OPSFI
Bookkeeping & Accounting
Accurate, audit-ready books — fiat and on-chain.
Our Position
Most firms can keep books. Few can keep them on-chain.
Clean books are the foundation everything else is built on — the close, the reporting, the raise, the audit. We own that foundation end to end, with the rigour of an in-house controller and none of the overhead.
And where most accountants stop at the bank feed, we keep going. As native blockchain accountants, we reconcile wallets, exchanges and DeFi activity across any chain into the same clean, GAAP-aligned ledger — so your fiat and your crypto finally live in one set of books.
Our Capabilities
Books you never have to question.
Four capabilities. One senior team. Select any to see exactly what's included.
Our Approach
How We Work
Discovery
We review your current books, systems and transaction volume — across fiat and on-chain — to scope the work precisely before recommending anything.
Clean-up & Setup
We bring historicals current, structure your chart of accounts, and connect the banks, wallets, exchanges and tools your books depend on.
Monthly Close
Every period we categorise, reconcile and close — fiat and on-chain — then deliver GAAP-aligned statements and reporting on a fixed cadence.
Ongoing Delivery
Clean books, a reliable close, and reporting your team, board and auditors can rely on — consistently, month after month.
Get Started
Clean books. On time. On every chain.
Whether your transactions live in a bank account, a wallet, or both — your books should be audit-ready every month. Let's talk about owning yours.
