Live double-entry engine

Every transaction, balanced on write

Watch a marketplace sale split into debits and credits, settle across accounts, and prove out to zero — in real time, never in a batch.

Use cases

Built for modern business

Whether you're building AI agents, SaaS products, or web3 applications.

Agentic commerce

Pay-per-use AI tools and MCP servers. Track credits, usage, and billing in real time as autonomous agents consume your services.

Credit-based SaaS

Usage billing, prepaid credits, and subscriptions. Flexible accounting for any billing model with instant balance queries.

Web3 + tokens

Native support for 18 decimal places — track ETH in Wei, not just whole tokens. On-chain ingestion with an offline 360° view.

The difference

Built for real-time, not batch

The problem

Traditional accounting systems weren't built for real-time, high-volume micro-transactions.

Batch processing delays leave balances stale
No support for pending & encumbered funds
Retrofitting ERPs is expensive and fragile

The solution

Ledga is an immutable, double-entry ledger designed for modern credit flows.

Balances computed on write, never stale
Multi-layer: settled, pending, encumbrance
API-first, built for developers

Getting started

From zero to balanced in three steps

A ledger, a transaction, a balance — the whole lifecycle behind one API.

Step 01

Configure your books

Set up a ledger with your currency and precision, then define the chart of accounts for your business model.

POST /api/v1/transactions

{
  "reference": "TXN-2026-0001",
  "description": "Customer payment",
  "entries": [
    { "account": "1000", "debit": "100.00" },
    { "account": "4000", "credit": "100.00" }
  ]
}

Transaction codes

Define complex financial movements once, execute them with a single API call.

Multi-currency

Introducing: Strings

One customer. Every currency. One ledger discipline. Strings let an account live across as many single-currency ledgers as you operate in — without merging them.

Why strings

Most ledgers force you to pick: keep currencies clean and run a separate ledger per currency, or smash them all into one ledger and lose the integrity that makes a ledger useful in the first place.

Ledga Strings give you both.

A String ties together a single-currency ledger per currency you operate in — and any account you create in one is mirrored across all of them. A customer wallet, an FX-suspense account, or a revenue line lives everywhere at once, and each ledger stays self-consistent.

Each ledger stays balanced in its own currency.

Auditors and regulators see a clean single-currency book, not a Frankenstein.

FX is explicit, not implicit.

A currency conversion is a real cross-ledger transaction with a known rate — not a hidden re-tag.

One API call for the whole portfolio.

Ask for a customer's balance once and get every currency back, with a base-currency total at today's rate.
