InterestBearingToken is a token that incentivates users to hold it, as longest time users hold bigger are the rewards.
The highlights are:
- Users can hold/transfer/burn: All ERC20 standard +burn functions are kept, and user´s actual balance is used to calculate the rewards.
- Configurable APY: Admin can set APY as many times as is necessary.
- Vault Contract: This solution was crafted to not need the presence of admin all the time, its just necessary the vault has some balance to pay the rewards.
- Redeable Rewards: Users can check and withdraw their rewards any time, and automatically this addition to balance starts to get rewards too.
- Foundry: Foundry was used as framework to craft and build the smartcontracts.
- Unit tests: A good number of unit tests for different use-cases.
