What swap records does a non-custodial platform keep and can I request them

07 September 2026

Non-trading/p2p-platform-freezes-funds/">custodial platforms do not keep any records that identify you personally, and you cannot request records from them because they have nothing to link to your identity. The platform never holds your funds or knows who you are, so the only proof of a swap lives on your side of the transaction.

Non-custodial means the platform never takes custody of your coins. You send tokens to a smart contract or directly to another user, and the platform merely facilitates the route. It does not know your name, your IP address, or your wallet address if you use the exchanger through a privacy-preserving interface. Some platforms do log technical data - timestamps, amounts swapped, and the blockchain addresses involved - but they store that data without any identifier they can connect to you. If you lose your own records, the platform cannot help you reconstruct a swap because it does not know which log entry belongs to you.

The records a non-custodial platform typically keeps are: the source and destination blockchain addresses, the token amounts, the transaction hashes on both chains, and a timestamp. These entries are stored for operational reasons - to track liquidity, detect abuse, or debug failures. The platform may retain them for a period, often between 30 days and a year, then delete them. You cannot request your specific records because the platform has no way to match you to an entry. Even if you provide your wallet address, the platform cannot confirm that address belongs to you. Anyone could claim any address.

Some platforms offer a "swap status" page where you can look up a transaction by its hash. That page shows the same data the platform logged. If you still have the hash, you can retrieve the record yourself without asking anyone. If you lost the hash, the platform cannot help you find it. The blockchain itself is the only permanent record.

You can request records from a non-custodial platform, but the answer will be that they have no records tied to you. The platform may comply with a legal request from authorities if required by law, and in that case it would hand over whatever logs it has. Those logs still contain no personal data unless you sent your email address or other identifying information during the swap. Most non-trading/p2p-platform-freezes-funds/">custodial platforms do not ask for an email address. Some do, for notifications, but that is optional and stored separately from the swap log.

The practical takeaway: you are the only person who can prove your swap ever happened. The platform cannot verify your identity later, and it will not hold a copy of your receipt. That is why the hub page "Proof you swapped for your tax trail" exists. You must save your own evidence from the moment you swap, because nobody else can produce it for you.

If you want to test what a platform retains, complete a small swap and immediately check what data appears on the swap status page. That is the full extent of what exists. Save that page as a PDF or screenshot. After the platform deletes its logs, the data is gone from their side. The blockchain retains the transactions permanently, but without your hash you cannot find them among millions of others.

Non-custodial platforms are designed to minimize trust. They trust you to keep your own records. That design also means they cannot rescue you from your own forgetfulness. Requesting records from them is possible in theory, but useless in practice, because the records they keep do not name you.
