Pirate Chain uses the 'b' prefix for P2SH addresses, but the light wallet library is configured to use 't3' (from Zcash), so it's easiest to just derive a different prefix for each destination. 

This could be simplified by configuring the light wallet library to use the correct 'b' prefix, but this didn't work when first attempted.
