Extend your routing across chains.

Add native cross-chain routes to your aggregator with one API covering 14 liquidity providers, from Bitcoin to Solana.

Single-chain routing stops at the bridge.

Aggregators find the best price within a chain. SwapKit adds the cross-chain leg, native Bitcoin included, choosing among cross-chain providers and in-chain DEX aggregators such as 1inch and Jupiter.

What you get

Native cross-chain routes

Bitcoin in and out without wrapped assets, plus EVM chains, Solana and more.

A catalogue you can sync

Tokens, networks and every route as static files at tokens.swapkit.dev. No API key needed.

Errors you can route on

How it works

1
Sync the catalogue

Pull tokens.json, networks.json and a paths file per chain to know every route.
2
Quote across providers

Routes come back tagged RECOMMENDED, FASTEST and CHEAPEST.
3
Build and track

Get a ready-to-sign transaction, then follow the swap to completion.

Terminal

curl -X POST "https://api.swapkit.dev/v3/quote" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $SWAPKIT_API_KEY" \
  -d '{"sellAsset":"BTC.BTC","buyAsset":"ETH.ETH","sellAmount":"0.1","slippage":3}'
