Parameters

secret_hash (str) – secret sha-256 hash.
recipient_public (str) – Bytom recipient public key.
sender_public (str) – Bytom sender public key.
sequence (int) – Bytom sequence number(expiration block), defaults to Bytom config sequence.
use_script (bool) – Initialize HTLC by using script, default to False.

Returns

HTLC – Bytom Hash Time Lock Contract (HTLC) instance.
