Withdraw Crypto using FIO Crypto Handles & FIO Requests

FIO Crypto Handles (aka FIO Addresses) are human-readable wallet identifiers (such as [email protected] or [email protected]) which eliminate the need to see, or even know of, blockchain public addresses. Enabling withdrawals using FIO Crypto Handles give exchange users friendly interwallet operability, making withdrawals easy and near error-free, dramatically reducing support tickets.

Using a FIO Crypto Handle (FIO Send)

To enable withdrawals using a FIO Crypto Handle, an exchange would would first ask for the FIO Crypto Handle of the user receiving the funds. Next, the corresponding public address for that chain is looked-up using /get_pub_address and the transfer is executed by the Exchange on the native chain.

Using a FIO Request

If users of the exchange were assigned unique FIO Crypto Handles or if users provided the exchange, ahead of time, with a list of FIO Crypto Handles which the user owns, they could also send a FIO Request from their wallet to the exchange’s FIO Crypto Handle (either generic, e.g. [email protected], or unique, e.g. [email protected]).

The user would then login to the exchange and approve the FIO Request. Once approved, the exchange would execute the transfer on the native chain.
