pinocchio-raydium-cpmm-cpi

Overview

This crate contains pinocchio helpers to perform cross-program invocations (CPIs) for Raydium CPMM instructions.

Each instruction defines a struct with the accounts and parameters required. Once all values are set, you can call directly invoke or invoke_signed to perform the CPI.

This is a no_std crate.

Note: The API defined in this crate is subject to change.

Examples

Initializing a CPMM pool:

// This example assumes that the instruction receives all required accounts
// for pool creation including creator, amm_config, authority, pool_state, etc.
InitializeCpmm {
    creator,
    amm_config,
    authority,
    pool_state,
    token_0_mint,
    token_1_mint,
    lp_mint,
    creator_token_0,
    creator_token_1,
    creator_lp_token,
    token_0_vault,
    token_1_vault,
    create_pool_fee,
    observation_state,
    token_program,
    token_0_program,
    token_1_program,
    associated_token_program,
    system_program,
    rent,
    init_amount_0: 1000000,
    init_amount_1: 1000000,
    open_time: 1640995200, // Unix timestamp
}.invoke()?;

Performing a swap with base input:

// This example assumes that the instruction receives all required accounts
// for swapping including payer, authority, pool_state, token accounts, etc.
SwapBaseInput {
    payer,
    authority,
    amm_config,
    pool_state,
    input_token_account,
    output_token_account,
    input_vault,
    output_vault,
    input_token_program,
    output_token_program,
    input_token_mint,
    output_token_mint,
    observation_state,
    amount_in: 1000000, // Amount of input tokens to swap
    minimum_amount_out: 950000, // Minimum output tokens expected
}.invoke()?;
