart account before calling sendTransaction. A mismatch throws a SmartAccountError with code CHAIN_MISMATCH. You can use wagmi’s useSwitchChain to manage your connection state before attempting a transaction.

  // account client setup, and paymaster configuration internally.
  // It re-creates the account automatically if any config value changes.
  const { smartAccount, isLoading, error } = useAlchemySmartAccount({

    chain: sepolia,
    gasPolicyId: GAS_POLICY_ID, // enables gas sponsorship
    mode: "4337", // or "7702" — see EIP comparison above
  });

  // Wrap sendTransaction in a mutation for loading/error state management.
  const {

    isPending: isSending,
    error: sendError,
  } = useMutation({
    mutationFn: async () => {
      if (!smartAccount) throw new Error("Smart account not ready");
      return smartAccount.sendTransaction({
        to: "0xRecipient",
        value: parseEther("0.01"),
      });
    },
    onSuccess: (receipt) => {
      console.log("Transaction hash:", receipt.transactionHash);
    },

  // Wrap sendBatchTransaction for executing multiple calls atomically.
  // All calls are bundled into a single on-chain transaction.

      ]);
    },
    onSuccess: (receipt) => {
      console.log("Batch tx hash:", receipt.transactionHash);
    },
  });

  if (isLoading) return <p>Setting up smart account...</p>;
  if (error) return <p>Error: {error.message}</p>;
  if (!smartAccount) return null;

  return (
    <div>
      <p>Smart Account: {smartAccount.smartAccountAddress}</p>
      <p>Mode: {smartAccount.mode}</p>

      {/* Single transaction */}
      <button onClick={() => sendTransaction()} disabled={isSending}>
        {isSending ? "Sending..." : "Send Transaction"}
      </button>

    </div>
  );
}

alchemy-action.ts

import { createAlchemySmartAccount } from "@getpara/aa-alchemy";

import { parseEther } from "viem";

// `para` is your authenticated Para instance
const smartAccount = await createAlchemySmartAccount({
  para,

if (smartAccount) {
  // Send a single transaction
  const receipt = await smartAccount.sendTransaction({

    { to: "0xRecipientA", value: parseEther("0.01") },
    { to: "0xRecipientB", data: "0xencodedCallData" },

}

Alchemy requires chains from @account-kit/infra (e.g. sepolia, baseSepolia). Plain viem chains are automatically mapped if an Alchemy equivalent exists. For gasless transactions, set up a Gas Manager Policy in your and pass the policy ID as gasPolicyId.

External wallet support: Alchemy supports external wallets (e.g. MetaMask, Rainbow) as signers via the signer parameter in 4337 mode. Requesting mode: "7702" with an external wallet will throw a SmartAccountError — external wallets cannot produce the raw signAuthorization needed for EIP-7702.

Set sponsorGas: false to disable gas sponsorship. In EIP-4337 mode, you can optionally provide factoryAddress and accountAddress for custom smart wallet deployments.

External wallet support: Thirdweb supports external wallets (e.g. MetaMask, Rainbow) as signers via the signer parameter in 4337 mode. Requesting mode: "7702" with an external wallet will throw a SmartAccountError — external wallets cannot produce the raw signAuthorization needed for EIP-7702.

provides native EIP-7702 smart accounts with built-in gas sponsorship via relay infrastructure.

Gelato only supports EIP-7702 mode. Gas sponsorship is built into Gelato’s relay infrastructure — no separate paymaster configuration is needed.

No external wallet support. Gelato is 7702-only and requires signAuthorization, which external wallets (MetaMask, Rainbow, etc.) cannot produce. Passing an external wallet as signer will throw a SmartAccountError.

provides 7702-native smart accounts with a built-in relay — no bundler or paymaster needed.

Setup

No API key or third-party account is needed. Porto uses its own relay RPC.
Gas sponsorship: On testnets, Porto’s relay sponsors gas by default — no setup needed. For mainnet, you must set up a to cover gas fees for your users. Run pnpx porto onboard --admin-key to create a merchant account, deploy a server-side merchant route using porto/server, and pass your endpoint URL as merchantUrl in the config below.

CDP only supports EIP-4337 mode and is limited to Base and Base Sepolia chains. No additional bundler packages are needed — CDP uses viem’s built-in toCoinbaseSmartAccount.

No external wallet support. CDP’s Coinbase smart wallet uses raw ecrecover for signature verification, which is incompatible with the EIP-191 prefix that external wallets (MetaMask, Rainbow, etc.) add when signing. Passing an external wallet as signer will throw a SmartAccountError.
