Smart Account Factory Deployment Tester

WHAT IT DOES

Smart Account Factory Deployment Tester provides comprehensive testing for ERC-4337 smart account factory contracts, ensuring they correctly deploy smart accounts with the right parameters. It retrieves on-chain account factory contract bytecode via eth_getCode and fetches verified source code and ABI from block explorer APIs. The tool analyzes smart account deployment parameters and initialization data, validates wallet contract bytecode and creation code, and simulates the factory deployment process. It runs a suite of deployment checks including factory contract interface validation, deployment parameter validation, account creation code analysis, salt-based address calculation, initialization data validation, and deployment gas estimation. The output includes a deployment status (Success, Partial, or Failed), the predicted account address that would be created, estimated gas cost, a detailed check matrix showing each deployment check's result, and actionable recommendations for resolving issues—such as invalid deployment parameters, incorrect initialization data, or inefficient gas usage. This enables AA wallet developers, factory implementers, and dApp developers to verify that smart account factories correctly deploy accounts and to optimize deployment gas costs before production deployment.

HOW TO USE

Connect your BGWallet to the target EVM chain. Paste the address of the ERC-4337 account factory contract you wish to test. Provide the deployment parameters as a JSON object including owner address, salt, and initialization data. Optionally supply a GitHub repository URL to pull factory implementation details and deployment specifications for additional context. The tool fetches the factory contract's bytecode and state, analyzes the deployment parameters, and runs a comprehensive deployment test suite. Review the deployment status, predicted account address, estimated gas cost, check matrix, and recommendations. Use the results to verify that your factory correctly deploys smart accounts and to optimize deployment parameters for gas efficiency.

SMART ACCOUNT FACTORY DEPLOYMENT VALIDATION AND ADDRESS PREDICTION ENGINE

The real technical mechanism is the smart account factory deployment validation and address prediction engine that combines factory bytecode analysis with CREATE2 address calculation. The tool first retrieves the factory contract's bytecode and disassembles it to identify the deployment function—typically a createAccount function that accepts owner, salt, and initialization parameters. It then validates the deployment parameters against the expected format, checking that the owner address is valid, the salt is properly formatted, and the initialization data matches the account's expected constructor arguments. The engine calculates the predicted account address using CREATE2 semantics: address = keccak256(0xff ++ factoryAddress ++ salt ++ keccak256(accountCreationCode)). It validates that the account creation code matches the expected wallet contract bytecode, ensuring that the factory is deploying the correct account implementation. The tool also estimates the gas cost of the deployment by analyzing the factory's bytecode and accounting for the creation code size and initialization operations. The deployment checks cover the entire deployment lifecycle—from parameter validation to address calculation to gas estimation—ensuring that the factory is correctly configured and that deployments will succeed. This approach provides developers with a comprehensive, automated way to test smart account factory deployments, catching issues that would otherwise only surface during on-chain execution and preventing failed deployments or unexpected account addresses.

WHAT IT CANNOT SEE

This tool cannot generate a complete factory deployment test without access to factory contract bytecode or deployment parameters. It is limited by your RPC provider's rate limits for data retrieval, which may delay analysis on congested networks. It cannot determine if the factory correctly deploys smart accounts without executing deployment—address prediction and parameter validation are estimates and do not replace full execution. The detection relies on the completeness of the ABI and source code verification; unverified contracts or incomplete verification data will produce incomplete or inaccurate results. Detection is based on bytecode pattern matching and may miss indirect or obfuscated factory logic, such as deployment logic hidden in libraries or via delegate calls. The tool cannot assess runtime behavior or performance implications of deployment, such as how the factory handles edge cases or reverts under certain conditions. It may produce false positives for data that appears similar to factory deployment data but is used for other purposes. The tool does not execute the contract to validate deployment, so it cannot confirm that the factory successfully deploys accounts in all scenarios. It cannot account for network-specific factory implementation differences or future upgrades—different chains may have different factory implementations or modifications to ERC-4337. Factory deployment behavior may vary across implementations and ERC-4337 versions, making testing dependent on accurate metadata.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains that support ERC-4337 account abstraction. It requires active internet connectivity to access block explorer APIs and RPC endpoints. Some block explorers may require API keys for high-volume bytecode retrieval. The tool is read-only and does not execute any deployments—it only produces test assessments. Smart account factory deployment is critical to AA wallet creation; always verify test results against actual deployment behavior on testnet before mainnet deployment. Different factory implementations may have different deployment patterns and address calculation methods.
