This is Kordio Ledger, the record half of the platform. Kordio Control decides what your software may spend before it spends; the ledger keeps the books for what it did.

Trading & investments

One workspace for the financial record.

Reconcile movements, inspect balances, and trace the postings behind every number.

Kordio Ledger workspace for trading & investments, showing balanced postings.

The friction

Where trading platforms hit the ledger wall.

01
Balances race with fills.
A fill posts, a fee posts, a sweep posts, and for a few seconds three tables disagree about what the trader holds. Support tickets live in those seconds.
02
Multi-asset means multi-table.
One table for USD, one for USDT, one for BTC, each with its own rounding rules. Every new listing adds another place for the books to split.
03
Audit trails you assembled with joins.
When the regulator asks why a balance changed, the answer is a 40-line query across five tables that someone wrote at 2am.

Why Kordio

Built for the way you actually operate.

Balances that keep up with fills.: Post every fill as a balanced transaction and read an authoritative balance immediately. Pending and posted are tracked separately.
Every asset in one journal.: Fiat, stablecoins, and crypto in integer minor units, with per-currency balance checks at write time. A new listing lands in the same journal.
An audit trail without the joins.: Append-only postings with idempotency keys and replayable webhooks. The history of any balance is a single query.

Where to go next

Three questions, in the order people ask them.

Everything above is the ledger applied to trading & investments. These are the pages that answer whether it is right for you, and what it costs if it is.

What the ledger does: Balanced postings, reconciliation against what actually cleared, period close, and the reports finance asks for.
Build it, or buy it: When writing your own is the right call, the five signals it has run out, and the eight things that cost more than the schema.
What it costs: Priced on postings a month, not on seats. Free in test mode with no card, and every number published.

Every fill on the books, the moment it happens.
