01What Surety is

Surety does not run a matching engine and does not hold your funds. It is a front end and a thin server tier that route your intent to venues that already exist on Robinhood Chain, an EVM chain with id 4663.

The two paths share almost nothing except your wallet session and the chain underneath. That split explains most of what follows.

02Connect your wallet

Connecting is what proves an address is yours. It is not a payment and it does not move funds. Surety supports MetaMask, Phantom and Temple, and will provision an embedded wallet for anyone arriving without one.

1. Press Connect wallet

   Pick your wallet or sign in to have one created for you. You sign a plain message to prove ownership. No transaction, no gas, no approval of any token.

2. Switch to Robinhood Chain

   Robinhood Chain is the only network Surety supports. If your wallet sits on another chain you get an explicit switch prompt rather than a silent failure.

3. Fund the account

   Spot trading needs only the asset you are swapping and a little ETH for gas. Leverage needs a USDG deposit, which is what creates your account on the order book venue.

03Your first trade

Spot and leverage ask different things of your wallet. Spot is the shorter path.

Spot, in two signatures at most

If you are selling an ERC-20 you approve it once to Permit2, then Permit2 approves the router. Native ETH skips both. After that the swap is a single transaction. Your funds never sit with us.

Leverage, one authorisation then click to trade

The order book venue separates the wallet that owns an account from the key that signs its orders. That separation is what lets you trade without a wallet popup on every click. The one-time setup looks like this.

1. Deposit USDG

   Your first deposit into the venue contract is what mints your account index. Until it lands there is nothing to trade against.

2. A trading key is generated

   A key pair is created for your account. The private half is encrypted immediately. Your browser only ever sees the public key and its index.

3. Your wallet authorises that key

   You sign a gasless message binding the new key to your account. This is the moment you decide to let Surety place orders for you.

4. Trade without popups

   From here every order, cancel, close and take-profit or stop-loss is signed with that key. Your wallet is needed again only for deposits, withdrawals and transfers.

04Issuer, contract, entitlement

Every venue prints the price. Almost none prints the three things that decide what you actually hold. Surety prints all three next to every market it lists.

05Dividends and corporate actions

A share is a bundle of rights. A tokenized share usually delivers one of them: price. What happens to the rest depends entirely on the issuer, and that answer is almost never on the screen you trade from.

Holding a tokenized equity does not normally put your address on the issuer's shareholder register. A custodian or nominee holds legal title, and the terms of the wrapper decide whether a dividend is passed through, reinvested into the token's value, or not distributed at all.

We do not standardise that. We disclose it. For every equity and ETF market we list, the entitlement line states the issuer's actual treatment and links to the document that says so, so you can argue with the issuer rather than with us.

06Perpetuals

Perps run on a zero-knowledge order-book venue. Orders are cryptographically signed and submitted off chain, then settled in batches on Robinhood Chain. Collateral is USDG.

Between your click and a resting order there are three hops, and each exists for a reason.

browser          places intent, never holds a trading key
   ↓
surety api       auth boundary, one route per action
   ↓
signer           holds the encrypted key, signs the order
   ↓
order book       matches and settles on Robinhood Chain

The browser never learns a venue hostname for anything that requires authentication. Market orders re-read the live mark price immediately before signing and apply a slippage guard, so a stale quote on your screen cannot turn into a wildly mispriced fill.

07Spot

There is no hosted routing service anywhere in the spot path. Quotes are contract reads over RPC and fills go through the Universal Router. Slower to quote than a hosted router, and nobody sits between you and the pool.

Because a quote is a contract read and not a cached price, it is re-fetched immediately before execution and your slippage bound is computed against fresh state.

08Fees and treasury

Spot fee revenue goes to one treasury address. That address is published before the first trade, not after, so the flow is auditable on the block explorer from day one rather than asserted in a post.

09Keys and custody

This is the part most interfaces leave out, so here it is plainly.

Always yours

Your wallet's private key. It never leaves your wallet and we never see it. Deposits, withdrawals and transfers are signed by you and only by you.

Held for you

The trading key that signs your order-book orders. It is generated server side, encrypted at rest, and used only to place, cancel and close orders on the account you authorised it for. It cannot move funds to a third party. It is what buys you click-to-trade instead of a wallet popup per order.

What that means

If our signer were compromised, an attacker could trade your position, which can lose you money. They could not withdraw your collateral to their own address. If you are not comfortable with that trade-off, use spot, where every action is signed by your wallet and nothing is held for you.

10What can go wrong

• Leverage liquidates. A perpetual position can be closed at a loss without warning.
• A tokenized equity is only as good as its issuer. If the issuer fails, the token can trade away from the asset it references.
• Markets close. Equities have hours and corporate actions; a token that trades all day can gap when the underlying reopens.
• Look-alike contracts exist. Always check the address on the market page against the one in your wallet.
• We depend on venues we do not control. If they degrade, so do we, and we will say so rather than hide it.

Nothing here is financial advice. Trading involves risk, including the total loss of what you put in.
