GAMMA

Goose Automated Market Making Algorithm (GAMMA) is a decentralized exchange (DEX) protocol built on Solana. It provides dynamic fee AMM functionality with customizable fee structures and liquidity pool management.

Key Features

• Dynamic fees based on volatility and pool rebalancing mechanisms, up to 10% of swap amount
• Permissionless pool creation with low fees (less than 0.1 SOL)
• Migration tool for to transfer LP position from other AMMs
• Referral program and open source code
• Token2022 support
• Highly CU optimized for faster swaps
• $GOFX revenue share and burn mechanism (see docs.goosefx.io for more info)

Developer Features

• Create and manage AMM configurations
• Initialize liquidity pools
• Deposit and withdraw liquidity
• Swap tokens with base input or base output
• Oracle price feed integration
• Transfer fee handling for SPL tokens (Token22 support)

Project Structure

• programs/gamma: Solana program (smart contract) code
• client: Rust client for interacting with the Gamma program

Getting Started

Prerequisites

• Rust and Cargo
• Solana CLI tools
• Anchor framework

Building

To build the project:

cargo make build_all

Deploying

To deploy the program:

cargo make deploy_program

Running the Client

The client provides a command-line interface for interacting with the Gamma program. Use the following command to see available options:

cargo install --path client

Commands

gamma-cli --help

• create-config: Create a new AMM configuration
• initialize-pool: Initialize a new liquidity pool
• init-user-pool-liquidity: Initialize user pool liquidity account
• deposit: Deposit liquidity into a pool
• withdraw: Withdraw liquidity from a pool
• swap-base-in: Perform a token swap with a specified input amount
• swap-base-out: Perform a token swap with a specified output amount

Testing

To run the test suite:

cargo test-sbf

Note: Do not use cargo update, it adds some unwanted dependency version which then causes the compilation to fail. At the time of writing this, it was adding multiple version of solana-sdk and borsh and then the jupiter-library and the external anchor providers we have for those the compilation was failing. If you want to check if the project is compiling its better to use cargo check
