Case Study

How Optimism Works With Blocknative to Improve The OP Builder Experience

Blocknative worked with the Optimism Foundation to secure a public good grant to enable L2 decoding in Ethernow.xyz.

Ethernow.xyz now displays details on each transaction (such as from/to, gas info, method signature, and more) within each Optimism L1 batch Rollup as well as summary info on each batch (such as parent hash and total transaction count).

This is available for both pending and confirmed Optimism batches - across both calldata and blobs.

Electric home page from the @blocknative team. Awesome transparency into every block and can’t wait to see what else they start to layer in!

@VitalikButerin

The big hard fork that will help a lot with that is coming in three days.

Real-time @base batch decoding is now live. Developers can now provide a smoother L1<>L2 experience, enhance visibility into mempool events, and troubleshoot issues quickly. Example decoded Base batch here:
