BTC to XMR: swap routes compared

As of mid-July 2026 there are three working ways to swap native BTC for native XMR — instant-exchange (RFQ) desks, Haveno-based P2P networks, and BTC–XMR atomic swaps — with a fourth, THORChain’s native Monero corridor, at the edge of mainnet. The fastest route is an RFQ desk; the most trustless is an atomic swap. Which one fits depends on trade size, patience, and how much counterparty exposure you are willing to hold while the swap is in flight.

Why this corridor is different

Most cross-chain pairs have a lazy default: deposit on a centralized exchange, sell one asset, buy the other, withdraw. For BTC to XMR that default barely exists — most large centralized exchanges have delisted Monero, so the corridor lives almost entirely on specialized rails. That makes route selection a real decision here, not an afterthought. If the mechanics of cross-chain settlement are new to you, start with our pillar on how cross-chain swaps work and the broader Monero swap guide.

The demand side is financial privacy, and it is worth stating plainly what that means. Bitcoin’s ledger is transparent and permanent: a business that pays contractors in BTC publishes its payroll; a fund that settles OTC flow on-chain leaks its counterparties; an individual whose balance is publicly linkable becomes a physical target. Monero addresses this at the protocol level, which is why the corridor exists. Financial privacy is not an exemption from the law: you remain responsible for complying with local regulations and tax obligations wherever you trade, and where KYC is legally required, it applies regardless of the venue you use.

Route 1: instant-exchange and RFQ desks

The workhorse of the corridor. You request a quote for a pair (fixed or floating rate), the desk gives you a BTC deposit address, you send, and after confirmation the desk pays out XMR to your address — typically minutes after the BTC leg confirms. No account, no order book to manage, and most desks in this category (the StealthEX / ChangeNOW mold, plus the aggregators that quote across them) list XMR as a routine pair.

The catch is the custody model. Between your deposit and their payout, the desk holds your funds. That window is short, but everything that can go wrong in this route goes wrong inside it: the desk can hold a deposit its risk systems flag and demand documentation under its own policy, it can misprice and refund at a worse rate, or it can disappear entirely. The category also carries enforcement tail risk when an operator courts illicit flow: eXch, a long-running swap service, was seized by Germany’s BKA in April 2025 with roughly €34M in crypto taken, after allegedly processing on the order of $1.9B in laundered funds. The lesson is not that the category is unusable — it is that a custodial desk in the middle is a single point of failure, and desks that market themselves on ignoring their legal obligations tend to take their users’ in-flight funds down with them.

In every other corridor, custody-in-flight is a cost. In this one, it contradicts the reason for the trade.

Route 2: Haveno P2P networks

Haveno is open-source software — a Bisq-style, Tor-native P2P exchange rebuilt around Monero — and the live order books run on community-operated deployments, of which RetoSwap is the best known. BTC is one of the standard assets traded against XMR, alongside fiat payment methods.

The trade protocol is the draw: maker, taker, and an arbitrator share a 2-of-3 Monero multisig, both sides lock XMR security deposits (typically around 15% of trade size), and the payment leg — your BTC — settles outside the protocol before the seller releases. Deposits take roughly 20 minutes to become spendable, and the full trade usually resolves in hours rather than minutes, depending on the counterparty. No operator ever holds your funds, and disputes go to opt-in arbitration rather than a support ticket. Two practical frictions: the books are thin, so size is limited by whatever maker offers exist; and you generally need XMR before you can buy XMR, because deposits are posted in it — though since v1.0.15 the software supports buying up to 1.5 XMR without an initial deposit, which solves the bootstrap problem for small first trades.

Route 3: atomic swaps

The most trustless route in the corridor, descended from the COMIT protocol work that put BTC–XMR atomic swaps on mainnet in 2021. The original comit-network implementation is explicitly unmaintained; active development continues in the eigenwallet project (the UnstoppableSwap GUI lineage), which ships a desktop interface with Tor built in. Note the fork introduced network-level breaking changes, so old and new implementations cannot swap with each other.

Mechanically, your BTC is locked in an on-chain contract and the maker’s XMR in a scheme whose refunds are enforced by timelocks — either both legs complete or both unwind, with no third party ever touching funds. Two constraints matter. First, direction: the tooling currently supports BTC→XMR only (the XMR-first direction is blocked pending changes on Monero itself) — which happens to be exactly this page’s trade. Second, liquidity: makers are few and clips are small, so this is a route for patience and principle rather than size. You must also stay online through the protocol’s refund windows; abandoning a swap mid-flight can forfeit funds by design.

