SOLANA RPC Canister  

A canister for interaction between Solana and Internet Computer (ICP) blockchains.

Overview

The SOLANA RPC canister is an ICP canister for communicating with Solana using an on-chain API.

This canister sends API requests to JSON-RPC services using HTTPS outcalls. This enables functionality similar to traditional Solana dApps, including querying Solana smart contract states and submitting raw transactions.

The canister runs on the 28-node fiduciary subnet with the following principal: bkyz2-fmaaa-aaaaa-qaaaq-cai.

For information on how to verify a hash of a deployed WebAssembly module, please refer to the Reproducible Builds section.

Quick start

Add the following to your dfx.json config file (replace the ic principal with any option from the list of the available canisters above):

{
  "canisters": {
    "ic-solana-provider": {
      "type": "custom",
      "candid": "https://github.com/mfactory-lab/ic-solana/releases/latest/download/ic-solana-provider.did",
      "wasm": "https://github.com/mfactory-lab/ic-solana/releases/latest/download/ic-solana-provider.wasm.gz",
      "remote": {
        "id": {
          "ic": "bkyz2-fmaaa-aaaaa-qaaaq-cai",
          "playground": "bkyz2-fmaaa-aaaaa-qaaaq-cai"
        }
      }
    }
  }
}

Running the project locally

If you want to test your project locally, you can use the following commands:

# Starts the replica, which then runs in the background
dfx start --clean --background

# Build and deploy your canisters to the replica and generates your candid interface
make build

Once the job is completed, your application will be available at http://localhost:4943?canisterId={asset_canister_id}.

Testing

We use PocketIC for integration testing. Please make sure to have it installed and the POCKET_IC_BIN environment variable set to the path of the pocket-ic binary.

You can run the tests with the following command:

make test

Deployment on the Internet Computer

The canister is deployed to bkyz2-fmaaa-aaaaa-qaaaq-cai.

You can check the Candid UI at https://a4gq6-oaaaa-aaaab-qaa4q-cai.raw.icp0.io/?id=bkyz2-fmaaa-aaaaa-qaaaq-cai.

Interaction with Blast Playground

You can interact with the canister using the Blast Playground.

To do

• Versioned transactions.
• Native support of threshold EdDSA.

Reproducible builds

The SOLANA RPC canister supports reproducible builds:

1. Ensure Docker is installed on your machine.
2. Run scripts/docker-build in your terminal.
3. Run sha256sum ic-solana-provider.wasm.gz on the generated file to view the SHA-256 hash.

In order to verify the latest SOLANA RPC WASM file, please make sure to download the corresponding version of the source code from the latest GitHub release.
