Overview

EIP-7702 is available as of [email protected] (web) and @magic-sdk/[email protected] / @magic-sdk/[email protected] (React Native).

EIP-7702 introduces a new transaction type (Type-4) that allows Externally Owned Accounts (EOAs) to temporarily delegate to smart contract code. This enables account abstraction features like batched transactions, gas sponsorship, and session keys for regular wallets. Magic supports EIP-7702 through two SDK methods:

wallet.sign7702Authorization() — Signs an authorization that delegates your EOA to a smart contract implementation
wallet.send7702Transaction() — Sends a Type-4 transaction that includes signed authorizations

Compatibility

EIP-7702 operates headlessly with no UI confirmation prompt
Requires a network that supports EIP-7702 (e.g., Ethereum Mainnet, Sepolia, Arbitrum, Base, Optimism)
The wallet must have ETH (or the network’s native token) to pay for gas

Use Cases

Temporarily delegate an EOA to a smart contract implementation for advanced features
Enable batched transactions through a delegated smart account
Integrate with account abstraction infrastructure that leverages EIP-7702

Usage

Step 1: Sign an EIP-7702 Authorization

The sign7702Authorization method signs an authorization that delegates your EOA to a specified smart contract. This authorization is then included in a Type-4 transaction.

JavaScript

import { Magic } from 'magic-sdk';

const magic = new Magic('YOUR_PUBLISHABLE_API_KEY', {
  network: {
    rpcUrl: 'https://eth-sepolia.g.alchemy.com/v2/YOUR_ALCHEMY_KEY',
    chainId: 11155111,
  },
});

// Sign an EIP-7702 authorization
const authorization = await magic.wallet.sign7702Authorization({
  contractAddress: '0x000000004F43C49e93C970E84001853a70923B03',
  chainId: 11155111,
});

console.log('Authorization:', authorization);
// {
//   contractAddress: '0x000000004F43C49e93C970E84001853a70923B03',
//   chainId: 11155111,
//   nonce: 0,
//   v: 27,
//   r: '0x...',
//   s: '0x...'
// }

Parameters

Parameter	Type	Required	Description
`contractAddress`	`string`	Yes	The smart contract implementation address to delegate to
`chainId`	`number`	Yes	The chain ID for the authorization
`nonce`	`number`	No	The account nonce. If omitted, fetched from the network automatically

Response

Field	Type	Description
`contractAddress`	`string`	The contract address that was authorized
`chainId`	`number`	The chain ID for the authorization
`nonce`	`number`	The nonce used in the authorization
`v`	`number`	The `v` component of the signature (27 or 28)
`r`	`string`	The `r` component of the signature
`s`	`string`	The `s` component of the signature

Step 2: Send a Type-4 Transaction

The send7702Transaction method sends a Type-4 transaction that includes the signed authorization list. This is what actually executes the delegation on-chain.

JavaScript

// Send a Type-4 transaction with the authorization from Step 1
const { transactionHash } = await magic.wallet.send7702Transaction({
  to: '0x1234567890123456789012345678901234567890',
  value: '0x0',
  data: '0x',
  authorizationList: [authorization],
});

console.log('Transaction hash:', transactionHash);

Parameters

Parameter	Type	Required	Description
`to`	`string`	Yes	The recipient address
`authorizationList`	`array`	Yes	Array of signed authorizations returned by `sign7702Authorization`
`value`	`string`	No	Value to send in wei (hex string). Defaults to `'0x0'`
`data`	`string`	No	Transaction calldata. Defaults to `'0x'`
`gas`	`string`	No	Gas limit (hex string). If omitted, estimated automatically
`gasLimit`	`string`	No	Alias for `gas`
`maxFeePerGas`	`string`	No	Max fee per gas (hex string). If omitted, fetched from the network
`maxPriorityFeePerGas`	`string`	No	Max priority fee per gas (hex string). If omitted, fetched from the network
`nonce`	`number`	No	Transaction nonce. If omitted, fetched from the network

Response

Field	Type	Description
`transactionHash`	`string`	The hash of the submitted transaction
