Jito Go SDK

This library contains tooling to interact with Jito Labs MEV software. ⚠️ Work in progress. ⚠️

We currently use gagliardetto/solana-go to interact with Solana. PRs and contributions are welcome.

💾 Installing

Go 1.22.0 or higher.

go get github.com/MilanFt/jito-go@latest

If you want to run tests:

1. Install Task.
2. Initialize your .env file by running task install:<os> (darwin/linux/windows).
3. Run tests with task test.

🔑 Keypair Authentication

To access Jito MEV functionalities, you'll need a whitelisted Public Key obtained from a fresh KeyPair; submit your Public Key here. In order to generate a new KeyPair, you can use the following function GenerateKeypair() from the /pkg package.
