Reddit is experimenting with community points using ERC20 tokens on Rinkeby
- Moons and Bricks ERC20 tokens are deployed on Rinkeby public testnet
- ERC20 tokens are upgradeable using OpenZeppelin Upgrades
- ERC20 tokens likely use OpenZeppelin Contracts ERC20 implementation (as they have increaseAllowance and decreaseAllowance functions).
- Meta transactions use Gas Station Network (GSNv1)