Route 4: THORChain’s native corridor — and who has no XMR at all

THORChain is on the verge of becoming the first pool-based DEX with a native XMR corridor. The timeline matters for anyone deciding whether to trust it with size: a $10.7M exploit drained one Asgard vault on May 15, 2026; the network halted for 39 days and restarted on June 23 after an 11-stage reactivation; and as of late June the team reported native Monero swaps working end-to-end in testing (reportedly using FROST threshold signatures), with mainnet launch flagged as imminent. When it goes live, it offers what nothing else in this list does: native BTC to native XMR in a single transaction against pooled liquidity, non-custodial, no account, no wrapped assets. As of publication we treat it as brand-new plumbing — check live status and start small.

Two protocols people commonly assume run this corridor do not. Maya Protocol, THORChain’s friendly fork, runs no native XMR pool as of mid-2026 — its pools pair BTC, ETH, DASH, ZEC, RUNE and stables against CACAO, so its privacy-asset corridors are Zcash and Dash, not Monero. Chainflip does not support XMR at all: it settles Bitcoin, Ethereum, and Solana ecosystem assets, and Monero is not on its announced roadmap. For how these pool-based designs differ from lock-and-mint bridges, see cross-chain swap vs bridge.

Fee anatomy of a BTC to XMR swap

Whatever the route, the all-in cost decomposes into four legs. One: the BTC network fee to fund the swap — mempool-dependent, identical across routes. Two: the route’s own take. RFQ desks price theirs into the quote as spread, and a fixed-rate quote costs more than a floating one because the desk is selling you its price risk. Pool-based corridors charge a liquidity fee that grows with your size relative to pool depth, plus an outbound fee. Haveno charges explicit trade fees, and you also carry the capital cost of XMR locked as deposit for the life of the trade. Atomic swap makers simply quote their spread. Three: the XMR outbound network fee, which is negligible. Four: the gap between the rate you were quoted and the rate that settles — on floating quotes and thin pools this is often the largest and least visible leg. That last leg is where a guaranteed minimum received matters most: the settlement floor should be known before the BTC leaves your wallet.

FAQ

What is the fastest way to swap BTC to XMR?

An instant-exchange (RFQ) desk. You send BTC to a deposit address and receive XMR in minutes after confirmation, with no account. The trade-off is that the desk holds your funds while the swap is in flight, so counterparty risk is concentrated in that window.

Can I swap BTC to XMR without an account?

Yes. Instant-exchange desks, Haveno-based P2P networks, and atomic swaps all work without registration. No account is not the same as no obligation: you remain responsible for local law and tax reporting wherever you trade.

Does THORChain support Monero?

Nearly. As of mid-July 2026 THORChain's native XMR integration has cleared end-to-end testing and the team has flagged mainnet launch as imminent, following the June 23 restart after the May exploit. Check live status before routing size through it.

Do Maya Protocol or Chainflip support XMR?

No. As of mid-2026 Maya Protocol runs no native XMR pool (its privacy-asset corridors are Zcash and Dash), and Chainflip supports Bitcoin, Ethereum, and Solana assets with no announced Monero support.

What is the most trustless way to swap BTC to XMR?

A BTC to XMR atomic swap. No third party touches the funds at any point; the trade either completes or refunds through timelocks. The cost is thin maker liquidity, small trade sizes, and the need to stay online until the swap resolves.

The TT desk thoughts

This is the one corridor where the custody model is not a detail — it is the trade. Someone converting BTC to XMR is, by definition, paying for self-sovereign financial privacy, and routing that trade through a custodial desk is a structural contradiction that users tolerate purely for convenience. The eXch seizure made the tail risk concrete: when a custodial swap desk goes down, whatever was in flight goes with it. Our default remains boring: RFQ desks for small clips where speed matters, Haveno or an atomic swap when the size or the principle justifies the friction — and never more in flight with any single desk than you would leave on a small exchange overnight.

The forward-looking read is THORChain. If the corridor ships and holds, pool-based pricing does to this pair what it did elsewhere: it compresses RFQ spreads and forces the custodial desks to compete on service rather than scarcity. But a corridor that launches weeks after a $10.7M exploit and a 39-day halt has to earn trust the slow way. We would watch it for a few weeks of uneventful settlement before it earns a place in the rotation — new plumbing gets probed hardest right after it is laid.
