What is Hound
Wallet terminal for Robinhood Chain. Token and NFT leaderboards, wallet tracking, and trading in one screen.
Most trading tools point you at a chart and let you guess. Hound points you at the people.
It reads every trade on Robinhood Chain, works out who made money and who lost it, and ranks them. Not by what their open positions are worth on paper, but by what they actually closed. You pick a wallet off that board and the rest of the screen follows it.

Quickstart
Three things to do in the first five minutes
The Terminal
One screen, and how a click moves through it
How it works
The methods behind the numbers, and what they miss
The Engine
The service that reads the chain, over HTTP
What is live today
Two things work end to end. They are the two documented here in detail.
| Module | What it does | Where |
|---|---|---|
| Terminal | The live market screen. Tokens, NFT collections, and the wallets moving them, streaming a snapshot a second | /terminal |
| Autopsy | Paste any address. Realized PnL against watched inventory, position by position | /autopsy |
Behind both sits the engine, which holds the only connection to the chain and keeps the whole market in memory. It answers over HTTP too, if you would rather read the data than look at it.
What is not live yet
These three are named on the terminal and they are not real. Every panel that shows one is either empty or carrying sample data, and it says so on screen.
| Module | Will do | State |
|---|---|---|
| Pack | Rank the chain's most consistent traders over long windows | Queued first |
| Trail | Follow a winning wallet and ride its positions | Queued second |
| Nose | Read a contract for its danger signs before you buy | Queued third |
Trading is also unwired. The Buy and Sell controls exist, they are visibly disabled, and no route is connected behind them.
Why say this at all
A tool that ranks wallets by honesty has to start by being honest about itself. Everything above is either working or it is labelled. If you find a panel claiming something it cannot back, that is a bug and we want to hear about it.
What makes the numbers different
Two decisions do most of the work, and both are unusual enough to be worth knowing before you trust a single figure on the screen.
Profit means closed. A wallet's realized PnL only ever moves against inventory the engine watched being bought. Sell a token it never saw you acquire and that counts as activity, not profit. Most leaderboards in this category rank on unrealized PnL instead, which puts a wallet up 400% on a position it still holds at the top of the list. That wallet has won nothing yet. It is the next exit liquidity.
The engine does not keep a list of venues. It used to. That version caught 39.8% of the chain's swap transactions and looked like it was working. It now reads the value moving through each address in each transaction, so a swap at a pad that deployed this morning looks the same to it as a swap on Uniswap V3. That is 97.4% of position moving swap transactions, and the number that matters more is that it keeps finding trades at contracts no known signature explains.
Both are covered properly in How it works.
The chain
Robinhood Chain is an Arbitrum L2 that went to mainnet on 1 July 2026. Blocks land about every 100ms, there is no public mempool, and almost no trading tooling supports it yet. That last part is the reason this project exists.
The chain in one page covers what you need to know to read anything else here.
