FAQ

How do FX Reference Rates differ from crypto price feeds?

FX Reference Rates are formally governed benchmarks produced under a defined, auditable methodology in line with the IOSCO Principles, designed specifically for settlement, valuation, and institutional product issuance. Kaiko’s FX Reference Rates meet critical regulatory requirements for use in derivatives contracts, structured products, and on-chain financial applications. Crypto price feeds, by contrast, aggregate raw trade and order book data across exchanges without the same governance framework or regulatory oversight. For institutions requiring a legally defensible, independently administered price reference for foreign exchange, Kaiko FX Reference Rates provide the compliance foundation that a standard crypto price feed cannot.

How do on-chain FX rates perform compared to traditional daily FX fixes? 

Traditional FX fixes such as the London 16:00 or New York 10:00 cuts are point-in-time snapshots, leaving financial products exposed to intraday price moves between fixing windows. Kaiko’s FX reference rates publish continuously, providing a real-time, always-on alternative that eliminates the gaps between fixes. This makes them particularly suited to 24/7 on-chain applications and derivatives products that require continuous price discovery.

How are Kaiko’s FX rates delivered on-chain?

Kaiko on-chain FX rates are delivered 24/7 via the Kaiko Data On-Ramp, a purpose-built oracle infrastructure developed for regulated financial market participants. Available on the Canton Network, rates are published directly to smart contracts with free hourly prices available by default, and higher-frequency updates available on request. Kaiko’s blockchain-agnostic approach means FX rates can be delivered to any blockchain network, not just Canton.

How can I access Kaiko’s FX reference rates? 

Kaiko FX reference rates are available via two delivery methods. API access (available 24/5) enables direct integration into trading systems, risk models, and financial products. Oracle delivery brings rates on-chain via the Kaiko Data On-Ramp, supporting settlement, collateral marking, and NAV calculations on distributed ledger infrastructure. Historical rate data is available from January 2016 to support backtesting, model calibration, and audit requirements.
