Handling price changes
Preserve FIO pricing and USDC pricing for cart
When payment is received compare total price of cart when saved to what it is at the time when payment notification is received
If price deviation is +/- 25% from saved price do not alter pricing and execute transaction
If price deviation is more than +/- 25% reprice send FIO to User’s account at new rate of exchange
Registering FCHs on private domain when not paid with FIO
If cart contains a FCH on a domain owned by the user check domain status (private/public)
If owner wallet is a Ledger Wallet registration of FCH on private domain is not allowed
Display error: “At this moment registration of FIO Cryptyo Handles on private domains is not supported. We are working hard to add this capability to the Ledger’s FIO App.”
If the FCH being registered is on a private domain (domain registered in the same transaction will be private):
Have the user sign a transaction registering that FCH using pay with FIO functionality (PIN code will be required immediately after they click Purchase)
Set the
max_fee
parameter to 125% of fee obtained from get_fee forregister_fio_address
Once payment is received (e.g. webhook notification from Stripe received):
If domain is being registered in the same purchase, register it first
If registration fails, automatically fail FCH registrations on that domain
Re-check current
register_fio_address
feeIf just obtained
register_fio_address
is more than the fee signed by user in the step above fail FCH registration
Send FIO Tokens to user in the amount of just obtained
register_fio_address
If transaction fails with
Insufficient funds to cover fee
:re-check current
register_fio_address
feeSend users the difference between new fee and number of tokens they received
Resubmit the transaction with higher fee
