What it does

Satzo estimates UK capital gains on crypto using Section 104 pooling with the same-day and 30-day matching rules, across Bitcoin, Ethereum and Solana wallets.

It also combines every wallet and DeFi position you add into one portfolio total, with history rebuilt from transactions rather than daily snapshots.
