Anchor Liquidity Pool: build and test a Solana swap program

Understand the project

Practical overview

Use it as a code example when exploring a constant-product Solana token-swap pool and its localnet test workflow.

Solana developers studying or adapting an Anchor liquidity-pool program.
Developers seeking a localnet example for testing pool creation, deposits, withdrawals and swaps.

Build the example Solana program.
Deploy it to localnet using the documented workflow.
Run tests covering pool creation, token deposits and withdrawals, and swaps.
Inspect how the example handles LP-token minting and burning around deposits and withdrawals.

Before you choose

The repository is public on GitHub. No license information is provided in the repository evidence.

The curve is always constant product in this implementation.
The fee receiver is always the admin.
The documented deployment target is localnet and the README calls for 10 SOL by airdrop.
The README identifies the repository as an example implementation for solana-swap.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Follow the repository’s documented build, local deployment and test sequence for its pool operations.

Set ADMIN_PUBKEY to the result of solana address.
Run the command below.
Documented command
```
npm run build
```
Start the local validator with the command below.
Documented command
```
npm run validator
```
Obtain 10 SOL by airdrop, then deploy with the command below.
Documented command
```
npm run deploy
```
Run the command below for the documented pool creation, deposit, withdrawal and swap tests.
Documented command
```
npm run test
```

The repository’s test workflow covers pool creation, deposits, withdrawals and swaps against the localnet program.

This workflow is for localnet; the README does not describe a production deployment process.
The implementation always uses a constant-product curve and sends fees to the admin.
