I used to be really casual about trading, doing cross-chain transfers, grabbing incentives, mining, and selling all at once, thinking that everything on the chain was just there, and I’d deal with it at the end of the year.

As a result, during the reporting season, I was completely confused: the same bridge transfer was split into fragments across different chains and wallets, with small, high-frequency gas fees, and the more I looked into it, the more annoyed I got.

Now I just play it straight: every time I do a cross-chain transfer, I casually drop the transaction hash and a screenshot into a fixed folder, and add a note like “why transfer, from where to where.”
If it’s a new L2 incentive, I’ll create a small separate table to at least keep track of deposit and withdrawal times, token swaps, and bridge transactions clearly.
Honestly, I don’t aim for perfect retrospection; I just want to ensure I can match the on-chain evidence later… otherwise, I’d just be torturing myself.
