CLMM Swap Contract on Solana

This is a Concentrated Liquidity Market Maker (CLMM) implementation built on Solana using the Anchor framework. It allows users to perform token swaps with fine-grained liquidity ranges, similar to Uniswap V3.

---

Overview

The CLMM Swap contract is designed to provide a flexible and efficient platform for token swaps on Solana. It allows users to swap tokens with a range of liquidity, similar to Uniswap V3. The contract uses a tick-based approach, where each tick represents a price range and liquidity is provided in terms of ticks.

Architecture

The CLMM Swap contract is built using the Anchor framework, which provides a high-level interface for building Solana programs. The contract is composed of several modules:

• State: Defines the data structures and state variables for the contract.
• Math: Contains mathematical functions for computing prices, liquidity, and swap amounts.
• Errors: Defines custom error types for handling errors in the contract.
• Instructions: Defines the instructions for interacting with the contract, including initialize_pool, provide_liquidity, remove_liquidity, and swap.

Usage

To use the CLMM Swap contract, you can follow these steps:

1. Clone the repository:

git clone https://github.com/darrendc26/clmm-dex.git

2. Navigate to the clmm-dex directory:

cd clmm-dex

3. Install the dependencies:

cargo install --path .

4. Build the contract:

anchor build

5. Deploy the contract:

anchor deploy

6. Initialize the pool:

anchor idl init --filepath target/idl/clmm_dex.json --provider.cluster devnet --provider.wallet ~/.config/solana/id.json

7. Provide liquidity:

anchor idl invoke --filepath target/idl/clmm_dex.json --provider.cluster devnet --provider.wallet ~/.config/solana/id.json --program-id <program-id> provide_liquidity --tick_lower <tick_lower> --tick_upper <tick_upper> --liquidity <liquidity>

8. Remove liquidity:

anchor idl invoke --filepath target/idl/clmm_dex.json --provider.cluster devnet --provider.wallet ~/.config/solana/id.json --program-id <program-id> remove_liquidity

9. Swap:

anchor idl invoke --filepath target/idl/clmm_dex.json --provider.cluster devnet --provider.wallet ~/.config/solana/id.json --program-id <program-id> swap --amount_in <amount_in> --a_to_b <a_to_b>

10. Check the contract state:

anchor idl inspect --filepath target/idl/clmm_dex.json --provider.cluster devnet --program-id <program-id>
