wallet module (wrapper) #25

As a developer, I would like to have a different module in neow3j that will act as a NEO wallet convenience layer. This module should be called wallet, that people can import using maven.

Tasks / Requirements:

  • Create a wallet java module
  • Provide a file-based database layer, to persist information (like a DAO)
  • Provide methods to get all past activity related to the wallet (e.g., performed transactions related to NEO, GAS, and other NEP-5 assets, when addresses were added, etc.)

The wallet module is intended to connect to one (or more) NEO nodes to perform JSON-RPC calls and get block information relevant for the addresses in the wallet. This information consists for example of UTXOs or transaction outputs for GAS claiming.
The wallet module, therefore, requires a file-based database (to be defined) in order to keep the wallets past activities (history).
It relies only on JSON-RPC nodes of version 2.10.2 and higher. It does not depend on other APIs, like the one of a neoscan server.

Features will be specified on different issues and might be referenced.

As of neo-cli version 2.10.2, there are new JSON-RPC methods that allow the retrieval of claimable GAS and unspent transaction outputs for any address. This removes the need for scanning the blockchain and persisting such information locally in a database. Neow3j will make use of the new RPC methods to retrieve such information. The issue description has been modified accordingly.

- Change Wallet and Account creation to a more congurent Builder pattern.
- Store private and public key directly on the account instead of credentials (provides better overview of the account when used e.g. for asset transfers).
- Add Balances to account.
- Provide a response interceptor for mocking RPC node responses.
