# Transactions

> Overview of Transactions in Midaz — balances, overdraft, events, async processing, bulk recording, and operations that keep financial value moving safely.

Transactions are where financial value moves. This section covers balances, transaction processing, events, and operations.

## Content

***

Here, you'll find:

* [**Balances**](/en/midaz/balances): The value an account holds. Balances reflect every operation over time and support multiple balance keys to segment funds within one account.

* [**Balance Overdraft**](/en/midaz/balance-overdraft): Controlled negative balances. When a balance goes negative, Midaz caps its available amount at zero and records the deficit as a debit on a companion overdraft balance.

* [**Transactions**](/en/midaz/transactions): Complete financial events built on Midaz's double-entry accounting. Every transaction pairs debits and credits, and they must balance before Midaz commits it.

* [**Transaction amount**](/en/midaz/amount): How Midaz stores financial values as precise decimals. This keeps values accurate across all asset types, from fiat currency to high-precision crypto tokens.

* [**Event publisher**](/en/midaz/event-publisher): Real-time event publishing for transaction updates. When you enable it, every transaction emits an event to a dedicated RabbitMQ exchange. External applications consume it without a tight dependency.

* [**Receiving events from Midaz**](/en/midaz/receiving-midaz-events): Consume ledger events in two ways. Bind directly to Midaz's RabbitMQ exchanges, or subscribe through the Streaming Hub.

* [**Async transaction processing**](/en/midaz/async-transaction-processing): How Midaz decouples transaction writes with RabbitMQ for higher throughput and lower latency. It covers sync and async modes, built-in resilience, and balance synchronization.

* [**Bulk Recorder**](/en/midaz/bulk-recorder): Batch transaction processing that groups multiple writes into one bulk operation. It reduces database round trips and increases throughput for high-volume workloads.

* [**Operations**](/en/midaz/operations): The smallest unit of financial activity — a single ledger entry, either a debit or a credit on a specific account. Operations form the building blocks of every transaction.
