Kryptos tracks cost basis per token across mints, secondary buys, transfers, and gifts. Royalties, marketplace fees, and gas costs handled the way each jurisdiction expects.
OpenSea, Blur, Magic Eden, Tensor and 100+ marketplaces.

Most tax software treats NFTs like fungible tokens. We don't. Each tokenId has its own basis, history, and tax fate.
Browse every NFT you've ever held, with current floor price and where it sits today.
Mint vs secondary, gas vs price, royalty paid. Each component recorded so future sales calculate correctly.
Daily floor prices for every collection, so unrealised P&L is honest, not made up.
OpenSea, Blur, Magic Eden, Tensor, and the long tail of niche marketplaces.
Each jurisdiction's quirks (collectibles rate in the US, art VAT in the EU) handled per country.
Free mints, airdrops, and giveaways tracked at FMV at receipt. Sales calculated correctly years later.
Hundreds of NFTs across years. Kryptos reconstructs cost basis even on wallets that predate the app.
Daily trades on Blur, royalty optimisation, blue-chip exits. We track every event without choking on volume.
Mint income vs royalty income, marketplace fees, secondary sale royalties, all categorised for income tax.
F-NFTs and shared-vault NFTs handled with the correct basis attribution per holder.

Every wallet, every chain. Floor price, current holder, acquisition cost, and full transaction history for every tokenId.
Gas, mint price, marketplace fees, royalties, each recorded at the event so the sale calculates correctly.
Per-NFT gain/loss, ordinary income from creator royalties, and country-specific treatment, in one view.
In most jurisdictions, paying gas + price to mint is not a sale; the mint cost becomes your basis. Selling later is the taxable event. A few jurisdictions treat the mint payment in a specific token (e.g. paying in ETH) as a disposal of that ETH; we apply the local rule.
Royalty paid by a buyer reduces their basis (or adds to cost). Royalty received by a creator is income. Both flows are tracked separately and labelled.
We detect wash patterns (same wallet on both sides, same NFT within 30 days) and surface them for review. You can choose how to treat them depending on your jurisdiction's wash-sale rules.
Yes. Magic Eden, Tensor, Hadeswap, and the rest. Same cost-basis logic per tokenId.
NFTs appear in your standard tax report. You can also download an NFT-only export if your accountant wants to see them separately.
