What is KeyStone OS?

KeyStone OS is a neutral settlement coordination layer for tokenized Real-World Assets (RWAs). Platforms integrate once via our API and gain access to atomic, compliant settlement across the entire network. We handle the hard parts: compliance screening, escrow coordination, state machine orchestration, and cross-platform settlement - so platforms can focus on their product.

How it works

1

Integrate

Connect your platform via M2M authentication and configure your settlement templates.
2

Instruct

Send a settlement instruction with parties, legs, and a template. KeyStone validates and begins orchestration.
3

Settle

KeyStone runs compliance checks, coordinates escrow deposits, and executes atomic settlement. Both platforms receive real-time webhook updates.

Key capabilities

  • Template-driven settlements - Define your settlement workflow once. The engine executes it deterministically.
  • Cross-platform settlement - Platform A’s seller, Platform B’s buyer. One atomic settlement.
  • Dual-layer compliance - Off-chain entity screening (LSEG World-Check) and on-chain wallet risk scoring (CipherOwl) at every settlement.
  • Smart contract escrow - Deposits are locked in escrow until all conditions are met. All-or-nothing execution.
  • Real-time webhooks - Every state transition is pushed to all involved platforms instantly.
  • Full audit trail - Every action, decision, and state change is recorded with cryptographic integrity.
