Build a one-page explorer that shows what's happening on Tacit, across both chains.

Tacit runs on two chains. Assets are issued and moved in Taproot envelopes on Bitcoin, and the same confidential notes live in a pool on Ethereum (plus Base and Robinhood Chain), with SP1 proofs carrying state between them. tacitscan.io already decodes the Bitcoin envelopes. Nobody has built one page that shows the whole system: Bitcoin activity, the confidential pools, and the bridge between them.

Vibecode it. Any stack, any AI tool, any style.

What a great entry shows

Pick what you think matters most. Strong entries will cover some of:

• Bitcoin side: recent envelopes (etches, transfers, mints, burns), assets, and the Bitcoin-native AMM pool
• Ethereum / Base side: pool activity, deposits and withdrawals, relayed ops, cBTC / cUSD / wTAC
• The bridge: header relay height, the latest proven roots, and bridge burns and mints in flight
• The privacy boundary: what an observer can see (timing, counts, fees, public addresses) and what stays hidden (amounts, links between notes). Showing this honestly is a plus.
• Look up your own footprint: paste a tacit1 ID, a Bitcoin txid or an EVM address and see what's public about it

XNS bonus: show EVM addresses as XNS names (alice@xns) where one exists, or let people search by XNS name.

Requirements

Your submission must:

• be a live public URL that anyone can open, no wallet or sign-in needed to browse
• read real mainnet data (Tacit's public APIs, the indexer, RPC or block explorers). No mock data.
• link a public source repo
• never ask for seed phrases or private keys, and never move funds
• be posted publicly on X, tagging @tacitfi, Tacit's founder @z0r0zzz, and the bounty creator @davidpereIsHIM (plus @xns if you use the XNS bonus)
• be submitted before Sunday, November 15 at 11:59 PM PT

How to enter

1. Build and deploy your explorer.
2. Post it on X with a screenshot or short screen recording.
3. Claim on this bounty with a screenshot, and put your live URL, repo and X post in the description.

Winner

One winner gets the full pool. It's seeded with $10, and anyone can add funds. After the deadline, contributors review the entries and pick the winner.

We're judging on:

• Useful: would you actually keep it open?
• Correct: do the numbers match the chain?
• Clear: does it make Tacit's two chains easier to understand?
• Honest about privacy: what's public and what's hidden

Ugly-but-correct beats pretty-but-fake.
