How Arbiter DEX Works

Unified marketplace for tokenized assets with fair pricing: every venue compared, one independent referee.

Arbiter DEX is live Beta

Swaps are real: you sign them from your own address and they settle on Robinhood Chain. Beta means more products are still on the way.

Swaps are live today

36 verified stock and fund tokens, ETH and USDG, routed through Uniswap v3 and judged against Chainlink.

Other products are marked

Baskets, lending, pools deposits, private settlement and the launchpad show a Preview or Soon label until they open.

Prices depend on venues

Liquidity comes from public pools. Outside US market hours stock pools are thinner and oracle updates pause, so rulings can widen.

Overview

Arbiter DEX is a decentralized exchange that acts as an arbiter for tokenized assets. When the same stock token trades in several pools, their prices drift apart, and a trader rarely knows which one is honest. Arbiter DEX reads every venue, compares them with an independent oracle, and tells you how fair the best executable price is before you sign.

It never holds your funds. Trades go from your own address to a public router contract and back to your address, in one transaction you approve in your own wallet. There is no account, no deposit and no identity check.

Today the live product is the swap on Robinhood Chain. Markets and Tokenized Pools show live venue data. Baskets, lending and private settlement are shown as previews and say so on every page.

Swap and Bridge

SwapSame network. Trade one asset for another on Robinhood Chain, for example USDG → NVDA.
BridgeAcross networks. Move value into or out of Robinhood Chain. Not open yet.

The Swap tab is live. The Bridge tab explains what is coming and stays disabled until routes are verified.

How a trade works

  1. 1Choose what to send and receivePick two verified assets and enter the amount you want to send.
  2. 2Every route is quotedDirect pools at every fee tier and two-hop routes through ETH or USDG are quoted on-chain by the Uniswap quoter, up to 36 routes per order.
  3. 3The ruling appearsThe best route is compared with the oracle's fair value and labelled Fair, Within tolerance or Unfair, with the exact gap shown.
  4. 4Approve and signTokens other than ETH need an approval for exactly this amount, never unlimited. Then one signature sends the swap.
  5. 5Settled on-chainThe trade lands in your wallet with a link to the public explorer. If the price moves past your slippage limit the swap reverts and only gas is spent.

How a ruling is made

A fair price needs a witness that does not profit from the trade. Arbiter DEX uses the Chainlink price feed for each asset on Robinhood Chain as that witness. The fair output is your amount times the oracle price of what you send, divided by the oracle price of what you receive.

FairThe best route gives up less than 0.5% against fair value.
Within toleranceThe best route gives up between 0.5% and 1.5%.
Unfair right nowEvery route gives up more than 1.5%. You can still trade, knowingly.
No referenceOne side has no oracle feed, so only venue prices are compared.

Stock feeds follow US market hours on weekdays. Outside them the oracle holds the last close while pools keep trading, so a gap can reflect news rather than a bad pool. The ruling shows the oracle price used so you can judge that yourself.

Tokenized Baskets

A basket is a set of verified stock tokens at stated weights. Baskets are valued live from the oracle prices of their legs. Buying a whole basket in one order is not open yet; until it is, each leg links to the swap.

Index baskets Preview

Fixed weights published up front, such as a broad-market or chip-maker basket. The page shows each leg, its weight and its live oracle price.

Automated baskets Preview

Rule-based portfolios, such as equal weight or a treasury ladder, that will rebalance on a schedule you can read before you join. The rules are shown; the automation is not running yet.

Strategy baskets Preview

A list of stocks and weights with no basket token: you would hold each stock token yourself. Strategies follow written rules, never a named person's trades.

Issuers and verification Live

Dozens of tokens on Robinhood Chain copy the ticker of a famous stock. Arbiter DEX only lists a stock token when three things hold on-chain: the contract is a proxy to the issuer's token beacon, its symbol matches the ticker, and its name carries the issuer's suffix. Look-alikes are counted on each asset page and never routed.

Tokenized Pools Live

Tokenized Pools lists every public pool on Robinhood Chain that trades a verified asset, with liquidity and 24-hour volume read live. Adding liquidity from Arbiter DEX is not open yet.

Lend and Borrow Soon

Borrowing USDG against tokenized assets, valued at the oracle price, is planned. The Lend page shows the proposed collateral list and limits; no position can be opened yet.

Fees

Arbiter DEX feeNone on swaps today. Nothing is added to the route.
Pool feeEach Uniswap pool charges its own fee tier (0.01% to 1%), shown in the route name and already inside the quote.
Network feeGas on Robinhood Chain, paid in ETH by your wallet.
SlippageYour limit (0.1%, 0.5% or 1%) sets the minimum you accept. It is a ceiling, not a charge.

Private settlement Soon

Moving an asset to a fresh address without an on-chain link to the sender is planned for larger transfers. It will be slower than a swap and every transfer will be screened. The Private tab describes it and stays disabled until it opens.

Tracking a trade

After you sign, the swap card shows each step: approval, swap and settlement. When it lands you get a link to the transaction on Blockscout. The Settlement Explorer shows recent swaps on the pools Arbiter DEX compares.

Safety

  • Your keys never leave your wallet. Connecting shares only your address.
  • Approvals are for the exact amount of one trade, never unlimited.
  • Swaps go through Uniswap's published SwapRouter02 on Robinhood Chain: 0xcaf681a66d020601342297493863e78c959e5cb2. Quotes come from QuoterV2: 0x33e885ed0ec9bf04ecfb19341582aadcb4c8a9e7.
  • Only verified issuer contracts are routed. Always check the address of anything you receive.
  • Stock tokens are issued by their issuer, who can pause or restrict them. That risk sits with the token, not with the route.

FAQ

Is the best price always the fair price?

No. The best route is simply the one that pays most right now. The ruling tells you how that compares with an independent reference, so a thin market cannot pass itself off as a good one.

Why is my ruling "Unfair" for a large order?

Pools move against size. Try a smaller amount; the gap usually narrows.

Does Arbiter DEX take custody or ask for identity?

No. There is no account and no deposit. Your wallet signs and sends every transaction.

Where is the $ARBITERDEX contract?

It is published at launch. Until then every copy button on the site says so instead of copying a placeholder.
