...Frequently asked questions
What is the Chainlink Data Feed IDL?
The Chainlink Data Feed IDL (Interface Definition Language) is a JSON schema that describes the on-chain program interface for the Chainlink Data Feed smart contract on Solana. It defines all available instructions, account structures, events, and types needed to interact with the program. This one has 3 instructions, 1 account types, 0 events and 2 type definitions.
How do I use the Chainlink Data Feed IDL in my project?
You can use the Chainlink Data Feed IDL with Anchor framework clients in TypeScript (@coral-xyz/anchor), Rust (anchor-client), or Python (anchorpy). Download the JSON file, import it in your project, and use it to create a Program instance that can call instructions and decode accounts.
What is the Chainlink Data Feed program address on Solana?
The Chainlink Data Feed program is deployed at address HEvSKofvBgfaexv23kMabbYqxasxU3mQ4ibBMEmJWHny on Solana mainnet.
What version of the Chainlink Data Feed IDL is this?
This is version 0.1.0 of the Chainlink Data Feed IDL. IDL versions follow program deployments and change as the protocol evolves, so check it against the program on-chain before you integrate.
Build on Chainlink Data Feed with AllenHark
Stream the program's accounts and transactions with Yellowstone gRPC, read its state over Solana RPC, or see its transactions before the block is built with ShredStream. To trade against it, try the trading bots or the PumpFun sniper.
