What is a crypto sub-ledger?

A crypto sub-ledger is a subsidiary ledger that holds the transaction-level detail of your crypto activity, calculates cost basis and gains, and posts summarized journal entries to your general ledger. It's the same idea as an accounts-receivable or fixed-asset sub-ledger — a specialised system that does the detailed work, then feeds your books clean.

Why crypto needs its own sub-ledger

General ledgers and ERPs were never built to track wallets, tokens, and cost basis across thousands of on-chain and exchange transactions. Trying to do it directly clutters the GL with raw activity, breaks down on cost basis, and leaves no defensible trail. A sub-ledger solves that by sitting in front of the GL:

1. It ingests every transaction from your exchanges and wallets,
2. classifies each one and calculates cost basis and realized gains,
3. summarizes the activity into journal entries, and
4. posts those entries to your general ledger.

Your GL stays the system of record; the detail lives in the sub-ledger, where you can drill into any figure.

Sub-ledger vs general ledger

• The general ledger holds your summarized financial position — it's the system of record your statements come from.
• The sub-ledger holds the granular detail behind specific accounts (here, crypto), and reconciles up to the GL.

So a crypto sub-ledger doesn't replace your accounting system — it makes it possible to account for crypto properly, with every GL line traceable back to the underlying transaction. Crypto sub-ledger vs portfolio tracker →

What a crypto sub-ledger does

• Ingestion — every exchange and wallet, into one place
• Classification — trades, transfers, income, fees, DeFi, NFTs
• Cost basis — multiple methods, with jurisdiction-correct treatment → Cost-basis methods →
• Journal entries — summarized, double-entry, posted to your ERP → ERP integrations →
• Reconciliation & audit trail — every figure traceable to source

CryptaCount is a crypto sub-ledger

That's exactly what CryptaCount is built to be: the crypto sub-ledger that turns on-chain and exchange activity into accounting-grade records and posts them to QuickBooks, Xero, NetSuite, or Sage — with the transaction-level detail retained behind every line.
