Finality turns your crypto history into tax figures you can check. Connect your wallets and exchange exports, and Finality reconciles every trade, swap and transfer across chains and venues, matching each sale back to what you paid for it so costs are not lost between wallets. Then just ask ChatGPT: what's my capital gains position for this tax year, what did the reconciliation find and what is each finding worth, what was I still holding at the end of the year. Answers come from your own Finality account, with the figures and the working behind them. When a year is ready, Finality produces the working paper for your return (HMRC's SA108 in the UK, IRS Form 8949 in the US) and an evidence workbook for your records. Connecting is read-only by default; choose Full automation to let ChatGPT add wallets and start scans for you. It can never delete your account, change your sign-in or see exchange passwords.
