[Loans] - Escrow gateway

[dorucioclea]

User story:

I need to be able to view the offered terms of the loan (interest rate) and either approve or reject them

Acceptance criteria

• The importer while viewing a specific transaction should see the corresponding purchase contract and the details.
• The importer should be able to see what the final terms are offered by those financing the loan. For example, loan stakers are willing to offer the 5% APY for the duration of the loan
• The importer should be able to see what the final terms are offered by the insurance for the loan. For example, the protocol calculates 1.5% one-time premium
• If the importer approves the terms, the loan amount should be payed into the escrow to be held until the terms of when payment to exporter are met i.e. proof of shipment has been uploaded or goods have been accepted
• If the importer rejects the terms, the loan should return to the protocol for one more round of competitive bidding from loan stakers

Development:

• Escrow gateway contract
  • Used to track the assets held in escrow for a certain loan as collateral
  • Used to allow exporters to redeem the assets when the loan acceptance conditions have been met
