What KeyStone does
KeyStone coordinates bilateral atomic settlement between institutions on different platforms and chains. One integration, every counterparty, any chain. Both counterparties submit settlement instructions independently via KeyStone’s REST API. KeyStone matches the instructions, runs compliance, and creates a settlement on-chain. From there, smart contracts handle everything autonomously - deposits, atomic execution, and finalization.- Bilateral atomic DvP - Delivery vs. Payment: both sides of a trade (the asset delivery and the payment) settle simultaneously, or neither does. No partial execution.
- Cross-platform - Platform A’s seller and Platform B’s buyer in a single atomic settlement.
- Cross-chain - Bond on Ethereum, USDC on Avalanche. Assets never bridge. LayerZero coordinates.
- Autonomous post-compliance - After compliance clears, contracts handle deposits, execution, and finalization.
- No custody - KeyStone never holds funds. Escrow contracts have no admin keys.
