Installation

[dependencies]
openoc = "0.1"
tokio = { version = "1", features = ["full"] }

Quick Start

use openoc::{Client, Chain, QuoteRequest};

#[tokio::main]
async fn main() -> Result<(), openoc::Error> {
    let client = Client::new()?;

    // Get a quote for swapping 1 ETH to USDC
    let request = QuoteRequest::new(
        "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", // Native ETH
        "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
        "1", // 1 ETH (human readable)
    ).with_gas_price("30000000000");

    let quote = client.get_quote(Chain::Eth, &request).await?;
    println!("Output: {} USDC", quote.out_amount);

    Ok(())
}

Getting Transaction Data

use openoc::{Client, Chain, SwapRequest};

#[tokio::main]
async fn main() -> Result<(), openoc::Error> {
    let client = Client::new()?;

    let request = SwapRequest::new(
        "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
        "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
        "1", // Human readable amount
        "0xYourWalletAddress",
    ).with_slippage(1.0);

    let swap = client.get_swap_quote(Chain::Eth, &request).await?;

    // Ready to sign and send
    println!("To: {}", swap.to);
    println!("Data: {}", swap.data);
    println!("Value: {}", swap.value);

    Ok(())
}
