Which swap details should I copy before I close the browser tab

07 September 2026

Copy three things before you close the tab: the transaction hash (TXID), the exact amounts of each token swapped, and the timestamp. Those three items are the minimum you need to reconstruct the swap later. Without them, you rely on memory or external tools that may not keep your history forever.

The transaction hash is the most important piece. It is a long string of letters and numbers that uniquely identifies the swap on the blockchain. Every Tron transaction gets a hash. You can paste it into a block explorer later and see every detail the network recorded: sender address, receiver address, token amounts, fees, and the block it was included in. The hash is your receipt. Write it down, copy it to a text file, or paste it into a spreadsheet. If you lose the hash, you can still find the transaction by scanning your wallet address through a block explorer, but that becomes tedious if you swap frequently.

The exact amounts matter because the swap page shows a net result after the exchanger's fee and any slippage that occurred. The blockchain records the final amounts that left your wallet and arrived in it. Your tax or accounting software will need those numbers. Slippage can change the rate by a fraction of a percent between when you hit confirm and when the transaction lands. Copy the "you received" number, not the estimate you saw before confirming.

The timestamp helps you match the swap to your own records. Exchange APIs, wallet logs, and block explorers all use different time zones or formats. Having your own timestamp - ideally in UTC - lets you cross-reference quickly. If you trade manually, note the date and time in your time zone alongside the TXID.

Also copy the smart contract addresses for the tokens involved. Swaps on Tron often use TRC-20 tokens, and different projects can share similar ticker symbols. "USDT" on Tron is not the same contract as "USDT" on Ethereum. The contract address is the definitive identifier. You can get it from the swap page's token selector or from the transaction details on a block explorer after the swap completes.

Do not assume your browser history will save everything. Browser caches clear. Private tabs vanish. Cookies expire. If you rely on the open tab as your only record, you lose the swap details when you close it. Copy the information immediately after the swap confirms, before you navigate to another page or shut down your computer.

The hub page under which this advice sits - "What swap records to keep for tax time on Tron" - explains how to organize these pieces into a permanent file. That page covers the difference between a simple list of TXIDs and a structured log that includes cost basis, wallet addresses, and dates. It also addresses what to do if you never copied anything and need to recover records from the blockchain after the fact. That is the next page to read if you want to build a system rather than just grab the essentials once.

One more detail: if you swapped through a service that uses an intermediary address (a so-called "forwarder" or "router"), the transaction hash might show the router's address as the sender or receiver, not yours. That is normal. The block explorer still shows your address in the internal calls or in the event logs. Copy the TXID anyway. The block explorer will reveal the full path when you look it up.

Finally, check that the swap actually completed before you close the tab. Some swap pages show a confirmation animation but the transaction fails silently on the network. Wait until you see the TXID and a "success" status. If the swap failed, copy the failed transaction hash too. Failed transactions still incur network fees. You need that record for your tax calculations.

Close the tab only after you have saved the TXID, the amounts, the timestamp, and the token contract addresses. That takes thirty seconds. Losing them costs more time later.
