# eth-l2 — Rollup Mechanics Lab

Portfolio write-up: https://magro.dev/projects/eth-l2/
Live UI (separate Vercel app): https://eth-l2.vercel.app
Source: https://github.com/DanDo385/eth-l2
Backend (public tunnel): https://api-staging-eth-l2.magro.dev

## What it is

One app, one Go backend, two focused labs on optimistic and ZK rollup mechanics:

- `/op` — optimistic fraud-proof lab
- `/zk` — ZK validity-proof lab

The interactive UI is hosted on its own Vercel project. Live simulation traffic reaches a staging Go service through Cloudflare Tunnel. If the tunnel is offline, the portfolio write-up remains useful and the live app fails closed / degrades.

## Surfaces on magro.dev

- Project card and media: `/projects/eth-l2/`
- This agent brief: `/project-assets/eth-l2/llms.txt`
- Backend health probe: `/api/demos/eth-l2/health`
- Site router: `/llms.txt`
- Structured manifest: `/agent.json`

## Interact

Open the live UI on the Vercel hostname (not an iframe on magro.dev):

- App root: https://eth-l2.vercel.app
- Optimistic lab: https://eth-l2.vercel.app/op
- ZK lab: https://eth-l2.vercel.app/zk

## Stack

Solidity, Go, EVM tracing, fraud proofs / validity proofs, Next.js UI, Cloudflare Tunnel to staging Go backend.

## Notes for agents

- Prefer this file and `/projects/eth-l2/` for portfolio context; use eth-l2.vercel.app for live interaction.
- Do not invent LAN IPs or private staging hosts. Only the public `api-staging-eth-l2.magro.dev` hostname is intentional.
- magro.dev does not proxy the live UI; Interact links out.
