app3.apis.accounts

The app3.apis.accounts contains functions to generate APIS accounts and sign transactions and data.

Note

This package has NOT been audited and might potentially be unsafe. Take precautions to clear memory properly, store the private keys safely, and test transaction receiving and sending functionality properly before using in production!

To use this package standalone use:

var Accounts = require('app3-apis-accounts');

// Passing in the apis or app3 package is necessary to allow retrieving chainId, gasPrice and nonce automatically
// for accounts.signTransaction().
var accounts = new Accounts('ws://localhost:8546');

create

app3.apis.accounts.create([entropy]);

Generates an account object with private key and public key.

Parameters

1. entropy - String (optional): A random string to increase entropy. If given it should be at least 32 characters. If none is given a random string will be generated using randomhex.

Returns

Object - The account object with the following structure:

• address - string: The account address.
• privateKey - string: The accounts private key. This should never be shared or stored unencrypted in localstorage! Also make sure to null the memory after usage.
• signTransaction(tx [, callback]) - Function: The function to sign transactions. See app3.apis.accounts.signTransaction() for more.
• sign(data) - Function: The function to sign transactions. See app3.apis.accounts.sign() for more.
