christiangenco / bitcoin_address_validator.rb
Last active January 2, 2016 19:09 — forked from sashazykov/bitcoin_address_validator.rb
Simple Rails bitcoin address validation. Doesn't calculate the checksum or anything fancy - just checks that the address starts with a 1 or 3, consists only of alphanumeric characters, and is 27-34 characters long (from https://en.bitcoin.it/wiki/Address).
class User < ActiveRecord::Base
validates :bitcoin_address, format: { with: /\A(1|3)[a-zA-Z1-9]{26,33}\z/,
message: "invalid bitcoin address" }
end
