A EIP55 compatible address encoding library

Package Exports

  • eip55
  • eip55/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (eip55) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

An EIP55 compatible address encoding library.

Example

let eip55 = require('eip55')

eip55.encode('0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359')
// => 0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359

eip55.verify('0xAcA128edBD274F2aBa534d67DD55Ebf67767B9A5')
// => true

eip55.verify('0xaca128edbd274f2aba534d67dd55ebf67767b9a5')
// => false

// The second argument of verify allows for single case addresses
// In this case it will only verify the leading 0x and length
// therefore the above example returns true instead of false

// lower case
eip55.verify('0xaca128edbd274f2aba534d67dd55ebf67767b9a5', true)
// => true

// upper case
eip55.verify('0xACA128EDBD274F2ABA534D67DD55EBF67767B9A5', true)
// => true

// EIP-1191 chainId support has been added
// pass the optional chainId to get the casing for that network

// Encode for RSK Mainnet (chainId 30) (notice the difference from above)
eip55.encode('0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359', 30)
// => 0xFb6916095cA1Df60bb79ce92cE3EA74c37c5d359

eip55.verify('0xFb6916095cA1Df60bb79ce92cE3EA74c37c5d359')
// => false (we need to pass the chainId)

// Note: the second argument is allowOneCase (default: false)
eip55.verify('0xFb6916095cA1Df60bb79ce92cE3EA74c37c5d359', false, 30)
// => true
