Overview

A representation of a blockchain Address that belongs to a Coinbase::Wallet. Addresses are used to send and receive Assets, and should be created using Wallet#create_address. Addresses require an Eth::Key to sign transaction data.

Constructor Details

#initialize(model, key) ⇒ WalletAddress

Returns a new Address object. Do not use this method directly. Instead, use Wallet#create_address, or use the Wallet’s default_address.

Parameters:

  • model (Coinbase::Client::Address) —

    The underlying Address object

  • key (Eth::Key) —

    The key backing the Address. Can be nil.
