Bytecode capabilities
PUSH-aware opcode and selector observations, including delegation, pause, freeze and mint patterns. Findings are not a reachability proof.

One integration issue.
A runnable fix.
Is a JavaScript/TypeScript API, SDK, MCP, or x402 integration failing? Start a free inquiry with a redacted error or public reproducer. After we confirm scope, the one-off Fix is $299 and includes a runnable patch, focused tests, and run instructions.
For one reproducible issue with unclear repair scope, the $49 Diagnostic provides a diagnosis and repair plan, with no patch. The $299 Growth plan is a separate 31-day API subscription.

SEPARATE BASE DEVELOPER API
One evidence layer. Three useful views.
Proxy & execution context
Resolve supported EIP-1967, UUPS, minimal-clone and beacon structures. Keep unresolved paths and trust limitations explicit.
Browse reference contracts →Sourced Base telemetry
Gas observations, tracked-token pool prices and large-transfer signals, with source and coverage information instead of whole-chain assumptions.
Explore the API sandbox →EVIDENCE, NOT A VERDICT
Understand the output before you act.
Static analysis does not establish contract safety or exploitability. M2M Sentinel never decides whether your application should transact.
4-Step Evidence-to-Policy Workflow
- Observed facts. Read the bytecode patterns, resolved targets and provenance returned by the API.
- Capability implication. Understand the pattern without assuming that a path is reachable.
- Consumer policy. Compare those observations with your application’s own constraints.
- Consumer action. Your application makes the review or execution decision, including how to handle unknown states.
Deterministic Reproducibility Metadata
Runtime and implementation hashes let you compare bytecode independently. Trust grading and limitations travel with the result.
FROM EXPLORING TO BUILDING
Start with one request.
This public sample calls the live Base USDC demo when you run it. Protected endpoints require an API key or x402 payment and fail closed if dependencies are unavailable.
