[OP Stack Deployment] Questions about configuring the L2 chain for contributing to RPGF from sequencer revenues.

[westonnelson]

Hey, all. I was just wondering if the preferred communication for questions is now on GitHub officially or if Discord still too?

Have some more questions for an OP Stack chain - specifically regarding the RPGF contribution from the specific L2 - where and what frequency should sequencer revenues be sent?

Can this be set with an immutable contract using 0xSplits to automate the process?

Best POC to get all the specifics on? (Contract addresses, currency accepted, converting native chain currency, etc.)

Thx 🫡

Weston

I'm not sure if this information addresses your concerns or not.

Hey @westonnelson,

I prefer technical questions to be directed to this forum, but Discord is also available to ask technical + general optimism questions. I personally prefer GitHub because:

• Its easier for me to track open questions, I often lose messages on Discord because I need to context switch often.
• Its easier to provide additional context and logs on GitHub
• Its nice to be able to use this as an additional resource for folks who have the same question and can self service their developer support by already answered questions or signal they're having the same open questions.

I still think Discord is a valuable additional channel for synchronous IM.

In regard to your question, @opfocus is on the right track here. The sequencer fees go into that vault, but we don't have the process around it documented. I'll work on finding that info and relaying it.

Awesome - thanks for the thorough response @sbvegan!

The more time I've spent researching getting this NFT rollup deployed, I think the vision for the L2 NFT chain built on the OP Stack is something that can and should still be done, and has a ton of potential, but that it might have to just come in time as all the details get ironed out such as this example.

For now, the NFTEarth application can serve most and new use cases simply being deployed on Base and OP Mainnet - I just think for high frequency transactions with our new MVP for the NFT product, the rollup and OP Stack does make the most sense.

Lmk if you have any more thoughts or if there is someone I should perhaps get in touch with.

Cheers! Weston

In regard to the SequencerFeeVault, this is where all the sequencer revenue goes and the smart contract has a simple withdrawal function that sends the ether to recipient address. Anyone can call this withdrawal function, as long as the amount is greater than the minimum withdrawal amount. The withdrawal can also be withdrawn to L1 or L2.

Here's the SequencerFeeVault and FeeVault implementations.

My primary thoughts on the NFT rollup idea are around the rollups economics and long term sustainability. I don't have all the numbers handy for OP Mainnet, but might be available on our dune dashboards. The operating cost is definitely a consideration that should be made.

I'm going to be working on some documentation soon for production chain operators and the considerations you should make before, during, and after deploying an op stack fork. So keep an eye out for that.

If you already have an application running on OP Mainnet, you can reach out to the optimism team with this form.

Legend! Thanks so much for the information @sbvegan

Yeah, so the use case I've been building out the architecture for in particular has to to with TONS of transactions - which is why I see the rolllup as necessity. It's about bringing tickets onchain using QR codes and other forms of NFTs but essentially going after big event... like NBA teams, to build the platform to host all the infra for their fan tickets and then would be able to expand into showing all the awesome new insights they could glean from the data they acquire about their fans, etc.

Will take a look at the form thx for sharing since we are live already. Maybe it's something that could be worked on sequentially...ie get it on OP Mainnet or Base and then transition to the rollup once clearly needed.

Also thanks for the SequencerFeeVault that is exactly the type of details was looking for.

Cheers. Weston

@westonnelson appreciated seeing you on Demo Day today! Since you're already live, have you had a chance to present yet? Especially we'd like a technical dive where you talk about your comparison of app vs rollup.

[westonnelson]

Hi @OPMattie, I would love to!

What would be the best way to proceed?

And re your question do you mean how I'm viewing this solution that working on designing and keep asking... "OK can we do this on OP Mainnet, or Base...or do we need an OP Stack chain to get the performance and specialized requirements for our app?"

Let me know the details, would love to come on and do some live demo cross-chain bridging in the app between Base and OP Mainnet and make it fun like see how fast can go from one chain to another or something!

Thank you. Weston

[OPMattie]

Awesome! This page has all the info, including how to sign up:

https://community.optimism.io/docs/contribute/demo-day/#

Let me know when you've added it and I'll let Jesse know to look for it.

Cross-chain bridging sounds great.
