cryptoaddress-validator

CryptoCurrency address validator.

Description

After researching a lot online about validating crypto-currencies addresses without making API calls in daemons running in background, i found usefull scripts that did this action in client-side and attempted to port them to NodeJS javascript.

Sources

Didn't find any licences that would exclude publishing of the code, if the anyone feels that this package violates a licence, please feel free to contact me.

• The original source was from this thread at bitcoindtalk.

• the second source which the same code appears was found here. at stackoverflow.com

• my question which motivated me is here.

Dependencies

None , BigInt.js is the only depedency which is already inside the package, and its the minified version its used which makes only 17KB instead of 49KB.
