Upgrading to EIP-7702

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
Get wallet addresses to retrieve the EOA address and (if applicable) the smart contract address
Upgrade to EIP-7702 to enable ejecting the Portal wallet’s EOA private key

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.

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

Getting Wallet Addresses

Use getAddresses to retrieve the EOA and smart contract addresses for your wallet on a given chain. This is a convenience method that returns the EOA and optional smart contract address, equivalent to the address metadata returned by getStatus.

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

        val addresses = portal.evmAccountType.getAddresses(chainId)

        println("EOA Address: ${addresses.eoaAddress}")

        addresses.smartContractAddress?.let {
            println("Smart Contract Address: $it")
        }
    } catch (e: Exception) {
        println("Failed to get addresses: ${e.message}")
    }
}

Parameters:

chainId (String): A CAIP-2 chain identifier (e.g., "eip155:10143")

Response (EvmAccountTypeAddresses):

eoaAddress (String): The EOA address associated with the wallet
smartContractAddress (String?): The smart contract wallet address (nullable, null for EOA-only accounts)
