What a swap provider sees about you and how that affects getting your money back

05 September 2026

A swap provider sees only the data you voluntarily give it and the blockchain addresses involved in your transaction. That visibility is narrow, and it directly shapes your options for recovering funds if something goes wrong.

Here is the specific information a typical non-custodial swap provider holds about you: your deposit address, your receiving address, the transaction hash from your wallet, the amount and asset you sent, and any email address you supplied during the order. That is it. They do not see your name, your location, your IP address (unless they log it, which some do and some do not), or what you do with the coins after the swap. Most providers operate without requiring registration or KYC for smaller trades, so the link between you and the transaction is the addresses alone.

This limited view matters most when you need a refund. If you sent funds to the crypto-wrong-address-irreversible/">wrong address, or the swap failed and the provider says the transaction was complete, you are asking them to reverse or alter a blockchain transaction. They cannot do that. The blockchain is immutable. What they can do is manually initiate a new outgoing transaction to return your coins - but only if they can confidently identify you as the sender.

The problem is that anyone who knows your deposit address could claim to be you. Without a login, a verified identity, or a persistent account, the provider has no way to distinguish the real sender from an impostor. So they rely on what you alone know: the exact transaction hash, the deposit amount, the receiving address, and any order ID the site generated. If you cannot produce those, they have no reason to act. If you can, they may refund you - but only if their policy allows it and if the coins are still in their wallet.

This is why the set of pages under "Swapping crypto safely" stresses confirming a provider's on-chain reputation before you send funds. A provider that has a track record of honoring refund requests will have transparent wallet addresses and a published process for contacting support. A provider that buries its support contact or uses shared liquidity addresses with no clear ownership is harder to hold accountable.

Your leverage is minimal. The provider holds your coins until they process the swap or a refund. If they decide not to refund you - because their terms exclude your error, because they claim the swap completed correctly, or because they simply disappear - you have no court to appeal to and no bank to charge back. The blockchain does not care about mistakes.

That is not an argument against using swap services. It is an argument for verifying first. Check the provider's wallet activity, read its terms about refunds, and understand that the only proof you are the sender is the hash in your wallet. Keep that hash. Keep the order ID. Without them, you are a stranger asking for money back from someone who has no reason to trust you.
