Compliance first

Compliance is not a report produced after settlement. It is the gate every settlement passes on the way in and the record it leaves on the way out.

A failed check never began.

Entity screening, wallet screening, jurisdiction, eligibility and your own limits are evaluated before any leg commits, on every side of the transaction. There is no such thing as remediation after the fact, because there is no fact until every check has passed.

Trusted infrastructure

The gate has two layers, entity screening and wallet screening, and both run on firms your compliance department already knows, so diligence on KeyStone is diligence on names it has already done. Valuation and messaging run on named infrastructure too, listed beneath, and neither is a layer of the gate.

The gate
Entity screening

LSEG World-Check

Sanctions, politically exposed persons and adverse media, screened on every party to a settlement before anything commits.

Wallet screening

CipherOwl

On-chain screening of the wallets on every leg: behavior, sanctions exposure and the history a ledger address carries with it.

Valuation and messaging
Valuation

Chainlink

The oracle path for valuation, recorded from a counterparty-agreed value today with the price feed in design, and cross-chain messaging between the books a settlement touches.

Cross-chain messaging

LayerZero

Messaging that carries commitments between ledgers, so every book hears the same instruction and no book hears a different one. What crosses is the instruction. The asset stays where it is.

Every settlement leaves the file your auditor asks for.

The bundle is constructed by the settlement itself. Each party receives its own, covering its own side, against one anchored proof they can all check.

Independent assurance is underway, and this page will state each certification plainly when it is issued, and not a day before. Production is planned for Q1 2027, conditional on two independent security audits.
