The Solana Program Library (SPL) is a collection of on-chain programs targeting the Sealevel parallel runtime. These programs are tested against Solana's implementation of Sealevel, solana-runtime, and deployed to its mainnet. As others implement Sealevel, we will graciously accept patches to ensure the programs here are portable across all implementations.
Full documentation is available at https://spl.solana.com
- Install the latest Rust stable from https://rustup.rs/
- Install Solana v1.6.1 or later from https://docs.solana.com/cli/install-solana-cli-tools
- Install the
libudevdevelopment package for your distribution (
libudev-devon Debian-derived distros,
The normal cargo build is available for building programs against your host machine:
$ cargo build
To build a specific program, such as SPL Token, for the Solana BPF target:
$ cd token/program $ cargo build-bpf
Unit tests contained within all projects can be run with:
$ cargo test # <-- runs host-based tests $ cargo test-bpf # <-- runs BPF program tests
To run a specific program's tests, such as SPL Token:
$ cd token/program $ cargo test # <-- runs host-based tests $ cargo test-bpf # <-- runs BPF program tests
Integration testing may be performed via the per-project .js bindings. See the token program's js project for an example.
$ cargo clippy
$ ./coverage.sh # Please help! Coverage build currently fails on MacOS due to an XCode `grcov` mismatch...
You may need to pin your grcov version, and then rustup with the apple-darwin nightly toolchain:
$ cargo install grcov --version 0.6.1 $ rustup toolchain install nightly-x86_64-apple-darwin
SPL programs are currently tagged and released manually. Each program is versioned independently of the others, with all new development occurring on master. Once a program is tested and deemed ready for release:
- Increment the version number in the program's Cargo.toml
- Generate a new program ID and replace in
cargo build-bpf <program>to update relevant C bindings. (Note the location of the generated
spl_<program>.sofor attaching to the Github release.)
- Open a PR with these version changes and merge after passing CI.
Program tags are of the form
Create the new tag at the version-bump commit and push to the
solana-program-library repository, eg:
$ git tag token-v1.0.0 b24bfe7 $ git push upstream --tags
- Go to GitHub Releases UI
- Click "Draft new release", and enter the new tag in the "Tag version" box.
- Title the release "SPL vX.Y.Z", complete the description, and attach the
- Click "Publish release"
Navigate to the program directory and run
to test the build. Then run
All claims, content, designs, algorithms, estimates, roadmaps, specifications, and performance measurements described in this project are done with the Solana Foundation's ("SF") best efforts. It is up to the reader to check and validate their accuracy and truthfulness. Furthermore nothing in this project constitutes a solicitation for investment.
Any content produced by SF or developer resources that SF provides, are for educational and inspiration purposes only. SF does not encourage, induce or sanction the deployment, integration or use of any such applications (including the code comprising the Solana blockchain protocol) in violation of applicable laws or regulations and hereby prohibits any such deployment, integration or use. This includes use of any such applications by the reader (a) in violation of export control or sanctions laws of the United States or any other applicable jurisdiction, (b) if the reader is located in or ordinarily resident in a country or territory subject to comprehensive sanctions administered by the U.S. Office of Foreign Assets Control (OFAC), or (c) if the reader is or is working on behalf of a Specially Designated National (SDN) or a person subject to similar blocking or denied party prohibitions.
The reader should be aware that U.S. export control and sanctions laws prohibit U.S. persons (and other persons that are subject to such laws) from transacting with persons in certain countries and territories or that are on the SDN list. As a project based primarily on open-source software, it is possible that such sanctioned persons may nevertheless bypass prohibitions, obtain the code comprising the Solana blockchain protocol (or other project code or applications) and deploy, integrate, or otherwise use it. Accordingly, there is a risk to individuals that other persons using the Solana blockchain protocol may be sanctioned persons and that transactions with such persons would be a violation of U.S. export controls and sanctions law. This risk applies to individuals, organizations, and other ecosystem participants that deploy, integrate, or use the Solana blockchain protocol code directly (e.g., as a node operator), and individuals that transact on the Solana blockchain through light clients, third party interfaces, and/or wallet software.
