Our take
Arkham
Arkham delivers a specialized approach to blockchain analytics, combining entity-level address attribution with direct portfolio tracking and transaction visualization. Rather than operating as a conventional accounting ledger or custodial financial intermediary, the platform aggregates public on-chain activity across multiple networks into structured entity profiles. Operators can inspect token balances, historical counterparty links, and smart contract executions through customizable dashboards and automated alerts. The web interface provides substantial investigative utility without demanding private keys or account custody. However, users should treat proprietary identity clustering as analytical intelligence rather than definitive legal proof. While the core visual platform provides robust open access, organizations seeking high-frequency data integration must negotiate dedicated enterprise agreements. Overall, Arkham represents a powerful investigative tool for monitoring market participants and complex asset flows.
Divly
Divly delivers a focused cryptocurrency tax calculation engine designed to eliminate the friction of regional tax compliance across European jurisdictions. Headquartered in Sweden and operating since 2021, the service distinguishes itself by supporting specific domestic tax reporting formats, such as Sweden Skatteverket K4 forms, alongside localized outputs for Norway, Finland, Denmark, Germany, and the United Kingdom. Instead of relying purely on generic capital gains summaries, the platform maps taxable dispositions, mining rewards, staking yields, and gifts to precise regional tax code definitions.
The system operates on an entirely non-custodial basis, using read-only API keys and standard spreadsheet imports to reconstruct portfolio histories. While active traders with hundreds of thousands of decentralized finance trades may hit tier constraints or need manual mapping adjustments, Divly provides a streamlined workflow for Nordic and European investors seeking compliant, localized annual filings.
