...Frequently asked questions
What is the Lifinity v1 IDL?
The Lifinity v1 IDL (Interface Definition Language) is a JSON schema that describes the on-chain program interface for the Lifinity v1 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 4 type definitions.
How do I use the Lifinity v1 IDL in my project?
You can use the Lifinity v1 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 Lifinity v1 program address on Solana?
The Lifinity v1 program is deployed at address EewxydAPCCVuNEyrVN68PuSYdQ7wKn27V9Gjeoi8dy3S on Solana mainnet.
What version of the Lifinity v1 IDL is this?
This is version 0.1.1 of the Lifinity v1 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 Lifinity v1 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.
