@Chronos, The smart lending contract is short term, ie one week. For example, on 1st Sep. I submit a contract request to borrow some NBTs from protocol where I specify a NBT address and a NSR address of mine. I deposite 3000$ value NSR(on price of that day) and protocol will check if my NSR is sufficient (deny too small contract). Because the pledge ratio is voted at 50%, so I am automatically given 1500NBT by protocol.
When protocol and I sign the lending contract, I actually send 3000$ NSR to protocol but the transfer is intentional postponed by protocol to 7th Sep., and at the same time protocol send 1500NBT to my address.
I use this 1500NBT to provide liquidity by Bot, at 7 Sep, I have to send back 1500NBT to the protocol otherwise my NSR will transfered to protocol.
During 1st to 7th Sep, protocol may check the pledge NSR value and have the option to cancel the contract, and I can cancel contract at any time by sending back 1500NBT. Because I temporarily holding my 3000$ NSR, I can still vote and mint until they are actually transfered to protocol.
Shortly after my returning of 1500NBT on 7th Sep. my wallet automatically submit a new contract with same clauses, and system passes it again.
I can setup an automatically timing of NBT payment from my NBT address with extra NBT in case of Nubot bug/flatform default that lends to stuck of borrowed NBT on exchange, so I can’t lose my NSR accidentally.
For me, every thusday is the contract day when new contract signed and old contracts end. I can check the status mannually or automatically operated by wallet. If NSR price halved, the protocol will sign with me a new contract by sending 750NBT to me.
To sum up, the protocol always keep pledged NSR and in one week, the NSR price is relative stable. Nu system is immune to LPC hacked/stolen/run off and in this way, protocol can control the circulation of NBT because the pledge ratio can voted to 10% which lends to dramatically decrease of NBT supply, or voted to 10000% which can provide 100 times NBT value of NSR market cap. If pledge ratio is 10000%, even 300%. the free market’s organic demand for NBT will definitely decreases or the NSR price will go up. Nu system interacts with free market. We can NOT arbitrarily decides the pledge ratio such as 50% or 100% regardless the free market demends. In fact it is the free market demands drive shareholders to vote a proper ratio. If the market is sane, our pledge ratio is sane, if market is insane, our ratio is also insane such as 1000% ratio.
when pledge ratio is above 100% that means a LPC may run off with more valuable NBT and discard NSR. The risk is taken by both sides: free market may suffer NBT pegging failure and lose money and Nu will suffer reputation demage, so win win solution is NSR price rise since our business is so good just like apple inc.
