Every year by the end of the year, I want to chop off my own hand for randomly swapping back then... To put it plainly, the most annoying part of taxes/declarations isn’t calculating the tax—it’s that you can’t retrieve the complete transaction records in the first place. My approach is pretty crude: every time I have large amounts of on-chain interactions (especially the kind where an AI Agent automatically runs orders), I casually dump the txhash, wallet addresses, the route/router or contract names I used, and the screenshots from that time (including the timestamps and slippage settings) into the same folder. Then I export a report weekly—both the exchange statement and the on-chain details—so I don’t wait until December to fill in the gaps. One more thing: the more “effortless” the automated trading is, the easier it is to miss those few transactions—things like overlooked authorizations, failed trades, or the ones that get sniped/filtered out. In the end, reconciliation turns into a disaster. That’s it for now—I'd rather spend 5 extra minutes during ordinary days.
