Swap Solana Tokens in Go Without the Headaches

jupiter-go

I'm excited to share with all of you jupiter-go, a library that makes interacting with Jupiter's DEX aggregator straightforward for Go developers. If you're building apps that need to swap tokens on Solana, this might just make your life a whole lot easier.

Have you ever tried writing backend code to swap tokens on Solana? There's a lot to handle. Getting quotes, building transactions, signing them, sending them to validators, checking if they worked... it's a lot of moving parts. I wanted something that just worked without having to handle all the complexity.

What's Inside?

The library bundles everything you need:

• A Jupiter API client for getting quotes and swap instructions
• A Solana client to send your swaps to the blockchain
• A transaction monitor that watches your transactions until they're confirmed
• From version 0.1.0, it fully supports Jito tips

Everything is designed with simplicity in mind while still giving you the flexibility to handle advanced scenarios.

Getting Started is Easy

Installation is straightforward with a simple go get:

go get github.com/ilkamo/jupiter-go

And getting a quote to swap SOL to another token takes just a few lines of code:

jupClient, _ := jupiter.NewClientWithResponses(jupiter.DefaultAPIURL)
slippageBps := float32(250.0)  // 2.5% slippage

quoteResponse, _ := jupClient.GetQuoteWithResponse(ctx, &jupiter.GetQuoteParams{
    InputMint:   "So11111111111111111111111111111111111111112",  // SOL
    OutputMint:  "JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN",  // JUP
    Amount:      100000,  // in smallest units (lamports)
    SlippageBps: &slippageBps,
})

Give It a Try
