ERC20Stakeable Smart Contract.

The goal is to create a ERC20 Stakeable library easy to implement for any token.

This Smart Contract is not Audited!

Created using OpenZeppelin ERC20 Smart Contract and ERC20Burnable extension.

Inspired by Patrick Collins' DeFi-minimal Staking.sol.

Features for users:

1. Deposit the ERC20 Token and gain a fixed APR calculated hourly.
2. Compound your rewards.
3. Claim your rewards.
4. Withdraw a part of deposit.
5. Withdraw all(your deposit + rewards).

Features for owner:

1. Set a fixed APR.
2. Set a minimum stake amount.
3. Set compounding frequency limit.

How to use?

Prerequisites:

Rinkeby deployment

• Python
• Brownie

python3 -m pip install --user pipx
python3 -m pipx ensurepath
# restart terminal
pipx install eth-brownie

• A free Infura Project Id key for Rinkeby Network

Installation
