The rust-sdk provides a convenient way to interact with the DAMM v2 program and get swap quotes. Before you begin, here are some important resources:
  • Program ID (Mainnet & Devnet): cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG
  • Rust SDK: DAMM v2

​
Getting Started

To use the Rust SDK, you need to add it as a dependency in your Cargo.toml file. Since it’s a local dependency in this workspace, you can add it by specifying its path: 
[dependencies]
rust-sdk = { path = "../rust-sdk" } # Adjust the path accordingly
cp-amm = { path = "../programs/cp-amm" } # The sdk also needs the cp-amm crate
solana-sdk = "1.18.12" # For Pubkey
