//! Instructions for interacting with the Pump.fun program.
|
||||
//!
|
||||
//! This module contains instruction builders for creating Solana instructions to interact with the
|
||||
//! Pump.fun program. Each function takes the required accounts and instruction data and returns a
|
||||
//! properly formatted Solana instruction.
|
||||
//!
|
||||
//! # Instructions
|
||||
//!
|
||||
//! - `create`: Instruction to create a new token with an associated bonding curve.
|
||||
//! - `buy`: Instruction to buy tokens from a bonding curve by providing SOL.
|
||||
//! - `sell`: Instruction to sell tokens back to the bonding curve in exchange for SOL.
