​

Overview

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

​

Prerequisites

• 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

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

    if (data.status === 'EIP_155_EOA') {
      console.log('✅ Can upgrade to EIP-7702')
    } else if (data.status === 'EIP_7702_EOA') {
      console.log('ℹ️ Already upgraded')
    } else {
      console.log('❌ Cannot upgrade')
    }
  } catch (e) {
    console.error('Failed to get account status', e)
  }
}

• 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 EOA and Smart Contract Addresses

const handleGetAddresses = async () => {
  try {
    const result = await portal.evmAccountType.getAddresses({
      chain: 'eip155:10143', // Monad Testnet, or eip155:1 for mainnet
    })

    console.log('EOA address:', result.eoaAddress)
    console.log('Smart contract address:', result.smartContractAddress)
  } catch (e) {
    console.error('Failed to get addresses', e)
  }
}

• eoaAddress: The EOA address for the wallet on this chain
• smartContractAddress: The smart contract wallet address (if any)

​

Upgrading to EIP-7702

const handleUpgradeTo7702 = async () => {
  try {
    const txHash = await portal.evmAccountType.upgradeTo7702({
      chain: 'eip155:10143', // Monad Testnet
    })
    console.log('Upgrade submitted! TX hash:', txHash)

    const status = await portal.evmAccountType.getStatus({ chain: 'eip155:10143' })
    console.log('Final Status:', status.data.status)

    if (status.data.status === 'EIP_7702_EOA') {
      console.log('Successfully upgraded to EIP-7702!')
    }
  } catch (e) {
    console.error('Upgrade failed', e)
  }
}

1. Chain validation: Verifies the chain uses the eip155 namespace
2. Status check: Confirms the wallet is currently an EIP_155_EOA
3. Authorization building: Creates the EIP-7702 authorization list
4. Signature: Signs the authorization hash with your wallet
5. Transaction submission: Submits the subsidized upgrade transaction (gas is paid by Portal)
6. Transaction hash: Returns the on-chain transaction hash

​

Supported Networks
