K256 SDK

Official Rust SDK for K256 - the gateway to Solana’s liquidity ecosystem.

Connect any application to Solana’s liquidity ecosystem. One API. All venues. Full observability.

Quick Start

use k256_sdk::{K256WebSocketClient, Config};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = K256WebSocketClient::new(Config {
        api_key: std::env::var("K256_API_KEY")?,
        ..Default::default()
    });

    client.on_pool_update(|update| {
        println!("Pool {}: slot={}", update.pool_address, update.slot);
    });

    client.connect().await?;
    Ok(())
}
