Hub

The Hub is LitDEX's social layer. Everything is on-chain — friend lists, messages, listings, names, transfers. There is no off-chain database; the dApp reads directly from the LiteForge registry, posts, marketplace, and messenger contracts.

What's inside

• Private Chat — DMs between two .lit names, end-to-end stored as content hashes on chain
• Global Feed — public posts visible to everyone, with likes, comments, and tip rewards
• .lit Market — list and buy .lit names with bids, accepts, rejects
• .lit Domain Registration — register a new name with duration-based pricing
• Profile — your bio, your owned names, transfer history

Getting in

You need a .lit name to enter the Hub. Without one, the Hub gates with a "Claim your .lit name" prompt and routes you to the Buy page.

If you've never registered, follow Getting Started → Register a .lit Name first.

How the Hub stays in sync

• Friends list: read from LitDeXMessenger.getFriends(address).
• DMs: each message is an on-chain event with (from, to, contentHash, msgType). The dApp resolves contentHash via the Hub indexer to retrieve the message body. Friend-only by default.
• Global feed: Posts.postCount() + getPost(id) for every post. Likes and comments are events.
• Market listings: Marketplace.getActiveListings() returns all open listings + bids.

Every action — sending a message, posting, listing — is a transaction. There are no draft saves or off-chain queues. If you sign, it lands on chain.

Daily caps

The Hub's messaging rewards run on a daily counter. See Messenger → Daily Caps for the breakdown.

Why on-chain everything?

• Censorship resistance — a .lit name is yours forever, the registry can't take it back.
• Verifiable history — every message and listing is reproducible from chain state.
• Composability — third parties can build on top of the same data without API keys.
