Monchain Check
Embed risk banners that stop drainers without breaking UX
Give every signer a transparent look at contract behavior, historical fraud, and safer alternatives before they approve a transaction.
High-risk contract
Known drain pattern detected. Funds routed through obfuscated proxy after approval.
Signals explained to your users
Malicious contract heuristics
Bytecode comparisons, honeypot signatures, proxy swaps, and gas griefing signals detected before signing.
User reputation & device
Device fingerprint drift, SIM swap intel, and behavior anomalies highlight likely account takeovers.
Contextual callouts
Plain-language explanations and severity badges show what changed since the last interaction.
End-to-end embed flow
1. Intent capture
Wallet collects transaction details and optional user statements; payload is hashed for privacy and sent to Monchain Check.
2. Risk banner injection
In under 450 ms, the SDK returns a score, severity band, and copy snippet you drop into your UI.
3. User decision
Present remediation options (cancel, continue, request support) without forcing the flow offline.
4. Escalation hooks
High-risk signatures can auto-open support chats, trigger device challenges, or file cases via webhook.
