What happens if I only saved the swap link but not the transaction ID

07 September 2026

You can still access the swap record for a short time using the link, but the link will eventually expire or break. After that point, you lose the ability to prove the swap occurred through that platform alone.

The swap link works because the platform stores a temporary record tied to a unique URL. When you complete a swap on the exchanger, it generates a confirmation page with that link. The link contains an identifier the platform uses to look up your order in its database. As long as the platform keeps that record active, the link will load a page showing the swap details: amounts, the receiving address, the transaction hashes on each chain, and a timestamp.

But that record is not permanent. Non-trading/p2p-platform-freezes-funds/">custodial platforms typically do not store swap data indefinitely. Their business model depends on processing swaps, not archiving them. Disk space costs money, and old records get purged after a set period. Some platforms delete the data after 30 days. Others keep it for 90 days. A few hold it for a year. None guarantee lifetime storage. Once purged, the link returns a "not found" or "expired" page.

The transaction ID is different. That hash lives on the blockchain permanently. Anyone can look it up on any block explorer at any time, years later. The link points to a temporary server. The hash points to an immutable ledger. One is a paper receipt that gets shredded. The other is carved in stone.

If you still have the link and it still works, act immediately. Open the page. Copy every detail you see. The most important piece is the transaction hash for each blockchain involved in the swap. Write those down. Take a screenshot of the page that shows the hashes. Save the whole page as a PDF if the browser lets you. Do not assume you will come back tomorrow. Tomorrow the link might be dead.

If the link is already dead, you have fewer options. You can try to reconstruct the swap from your own records. Check your wallet history for outgoing and incoming transactions around the time you remember swapping. Match the amounts against what you recall. That gives you the transaction hashes on the sending and receiving chains, but you lose the proof that two chains were linked by one swap. A tax auditor or a dispute resolver sees two independent transactions. You cannot prove they were the same trade.

The hub page, "Proof you swapped for your tax trail," explains why that distinction matters. Without the link between chains, you have two separate events. Tax treatment for a swap differs from two unrelated transfers. A dispute over a failed swap becomes impossible to resolve if you cannot show the platform accepted your order.

The practical takeaway is simple. Save the transaction IDs the moment you complete a swap. Do not rely on the swap link as your only record. Treat the link as a temporary convenience, not a permanent archive. If you only have the link, check it now. If it works, copy everything. If it does not, start digging through your wallet history while your memory is still fresh. The longer you wait, the harder it gets.
