• New Explorer for the OP Stack: Milestone 3 submission and request for feedback by romanm - No Role
  Posted on: Sept. 25, 2024, 9:40 a.m.
  Content: GM Optimism! On behalf of the Walnut team, I am excited to announce that we have reached Milestone 3 of the OP Scan 3 project, which received an OP grant in Season 5 , cycle 19 1 . In this post, we detail what has been delivered and what’s next. We encourage you to try out the tool (instructions below) and share your feedback. TL;DR: What is OP Scan? OP Scan is a new, lightweight, local, and fully open-source explorer for the OP Stack. It runs on a laptop, enabling anyone building OP Stack chains to connect and explore transactions locally. Once production-ready, Rollup-as-a-Service providers can also use it for their chains. The code is well-crafted and structured, making it easy for anyone to customize. Milestones Overview Milestone 1 : Build the MVP :white_check_mark: (link to announcement 1 ) Milestone 2 : Expanded tx Detail Page :white_check_mark: (link to announcement) Milestone 3 : Expanded contract detail page with contract verification ← this announcement Milestone 4 : UX improvements, Documentation, Superchain ← up next What we delivered in Milestone 3 The third Milestone was all about building the address page to correctly display info about EOAs and Contracts deployed on the OP Stack. We implemented token holdings, transactions overview, token transfers (ERC 20 ), NFT transfers (ERC 721 / 1155 ) and events emitted by contracts. We also built a verify contract page powered by Sourcify to provide contract verification alongside a verified contract page displaying the contract source code and ABI. You can test a live version of the explorer configured for optimism sepolia here 3 . (there’s no indexer being run in parallel though so it won’t update in realtime). List of transactions for an EOA. 1540 × 974 84 . 3 KB List of ERC 20 transfers. 1540 × 974 75 . 3 KB List of ERC 721 / 1155 transfers. 1540 × 974 63 . 4 KB Events emitted by a contract. 1522 × 1000 88 . 1 KB Contract verification step 11540 × 974 54 . 1 KB Contract verification step 21540 × 974 65 . 9 KB Contract verified page. 1525 × 2680 339 KB What’s next You can review all of the upcoming milestones and deliverables on CharmVerse. Notably, in the next milestone, we will focus polishing the UX and adding fancy features like keyboard shortcuts for best UX :nail_care:. We also plan to encourage more users to test the product and share their feedback. CTA: Looking for Rollup Builders! If you know rollup teams building on the OP Stack, chances are they will be interested in this explorer. Here is why they could want it: Open source (= free) Etherscan-like UX Lightweight & fast, runs locally on a laptop Please make an intro!

• Op stack Cumulative Dashboard? by romanm - No Role
  Posted on: June 17, 2024, 9:46 a.m.
  Content: There are many dashboards that monitor rollups, so I am not sure there is a need for another one. It might be a better approach to extend some of the existing dashboards with more metrics, as you requested, instead of building yet another dashboard. rollup.wtf is another one to check out, which has not yet been linked here. It does contain data like TPS or gas / sec. There is a Feedback at the bottom you can use to request more info.

• [READY TO VOTE] Decentralized rollup-as-a-service by romanm - No Role
  Posted on: June 3, 2024, 5:54 a.m.
  Content: Hello @ 0 xMilton I just noticed that in one of your milestones for the decentralized rollup-as-a-service platform, you have this item: “Add Block explorer feature to rollup service” We are building a lightweight open source block explorer as part of our mission grant, link here 4 — we actually got the grant in the same cycle as you :slight_smile: I believe our explorer would be an excellent option for your RaaS! Feel free to ping me on Telegram (@rmazur) or email (roman @ walnut dot dev) to discuss integration.
