Hey everyone! 🦉

We just launched **SilentBid** on the Midnight Preprod Network. It’s a zero-knowledge sealed-bid marketplace where you can place hidden bids on assets. Your bid stays 100% private until settlement using ZK circuits!

**How to try it:**

1. Connect your Lace / 1AM wallet (Make sure you are on the Preprod network)
2. Get some testnet tNIGHT from the faucet
3. Try placing a private bid or creating a dummy auction!

🔗 **Demo:** [midnight-sealed-bid-marketplace.vercel.app](https://midnight-sealed-bid-marketplace.vercel.app)

💻 **Source Code:** [GitHub - efekrbas/midnight-sealed-bid-marketplace · GitHub](http://github.com/efekrbas/midnight-sealed-bid-marketplace)

We would love to hear your feedback or answer any questions you might have about our Compact implementation!
