The data stack for audit, tax, and financial reconciliation
Turn raw onchain activity into the normalized, source-traceable records your accountants need to produce journal entries, file taxes, and sign off on reconciliations.
What audit and tax teams use Dune for
Accounting
Build wallet-level activity views, fee lines, and token flows from decoded events instead of reconciling screenshots and exchange CSVs by hand.
Reconciliation
Match internal ledgers to onchain transfers, bridge movements, and known exchange patterns across the networks your clients actually use.
Proof of reserves
Pull balance snapshots at a specific block or timestamp and tie asset lines back to verifiable chain state for attestations and third-party review.
Staking income tracking
Track validator rewards, liquid-staking yield, and withdrawals with timestamps so income schedules stay consistent across tax periods.
Transaction history export
Export full histories and curated cuts to CSV or your warehouse so workpapers and filings stay in the tools your firm already runs.
The data catalog for onchain accounting
Every dataset your team needs — token transfers, decoded logs, entity labels, stablecoin flows, and staking income — normalized, source-traceable, and ready to query. Built for the workflows that end in a filing, not just a dashboard.
