Functions and Usages

The DealsRepo is a public library that defines the deal object and its series of operation methods for adding, deleting, changing, and checking.

Deal Object

The deal object defines all the input parameters required to change the share bookkeeping, as well as a hash time lock in 32byte, using for by both parties when trade off-chain or pay equity consideration across the chain.

The basic transaction logic and common process of hash time lock is:

1. The seller sets the hash function value as the share combination lock, which locks the underlying share, and simultaneously sets the delivery deadline, beyond which the equity is automatically reversed and the delivery arrangement is revoked;

2. The buyer sets the same hash function value as the consideration combination lock off-chain or across the chain, locks the share transfer consideration (cryptocurrency, central bank digital currency or other programmable digital currency), and at the same time, sets the payment deadline, after which the payment will be reversed and the payment arrangement will be revoked;

3. The seller calls the unlocking API of the consideration combination lock, inputs the source data for generative hash function value, unlocks the combination lock, and withdraws the consideration for the share transfer;

4. The buyer utilizes the source data obtained during the unlocking process of the consideration combination lock to unlock the lock, and triggers the automatic registration change process in order to acquire the underlying share.

There are several key settings to be aware of for hash time lock arrangements:

1. Sellers should not hold the authority to revoke a delivery arrangement while the share combination lock is in effect;

2. The buyer should not hold the authority to revoke the payment arrangement while the payment combination lock is in effect;

3. the delivery deadline should be later than the payment deadline to allow sufficient action time for the buyer to withdraw the equity; and

4. It is recommended to set the counterparties of the share transfer and the consideration payment in the hash lock contract as a specific buyer and a specific payee, so as to avoid a third party from deciphering or intercepting the lock and obtaining the locked-in equity.
