Overview

• The Raydium AMM is an on-chain smart contract based on the “constant product” in a permissionless and decentralized manner built on the Solana blockchain.And it also shares its liquidity according to the Fibonacci sequence in the form of limit orders on OpenBook, the primary central limit order book (CLOB) of Solana
• The aduit process is here
• The dev document is here

Environment Setup

1. Install Rust.
2. Install Solana and then run solana-keygen new to create a keypair at the default location.

Build

Clone the repository and enter the source code directory.

git clone https://github.com/raydium-io/raydium-amm
cd raydium-amm/program

Mainnet Build

cargo build-bpf

Devnet Build

cargo build-bpf --features devnet

Localnet Build

You must update these pubkeys in the "config_feature" as yours over the localnet feature before build;

cargo build-bpf --features localnet

After building, the smart contract files are all located in the target directory.

Deploy

solana deploy

Attention, check your configuration and confirm the environment you want to deploy.

QuickStart

1. You must have an openbook market not associated to any amm pool if you want to initialize a new amm pool. And you can refer to ListMarket to create a new market.

2. Add dependencies in your Cargo.toml

[dependencies]
raydium-library = { git = "https://github.com/raydium-io/raydium-library" }
spl-token = { version = "4.0.0", features = ["no-entrypoint"] }
spl-associated-token-account = { version = "2.2.0", features = [
    "no-entrypoint",
] }
spl-token-2022 = { version = "0.9.0", features = ["no-entrypoint"] }
solana-client = "<1.17.0"
solana-sdk = "<1.17.0"
anyhow = "1.0.53"

3. Import dependent libraries

#![allow(dead_code)]
use anyhow::{format_err, Result};
use raydium_library::amm;
use std::str::FromStr;
use solana_client::rpc_client::RpcClient;
use solana_sdk::{
    compute_budget::ComputeBudgetInstruction, pubkey::Pubkey, signature::Signer,
    transaction::Transaction,
};

2. initialize a new amm pool with an associate openbook market

// config params
