Gringotts Bank App

Project Description

Wizards & witches can deposit their magical Ether currency into Gringotts bank for safe keeping. As a reward, Gringotts bank account hodlers will receive 1000 Galleons for making and hodling a deposit. Note that in the near future, before we launch our banking program to the main wizarding network on Ethereum, account hodlers must hodl a deposit for a minimum of 1 year without making any withdrawals to receive the Galleons reward. This will help Gringotts in its effort to create an ETH/GAL liquidity pool to further reward our account hodlers.

Here's how our system works:

Workflow

1. User connects MetaMask wallet
2. User deposits x ETH in their account
3. User's balance is updated once transaction is mined
4. User is rewarded Galleon tokens for using the protocol
