It's a way where any person can use their Digital Assets/Digital Currency as Collateral/borrow against and be issued loans in the form of Stablecoins
If it's bitcoin, you may utilize
OP_CLTV for the collateral.
By the way, I didn't reply for your co-founding request, I just mentioned this to expand
my reply to your other thread because it might be off-topic there.
For example, based from BIP65:
github.com/bitcoin/bips/blob/master/bip-0065.mediawiki#escrowYou can set Lender's pubKeys as the current owner before that expiry (
he can spend it, the borrow can't), because he's technically the owner of the collateral until the borrower repaid his debts.
Then, set the Borrower's pubKey to be the sole owner of the output after a certain period (
e.g.: after the agreed full repayment date with a few days allowance)
So, the example script should look like this (
you can get creative on your own version):
IF
<Lender's pubkey> CHECKSIGVERIFY
ELSE
<full repayment date> CHECKLOCKTIMEVERIFY DROP
<Borrower's pubkey>
ENDIF
CHECKSIG
With it, the lender can spend it if the borrower defaulted, which he must do before the expiry. (
if he spent it prematurely, the borrower is entitled not to repay the loan)
Else, the borrower should repay the loan and the lender can either spend it to send to the borrower's wallet or wait for the expiry so the lender can spend it himself.
It works better with "
Atomic Swap" to make the trade fully decentralized.
