Getting Started

Make sure you have Rust and Solana installed.

• Rust: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Solana: sh -c "$(curl -sSfL https://release.solana.com/v1.18.12/install)"

For typescript, either install npm or yarn.

You should now be able to build the program and run the test validator with the loaded program:

cargo build-sbf
./start-test-validator

If this fails, you may need to add a compiler flag. See here: https://solana.stackexchange.com/questions/6987/mac-platform-tools-1-16-cargo-build-sbf-error-failed-to-run-custom-build

To regenerate the typescript SDK, you can run the following script:

cd idl
node generateIdlAndClient.js

This will create a JSON file with the program schema as well as a rudimentary typescript client for decoding accounts and building instructions. If the script fails, you might need to install Shank and anchor-client-gen.

• Shank: cargo install shank-cli
• anchor-client-gen:

# npm
$ npm install --global anchor-client-gen

# yarn
$ yarn global add anchor-client-gen

To run the typescript tests:

• Make sure you have the test validator running
• Run the following

cd plasma-sdk
yarn       # (or npm install)
yarn test  # (or npm run test)

• Optionally you can also run the following script to parse the logs from the local validator

tsx examples/plasmaLogSubscribe.ts # (You can also use ts-node)
