Your history imports, and proves itself.
Whichever tax app holds your history today, its export imports here one to one, with the row count reconciled on screen and every refused row explained. Beyond the four big apps, the importer reads Coinbase, Kraken and Binance statements, any plain CSV, scans Bitcoin and six EVM chains on-chain, and syncs Kraken and Binance with read-only keys.
