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.

Functionality

Initialization

Customizable via initialization for the following parameters:

• feeToken: Token address for the fee token
• feeAmount: Amount required from fee token (remember to adjust for token decimals)
• feeDestination: Destination address to send the fees to

Note that feeAmount can be set to 0 to dynamically remove or impose a toll without having to modify the organization's permissions.
