03 · The problem

Markets moved onchain.
Access stayed fragmented.

Crypto traders use one platform for spot, another for perps and a third for yield. Equity investors sit in brokerage accounts with their own hours and settlement. Every platform keeps its own balance, margin, interface and liquidity.

3.1

Capital fragmentation

Stablecoins on one DEX, spot on another chain, stocks at a broker, hedges on a derivatives venue. Capital in one place cannot support a position anywhere else, so everyone over-collateralizes.

3.2

Market fragmentation

Crypto, equities, ETFs, FX and commodities live behind different venues and infrastructure. Even tokenized, their liquidity and UX stay isolated.

3.3

Inconsistent execution

Onchain trading asks you to choose: a simple but limited AMM, or a professional order book with unclear custody and settlement.

3.4

Opaque risk

Centralized venues hide leverage and liabilities. Many DEXs are transparent at the contract level yet unreadable for users. Health, thresholds, oracle state and reserves should be visible in the interface.

3.5

RWA-specific complexity

Market closures, corporate actions, regional eligibility, issuer restrictions, delayed reference prices, dividends and session gaps. Rivora treats these as core requirements, not afterthoughts.

UNIFY

Rivora unifies these markets: one non-custodial account, one risk engine, professional execution, and risk rules you can read.

05 · Positioning

Not another
perp DEX.

Robinhood Chain already has perpetual protocols. Rivora's defensible position is a chain-native cross-asset liquidity and portfolio-margin layer: the bridge between crypto-native liquidity and tokenized financial assets.

Hyperliquid showed onchain trading can feel professional. Aster showed demand for broad access. Rivora extends the model toward a unified market for crypto and tokenized finance on Robinhood Chain.
Unified access
Multiple asset classes through one interface and one account.
Self-custody
Assets stay under smart-contract control, never an opaque balance sheet.
Transparent risk
Margin, funding, liquidations, reserves and exposure can be inspected by anyone.
Programmability
Wallets, bots, vaults and agents build on the same liquidity and risk primitives.
Five product layers

06 · Market architecture

Five risk tiers.
Different rules for each.

Every group gets its own collateral factors, leverage ceiling, position limits, oracle requirements and liquidation rules. Long-tail markets never share the core insurance pool.

07 · End-to-end user flow

Feels like a pro exchange.
Settles like a chain.

01STEP

Connect wallet

Any Robinhood Chain wallet. Nothing leaves your keys.

02STEP

Smart account

Optional ERC-4337 account: gas sponsorship, batching, session keys with expiry, notional caps and no withdrawal rights.

03STEP

Deposit USDG

One approved settlement asset at launch. The interface shows available margin, equity, liquidation distance and max order size.

04STEP

Pick a market

Spot or perpetual, tiered by risk. Session-aware markets show their state before you size up.

05STEP

Margin mode

Isolated first. Cross and portfolio margin arrive as separate, proven upgrades.

06STEP

Set the order

Market, limit, stop, take-profit. Reduce-only, post-only, GTC or IOC.

07
GATE

Pre-trade risk check

The risk engine simulates the order. Rejected? Reduce size or add collateral, then retry.

08STEP

Sign

A typed EIP-712 order: account, market, side, price, size, time-in-force, nonce, expiry.

09STEP

Match & settle

Relayers find execution; contracts verify signature, nonce, balances and limits before updating your account onchain.

10STEP

Manage

Monitor PnL, funding and health. Modify, close, realize PnL, reuse collateral or withdraw.

Then reuse the collateral anywhere in the account.

08 · Protocol architecture

Hybrid signed orders.
Custody stays onchain.

Matching runs on high-performance relayers; custody, margin, positions, settlement, liquidations and withdrawals are enforced by contracts. More feasible for a first EVM deployment than promising a fully onchain high-frequency order book before the infrastructure exists.

System map
Web · mobile · API · agentsWallet / smart accountSigned-order gatewayMatcher + permissionless relayersOnchain settlement contractsMargin & position engineCollateral vaultFunding & fee engineLiquidation & insuranceOracle adapters & data streamsIndexers & analytics
A relayer can never
  • change an order's price or size
  • settle an expired or cancelled order
  • bypass a reduce-only condition
  • withdraw collateral
  • create a position that fails the onchain risk check
Contracts are the source of truth for
  • collateral ownership
  • active positions
  • average entry price
  • realized & unrealized PnL
  • funding payments
  • trading fees
  • margin requirements
  • liquidation state
  • withdrawable balance

If an indexer fails, users can still verify state and withdraw through the contracts or a minimal recovery interface.

10 · Margin model

Read the equations.
Then move the sliders.

Rivora starts with isolated margin. Cross-margin and portfolio margin ship as separate upgrades, only after risk performance is proven. The formulas below run in the terminal and in the relayer.

Healthy. Equity ÷ maintenance margin.

Equity = Adjusted collateral + Σ uPnL − fees − accrued funding

Initial margin = Σ (notional × IM rate)

Maintenance = Σ (notional × MM rate × risk multiplier)

Health = Equity ÷ Maintenance margin

Long-tail tokenIsolated or ineligibleLiquidity and manipulation

One dollar of volatile collateral never buys one dollar of borrowing power. Correlation benefits in portfolio margin are capped because correlations break under stress.

