# Basic Operations - Native Rust Programs

Native Solana programs with basic compressed account operations.

## Programs

- **create** - Initialize a new compressed account
- **update** - Modify data in an existing compressed account
- **close** - Close a compressed account and reclaim rent
- **reinit** - Reinitialize a previously closed compressed account
- **burn** - Permanently destroy a compressed account (cannot be reinitialized)

## Build

Build all programs in the workspace:

```bash
cargo build-sbf
The compiled .so files will be in target/deploy/

​
Test

​
Requirements

  • light cli version 0.24.0+ (install via npm i -g @lightprotocol/zk-compression-cli)
  • solana cli version 2.1.16+
  • Node.js and npm

​
Running Tests

​
Rust Tests

cargo test-sbf

​
TypeScript Tests

  1. Build the programs: 
    cargo build-sbf
  2. Start the test validator with deployed programs: 
    light test-validator \
  --sbf-program "<PROGRAM_ID_CREATE>" ./target/deploy/create.so \
  --sbf-program "<PROGRAM_ID_UPDATE>" ./target/deploy/update.so \
  --sbf-program "<PROGRAM_ID_CLOSE>" ./target/deploy/close.so \
  --sbf-program "<PROGRAM_ID_REINIT>" ./target/deploy/reinit.so \
  --sbf-program "<PROGRAM_ID_BURN>" ./target/deploy/burn.so
    NOTE: Replace program IDs with those defined in each program’s lib.rs (pub const ID).
  3. Install dependencies and run tests: 
    npm install

npm test
The TypeScript tests demonstrate client-side interaction with compressed accounts using @lightprotocol/stateless.js and @lightprotocol/zk-compression-cli. light test-validator spawns the following background processes:
  1. solana test validator http://127.0.0.1:8899
  2. prover server http://127.0.0.1:3001
  3. photon indexer http://127.0.0.1:8784
You can kill these background processes with lsof -i:<port> and kill <pid>.
