Bridge Adapter Compatibility Test Suite

WHAT IT DOES

This tool tests bridge adapter compatibility by analyzing adapter contract patterns, interface implementations, and configuration mappings. It performs a comprehensive suite of read-only checks against an adapter contract to verify that it correctly implements the interface for the target bridge (Axelar, LayerZero, Hyperlane, Wormhole, Chainlink CCIP, or Custom). The tool checks for contract deployment verification, wallet connectivity, adapter configuration validation, event emission patterns, and bridge-specific interface compatibility. Results are presented as a detailed test report with pass/fail/warn statuses for each test, along with bridge-specific recommendations. This is essential for developers building cross-chain adapters, auditors verifying adapter correctness, and teams ensuring adapter compatibility across different bridge implementations.

HOW TO USE

Connect your wallet (read-only, no transaction required) and select the target network. Enter the adapter name and contract address, select the target bridge type (Axelar, LayerZero, Hyperlane, Wormhole, Chainlink CCIP, or Custom), optionally specify the target bridge contract address, and set the lookback blocks for adapter analysis. Click "run compatibility tests" and the tool will verify the adapter contract, analyze its bytecode and ABI for bridge-specific patterns, check wallet connectivity, and run a comprehensive test suite tailored to the selected bridge type. Results display a summary with pass/fail/warn counts and an overall status, detailed test cards showing each test's outcome with supporting data, and a table of all tests. Use the report to identify adapter integration gaps, verify bridge compatibility, and ensure your adapter's interface aligns with the target bridge specification.

TECHNICAL MECHANISM

The analyzer uses ethers.js v5.7.2 to perform a multi-stage adapter compatibility test. First, it calls eth_getCode to verify the adapter contract is deployed and uses block explorer APIs to fetch verification status and source code. The tool then reads the current wallet state via BGWallet for context. It analyzes the adapter contract bytecode and ABI to detect bridge-specific interface patterns—looking for function signatures matching the target bridge interface (e.g., sendMessage, executeMessage for Axelar; lzSend, lzReceive for LayerZero; sendMessage, handle for Hyperlane; parseVA, verifyVA for Wormhole; ccipSend, ccipReceive for Chainlink CCIP). The tool also scans historical logs using eth_getLogs across the specified block range to identify adapter interaction events and usage patterns. Additionally, it checks for configuration mappings that link the adapter to the target bridge contract, verifying that the adapter has the necessary address and parameter configurations. Each test in the suite evaluates a specific aspect of adapter compatibility: contract deployment, wallet connectivity, adapter configuration (mappings and settings), event emission (adapter events for operations), and bridge-specific interface tests (correct function signatures and call patterns). Results are compiled into a structured report with detailed diagnostic information and bridge-type-specific recommendations based on the selected bridge standard.

WHAT IT CANNOT SEE

This tool cannot actually test adapter compatibility with all bridge implementations—it performs analysis of on-chain adapter patterns only. It is limited by the RPC provider's rate limits and block range availability for historical log queries. It cannot test adapter behavior with bridges that are not deployed or accessible on the current chain. The analysis relies on the accuracy and completeness of contract verification and adapter configuration data; unverified adapters or incomplete ABIs may produce incomplete results. It cannot analyze adapters that are not verified or have opaque implementation details where the bridge interface is not clearly distinguishable. The tool cannot test adapters for bridges that use off-chain or cross-chain state not reflected on-chain in a way that is accessible via read-only calls. It is limited to the specific adapter and bridge contracts that are accessible via RPC. It cannot guarantee adapter compatibility without manual review and integration testing across all target bridges, especially for edge cases or bridge-specific features that are not captured in the bytecode analysis.

PLEASE NOTE

This is a read‑only analytics tool—it never submits transactions or modifies adapters. It is designed for EVM‑compatible chains and works best with verified adapter contracts. The compatibility test results are for informational and audit purposes only and should not be considered a comprehensive integration test. Always manually verify adapter compatibility and perform actual cross-chain integration tests before deploying adapters to production. The tool's pattern detection is heuristic and may miss custom adapter implementations or bridge-specific features. Select the correct bridge type for accurate test results.
