Swapping XMR
What a swap is, how atomic swaps work, the difference between custodial and non-custodial services, and the risks to understand first.

What is a swap?
A swap exchanges one cryptocurrency for another, for example Bitcoin (BTC) for Monero (XMR). It can happen on an exchange, through a swap service, or directly between two people using an atomic swap.
Atomic swaps (BTC ⇄ XMR)
An atomic swap is a trade between two parties enforced by cryptography instead of a middleman. Either both sides receive their coins, or the swap is cancelled and both get their funds back (after a timeout). Nobody else holds the money in between.
BTC–XMR atomic swaps are possible thanks to research by the Monero and Bitcoin communities; an example of open-source software is the xmr-btc-swap project. Atomic swaps can be slower and more technical than other routes, and you still need a counterparty willing to trade.
Centralized vs non-custodial services
Centralized exchanges
You deposit funds into an account the exchange controls. Usually require identity verification (KYC). Convenient, but you depend on the exchange: it can freeze accounts, get hacked or go bankrupt.
Instant swap services
You send coins and receive another coin at an address you give. No account, but during the swap the service holds your funds, and it can delay or refuse a swap, for example for compliance checks.
Non-custodial / atomic
No third party holds your funds. More control, but more responsibility: you have to run the software correctly and keep it online until the swap finishes.
Risks
- Scams and fake sites. Phishing sites copy real services, and fake “support” asks for your seed phrase. No real service needs your seed phrase.
- Fees and spreads. The total cost includes the exchange rate margin and network fees, not just the advertised fee. Compare the final amount you receive.
- Regulation. Rules for crypto services are tightening, including the EU's MiCA framework and anti-money-laundering rules that restrict privacy coins on regulated platforms. What is allowed depends on where you live.
- KYC and frozen funds. Services may ask for identity documents or hold a swap for review, even if they did not say so at first.
- Irreversibility. A wrong address or wrong network means the coins are usually gone for good.
Tips
- Start with a small test amount.
- Type or bookmark URLs yourself; don't click links from ads, DMs or search ads.
- Double-check the receiving address and the network before you send.
- Read a service's terms, including when it may ask for KYC or hold funds.
- Keep records for your taxes.
- Never share your seed phrase or private keys with anyone.
