Cross-chain swaps for your users' balances.
Offer native swaps across 30+ chains from one integration, with every address screened before a transaction is built.
01
Your users hold more than one chain.
Exchange and custody customers hold Bitcoin, EVM assets, Solana and more. SwapKit gives you native cross-chain swaps through one API instead of an integration per protocol, while your systems keep every signature.
02
Built for regulated operations
Address screening on every swap
Every address in a swap request is screened for AML risk. An address can get a quote and still be refused before anything is built.
Payloads you can verify
Transaction payloads can be signed per API key, so you can check nothing was altered in transit. SLIP-0024 is supported for hardware devices.
Learn more →Limits per key
Each key has its own request and trade-size limits. Raise them in the dashboard or with the SwapKit team.
03
Turn swaps into revenue
Set your own affiliate fee, anywhere from 0 to 1,000 bps. It's added to every swap your users make and paid to your addresses automatically, with volume and earnings tracked per app in the dashboard.

Questions
Does SwapKit ever hold funds?
No. SwapKit builds transactions; your systems sign and broadcast them. SwapKit never holds keys or funds.
What happens if an address fails screening?
The swap request is refused before a transaction is built, so nothing reaches signing.
Can we restrict which providers are used?
Yes. Pass the providers you allow and routing stays within them.
Are there limits on trade size?
New keys allow 10 requests per minute per service and trades up to $1,000. Both are raised on request for production volumes.
