Pump.fun IDL
Pump.fun is the leading Solana memecoin launchpad protocol. Allows users to deploy tokens on a bonding curve and trade them instantly. Tokens automatically migrate to Raydium upon reaching the graduation threshold.

...Frequently asked questions
What is the Pump.fun IDL?
The Pump.fun IDL (Interface Definition Language) is a JSON schema that describes the on-chain program interface for the Pump.fun smart contract on Solana. It defines all available instructions, account structures, events, and types needed to interact with the program. This one has 38 instructions, 6 account types, 23 events and 34 type definitions.
How do I use the Pump.fun IDL in my project?
You can use the Pump.fun 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 Pump.fun program address on Solana?
The Pump.fun program is deployed at address 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P on Solana mainnet.
What version of the Pump.fun IDL is this?
This is version 0.1.0 of the Pump.fun 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 Pump.fun 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.
