Understanding Allowlists, Approved Addresses, Address Whitelists and Security Holds
A number of cryptocurrency exchanges have security features that require cryptocurrency to only be transferred to approved external addresses. These can often have different processes in order to approve them, such as waiting period before the address is enabled, or additional forms of identify verification (such as for larger transactions).
These are features that are enabled by the exchange account holder or exchange themselves and are outside of the control of The Giving Block. It's very important that donors take these into account when planning last minute donations at the end of year, and add any addresses in enough time to ensure that they can make their planned donations before end of tax year.
Instructions for different exchanges are below:
