has anyone ever managed to make an altcoin wallet that always makes addresses that start with a particular combination ?

for example :- for litecoin having all wallets produce addresses that look like LiteXXXXX

Mission Complete

OTP

Has anyone ever ditched the standard wallet encryption of bitcoin based coins in favor of implementing a OTP type of wallet access?


Single wallet == Single address

Ever been tried ? I know it's hard to enforce.

Use Cases

Vanity

If i had an exchange , i would love a modded wallet so that all users would get an address that is kind of "branded"

ie 1MtGoX or Bittrex (coins that start with a B)

OTP

I find that having a static-encrypted-salted password is great security thus far for bitcoin wallets, though i'd love it if the password changed over time much like Google auth.

Single Wallet

Just curiosity

Update

I have successfully managed to modify a test wallet for my Oracle project to produce only addresses with a specific prefix : XEA

Now researching adding OTP like google authentication to the wallet.

cool feature, actually is quite useful when scanning bunches of my addresses.

Update

Managed to get a wallet to limit addresses to a single one and return all change to that same address. It's incredibly convenient, even more so now that i realize i can use just ONE private key across ALL bitcoin based coins.

A set of well secured backups would ensure i never lose access to any coins, and the change address issue is instantly neutralized. Perfect for grandma's bitcoins!!
