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 Native 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).

Alchemy Account Kit provides modular smart accounts with built-in gas sponsorship via Alchemy’s Gas Manager. Create and manage smart accounts, submit gasless transactions, and execute batched UserOperations — all without requiring users to leave your application. Supports both EIP-4337 and EIP-7702 modes.

Setup

Create an Alchemy account and obtain your API key and Gas Policy ID from the Alchemy dashboard.
Install the required dependencies:

npm install @getpara/react-native-wallet @getpara/aa-alchemy viem

yarn add @getpara/react-native-wallet @getpara/aa-alchemy viem

pnpm add @getpara/react-native-wallet @getpara/aa-alchemy viem

Usage

useAlchemySmartAccount
createAlchemySmartAccount

The simplest way to integrate Alchemy smart accounts into your React Native application. The hook manages initialization, caching, and re-creation automatically via React Query.

AlchemySmartAccount.tsx

const GAS_POLICY_ID = process.env.EXPO_PUBLIC_ALCHEMY_GAS_POLICY_ID!;

export function AlchemySmartAccount() {
  // Initialize the smart account. The hook handles Para signer creation,
  // account client setup, and paymaster configuration internally.
  // It re-creates the account automatically if any config value changes.
  const { smartAccount, isLoading, error } = useAlchemySmartAccount({
    apiKey: ALCHEMY_API_KEY,
    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 {
    mutate: sendTransaction,
    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.
  const {
    mutate: sendBatch,
    isPending: isBatching,
    error: batchError,
  } = useMutation({
    mutationFn: async () => {
      if (!smartAccount) throw new Error("Smart account not ready");
      return smartAccount.sendBatchTransaction([
        { to: "0xRecipientA", value: parseEther("0.01") },
        { to: "0xRecipientB", data: "0xencodedCallData" },
      ]);
    },
    onSuccess: (receipt) => {
      console.log("Batch tx hash:", receipt.transactionHash);
    },
  });

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

  return (
    <View>
      <Text>Smart Account: {smartAccount.smartAccountAddress}</Text>
      <Text>Mode: {smartAccount.mode}</Text>
      <Button
        title={isSending ? "Sending..." : "Send Transaction"}

For use outside React components or when you need more control over initialization.

alchemy-action.ts

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

import { parseEther } from "viem";

// `para` is your authenticated Para instance
const smartAccount = await createAlchemySmartAccount({
  para,
  apiKey: "YOUR_ALCHEMY_API_KEY",
  chain: sepolia,
  gasPolicyId: "YOUR_GAS_POLICY_ID",
  mode: "4337", // or "7702"
});

if (smartAccount) {
  // Send a single transaction
  const receipt = await smartAccount.sendTransaction({
    to: "0xRecipient",
    value: parseEther("0.01"),

  // Send batched transactions
  const batchReceipt = await smartAccount.sendBatchTransaction([
    { 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 Alchemy Dashboard and pass the policy ID as gasPolicyId.

You can optionally pass bundlerUrl and paymasterUrl to use custom infrastructure instead of ZeroDev’s defaults. For more on managing your ZeroDev project and RPC endpoints, see the ZeroDev RPC documentation.

The Pimlico bundler/paymaster URL is automatically constructed from your API key and chain name. You can override it with a custom rpcUrl. Pimlico’s permissionless.js also supports other account types (Safe, Kernel, Biconomy, SimpleAccount) — see the permissionless.js tutorial.
