Practical overview
When it fits
Use it when designing or developing a Solana application where state scale, storage footprint, or on-chain cost is a significant consideration.
Who it is for
- Solana application developers
- Engineers evaluating compressed state management
- Teams building blockchain software in Rust or integrating with Rust-based infrastructure
Documented uses
- Build a Solana application using ZK-compressed state to reduce on-chain storage costs.
- Develop an integration for more economical Solana state management.
- Evaluate a protocol approach to reducing the footprint of Solana state.
Requirements & limits
The project is publicly accessible on GitHub and is licensed under Apache-2.0.
- Whether the application is built for the Solana ecosystem.
- Whether ZK compression fits the application’s state-management design.
- Whether a Rust-based, Apache-2.0-licensed project suits the development context.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set Up and Build the Light Protocol Development Environment
Prepare a Linux or macOS development environment and build the Light Protocol project.
Before you start
- Linux or macOS; Windows is not supported.
- Ubuntu, Fedora, or Arch requires the documented clang and lld packages; macOS requires LLVM installed with Homebrew.
- The repository must be available locally.
- The devenv.sh workflow requires Docker only for the development-container option; the manual workflow requires Rustup with stable and nightly toolchains, Node.js 20.9.0 LTS, and Anchor 0.29.0.
Steps
Install the platform-specific clang and lld prerequisites, or use the documented manual prerequisites.
From the repository, run
./scripts/install.sh; use./scripts/install.sh --full-keyswhen the full production key set is needed.Activate the environment with
./scripts/devenv.sh.Generate a local Solana keypair with
solana-keygen new -o ~/.config/solana/id.json.Build the project with
./scripts/build.sh.
Expected outcome
The documented development environment is activated, a local Solana keypair exists, and the project build command has been run.
Guide limitations
- The default key installation provides a subset sufficient for most development and testing; full production keys require the
--full-keysoption. - Development containers are recommended on Linux but have performance problems on macOS.
- The README notes that tooling such as light-sdk-macros and light-sdk is in active development and unaudited.
Run the Documented Light Protocol Tests
Run the repository’s global, program, or SDK test commands after setup.
Before you start
- The development environment must be set up and activated.
- A local Solana keypair must be generated before development or tests.
- Program tests require sequential execution with
--test-threads=1because many start a local prover server.
Steps
Run global tests with
./scripts/test.sh, or choose a documented test target.For program tests, run the command below.
cargo test-sbf -p account-compression-test -- --test-threads=1For the stateless SDK, run
cd js/stateless.jsfollowed bypnpm test.For the compressed-token SDK, run
cd js/compressed-token.jsfollowed bypnpm test.
Expected outcome
The selected documented test command is executed against the Light Protocol repository.
Guide limitations
- The sources do not provide expected test results or guarantee that tests pass.
- The program-test command covers the account-compression test target, not every program test.
- The sources do not document deployment, production operation, or application-level execution.
