Intent Expiry Handling Test Tool

WHAT IT DOES

Intent Expiry Handling Test Tool provides comprehensive testing for intent expiry mechanisms in intent-based protocols, enabling protocol developers, dApp developers, and DeFi participants to verify that intents correctly expire and are handled appropriately. It retrieves on-chain intent contract bytecode via eth_getCode and fetches verified source code and ABI from block explorer APIs. The tool analyzes intent expiry parameters including timestamps, block numbers, and duration settings, examines intent state and lifecycle data, and validates the expiry handling logic. It runs a suite of expiry tests including intent existence verification, expiry timestamp validation, expiry block number validation, duration-based expiry checking, expiry state transition verification, and expiry handling gas cost estimation. The output includes an expiry status (Active, Expired, or Pending), time remaining, expiry validation status, a detailed check matrix showing each validation check's result, and actionable recommendations for resolving issues—such as missing expiry parameters, incorrect timestamp configuration, or inefficient expiry handling gas costs. This enables protocol developers to ensure that intents correctly expire, that expired intents are properly cleaned up or rejected, and that users are not able to interact with expired intents.

HOW TO USE

Connect your BGWallet to the target EVM chain. Paste the address of the intent contract you wish to test. Provide the intent ID you want to check and the expiry parameters as a JSON object containing timestamp, block number, and/or duration. Optionally supply a GitHub repository URL to pull intent protocol implementation details and expiry specifications for additional context. The tool fetches the intent contract's bytecode and state, analyzes the expiry configuration, and runs a comprehensive expiry handling test suite. Review the expiry status, time remaining, expiry validation, check matrix, and recommendations. Use the results to verify that intents correctly expire and that expiry handling logic is properly implemented.

INTENT EXPIRY VALIDATION AND LIFECYCLE ANALYSIS ENGINE

The real technical mechanism is the intent expiry validation and lifecycle analysis engine that combines intent contract bytecode analysis with expiry semantics. The tool first retrieves the intent contract's bytecode and analyzes the intent lifecycle—identifying key functions such as createIntent, fulfillIntent, cancelIntent, and checkExpiry that handle intent creation, fulfillment, and expiry. It then parses the expiry parameters from the intent state, extracting the timestamp, block number, and duration settings that define when the intent expires. The engine validates that the expiry timestamp and block number are correctly set and consistent with the current chain state, checking that the expiry logic correctly rejects expired intents and accepts active ones. The duration-based expiry check verifies that intents with a duration parameter correctly compute their expiry time based on the creation time plus duration. The expiry state transition check ensures that intents correctly transition from active to expired state and that any associated funds are properly handled (e.g., returned to the creator or made available for refunds). The gas cost estimation helps developers understand the cost of expiry handling operations, enabling optimization of expiry logic. This approach provides developers with a comprehensive, automated way to test intent expiry handling, catching issues that would otherwise only surface during live operations and preventing users from interacting with expired intents or losing funds due to incorrect expiry logic.

WHAT IT CANNOT SEE

This tool cannot generate a complete intent expiry handling test without access to intent contract bytecode or expiry data. It is limited by your RPC provider's rate limits for data retrieval, which may delay analysis on congested networks. It cannot determine if intent expiry is correctly handled without executing the expiry logic—static analysis provides insights but does 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 expiry logic, such as expiry logic hidden in libraries or via delegate calls. The tool cannot assess runtime behavior or performance implications of expiry handling, such as how expiry logic behaves under different network conditions or gas price fluctuations. It may produce false positives for data that appears similar to expiry data but is used for other purposes. The tool does not execute the contract to validate expiry handling, so it cannot confirm that expired intents are correctly rejected or cleaned up. It cannot account for network-specific intent expiry implementation differences or future upgrades—different intent protocols may have different expiry mechanisms, time sources, or cleanup patterns. Intent expiry handling may vary across protocols and change over time as protocols evolve.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains that support intent-based protocols. 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 transactions—it only produces expiry assessments. Intent expiry is critical to protocol security and user protection; always verify expiry handling results against actual protocol behavior on testnet before mainnet deployment. Different intent protocols may have different expiry mechanisms, time sources, and cleanup procedures.
