XRPL-AccountLib npm version

XRPL Account helper: generation, derivation and signing.

Getting started

npm install --save xrpl-accountlib

The XRPL_Account object

Both the generate and the derive methods will return an XRPL_Account object, containing all information to sign:

{
  accountType: '...',
  address: 'rXXXXXXXXX...',
  secret:
   { familySeed: 'rYYYYYYYYY...',
     mnemonic: 'word word word...',
     passphrase: 'Hello World! ...',
     path: 'm/44'/144'/X'/Y/Z' },
  keypair:
   { algorithm: 'xxxxxxxx',
     publicKey: 'AABBCC001122...',
     privateKey: 'CCDDEE332211...' } }

All XRPL_Account objects allow calling the signAs method to set the signAs user for MultiSign transactions (when a MultiSign user also uses a RegularKey);

derive
  .familySeed('snYHBZDJ51PPSuzWYVhEh1kb9zvEU')
  .signAs('rPEPPER7kfTD9w2To4CQk6UCfuHM9c6GDY')

Methods

Generate account lib.generate

All generate methods return an XRPL_Account object.

Samples: https://github.com/WietseWind/xrpl-accountlib/blob/master/samples/generate.js

Family Seed lib.generate.familySeed(options{})

Options:

  • algorithm
    Default: 'secp256k1', alternatively: 'ed25519'

Secret Numbers lib.generate.secretNumbers()

See:

Mnemonic lib.generate.mnemonic(options{})

Options:

  • passphrase
    Default: (none), alternatively: 'my secret passsword'
  • strength
    Default: 256 (24 words), alternatively: 128 (12 words)
  • accountPath
    Default: 0, alternatively: X in the derivation path: m/44'/144'/X'/Y/Z
  • changePath
    Default: 0, alternatively: Y in the derivation path: m/44'/144'/X'/Y/Z
  • addressIndex
    Default: 0, alternatively: Z in the derivation path: m/44'/144'/X'/Y/Z
  • wordlist
    Default: 'english', alternatively one of:
    • chinese_simplified
    • chinese_traditional
    • french
    • italian
    • japanese
    • korean
    • spanish
    • english

Derive account lib.derive

All derive methods return an XRPL_Account object.

Samples: https://github.com/WietseWind/xrpl-accountlib/blob/master/samples/derive.js

Family Seed lib.derive.familySeed(familyseed'')

The familyseed argument is required, and should contain a string, like: sXXXXXXXXX...

Secret Numbers lib.derive.familySeed(secretNumbers''|[])

The secretNumbers argument is required, and should contain a string, like: 012345 123456 ... or an array containing 8 elements of the type string containing 6 digits.

Mnemonic lib.derive.mnemonic(mnemonic'', options{})

The _ mnemonic_ argument is required, and should contain a string with a valid word list, like: state green stem tower...

Options:

  • passphrase
    Default: (none), alternatively: 'my secret passsword'

Passphrase lib.derive.passphrase(passphrase'')

Derive from a passphrase, like masterpassphrase

Private Key lib.derive.privatekey(hex'')

Derive from a 66 char HEX private key, like 001ACAAEDECE405B2A958212629E16F2EB46B153EEE94CDD350FDEFF52795525B7

Sign lib.sign(Transaction{}, XRPL_Account{}/[{}])

The first argument of the sign-method should be a Transaction object, the second argument can either contain one XRPL_Account object (returned by either the generate or derive methods) or an array with multiple XRPL_Account objects (multiSign).

When combining previously signed MultiSign transactions as HEX blob, the second argument can also be an array with { signedTransaction: '...' } objects (or an array of strings with the HEX blob).

Samples

https://github.com/WietseWind/xrpl-accountlib/blob/master/samples/sign.js

Signing with one account:

lib.sign(Tx, lib.derive.familySeed('shqNUmrgnkBmK9iCijrtid2Ua4uHd'))

MultiSign

lib.sign(Tx, [
  lib.derive.familySeed('sp5mkm12oJj3t8fFRiaMNrDbc73N2'),
  lib.derive.familySeed('snYHBZDJ51PPSuzWYVhEh1kb9zvEU')
])

If you want to sign a single transaction that will be part of a MultiSigned transaction (combined later on) it's mandatory to specify the signAs account (with the chained (signAs( .. ) method). The output (signed transaction blob, hex) signed by multiple accounts can then be combined later on:

Sign a MultiSign transaction to combine later

lib.sign(
  Tx,
  lib.derive.familySeed('sp5mkm12oJj3t8XXXXXXXXXXXXXXX')
  	 .signAs('r9yzFismdTTWzc6Ea3mJr9by26QaFrFHP7')
)

Combine multiple signed HEX MultiSign transactions

const Tx = lib.sign([
   { signedTransaction: '120000240000000B2E000001EF614000000002FAF0806840000000000003E873008114723F34B08C70F3EF8759B1A2CD4934D434A3C2518314628891E80B72684CF065A0AE8EC3482472C1C0DCF3E010732103AC651208BDA639C7AEC10873771A5B5F1A2008CAB3B2155871EE16A966D5860774473045022100CD9BC97047BF8EE0AF2D7631540FFF4C5FFE863AFAA9E2DE7AD98156F3323CF9022031D0454947833536028029FB9B61B224F4C2BFC1D1F670C49880AD004A76315C8114723F34B08C70F3EF8759B1A2CD4934D434A3C251E1F1' },
   { signedTransaction: '12000024000000042E000001EF614000000007F81ED96840000000000003E873008114F84E8A80D08854F3621F9214D58F04D41A07EE108314F40B468D5AC0DBA36E2941877AC2E9BBD48262A1F3E010732103CA9799516799A1139BED8958A9FDD0033389396422B888A7E56FB9991B0A179E74473045022100B22D6874CC4ECC92D32E657A1F863245A4DB1B425260052A9427616BE397D244022023CA82B76ADD26909549381C5CCB7BB09084936B294577299F5796A22F5AC39E8114F40B468D5AC0DBA36E2941877AC2E9BBD48262A1E1F1' }
])

You can also pass the signed HEX blob as an array with strings.
