## Atomic Swap Mechanism

An Atomic Swap Mechanism is a smart contract-based technology that allows the exchange of two different cryptocurrencies without the need for a centralized intermediary. It utilizes Hashed Time-Locked Contracts to ensure that either both parties receive their assets or neither does, effectively eliminating counterparty risk.

If one party fails to fulfill their side of the trade within a specified timeframe, the funds are automatically returned to the original owner. This mechanism is fundamental to trustless trading in decentralized finance, providing a secure way to swap assets across different chains.

It represents a core application of protocol-level logic to facilitate peer-to-peer market efficiency.
