Breaking API Change Migration Coordinator

WHAT IT DOES

This tool coordinates breaking API change migrations by analyzing contract versions, dependencies, and migration readiness status. It provides a comprehensive view of migration progress across multiple steps—from contract verification and API comparison to dependency mapping, testnet deployment, community communication, and mainnet migration. The tool analyzes both old and new contract versions, identifies breaking changes, maps dependent contracts and integrations, and tracks migration readiness. Results are presented as a detailed migration coordination report with step-by-step status indicators (ready/in_progress/pending), progress percentage, and detailed migration information. This is essential for teams executing breaking API changes, developers coordinating with integrators, and auditors ensuring migration readiness.

HOW TO USE

Connect your wallet (read-only, no transaction required) and select the target network. Enter the migration name, old contract address, new contract address, and set the lookback blocks for analysis. Click "coordinate migration" and the tool will verify both contracts, analyze their state and integration data, and generate a comprehensive migration coordination report. Results display a summary with migration details and progress percentage, detailed migration cards showing each step's status and supporting data, and a table of all migration steps with their statuses. Use the report to track migration progress, identify bottlenecks, and coordinate with your team and integrators.

TECHNICAL MECHANISM

The coordinator uses ethers.js v5.7.2 to perform a multi-stage migration analysis. First, it calls eth_getCode to verify both old and new contracts are deployed and uses block explorer APIs to fetch verification status, source code, and ABI for both versions. The tool then scans historical logs using eth_getLogs across the specified block range to identify usage patterns, upgrade events, and integration calls to the old contract. It analyzes the ABI differences between versions to identify breaking changes in function signatures, return types, and event definitions. The tool maps dependent contracts and integrations by analyzing transaction data and logs from the old contract. Each migration step is evaluated: contract verification (both contracts verified), API comparison (differences identified), dependency mapping (dependents found), migration scripts (development status), testnet deployment (validation status), community communication (announcement readiness), mainnet migration (deployment readiness), and post-migration monitoring (monitoring plan). Each step is assigned a status: ready (completed), in_progress (currently being worked on), or pending (not yet started). The overall progress percentage is calculated based on the number of completed and in-progress steps. Results are compiled into a structured report with detailed step information, status indicators, and migration progress metrics.

WHAT IT CANNOT SEE

This tool cannot actually execute migrations or modify contract state—it performs coordination and analysis only. It is limited by the RPC provider's rate limits and block range availability for historical log queries. It cannot predict user migration behavior or adoption rates—the tool provides a coordination view based on on-chain data and team input. The analysis relies on the accuracy and completeness of contract verification and event data; incomplete logs or unverified contracts may produce incomplete results. It cannot analyze contracts that are not verified or have opaque migration mechanisms where events are not emitted. The tool is limited to the specific contract instances and integration data that are accessible via RPC. It cannot guarantee that generated migration plans reflect actual migration timelines without manual review and stakeholder input—the tool provides a structured view based on available data, but the actual migration schedule depends on team coordination and integrator readiness.

PLEASE NOTE

This is a read‑only analytics tool—it never submits transactions or executes migrations. It is designed for EVM‑compatible chains and works best with verified contracts that emit upgrade and integration events. The migration coordination results are for informational and planning purposes only and should be reviewed by the project team. Always coordinate with your team, integrators, and stakeholders before executing breaking API changes. The tool's status indicators are heuristic and based on the available data—customize the migration plan as needed for your specific context and requirements.
