Overview

Currently, Orcfax provides support for Current Exchange Rate (CER) type feeds. Integrators may review the full list of available cer-feeds; feed activity for mainnet and preview may be monitored through the Orcfax Explorer.

Current Exchange Rate feeds​

CER feeds publish statements relating to the current price of a given currency against another. Feeds of this type include ADA-USD and FACT-ADA.

For a feed of type CER, the naming convention is {{base-currency}}-{{quote-currency}}.

Examples:
  • crypto-fiat: ADA-USD
  • crypto-stable: ADA-iUSD
  • crypto and another native asset: FACT-ADA

The price values published by these feeds are derived from centralized exchange (CEX) data or decentralized exchange (DEX) data.

For CEX based feeds, fiat currency names follow ISO 4217 and ordering follows forex conventions where applicable. In all other cases, ordering defers to how pairs appear on the centralized or decentralized exchanges.

info

Additional details on the form of CER feeds, their published datum, and archived records depend on whether their data is sourced from a CEX or DEX; we have separated design documents for each respectively.

Subsidized feeds​

Orcfax may periodically identify feeds which it will commit to supporting through subsidized publication. These feeds will be designated as Subsidized on the Explorer, and are provided so developers have opportunities to design their solutions from the beginning with authentic and verifiable data as a foundation.

when an integrator activates a subscription for a feed which had previously published as a subsidized feed it will no longer be identified as such and will instead be labeled a sponsored feed.

Sunsetting subsidized feeds​

In contrast to showcase feeds, subsidized feeds can be used in production because Orcfax has agreed to cover the cost of their support.

While Orcfax has committed to maintaining access to these feeds, integrators who wish to utilize these feeds without a subscription should do so at their own risk; Orcfax still reserves the right to adjust or remove support for these feeds as business needs dictate. Changes to services relating to subsidized feeds will be announced three months in advance to provide integrators with adequate forewarning.

When an integrator agrees to financially support a given feed, it will be designated as a Sponsored feed on the Explorer for the duration of that agreement.

Sponsored feeds are those supported by an integrator through a subscription (e.g. heartbeat or deviation). Projects utilizing sponsored feeds, but are not paying for the feed, should do so at their own risk. Sponsors may change or remove support at their own discretion.

Sunsetting sponsored feeds​

Projects which fail to adhere to subscription agreements risk disruptions to their feeds; Orcfax maintains the right to halt feed publication for non-payment.

Showcase feeds​

To demonstrate the kinds of feeds which integrators can utilize in their dApps, Orcfax may periodically select feeds from its catalogue and highlight them through publication on productions and/or preproduction networks. These feeds will be designated as Sponsored on the Explorer.

warning

Orcfax may change or remove support for showcase feeds at its discretion and may do so without notice. Integrators who would like to take advantage of these feeds or are interested in learning more about our services should contact us via Discord or email.

Removal of feed support​

Unless a feed is sponsored and paid for by a third-party, or subsidized through Orcfax, we may suspend or remove technical support for feeds at our own discretion.
