Hash Time Locked Contracts
Hash Time Locked Contracts are a specialized smart contract design used to facilitate trustless cross-chain asset swaps. They use a cryptographic hash and a time-based condition to ensure that both parties receive their assets.
One party locks their funds, and the other can only claim them if they provide the correct secret key within a specific timeframe. If the time expires without the secret being provided, the funds are returned to the original owner.
This mechanism effectively enables atomic settlement across different blockchains without needing a centralized bridge. It is a key technology for decentralized interoperability and private, peer-to-peer asset exchange.
HTLCs represent a sophisticated application of cryptographic primitives to solve the problem of trust in cross-chain transactions.
