Circuit Compilation Artifact Validator

WHAT IT DOES

Circuit Compilation Artifact Validator provides comprehensive validation of ZK circuit compilation artifacts—including verification keys, proving keys, and Solidity verifier code—against on-chain verification contracts. It retrieves on-chain ZK verification contract bytecode via eth_getCode and fetches verified source code and ABI from block explorer APIs. The tool analyzes circuit compilation artifacts and metadata, including constraint counts, witness sizes, and public input structures, to ensure consistency and correctness. It validates that verification key parameters are correctly formatted and consistent with the on-chain verifier, that key pairs maintain cryptographic consistency, that public input structures align with the circuit's expected inputs, that constraint counts match the compiled circuit, that witness sizes are correct, and that the Solidity verifier code is compatible with the on-chain contract. The output includes an overall validation status (Valid, Invalid, or Partial), counts of artifacts checked and validation failures, a detailed artifact matrix showing each validation check's result, and actionable recommendations for addressing any issues—such as regenerating artifacts, verifying compilation logs, or updating the verifier contract. This enables ZK rollup operators, circuit developers, and auditors to ensure that compilation artifacts are correctly generated and consistent with on-chain verification logic before deploying to production.

HOW TO USE

Connect your BGWallet to the target EVM chain. Paste the address of the ZK verification contract that will be used to verify proofs from your circuit. Provide the verification key data in JSON format (including alpha, beta, gamma, and other Groth16 parameters). Optionally, provide artifact metadata such as constraint counts and witness sizes as a JSON string. Optionally supply a GitHub repository URL to pull circuit source code and compilation scripts for additional context. The tool fetches the verification contract's bytecode and state, analyzes the provided artifacts, and runs a comprehensive validation suite. Review the overall validation status, artifact matrix, and recommendations. Use the results to ensure that your compilation artifacts are correct and consistent with the on-chain verifier before deploying or using the circuit.

CIRCUIT ARTIFACT VALIDATION AND VERIFIER CONSISTENCY ENGINE

The real technical mechanism is the circuit artifact validation and verifier consistency engine that combines bytecode analysis with artifact metadata verification. The tool first extracts verification key parameters from the provided JSON data—including the verification key structure, public input definitions, and any circuit-specific metadata. It then analyzes the on-chain verification contract bytecode to identify the verification logic and expected key structure. The engine validates that the verification key format matches what the verifier contract expects, checking for compatibility with the proving system (e.g., Groth16, PLONK). It performs consistency checks to ensure that key pair components (alpha, beta, gamma, delta) are correctly paired and that the public input structure aligns with the circuit's expected input order and types. The tool also validates constraint counts and witness sizes against the circuit metadata, flagging mismatches that could indicate compilation errors or version mismatches. The Solidity verifier compatibility check ensures that the generated verifier code is compatible with the on-chain contract's ABI and function signatures. The validation engine produces a detailed report that identifies specific issues, enabling developers to pinpoint and fix problems in the compilation pipeline. This approach provides developers with a comprehensive, automated way to validate circuit compilation artifacts, catching issues that would otherwise only surface during proof verification failures and preventing deployment of incorrect or inconsistent artifacts.

WHAT IT CANNOT SEE

This tool cannot generate a complete artifact validation without access to verification contract bytecode or circuit artifacts. It is limited by your RPC provider's rate limits for data retrieval, which may delay analysis on congested networks. It cannot determine if compilation artifacts correctly correspond to the circuit source without executing verification—the tool validates consistency with the verifier contract but does not recompile the circuit from source. 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 compilation logic, such as verification logic hidden in libraries or via delegate calls. The tool cannot assess runtime behavior or performance implications of compiled artifacts, such as proof verification gas costs or proving time. It may produce false positives for data that appears similar to artifact data but is used for other purposes. The tool does not execute the contract to validate artifact correctness, so it cannot confirm that the artifacts would successfully verify a proof on-chain. It cannot account for network-specific compilation differences or future upgrades—different ZK protocols may use different compilation processes. Circuit compilation artifacts may vary across ZK protocols and compiler versions, making validation dependent on accurate metadata.

PLEASE NOTE

This tool works exclusively with EVM-compatible ZK rollup chains. 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 compilation or verification—it only produces validation assessments. Circuit compilation artifacts are critical to ZK system correctness; always validate artifacts against official compilation logs and test with actual proofs on testnet before mainnet deployment.
