What KeyStone does
KeyStone coordinates multilateral atomic settlement between institutions across platforms and chains. One integration, every counterparty. Trades are agreed upstream - on execution venues or directly between counterparties. The terms then reach KeyStone by one of two routes: each counterparty submits its own side via the REST API and KeyStone pairs them, or one call carries every party and obligation at once. KeyStone runs compliance and creates the settlement on-chain. From there, smart contracts handle everything autonomously - deposits, atomic execution, and finalization. KeyStone compares the two submitted sides on instrument, direction and quantity, and refuses to create a settlement if they disagree. It does not bring together buying and selling interests: the counterparties have already selected each other and both present a shared trade reference before any comparison happens. KeyStone does not price, net, allocate, or take custody.- Atomic DvP - Delivery vs. Payment: every leg of a trade settles in one transaction, or none does. No partial execution.
- Cross-platform - Platform A’s seller and Platform B’s buyer in a single atomic settlement.
- Cross-chain - Asset on one chain, cash on another, with the assets never bridging. Each leg is escrowed and paid out on its own chain; the KeystoneRouter collects a funding confirmation from every chain involved and relays one release-or-abort decision back to each. Only a decision crosses the chain boundary, never value.
- Autonomous post-compliance - After compliance clears, contracts handle deposits, execution, and finalization.
- No custody - KeyStone never holds funds. Escrow recipients are bound at registration; no role, including KeyStone’s own admin, can redirect them.
