Robinhood Chain.

The same pool, on Robinhood Chain

Offchange runs on Robinhood Chain for coins launched on Pons. It works the way it does on Solana: hide a sell or a buy at your price, or take what rests at market, and nothing touches the chart. You pay and receive ETH.

Before you start

1. 1
   An EVM wallet: MetaMask, Rabby or any wallet that can add a network. Offchange asks it to switch to Robinhood Chain, and adds the chain if the wallet doesn't know it yet. Phantom's EVM side can't add new networks, so use another wallet here.
2. 2
   ETH on Robinhood Chain for the trade and its gas. Gas is a fraction of a cent.
3. 3
   The coin's address. Robinhood Chain coins start with 0x; paste one in the navbar or the pool and Offchange knows which chain it lives on.

Trade

1. 1
   Paste the coin. With no EVM wallet connected the button reads Connect an EVM wallet.
2. 2
   Limit: size it and set your price, then Hide sell order or Hide buy order. A sell asks your wallet twice the first time: once to let the escrow contract move exactly that many coins, once to hide the order.
3. 3
   Market: one transaction takes every resting order the size needs. Selling into bids asks for the same one-time approval first.
4. 4
   Cancel from Your orders on Robinhood Chain, under the order card, at any time.

What's different

A contract, not a program. Orders sit in an escrow contract that can't be upgraded: nobody can change its code after it was deployed. Its admin can pause new orders and fills and change the fee, up to 1%. Cancel always works, paused or not.

Your wallet sends the fill. The matching engine signs an approval for exactly the orders you take, for your wallet only, once, within two minutes. The contract checks that approval and every order's sealed price before anything moves.

Pons coins only. The pool checks on chain that a Pons factory launched the coin. The contract also refuses any coin that takes a cut of a transfer.

No $OFF here yet. $OFF lives on Solana, so Robinhood Chain has no holding rule and no Ghost mode for now. The fee is the same 0.5%, paid in ETH.

The contract

0x8A072c83CbEaabfe2d59D85e037D810bb67386e9 on Robinhood Chain (chain id 4663). It was tested against a copy of mainnet with a live Pons coin. It is newer than the Solana program and hasn't had a security scan yet; see Risks.
