GENERAL LEDGER Balance is enforced, not checked.

Double-entry rules live in the database. An unbalanced entry is rejected at write, by any client, human or agent.

→Σ debits = Σ credits, enforced at the data layer

→Posted lines are append-only with permanent lineage

→Closed periods lock cryptographically

No app-layer flag to bypass, the constraint lives where the data lives.

MONTH-END CLOSE Close the month in one run.

One guarded run posts depreciation, amortization, revenue recognition, and FX revaluation, then refuses to close until the trial balance ties.

→Durable checklist with real sign-offs

→Readiness gate blocks an out-of-balance close

→Period locks on close; reopening is privileged

DIGITAL ASSETS Crypto on the same books as your dollars.

Tokens are first-class: every lot carries cost basis, every movement posts a balanced entry, and the subledger ties to the GL continuously.

→Lot-by-lot basis and realized gains

→Fair value at close, unrealized to P&L (ASU 2023-08)

No side spreadsheet. Nothing to reconcile at month-end.

REPORTS Statements derived from the journal.

P&L, balance sheet, cash flow, trial balance, and aging, all computed from journal lines, so they reconcile by construction.

→Comparative P&L and balance sheet with prior-year Δ

→Cash flow, indirect and tie-checked

AI AGENTS Agents draft. A human approves.

Chartered agents categorize, reconcile, and prepare the close, as drafts. Nothing reaches the ledger without human approval. That's enforced, not optional.

→Bookkeeper, Close Controller, Tax Strategist, Treasurer

→Every run is logged, metered, and reversible

→Agents never auto-post to the ledger

SEALED · ON-CHAIN PROOF

We seal your ledger to Ethereum. Not your coins. Your proof.

We hash your whole journal into one SHA-256 fingerprint on Ethereum mainnet. Your coins stay where they are. The proof of how you accounted for them goes on-chain.

Seals the books, not the coins

Crypto stays on its own chains. The anchor fingerprints the ledger that accounts for it, so the record can't be quietly changed.

Tamper-evident by math.

Verified by anyone, trusting no one

An auditor recomputes the fingerprint and reads it off the public contract. A match proves the books are untouched since close.

Zero trust required.

Anchored to Ethereum mainnet

The most secure public ledger there is, through a contract with no admin keys. One checkpoint per close.

Permanent. Public. Provable.

WHAT'S INSIDE

Everything on one ledger.

Every module posts to the same core. No syncs, no cron jobs, no migration lag.

TRUST & SECURITY

Books don't drift. That's not a promise. It's a constraint.

The invariants are enforced where the data lives, not in the app. An unbalanced entry can't be written. A posted entry can't be silently changed. When your auditor asks how you know the numbers are right, you have an answer.

-- enforced in the database, not just the app
INVARIANT sum(debits) = sum(credits) · every posting
INVARIANT posted entries are immutable · append-only
INVARIANT entry_date within its period · no out-of-range dates
INVARIANT closed periods stay closed · reopen is privileged

Double-entry invariantsEvery posting balances, rejected at write, not flagged after.

Immutable, audit-logged historyPosted entries never change; every action leaves an append-only trail.

Real roles, real boundariesOwner, admin, controller, clerk, auditor read-only. Least privilege by default.

Every entry dated in its periodPostings can't fall outside their period, and a closed period only reopens through a locked, privileged path.

Encrypted at rest, verified identityEmail + SMS verification, bank-grade session handling, encryption at rest.
