Corda Solana Toolkit

The Gradle modules in this repo are split into two main groups:

• Java utility library for Solana
• Corda to Solana Bridge Authority

To use them specify com.r3.corda.lib.solana for the Maven group and add the following Maven repo:

repositories {
    maven {
        url = uri("https://download.corda.net/maven/corda-dependencies")
    }
}

Java Solana Library

This is composed of three separate modules corda-solana-core, corda-solana-cordapp-utils, and corda-solana-testing.

corda-solana-core

Collection of Corda-compatible Solana utilities built upon Sava. This includes FileSigner for supporting the Solana filesystem wallet and SolanaClient which is an RPC client that honours rate limits and uses the websocket API for efficient waiting of transaction confirmation.

corda-solana-testing

Contains a wrapper around the solana-test-validator which makes it easy to configure and spin up a validator from Java/Kotlin code. There is also SolanaTestClass which wraps this inside a JUnit extension making it trivial to write Solana-based tests.

corda-solana-cordapp-utils

Collection of Solana utilities for CorDapps.

Bridge Authority

This consists of the CorDapp bundle bridge-authority:contracts and bridge-authority:workflows which is a proposed solution for the bridging (and redemption) of Corda assets into Solana tokens. It centers around a "bridge authority" node which can be introduced into a Corda network that already uses the Corda Tokens SDK. More information about how it works and how to use it can be found here.

Project maintenance

The project dependencies are listed in libs.versions.toml. Update them as needed and perform a release when the changes are ready to be published. To create a release perform:

./gradlew currentVersion

This will print the current snapshot version, for example:

Task :currentVersion

Project version: 0.1.9-SNAPSHOT

Add v prefix and remove the -SNAPSHOT suffix to create new tag, for example:

git tag v0.1.9
git push origin v0.1.9

In a build system navigate to a page for the project and use Build With paramaters providing a name of a tag (for example v0.1.9).

The next SNAPSHOT version will be created automatically, when the main branch advances past the tagged commit.
