A Hashed Time-Lock Contract (HTLC) is a set of transaction types that permits a designated party (the "sender/seller") to LOCK funds by disclosing the preimage (secret) of a hash. It also permits a second party (the "recipient/buyer") to CLAIM the funds, or after a timeout is reached enter a REFUND situation.

The purpose of this transaction is to LOCK funds of the sender and make them possible for retrieval by the recipient, if they know the shared secret.
