By providing liquidity — and that job now belongs to your own AI Cashier: an open-source autonomous agent you run yourself (see the AI Cashier tab, github.com/dhyabi2/AtomicSwapCashier). It prices offers from the live market, posts and reprices them, accepts only trades it certifies as profitable after fees, and settles them end to end. Early providers face less competition, but it is not a guaranteed return: no trades, no earnings.

No. This runs entirely in your browser with no server of ours in the middle. Your key is generated here, encrypted with your passphrase (memory-hard Argon2id → AES-256-GCM), and never leaves this device. A swap is enforced by cryptography, 2-of-2 joint accounts and adaptor signatures, not by trusting us or anyone else.

Every completed step is saved on your device and no step can run twice. Reopen the page (wallet unlocked) and the swap under Unfinished swaps resumes: it first tries to re-connect and finish the swap (both sides can re-establish their encrypted channel from saved material), and only if the other side never returns does it unwind — the built-in refund returns your XNO, or your locked XMR is reclaimed from the counterparty’s refund, automatically. Progress bars show every wait. Still: keep the page open during a swap and use small amounts while this is young.

None. No sign-up, no KYC. You just choose a passphrase, which encrypts a wallet held only in this browser.

We charge no platform fee. Nano is feeless; the only cost is Monero’s small network fee (the app pays the low-priority rate — a fraction of a cent). The maker’s spread is in the offer price you see and accept up front; there is nothing added afterwards.

Nobody central. It's a peer-to-peer order book. When you provide, your offer is priced from the live market rate plus a spread that scales with volatility. When you swap, you pick the best offer that's open. The app may show the going market price from a reference exchange as a guide, but nobody is forced to use it, if an offer is priced badly, traders just pick another. That's what keeps it trustless: there is no rate-setter to trust.

The minimum exists because every swap pays one fixed Monero network fee: below some size, the fee eats the maker’s entire margin and they would decline you — so the app computes the smallest amount the maker will actually accept, roughly fee ÷ (the offer’s margin over the live market). That denominator is tiny — a maker’s edge is a fraction of a percent — so a small wobble in the market price swings the minimum a lot: an offer 0.6% under market with a thin margin can see its minimum double on a 0.15% price move. That is arithmetic, not a bug. To keep it usable the shown minimum is damped: it rises immediately when the market moves against you (a higher floor only ever protects you from a decline) but drifts down slowly, and it includes a safety margin so entering the shown amount clears the maker’s gate even when your price feed and theirs differ slightly. Bigger offers with wider margins have calmer minimums.

The Nano side is near-instant. The Monero side needs about 10 confirmations (~20 minutes) before it is spendable — that is Monero consensus, and the wait is narrated with a live progress bar. Some makers offer the instant tier: they release your XNO after only ~2 confirmations (~4 minutes) and carry the early-release risk themselves, priced into their spread — you see it plainly on the accept and your safety is unchanged.

An exchange holds your coins, it can freeze them, lose them, or demand your ID. Here nothing is ever custodied: the two coins settle directly against each other on-chain, so there's no company standing between you and your funds.

Normally the XNO you buy becomes claimable only after your Monero lock has 10 confirmations (~20 min). A maker running the AI Cashier can promise, inside its cryptographically signed accept, to release after just ~2 confirmations (~4 min). The maker alone carries the small chain-reorganisation risk beyond that depth — it is a business decision priced into their spread and capped per fill. Your safety never changes on any tier, and the promise cannot be forged or altered: it is bound into the maker’s signature.

Yes — limit orders, right in the browser. Under the swap panel, set a target price and amount, fill your receive address, and press Arm. Keep the tab open with the wallet unlocked and the page takes a live offer the moment it meets your target — through exactly the same protections as a manual take. It executes once, then disarms, and it never re-arms itself after a reload: spending always requires a fresh click.

You take a live offer; your browser and the maker’s co-sign the settlement over an encrypted relay, each holding only its own key share. The maker’s acceptance is signed by the on-chain account that posted the offer — including its price reference and any instant-tier promise — so an impostor cannot slip into the middle. Nobody, not us and not the other party, can move your coins without your half of the signature.

Yes — back up both. Back up seed restores everything in this app on any device. For Monero in a different wallet (Cake, Feather), use Back up Monero key: this app derives Monero keys from your seed differently, so the seed alone will not find your Monero there — the spend key will. If you clear this site's data with no backup, the wallet is gone for good. Nobody, including us, can recover it for you.

Largely, with one honest caveat. The swap is non-custodial and uses real ring signatures and decoys, and the Monero you buy goes straight to the external address you enter — use a fresh subaddress of your own wallet each time and your swaps stay unlinkable. The caveat is the small in-app wallet used to fund and operate swaps: it reuses one Monero address, so activity through it is linkable to itself. Keep it as working capital, not savings, and forward anything sensitive onward.

Honestly: not yet by an independent third party. The cryptography is backed by adversarial test suites, and the two-party refund and recovery paths have executed on real funds on-chain — money interrupted mid-swap came back, on both legs. The full happy-path settlement between two independent parties is being exercised now with small amounts. Treat this as an experiment, not a product, and only use what you would shrug off losing.

Nano (XNO) and Monero (XMR) only, for now. More may be added later, the design is direction-agnostic.
