Recently, I’ve been overwhelmed by transaction record reconciliation, and I suddenly realize: tax matters really can’t be handled with a quick fix at the end of the year. My simple method is to start “keeping evidence” now: every deposit, withdrawal, token swap, and contract opening/closing, I put the CSV exported from the exchange along with the corresponding on-chain hash into the same folder, and package them monthly; I also add an extra column “Purpose of this transaction” (transfer/arbitrage/market making/repayment), otherwise I won’t recognize my own transactions in a few months.

By the way, these past couple of days, before and after the main chain upgrade, everyone in the group was guessing whether projects would migrate. I instead took the opportunity to mark cross-chain/bridge records separately: I’m most worried about reconciling at the end of the year with a bunch of chain hops back and forth, where the cost basis and destination don’t match. Anyway, I don’t aim to do extra work; just ensuring the data is complete and can be reviewed gives me peace of mind.
