Buy FIO Tokens

If a wallet wants to implement it’s own registration of FIO Domains and Addresses, e.g. to accommodate shopping cart or registrations on a private domain, they will be able to purchase enough FIO Tokens to purchase specific number of FIO Addresses or FIO Domains. Using this method, as opposed to purchasing a specific amount of FIO Tokens is preferred as the Registration site will adjust the amount of tokens to be sufficient for the fees, in case there is a fee change between a quote and processing of crypto payment.

Upon payment, the Registration site will transfer FIO Tokens to publicKey and notify webhook

Same as https://developers.fioprotocol.io/pages/api/fio-reg-api/#post-/buy-address

Processing

• Validate

  • Parameters as in https://developers.fioprotocol.io/pages/api/fio-reg-api/#post-/buy-address

  • Check if “Allow FIO Token Purchases” in wallet profile is not checked

    • Return success: false and error: “Not allowed for this referralCode.”

  • Ignore

    • domainRegistrations and addressRegistrations are not validated against wallet profile, meaning this call will work even if domain sale or address sale is disabled.

• Compute Order Amounts

  • FIO Tokens Order Amount is computed based on sum of:

    • domainRegistrations * get_fee for register_fio_domain

    • domainRegistrations * get_fee for set_fio_domain_public

    • addressRegistrations * get_fee for register_fio_address

  • USDC Order Amount is computed by converting FIO Tokens Order Amount to USDC and reducing it by Public Key’s Balance

• If USDC Order Amount => 0.25 USDC

  • Record order

    • Create Coinbase Commerce Order and record details

    • Record FIO Tokens Order Amount and USDC Order Amount

    • Record domainRegistrations and addressRegistrations

  • Return Response

• If USDC Order Amount < 0.25 USDC

  • See Payment Received Processing → If Status = Success

Payment Received Processing

Process same as other transactions except:

• Payment Received is reflected in USDC and is added to Public Key’s Balance

• Re-compute FIO Tokens Required Amount (see above)

• Re-compute USDC Required Amount

• Determine transaction status

  • If USDC Required Amount <= Public Key’s Balance

    • Public Key’s Balance is reduced by USDC Required Amount

    • Status is Success

  • If USDC Required Amount > Public Key’s Balance AND Public Key’s Balance > (USDC Required Amount * 0.9) AND payment was received within 60 minutes of request

    • Public Key’s Balance is reduced to 0

    • Status is Success

  • ELSE

    • Status is PriceChange

• If Status = Success

  • Transfer FIO Tokens Required Amount to public key

  • Fire Webhook

    • status: Success

    • amount: FIO Tokens Required Amount

• If Status = PriceChange

  • Fire Webhook

    • status: PriceChange

    • amount: 0

    • usdc_delta: USDC Required Amount - Public Key’s Balance
