Thank you very much for your feedback. Sorry for not getting earlier back to you.
We will try to incorporate these issues into the tutorial video.

re: eth deposit - the paymaster pays with its deposit to the paymaster. It can withdraw this value anytime (using withdrawRelayHubDepositTo()) the deposited amount can be anything you're comfortable with.

• Forwarder as constructor param: a contract is required to know its forwarder in order to work. its either a constructor parameter, or a setter functions (which also implies the contract is ownable - which is also acceptable).
• boilerplate: very interesting idea. Once we see some use-cases, we can add scripts to automate them.
• paymaster management: indeed, such a tool would be nice, though for the simplest use case (fund the paymaster) you can simply point your metamask at it, and transfer funds.

@drortirosh No worries! Jumping into this thread since we already opened the conversation.

• re: Forwarder, I'm going to try using a proxy contract in between an existing contract which would take _msgSender() and see if I can get some traction like that.
• I'm actually going to try that for a project where users submit EIP-712 permits for relay, in this case to a very simple contract which uses msg.sender so likely will have to prepend a proxy contract that would call the original one.
• My uses case is allowing Poster's users to pay for other people's gas costs, which means that I would need to deploy GSN on their behalf that they need to manage. I'll toy with this concept and see if I produce any tooling we can reuse.

Let's hope we can get OpenGSN to a point it's as easy as this to call a Relayer, and a few clicks to deploy and fund the Paymaster.
