Portal’s Android SDK provides EVM Account Type management through the portal.evmAccountType API. This enables checking wallet account types 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
  • Upgrade to EIP-7702 to enable ejecting the Portal wallet’s EOA private key

​
Prerequisites

Before using EVM Account Type operations, ensure you have:

​
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. 
lifecycleScope.launch {
    try {
        val chainId = "eip155:10143" // Monad Testnet

        val status = portal.evmAccountType.getStatus(chainId)

        println("Status: ${status.data.status}")
        println("EOA Address: ${status.metadata.eoaAddress}")

        status.metadata.smartContractAddress?.let {
            println("Smart Contract Address: $it")
        }

        if (status.data.status == "EIP_155_EOA") {
            println("Can upgrade to EIP-7702")
        } else if (status.data.status == "EIP_7702_EOA") {
            println("Already upgraded")
        } else {
            println("Cannot upgrade")
        }
    } catch (e: Exception) {
        println("Failed to get account status: ${e.message}")
    }
}
Response (EvmAccountTypeResponse):
  • 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 (nullable, may be null for EOA-only accounts)
  • metadata.chainId: The chain identifier

​
Upgrading to EIP-7702

Use upgradeTo7702 to upgrade an EOA wallet to EIP-7702. This method automatically handles the entire upgrade process, including gas subsidization, and returns the transaction hash directly. 
lifecycleScope.launch {
    try {
        val chainId = "eip155:10143" // Monad Testnet

        // Upgrade to EIP-7702
        val txHash = portal.evmAccountType.upgradeTo7702(chainId)
        println("Upgrade done! TX: $txHash")

        // Verify final status
        val statusAfter = portal.evmAccountType.getStatus(chainId)
        println("Final Status: ${statusAfter.data.status}")

        if (statusAfter.data.status == "EIP_7702_EOA") {
            println("Successfully upgraded to EIP-7702!")
        }
    } catch (e: Exception) {
        println("Upgrade failed: ${e.message}")
    }
}
What happens during the upgrade:
  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
Response: The method returns a String containing the transaction hash of the submitted upgrade transaction.
The upgrade process is irreversible per wallet. Once upgraded to EIP-7702, the wallet cannot be reverted to a standard EOA on that chain.
