Upgrading to EIP-7702

Portal’s React Native SDK provides EVM Account Type management through the portal.evmAccountType API. This enables checking wallet account types, retrieving wallet addresses, and upgrading EOA wallets to EIP-7702 on supported EVM chains.

Overview

The EVM Account Type functionality allows you to:

Check wallet status to determine the current account type
Get wallet addresses to retrieve EOA and smart contract addresses
Upgrade to EIP-7702 to enable ejecting the Portal wallet’s EOA private key

Account Type Constants

The SDK provides the WalletAccountType enum for type-safe account type comparisons:

import { WalletAccountType } from '@portal-hq/core'

// Available account types:
WalletAccountType.EIP_155_EOA        // Standard Ethereum EOA
WalletAccountType.EIP_7702_EOA       // EIP-7702 upgraded EOA
WalletAccountType.SMART_CONTRACT     // Smart contract wallet

Prerequisites

Before using EVM Account Type operations, ensure you have:

A properly initialized Portal client
An active wallet on a supported network (see Create a wallet)
Understanding of EVM Account Type concepts
You fund the Upgrade Sponsor address with native tokens for the target chain in the Portal Dashboard

Checking Wallet Status

Use getStatus to check the current account type of your wallet. The response includes both the account status and metadata about the wallet addresses.

import { WalletAccountType } from '@portal-hq/core'

const handleGetStatus = async () => {
  try {
    const { data, metadata } = await portal.evmAccountType.getStatus({
      chain: 'eip155:10143', // Monad Testnet
    })

    // Use the WalletAccountType enum for type-safe comparisons
    if (data.status === WalletAccountType.EIP_155_EOA) {
      console.log('✅ Can upgrade to EIP-7702')
    } else if (data.status === WalletAccountType.EIP_7702_EOA) {
      console.log('ℹ️ Already upgraded')
    } else if (data.status === WalletAccountType.SMART_CONTRACT) {
      console.log('❌ Cannot upgrade - Smart contract wallet')
    }
  } catch (e) {
    console.error('Failed to get account status', e)
  }
}

Response (GetStatusResponse):

data.status: One of EIP_155_EOA, SMART_CONTRACT, or EIP_7702_EOA
metadata.eoaAddress: The EOA address associated with the wallet
metadata.smartContractAddress: Your smart contract wallet address (optional, may be null/undefined for EOA-only accounts)
metadata.chainId: The chain identifier

Getting Wallet Addresses

Use getAddresses to retrieve the EOA and smart contract addresses for your wallet on a specific chain. This method is useful when you only need the addresses without the full status information.

const handleGetAddresses = async () => {
  try {
    const addresses = await portal.evmAccountType.getAddresses({
      chain: 'eip155:10143', // Monad Testnet
    })
    
    console.log('EOA Address:', addresses.eoaAddress)
    console.log('Smart Contract Address:', addresses.smartContractAddress)
  } catch (e) {
    console.error('Failed to get addresses', e)
  }
}

Response (GetAddressesResponse):

eoaAddress: The EOA address associated with the wallet
smartContractAddress: Your smart contract wallet address (optional; may be null or undefined for EOA-only accounts)
