Offline Nano Wallet

Package Exports

  • @nano/wallet
  • @nano/wallet/nano.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 (@nano/wallet) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

LOCAL API

nano.generate()
nano.import( nano.generate() )
nano.accounts()
nano.add_account()
nano.sign(block, process.env.privateKey)
nano.convert('421.70', 'NANO', 'RAW') // 421700000000000000000000000000000
nano.encrypt('any_string', process.env.PASSWORD) // AES-256
nano.decrypt('any_string', process.env.PASSWORD) // UTF-8
nano.export(process.env.PASSWORD)

REQUIRES RPC

await nano.process(signedBlock)
await nano.balances()
await nano.receive()
await nano.send({ to: '@fosse', amount: 0.1 })
await nano.rpc({ action: "block_count" })

LOCALSTORAGE:

Build non-custodial Nano applications by persisting Wallets client-side. Using AES-256 ecryption. The longer process.env.PASSWORD, the more secure. 

nano.offline({ 
    filename: 'aes_encrypted_string.txt', 
    password: process.env.PASSWORD 
})

console.log( nano.accounts() )

await nano.receive()

await nano.send({ 
    to: [ 'nano_1faucet7b6xjyha7m13objpn5ubkquzd6ska8kwopzf1ecbfmn35d1zey3ys' ], 
    amount: nano.convert(0.001, 'NANO', 'RAW') // 'all'
})

IMPORT/EXPORT

A JSON string is encrypted with AES-256 using a user defined secret.

nano.offline({ 
    filename: 'aes_encrypted_string.txt', 
    password: process.env.PASSWORD 
})

console.log( nano.export() )
