# Kryptos

> Kryptos is crypto financial data infrastructure: a back office for crypto businesses (accounting, reconciliation, treasury, audit-ready reporting), CARF and DAC8 reporting for crypto-asset service providers, the Kryptos Connect API for crypto data, and crypto tax and portfolio software for individuals and accountants in 35+ countries. Built by Kryptoskatt AB, founded in 2022 and headquartered in Sweden. SOC 1 and SOC 2 Type II audited, ISO/IEC 27001:2022 certified, read-only by design.

Kryptos serves four audiences from one data layer covering 5,500+ integrations (150+ blockchains, 100+ exchanges, 50+ wallets):

- **Crypto businesses and finance teams** (exchanges, funds, foundations, DAOs, protocols): multi-entity treasury, on-chain to off-chain reconciliation, GL-ready journal entries, GAAP and IFRS reporting, audit trails for SOX and ISAE 3402, crypto invoicing, SAFT and token-vesting tracking.
- **Crypto-asset service providers with reporting duties** (exchanges, custodians, brokers, dealers): CARF and DAC8 reporting, covering reportable-user detection, self-certification and TIN validation, gains and thresholds, OECD CARF XML and national formats such as Sweden's KU94. Also withholding at source such as Austria's KESt, US Form 1099-DA, and a white-label tax centre so the provider's own users can file from the same data.
- **Developers and product teams**: Kryptos Connect, one API for normalised, classified wallet, exchange and on-chain data, plus an MCP server so your own tools and AI agents work inside the permissions you grant. Free tier of 10,000 requests per month.
- **Individuals and accountants**: crypto tax reports for 35+ countries (Form 8949 and Schedule D in the US, SA108 in the UK, Anlage SO in Germany, K4 in Sweden), portfolio tracking, DeFi and NFT support, and multi-client workspaces for accounting firms. Free up to 100 transactions per tax year.
