To be honest, the most reliable thing about transaction records is still the habit of keeping them conveniently. Each week, or after each withdrawal, I just quickly note the tx hash, the time, and the receiving address. No need to make it complicated—just a txt file is enough. In any case, organizing it at year-end is much more comfortable than digging through your wallet.

A few days ago, when that cross-chain bridge incident happened, a lot of people waited for confirmations until they were almost losing their mind. At that time, I went back to check my own records from a few years ago, and it turns out some on-chain finality wasn’t very reliable. Even when the confirmation count was reached, it still wasn’t necessarily solid. So when I record transactions now, I generally write down the block height of the final confirmation clearly—not just count a few confirmations and call it done. It’s more tedious, but it saves a lot of trouble when tax season comes around.

That’s it for now. I can’t be bothered to set up overly complex tools—keeping track of the in-and-out direction and the time is enough.
