Quickly and easily generate custom unspendable burn wallet addresses for virtually any bitcoin-cloned cryptocurrency

generic-unspendable

The generic-unspendable script generates a valid base58 encoded address string that meets the validation checks for most cryptocurrency networks but is generated in such a way that the private key can never be found. This is useful for generating a coin burn address where any coins sent to the address can never be recovered. Using this method also allows injecting a vanity keyword into the address so that the address visibly looks much less like a random address and more like the burn address it is meant to be.

USAGE:

Simply call the python script and pass in the cryptocurrency's address prefix and a vanity keyword that will appear directly after the prefix. For example, to generate a burn address for the Bitcoin network you can use the following:

$ ./unspendable.py 1 BurnAddress
Result: 1BurnAddressXXXXXXXXXXXXXXXXV7cPS6
Decimal Address Prefix: 0

The first argument of 1 is the address prefix for the Bitcoin network.
The 2nd argument of BurnAddress is the vanity keyword to insert.

NOTE: Only certain alphanumeric characters are valid for the address prefix and vanity keyword. The list of valid characters are: 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz

The actual address is 1BurnAddressXXXXXXXXXXXXXXXXV7cPS6 and as an added check, the decimal address prefix of 0 is also displayed to eliminate guessing. The decimal address prefix must match the 2nd bit in the PUBKEY_ADDRESS of the coin's source code or else the address will not be valid. Click here to view the PUBKEY_ADDRESS for Bitcoin's mainnet. If you are not able to generate a valid address for your network it is most likely because the decimal address prefix doesn't match. You may have to change the vanity keyword to something that starts with a different number or letter to find one that matches your network's decimal address prefix.
