## Atomic Transaction Security

Atomic transaction security relies on the fundamental property of blockchain transactions where a series of operations either succeed entirely or fail entirely. In the context of derivatives, this atomicity ensures that if a user swaps assets or opens a position, all related state changes occur as a single unit of work.

If any part of the operation fails, the entire transaction is reverted, preventing the protocol from entering a partially completed or inconsistent state. This is a powerful tool for preventing financial loss during volatile market conditions or when interacting with complex, multi-step smart contracts.

By leveraging the underlying consensus engine to guarantee atomicity, protocols can build secure trading mechanisms that eliminate the risk of partial execution. It is the bedrock upon which trustless financial exchange is built.

## Glossary

### [Smart Contract](https://term.greeks.live/area/smart-contract/)

Function ⎊ A smart contract is a self-executing agreement where the terms between parties are directly written into lines of code, stored and run on a blockchain.

### [Security Guarantees](https://term.greeks.live/area/security-guarantees/)

Collateral ⎊ Security guarantees within cryptocurrency derivatives frequently manifest as over-collateralization, demanding deposits exceeding the notional value of the contract to mitigate counterparty risk.
