Yes. DGFiP treats most crypto disposals as taxable events: selling for fiat, swapping one coin for another, spending on goods, or earning yield. Capital-gains rules apply to trading; income rules apply to staking, mining, and airdrops. The exact rate depends on your holding period and bracket.
DGFiP considers these taxable: disposing crypto for fiat or another crypto, spending crypto on goods or services, receiving staking or mining rewards, getting airdrops, and earning DeFi yield. Transfers between your own wallets aren't taxable. Kryptos auto-classifies each transaction and applies the right treatment.
For France returns, Kryptos generates form2042, form2086, and form3916. We export them as PDF for record-keeping, CSV for accountants, and tax-software-compatible files where supported. Every line traces back to the source transaction so DGFiP questions are answered by your audit trail.
Yes. We support 150+ blockchains and 5,500+ integrations (across DeFi, CEX, wallets, NFTs and on-chain like Uniswap, Aave, Lido, and Curve, plus the major NFT marketplaces). Each is mapped to the right DGFiP treatment: LP-token cost basis, NFT mint and sale events, staking-reward income, governance distributions, perpetual funding rates.
Every transaction Kryptos classifies has an audit trail back to the source: the cost-basis method applied, the exact disposal sequence, and the on-chain or exchange reference for each line. SOC 2 Type II certified means our controls are independently verified. Most clarification requests resolve from the report itself.
Kryptos Connect is the API behind Kryptos itself. One call gets you reconciled balances, tax-aware cost basis, and clean transactions across 5,500+ integrations. Embed it in your fintech, accounting product, or wallet.
