Ramp contracts, left unguarded, invite spam. Spam eats resources, corrupts data, and destroys trust. Once it starts, it spreads. The fix is not a single filter or rule — it’s a living Anti-Spam Policy built into how ramp contracts run, scale, and expire.
An Anti-Spam Policy for ramp contracts must enforce protection at every layer. Watch the entry points. Limit message rates. Verify sender identity. Track abuse patterns in real time. Block. Quarantine. Purge fast. Anything slower is too late.
Rate limiting is your first weapon. It stops sudden floods before they hit storage or processing layers. Link each identity to a clean rate profile. If an account exceeds safe patterns, throttle without hesitation. Always log violations and act on them.
Validation stops poisoned inputs. Enforce strict schema checks on every request. Use cryptographic signatures where possible. Never trust data that hasn't passed a deterministic validation process. Ensure that every ramp contract can reject spam at the function call itself.
