A Fast, 1 Second Update Interval
The Price Stream is our fastest and most powerful price feed system to date.
Prices get updated continuously on BandChain and sent to smart contracts via leading on-chain messaging protocols.
Secured Through Staking
Like Ethereum and leading L1s and L2s, Band Data Feed is secured via staking.
Only community-elected validators have right to aggregate and report the data, ensuring maximum feeds accuracy.
Fully Open
and Permissionless
Gone were the days where you need to “Contact us” for data feed integrations.
Band Price Stream is fully self-serviced and compatible with most smart contract ecosystems. All source codes are open.
How Concurrent
Price Stream Works
Add Symbol
via Signaling Hub
The Signaling Hub enables anyone to propose new symbols by staking BAND tokens and gaining voting power.
Once a symbol receives sufficient voting power, validators will automatically begin submitting price updates — as frequently as every second.

Price Data Automatically
Streamed On-chain
Each symbol pool adjusts dynamically: the more BAND staked in a symbol pool, the stronger the voting power. This market-driven mechanism allows the symbol list and parameters on BandChain to evolve based on real-time demand.
The entire process is fully permissionless, requiring no third-party intervention — a hallmark of a decentralized and distributed system.
Integrate Price Feeds via
Cross-chain Messaging Protocols
Stream the data from BandChain to any smart contract platforms in collaboration with leading Cross-Chain Messaging Protocols like Axelar and Router Protocol.
