What it does

  • UK capital gains estimates

    Section 104 pooling with the same-day and 30-day matching rules.

  • Bitcoin, Ethereum and Solana

    Add wallets by address and Satzo reads the balances on each supported network.

  • One portfolio total

    Every wallet and DeFi position in one number, with history rebuilt from transactions.

Changelog

I build and run all of it: the CGT rules, wallet integrations, reporting and hosting.
