Monchain Check

Monchain Check defends web3 transaction surfaces across two delivery channels.

HTTP API

• Issue an auth token via /v1/auth/token.
• Submit fraud evaluation requests with /v1/missions.
• Poll verdicts via /v1/missions/{id} when webhooks are offline.

SDKs

• React, React Native, Flutter, and Swift clients mirror the HTTP schema.
• Ship the same mission payloads while staying native to the host runtime.

Start with this overview no matter which channel you choose.
