Time-Lock Expiry Risk

Time-Lock Expiry Risk is the danger that a transaction in a time-locked contract will fail to execute before the defined deadline, causing the funds to be returned to the sender. This can happen due to network latency, gas price spikes, or technical issues with the user's transaction submission.

In the context of atomic swaps, an expired time-lock can lead to a failed trade where one party has already revealed their secret on another chain, potentially leaving them exposed. Managing this risk requires careful planning of expiration windows to account for the slowest chain involved in the transaction.

Users must ensure their transactions are prioritized by the network to avoid missing the deadline. It is a significant operational risk in decentralized finance that requires precise timing and monitoring.
