The Account class models Antelope accounts and is the primary entity used to interact with the blockchain. A contract can be deployed on an account and used to send transactions and read table data.

Accounts are created using the createAccount method of the Chain object.

Properties

name: string

Account name

chain: Chain

Reference to the Chain instance this account belongs to

contract: Contract

The contract installed on the account if it exists

Constructor

constructor(chain: Chain, name: string): Account

parameters

  1. chain - chain: Instance of the Chain class
  2. name - string: Name of the new antelope account

Note: The recommended method of creating a new account is to call Chain.createAccount()

Methods

updateAuth(permission: string, parent: string, threshold: number, keys, accounts, waits = [])

Updates the permission for an account.

parameters

  1. permission - string: permission name
  2. parent - string: parent permission name
  3. threshold - number: number of weights required
  4. keys - keys: list of public keys and weights
  5. accounts: list of accounts and weights
  6. waits: list of time weights and waits

Example

Add the permission testauth as a child of the active permission. The testauth permission will have a threshold of 2 and two keys each with a weight of 1. The permission [email protected] will have a weight of 2.

    await account.updateAuth(
      'testauth',
      'active',
      2,
      [
        {
          key: 'EOS7Gk5QTRcKsK5grAuZkLyPTSw5AcQpCz2VDWGi5DPBvfZAG7H9b',
          weight: 1,
        },
        {
          key: 'EOS8cFt6PzBL79kp9vPwWoX8V6cjwgShbfUsyisiZ1M8QaFgZtep6',
          weight: 1,
        },
      ],
      [
        {
          permission: {
            actor: 'acc11.test',
            permission: 'eosio.code',
          },
          weight: 2,
        },
      ]
    );
