Atomic Swap

Last Updated: January 11, 2026

Atomic Swap is a secure, peer-to-peer exchange between cryptocurrencies without intermediaries.

Atomic Swap is a technology enabling direct peer-to-peer cryptocurrency exchanges between different blockchains without intermediaries. It uses smart contracts to ensure both parties fulfill their obligations in the trade. This eliminates the need for centralized exchanges, reducing risks like hacks or fraud. The process relies on a cryptographic technique called Hashed Timelock Contracts (HTLCs). This ensures that either both parties complete the trade or no funds are exchanged. Atomic Swaps enhance security and efficiency, making cryptocurrency trading more decentralized and trustless.
