lifiswap

A Rust SDK for the LI.FI cross-chain swap and bridge aggregation API.

Quick Start

use lifiswap::{LiFiClient, LiFiConfig};

# async fn example() -> lifiswap::error::Result<()> {
let client = LiFiClient::new(
    LiFiConfig::builder().integrator("my-app").build(),
)?;

let chains = client.get_chains(None).await?;
eprintln!("supported chains: {}", chains.len());
# Ok(())
# }

One-Line Swap

The simplest way to perform a cross-chain swap — one method call does everything: fetch the optimal quote, convert it to a route, and execute it end-to-end.

use lifiswap::{LiFiClient, LiFiConfig};
use lifiswap::types::QuoteRequest;

let client = LiFiClient::new(
    LiFiConfig::builder().integrator("my-app").build(),
)?;
client.add_provider(evm_provider);

let result = client
    .swap(
        &QuoteRequest::builder()
            .from_chain("42161")           // Arbitrum
            .from_token("0xaf88d065...")    // USDC
            .from_address("0xYourWallet")
            .from_amount("10000000")        // 10 USDC
            .to_chain("10")                 // Optimism
            .to_token("0xDA10009c...")      // DAI
            .build(),
        Default::default(),
    )
    .await?;

Step-by-Step Control

For more control, break the flow into individual steps:

// 1. Get a quote
let quote = client.get_quote(&request).await?;

// 2. Execute the quote directly
let result = client.execute_quote(quote, Default::default()).await?;

// Or: get multiple routes and pick one
let routes = client.get_routes(&routes_request).await?;
let result = client.execute_route(routes.routes[0].clone(), Default::default()).await?;
