Chainrule
Crypto accounting for companies

Crypto accounting that matches the chain. Exactly.

Chainrule turns your wallets, exchange accounts and DeFi positions into books you can reconcile line by line: every balance matched to the blockchain to the last unit, gains in your functional currency, and journals posted straight into Xero or QuickBooks.

One rule, no exceptions

Chainrule compares balances in exact base units — wei, satoshis, lamports — never rounded figures. Nothing is plugged or estimated to make the numbers fit: if something is missing, the gap stays visible until it is explained.

Everything a finance team needs from its crypto

From the first transaction to the posted journal, in one place.

Every chain, every token

Wallets synced from authoritative on-chain sources, identified by contract — never by name. Scam airdrops are filtered out automatically.

Exchange accounts

Exchange balances reconciled per account and asset against the exchange itself, with read-only API keys.

DeFi positions

Liquidity pools, lending and borrowing, staking and vaults — Uniswap, Aave, Aerodrome, Kamino, Jupiter, Orca, Minswap, Indigo and more — detected and valued, including at past month-ends.

Tokenized real-world assets

Tokenized T-bill funds, gold and stocks valued at their official NAV — never a trading price — with their IFRS classification and period-end journals.

Gains in your currency

FIFO cost per company in your functional currency, transfers between your own wallets at cost, and policies for your own token.

Straight into your ERP

Journals posted to Xero or QuickBooks per legal entity, mapped to your own chart of accounts. Issue paid sales invoices straight from crypto receipts.

ERP reconciliation

Chainrule's balances compared with your ledger, account by account, so differences surface before the close.

Exposure dashboard

Holdings over the last twelve month-ends by category, market risk and time to cash — with your own token shown apart.

Any date, any period

Historical balances at any date, with USD and functional-currency values, exportable to CSV, Excel and PDF.

How it works

Three steps from wallets to a closed month.

  1. Connect

    Add your wallet addresses and read-only exchange keys, and connect each entity to its Xero or QuickBooks organisation.

  2. Reconcile and value

    Chainrule syncs every transaction, matches each balance to the chain exactly, classifies, prices and computes gains.

  3. Review and post

    Check what Chainrule prepared, then post the journals to your ERP. Posted entries are never changed afterwards.

Built for auditable books

Controls that keep the numbers — and your access — trustworthy.

  • Read-only by design. Wallet addresses and read-only exchange keys: Chainrule cannot move your funds.
  • Your data stays yours. Each company sees only its own data, enforced in the database itself.
  • Credentials never reach the browser. Exchange keys are readable by the server only.
  • Posted means final. An entry posted to your ERP is never rewritten or deleted by a later sync.
  • No silent gaps. A provider that throttles is retried, never skipped; a missing transaction shows as a gap.
  • Your own ERP login. Each entity connects with its own Xero or QuickBooks account.
