# LedgerLens > LedgerLens is digital asset audit and attestation software, purpose-built for auditors and accountants. It lets audit and accounting firms verify on-chain balances, prove wallet ownership, run Proof of Reserves engagements, and export standardized, audit-ready evidence for their workpapers across 30+ blockchains. LedgerLens is built by The Network Firm (TNF Tech & Services, LLC). The product centers on the Auditor's Workbench (historical balances, transaction testing, ownership verification) and three Proof of Reserves toolkits (Merkle Tree, On-Chain, and Real-Time / continuous CPA examinations). The site is a static marketing site; the application lives at app.ledgerlens.io.
