Price Feeds

PreviousFeesNextRisk Mitigation

Last updated 1 year ago

All asset prices are fully operated and maintained by the Vela team via a proprietary price feed service called Vela StreamTM^{\scriptsize \scriptstyle TM}TM, and are built to ensure performance, security, and flexibility.

#PoweredByPyth

Vela StreamTM^{\scriptsize \scriptstyle TM}TMuses Pyth Network as the backbone for aggregation and features the most robust and trustworthy sub-second price accuracy in DeFi. Rather than using the legacy model of off-chain price feeds (which push updates), Pyth features an on-demand price update model that excels in periods of volatility.

Our partnership with Pyth has enabled us to collaborate at a ground level with their architects and engineers to ensure support for our use-cases and drive innovation in a collaborative nature.

Pyth offers several key advantages:

  • Financial data from close to 100 first-party sources

  • Price feeds for several classes of assets ranging from crypto to traditional financial assets

  • Aggregation that happens on a sub second level, multiple times a second

While Pyth will be the primary data source, we will still be operating our own public price feeds to maintain flexibility, and our current architecture will support additional price feeds for fallbacks and other reliability needs. You can review a list of our VelaIds .

Refresh Rates

Data is refreshed and ingested on variable intervals depending on asset type.

Data Sources

Vela Exchange aggregates data from top centralized exchanges including Kraken, Bitfinex, Coinbase, and other sources.

Latency

All latency related to price feeds is at a sub-millisecond level (<1 millisecond). Our data providers operate on enterprise level data centers close to data sources.

Redundancy

Multiple layers of redundancy power our data sources, allowing for fall backs in case primary data sources experience outages or irregularities.

In Q2 2023, the infrastructure plan includes fall backs to Chainlink Oracles in the event of a severe outage, although this is subject to change based on pending updates of the Chainlink Oracle infrastructure that will provide faster price feeds.
