Regulatory

Compliance Framework

Every layer of the Plume stack is designed around regulatory compliance. From onchain KYC/AML hooks to automated market surveillance, Kimber embeds compliance directly into the protocol layer rather than treating it as an afterthought.

FINRA Rule 5310 — Best Execution

Kimber's smart order routing engine performs real-time best execution analysis for every customer order. The system evaluates price, speed, likelihood of execution, and total costs across all compatible venues.

  • Multi-venue price comparison for every order
  • Execution quality statistics maintained and reviewed
  • Regular and rigorous review of execution quality
  • Documentation of routing decisions for audit

FINRA Rule 3110 — Supervision

Risk-based supervisory procedures leverage onchain transparency for enhanced monitoring. Automated surveillance systems detect potential market abuse in real-time, with escalation procedures for suspicious activity.

  • Onchain market abuse detection models
  • Automated alert generation and escalation
  • Written supervisory procedures (WSPs)
  • Annual supervisory system review and update

  • Quarterly public disclosure reports
  • Venue-by-venue routing statistics
  • Payment for order flow disclosures
  • Material aspects of routing relationships

17 CFR § 242.302 — Recordkeeping
