Your tax tool calculates it. But can you prove it?
Auditors want evidence, not summaries. The gap between a report and proof is where compliance fails.
01
Transaction history is fragmented
Screenshots aren't primary evidence — auditors need traceable, blockchain-sourced records.
02
Reports can be assembled from anywhere
There's no proof they're blockchain-sourced. Anyone can produce a spreadsheet.
03
Wallet ownership is declared, not verified
Anyone can claim any address. Cryptographic proof is the only way to verify control.
