Tollgate forwarder

A simple Aragon App forwarder that requires a user to deposit fees before executing an action.

Useful for when an organization wants to make actions public, but impose a customizable cost to prevent spam.

Note that this forwarder does not accept native ETH as a fee.

🚨 Not yet audited, use at your own risk

The Tollgate contract has not yet been professionally audited. It is simple, but use with this asterisk in mind.
