Farcaster Marketplace but with auctions using collectibles.

Sell random electronics and other stuff.

Coordinate shipping in DMs.

Shipping address / doxxing might be the most tricky.

We built this as a mini app for base batches hackathon. 

Payment held in escrow until item arrives. 
 
Shipping address is sent to the seller, E2E encrypted, at the end of auction but if there's any dispute, we use XMTP for communications so you can just pay from a burner address and not link your identity to mailing address.
