Settle across institutional boundaries, privately and atomically, between institutional and public ledgers, custody locations and venues without bridging or forfeiting custody.
Request a briefing →Tokenization aspired to rebuild an outdated system, but private ledgers created new private markets.
Citi Institute counts at least seventy two distributed or programmable ledgers in use across financial services, and calls them digital islands that are not inherently interoperable. Between any two of them, finance falls back on pre-funding the far side, delivering first and waiting, or routing through a firm that already reaches both and handing it the client.
Citi Institute, Tokenization 2030: Wall Street On-Chain, June 2026. Ledger count as of May 2025.
The KeyStone system provides permissioned, non-custodial, atomic settlement between two or more ledgers of every kind: public networks, institutional networks, consortium networks, and depository networks.
Counterparties choose the venue, the network and the terms without paying for that choice in settlement friction.
How a settlement happens →Quote against inventory held anywhere.
Best execution stops being limited to the venues you have onboarded.
Clients reach every market through you rather than around you.
Buyers reach your listings without onboarding to your venue first.
Capital stops sitting pre-funded across accounts you may not use.
Cross-venue settlement becomes a product you sell.
Add corridors without adding integrations.
Members settle against books that never had to join.
KeyStone never holds assets, matches trades, or bridges chains. It cannot compete with the providers it connects, which is what lets the system coordinate settlement between firms that cannot settle with each other.
A settlement carries what its own legs require and nothing else. No counterparty sees your book, your positions or the rest of your business, and neither does KeyStone.
Built by the operators of payments infrastructure that clears billions, engineered to the standard institutional regulators expect.
