Data Streams
Overview
Chainlink Data Streams are a secure, fast, and high-performance pull-based oracle solution delivering real-time market data with sub-second latency. Data is streamed and maintained offchain for speed, then cryptographically signed and verified onchain when requested. This approach provides fast, flexible, and secure access to high-frequency data.
What this enables
Data Streams supports advanced DeFi applications such as perpetual futures, options trading, automated liquidations, and high-frequency strategies that require rapid reaction to market changes. By decoupling data delivery from onchain writes, Data Streams significantly reduces costs while enabling real-time responsiveness.
Benefits
- Sub-second latency for high-frequency updates
- Pull-based architecture that reduces unnecessary onchain costs
- Cryptographic verification for trust-minimized data usage
- Multi-region, high-availability infrastructure
- Flexible integration for both onchain and offchain processes
Key developer tools
- Data visualization dashboards at https://data.chain.link/streams
- SDKs in Go, TypeScript, and Rust
- REST and WebSocket data access endpoints
- Onchain verifier contract for report validation
Robinhood Chain Implementation
The Data Streams Verifier Proxy facilitates on-chain verification for Data Streams reports. For the Robinhood Chain Mainnet (chain ID 4663), the verifier proxy is located at the following address:
| Network | Verifier Proxy Address |
|---|---|
| Robinhood Chain | 0xcE73c8ad08CBDEaCa6078BF0627C8fe0a9a536E7 |
Developers should invoke the verify() function on this specific contract to authenticate signed reports on-chain prior to execution. For real-time availability updates, refer to the Chainlink network status page for Robinhood Chain.
