The UnseenEye
Cowl /kaʊl/ noun — a hood that conceals the head and identity. Here, the hood you wear to trade unseen on Robinhood Chain.
The hood, in your browser.
The protocol stopped living in a terminal. app.cowlprotocol.com runs it whole. One wallet signature derives your shielded keys, the ZK proof builds itself on your machine, and your private book opens in the same tab. Shield and unshield are live on Robinhood Chain mainnet right now, and the full trading set lands on the same shielded core.

They copy you.
✳Your wallet is a public feed. Wallet-watchers see every entry the moment it lands. They mirror your buy, sit in front of you, and your own accumulation moves the price against you before the position is even built.
They front-run you.
⊹Visible orders get sandwiched. MEV bots read your pending trade and jump the queue. You eat a worse fill so a bot can pocket the spread on your own intent.
Half-measures leak.
◇A privacy feature bolted on is still a public trade. A relayer here, a shielded transfer there — the metadata still bleeds. Protecting your edge takes a real ZK shielded pool built for it from the start.
Going dark isn’t enough.
⌁Hiding from the crowd can’t mean hiding from the law. Your edge is worth nothing if you can’t prove you’re clean when it counts. Privacy only holds up when it comes with selective disclosure — view keys for the people you owe answers to.
Your whole hand
is showing.

Takes the tell off the table.
Shielded Portfolio
Your book, off the explorer. Hold tokens and tokenized stocks inside a ZK shielded pool. Balances, size, and cost basis never appear on the public ledger — no wallet-watcher can read your position.
The stackbehind the shield.
Robinhood Chain
The Arbitrum-based L2 Cowl settles on — fast, cheap, and where your tokenized stocks already live.
ZK Shielded Pool
Your balances and trades live inside a ZK proof. The public ledger sees a commitment, not your book.
Stealth Addresses
Every deposit lands on a fresh stealth address. Nothing on-chain links the funds back to you.
Gasless Relayer
Trade without holding gas or doxxing a funding wallet. The gasless relayer pays — you stay unseen.
View Keys
Hand an auditor a read-only view key. Selective disclosure on your terms, not the whole crowd's.
USDG
Settle in USDG. A dollar peg that holds its value the whole way through the shield.
What Cowlgives you.
Shielded portfolio
Balances, positions, and P&L live in a ZK shielded pool. The block explorer only sees a commitment. Never your book.
Private trading
Your size, timing, and entries stop broadcasting. Stop handing the crowd your hand before you play it.
MEV & front-run shield
A bot can't front-run an order it can't see. Nothing to sandwich, nothing to copy-trade off your back.
Stealth addresses
Every deposit lands on a fresh stealth address. Nothing on-chain ties the funds, or the trades, back to you.
Selective disclosure
Hand an auditor a view key when you choose to. Prove what you owe, to exactly who's owed it. Nobody else sees in.
Gasless relayer
No gas balance. No doxxed funding wallet. The gasless relayer settles it, and you never touch the chain in the clear.
