Price Feeds

All asset prices are fully operated and maintained by the Vela team via a proprietary price feed service called Vela Stream
TM^{\scriptsize \scriptstyle TM}
, and are built to ensure performance, security, and flexibility. The platform currently pulls data directly from several CEXs and on-chain resources into a proprietary Vela Exchange price feed.
The Vela Stream price feeds are published on-chain and transparently for every tradeable asset and reflects a single aggregated price for top CEXs in the ecosystem.

Data Sources

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


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.


Multiple layers of redundancy power our data sources, allowing for fall backs incase 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.
