EIP Compatibility Matrix Generator for Target Chains

WHAT IT DOES

EIP Compatibility Matrix Generator for Target Chains analyzes smart contract bytecode and generates a comprehensive compatibility matrix showing which Ethereum Improvement Proposals (EIPs) are used by the contract and whether each target chain supports them. It retrieves on-chain contract bytecode via eth_getCode and fetches verified source code and ABI from block explorer APIs. The tool performs opcode-level scanning for EIP-specific opcodes and patterns, including EIP-1559 (fee market), EIP-3855 (PUSH0), EIP-1153 (transient storage), EIP-2929 (gas cost increases), EIP-2930 (access lists), EIP-3074 (AUTH/AUTHCALL), and others. It then cross-references detected EIP usage against a built-in database of network-specific EIP support status for Ethereum Mainnet, Optimism, BNB Chain, Gnosis, Polygon, Arbitrum, Base, and other EVM chains. The output includes a visual matrix with EIPs as rows and target chains as columns, with status indicators (supported, partial, unsupported, unknown), an overall compatibility score, a count of critical issues, and actionable recommendations for ensuring compatibility across all target deployment environments.

HOW TO USE

Connect your BGWallet to the target EVM chain. Paste the address of the contract you wish to analyze. Select the target chains you plan to deploy to using the chip selector—you can choose multiple chains to generate a comprehensive cross-chain matrix. Optionally supply a GitHub repository URL to pull compiler version information and EIP implementation notes for additional context. The tool fetches the contract's bytecode, performs opcode disassembly to detect EIP-specific patterns, and builds a compatibility matrix against the selected target chains. Review the visual matrix, the overall compatibility score, critical issues count, and the list of recommendations. Use the matrix to identify chains that may not support EIPs your contract relies on, and plan your deployment strategy accordingly—for example, by deploying to chains with full support first, or by refactoring your contract to avoid unsupported EIPs.

EIP DETECTION AND CROSS-CHAIN SUPPORT MAPPING ENGINE

The real technical mechanism is the EIP detection and cross-chain support mapping engine that combines opcode analysis with a curated database of network capabilities. The tool disassembles the deployed bytecode into its constituent opcodes and scans for opcodes and patterns associated with specific EIPs: PUSH0 (0x5F) for EIP-3855, TLOAD (0x5C) and TSTORE (0x5D) for EIP-1153, BASEFEE (0x48) for EIP-1559, and other EIP-specific patterns. For each detected EIP, the engine cross-references a built-in metadata database that tracks EIP support status across major EVM chains—Ethereum Mainnet supports most EIPs, while chains like BNB Chain and Gnosis may have partial or no support for newer EIPs such as EIP-3855 and EIP-1153. The database is versioned and can be updated as networks upgrade their EVM implementations. The tool also detects compiler version fingerprints from bytecode metadata (e.g., Solidity version embedded in the contract) to estimate which EIPs a contract is likely to use based on compiler defaults. The final output includes a weighted compatibility score—100% if all detected EIPs are fully supported on all target chains, with penalties for partial support and critical failures for unsupported EIPs. This approach provides developers with a clear, actionable view of cross-chain compatibility risks before deployment, preventing failures caused by EIP mismatches.

WHAT IT CANNOT SEE

This tool cannot generate a complete compatibility matrix without access to contract bytecode or source code. It is limited by your RPC provider's rate limits for bytecode retrieval, which may delay analysis on congested networks. It cannot determine if EIP-specific features are actually executed at runtime versus merely present in bytecode—some EIPs may be used only in unreachable code paths, but the tool flags them regardless. 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 obfuscated or indirect usages, such as EIP-specific features called via DELEGATECALL or through inline assembly that obscures the opcode. The tool cannot assess runtime behavior or performance implications of EIP compatibility, such as gas cost differences between chains that support an EIP differently. It may produce false positives for opcodes that appear in data sections rather than code, such as in constant data arrays or jump tables. The tool does not execute the contract to validate compatibility, so it cannot confirm whether EIP-specific operations would succeed or revert on each target chain. It cannot account for network-specific EIP activation status or future upgrade schedules—some chains may enable EIPs after the analysis is performed.

PLEASE NOTE

This tool works exclusively with EVM-compatible 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 modify or deploy any code—it only produces compatibility assessments. EIP support status varies by chain and may change with network upgrades. Always verify compatibility against official network documentation and test on target chains before production deployment.
