Simple wallet address validator and normalizer for cryptocurrencies addresses in Ruby.

Inspired by ognus/wallet-address-validator.


Add this line to your application's Gemfile:

gem 'adequate_crypto_address'

Or install it yourself as:

gem install adequate_crypto_address

Main API

.valid? (address, currency [, type = :prod])
  • address - Wallet address to validate.
  • currency - Currency name string or symbol in any case, :bitcoin or 'BTC' or :btc or 'BitCoin'
  • type - Optional. You can enforce validation with specific type. Not all currencies support types.

Returns true if the address (string) is a valid wallet address for the crypto currency specified, see below for supported currencies.

Supported crypto currencies

  • Bitcoin/BTC, 'bitcoin' or 'BTC' types: :segwit_v0_keyhash :segwit_v0_scripthash :hash160 :p2sh
  • BitcoinCash/BCH, 'bitcoincash' or 'BCH' types: :p2sh :p2pkh :p2pkhtest :p2shtest
  • Dash, 'dash' or 'DASH' types: :prod :test
  • Zcash/ZEC, 'zcash' or 'ZEC' types: :prod :test
  • Ethereum/ETH, 'ethereum' or 'ETH'
  • Ripple/XRP, 'ripple' or 'XRP'
