Swaps on herrenlos: non-custodial, cross-chain, routed for the best rate

Swapping is the core of herrenlos. The idea is simple: instead of picking one exchange and hoping it has a good price, herrenlos asks several route providers at once, compares what each would actually deliver, and points you at the best executable one — while your funds stay in your own wallet the entire time.

Routed for the best executable rate

When you enter a pair and an amount, herrenlos quotes providers in parallel — today that includes Chainflip, LI.FI, Squid, Rango, OpenOcean, 0x, and ChangeNOW — and ranks the results by what you'll actually receive after the route's own costs, not by who pays us.

That last part matters. The route highlighted as best is the best executable one for your trade, every time — the ranking isn't tilted toward a provider because of a rebate. If two routes are close, you still see them, so the choice is yours.

Native, cross-chain by default

herrenlos is built for moving between ecosystems, not just trading within one. You can swap BTC, ETH, SOL, and major stablecoins like USDC and USDT, alongside many other supported assets — and where a native cross-chain path exists (via Chainflip), herrenlos prefers it, so you skip wrapped tokens and extra bridges when a direct route is available.

The catalog spans 100+ assets across the supported chains. Coverage depends on what the underlying providers support for a given pair — so the honest framing is "a lot, but not everything," and the quote panel is the source of truth for any specific route.

Three ways to swap

Depending on the pair and how you want to sign, herrenlos offers up to three flows:

• Deposit channel — send to a generated address. This works even for chains you sign externally (like Bitcoin), because you're just sending funds to the address herrenlos gives you, with any required memo preserved.
• Vault swap — sign a single wallet transaction in-page. This needs an in-page wallet on the source chain (EVM or Solana), so it isn't offered for chains that sign externally.
• DCA — recurring, chunked swaps for larger orders, so a big trade can be broken into pieces rather than hitting the book all at once.

Which flows are available updates with your selected pair — an option that doesn't apply to your route is disabled rather than hidden behind a dead end.

MEV protection and custody

For supported routes, herrenlos surfaces per-route MEV visibility and offers an opt-in protected broadcast, so a swap can be submitted through a more private path when that's available.

Throughout all of it, the custody model doesn't change:

You sign in your own wallet, your keys never leave it, and there's no herrenlos account and no KYC. Non-custodial isn't a mode you switch on — it's the only mode.

Honest about the limits

herrenlos is a beta product, and swaps are no exception:

1. A quote is a snapshot. Prices move, and the amount you see is an estimate until the route is actually executed.
2. Not every pair has a route at every size. If nothing can be filled cleanly, herrenlos says so instead of showing a broken quote.
3. Providers occasionally go down or rate-limit. When one does, herrenlos routes around it where it can and is honest when it can't — a missing provider means a missing route, never an invented one.

Try it

The fastest way to understand the routing is to watch it happen: open the swap page, pick a pair, and enter an amount to see the parallel quotes rank themselves. If you want to know what's coming next across providers and chains, the roadmap lays it out.
