GM Optimism!
On behalf of the Walnut 1 team, I am excited to announce that we have reached Milestone 2 of the OP Scan project, which received an OP grant in Season 5 , cycle 19 .
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 open-source explorer for the OP Stack. It runs on a laptop, enabling anyone building OP Stack chains to connect and explore transactions locally. It’s production-ready and scalable for Rollup-as-a-Service providers to use for their chains. The code is well-crafted and structured, making it easy for anyone to customize.
Milestones Overview: where we are
Milestone 1 : Build the MVP :white_check_mark: (link to announcement 2 )
Milestone 2 : Expanded tx Detail Page :white_check_mark: ← this announcement
Milestone 3 : Expanded contract detail page with contract verification ← up next

What we delivered in Milestone 2
The second Milestone addressed primarily the transaction details page which has been augmented to display gas prices and fees, from/to addresses, ERC 20 token transfers, preliminary work on input data decoding as well as transaction status and confirmations.
Here’s an example transaction details page of a basic ERC 20 transfer:

Here is a quick selfie from Optimistic Gathering in Brussels last week. On the picture with Nikolas, the CTO from superseed.xyz, a rollup on the OP Stack. Nikolas was very interested in the explorer, and we discussed the key values that a great explorer needs to offer — especially performance and good UX.
What’s next
You can review all of the upcoming milestones and deliverables on CharmVerse 1 .
Notably, in the next milestone, we will focus on the contract page and contract verification.
We also plan to encourage more users to test the product and share their feedback.
