What Taxinger reads
The networks, the protocols and the countries covered today. A network is added when every user's history on it can be read in full: see adding a chain or a protocol.
Networks
Read with balances proven against the chain (the native coin and the tokens your transactions have named): Ethereum, Arbitrum One, Base, OP Mainnet, Polygon PoS, BNB Smart Chain, Avalanche C-Chain, World Chain, Robinhood Chain, Monad, HyperEVM, and Arc.
Read in full, the balance proof still to come: Solana, Bitcoin, Zcash, Litecoin, Dogecoin, Bitcoin Cash, Dash, and Cardano.
Zcash is read on its transparent side (t1…, t3…): what the shielded pool holds is readable only inside the wallet that owns it. Value crossing into that pool, or coming out of it, is listed among the things a year leaves out until they are answered.
One address is read on every network where it can exist, so an address used on several of them is one address in your wallet, not one per network.
Protocols
These are read natively, with their actions named for what they are: Uniswap, Aave, Curve, Pendle, Morpho, 1inch, Jupiter, Raydium, Orca, Meteora, Marinade, CoW Swap, Stargate, Across, Circle CCTP, Synapse, Compound, SushiSwap, Beefy, Lyra, Perpetual Protocol, Maple, Clearpool, Platypus, and Treasure.
Beyond them, a fork that logs the same events as Uniswap, Curve, Aave v3 or Compound, and any vault on the ERC-4626 standard, is read with no work on your side: the standard is what is recognised, not the brand.
Prediction markets: Polymarket, Limitless, Predict.fun, Opinion, and Probable. A share, its outcome and the result are read, with the rewards, yield and rebates those markets pay.
Exchanges
Every exchange whose statement you can download: the file is read into the same history as your wallets' transactions. See exchange statements.
Countries
Taxes are computed for Austria, Germany, Spain, United Kingdom, Greece, Italy, Japan, Poland, and Portugal, each from its own statutes. What every one of them answers (what is taxed, at what rate, on which form, when the return is due) is on its own page under Country guides.
A contract nothing interprets
When a transaction touches a contract nothing interprets, what moved is still read from the transaction itself: the transfers, the internal transfers, the fee, and what the call said it was doing. What is still unclear after that is listed as unclear.
An unknown protocol leaves you a question to answer, and what it touched stays out of the totals until you do.