11 · Liquidation flow

Orderly deleveraging.
Never a cliff.

Rivora prioritizes partial liquidation and orderly deleveraging over immediate full account closure. The risk engine recalculates health continuously; every step down the ladder is visible in the terminal before it happens.

  1. 1

    Active

    Health above warning threshold

    Account trades normally.

  2. 2

    Warning

    Health below 1.25×

    Interface warns; risk-increasing orders restricted.

  3. 3

    Maintenance breach

    Equity below maintenance margin

    Cancel open risk-increasing orders.

  4. 4

    Partial liquidation

    Attempt to restore health

    Reduce a slice of the position at mark price. Restored? Back to active.

  5. 5

    Auction / backstop

    Partial reduction insufficient

    Liquidation auction or backstop vault takes the remainder.

  6. 6

    Insurance

    Residual loss

    Market-specific insurance reserve absorbs the deficit.

  7. 7

    Last resort

    Reserve insufficient

    Documented auto-deleveraging rules apply — never silently.

PROTECTIONS
  • Mark price, never a single last trade
  • Minimum oracle confidence before any liquidation
  • Partial position reduction first
  • Liquidation auctions where practical
  • Market-specific insurance accounting
  • Capped liquidator incentives
  • Open-interest and concentration limits
  • Emergency pause bounded by governance rules
  • Auto-deleveraging only as a documented last resort
12 · Oracle & price integrity

A market is only as safe
as its price data.

Primary feed, secondary reference and venue data flow through an adapter that checks freshness and deviation. Pass: compute index and mark. Fail: protective state — reduce leverage, block new risk, or pause settlement. The protocol never silently continues liquidations on stale or contradictory data.

13 · RWA market handling

Stocks have hours.
The risk engine knows.

Tokenized assets need a dedicated state machine. The existence of a token on Robinhood Chain does not make it eligible: Rivora reviews token contracts, transfer restrictions, issuer terms, oracle licensing, jurisdiction and user eligibility before enabling any market.

Open

Underlying market open. Normal trading parameters, continuous pricing and funding.

state · open

After-hours

Scheduled close. Lower leverage, higher margins, smaller max order, wider protection bands, tighter OI caps.

state · after_hours

Protective

Halt or stale feed. Block new risk or pause the market; resume only after feed and risk validation.

state · protective

Corporate action

Adjustment review and public notice. Contract specification adjusted deterministically with an onchain record.

state · corporate_action

Corporate-action policy
  • Stock splits and reverse splits
  • Cash and stock dividends
  • Mergers and acquisitions
  • Spin-offs
  • Delistings
  • Ticker changes
  • Prolonged trading halts

Every adjustment gets a public notice period when possible, deterministic calculation rules, and an auditable onchain record.

Funding, session-aware

Funding keeps a perpetual near its index and is exchanged between longs and shorts — it is not protocol yield. It considers the premium, the index, time-weighted observations, bounded rates, market-specific intervals, open-interest imbalance and protective rules during oracle disruption. For RWA-linked markets the parameters differ between the underlying's open and closed sessions.

14 · 17 · Liquidity & vaults

Market makers, community vaults,
no endless emissions.

Professional market makers and community vaults feed the order book; cross-chain deposits feed collateral. Trading fees flow back to market-maker incentives, the insurance reserve, security and operations, and the treasury. Raw volume is a poor incentive metric — it invites wash trading.

Vault deposits are at risk. Never marketed as guaranteed yield.

01

Market-making vault

Quotes both sides of approved markets.

02

Basis vault

Captures spot–perpetual basis.

03

Delta-neutral vault

Offsets direction while pursuing fees or funding.

04

Index vault

Tracks a defined crypto or RWA basket.

05

Liquidation vault

Capital for discounted liquidations under strict limits.

Vault lifecycle: proposal → code, permissions and risk review → guarded deployment with deposit cap → public monitoring → limits scale only if performance and risk stay acceptable; otherwise freeze deposits and unwind.

16 · Fee model

Simple for retail.
Flexible for makers.

Illustrative launch ranges — product assumptions, not commitments. Final fees depend on liquidity, market-maker agreements, infrastructure cost, risk and regional requirements.

18 · Token design

Optional for the MVP.
Useful if it exists.

Rivora should prove product demand before a token becomes central. If introduced, it carries operational utility — never equity, ownership in Robinhood, guaranteed revenue or a guaranteed appreciation mechanism.

19 · 24 · Governance & metrics

Volume is not the score.
Health is.

Governance decentralizes progressively: early multisig powers, signers, timelocks and upgrade paths are public; emergency actions expire unless confirmed. Success is measured on liquidity quality and account health, never raw volume alone.

Liquidity quality

  • · Median bid-ask spread
  • · Depth within price bands
  • · Market-maker uptime
  • · Slippage by order size
  • · Oracle-to-execution deviation
  • · Order-fill rate

User health

  • · Weekly active traders
  • · Retained funded accounts
  • · Average deposit duration
  • · Repeat trading behaviour
  • · Liquidation rate by market
  • · Share of users using risk controls

Protocol health

  • · Open interest vs insurance reserves
  • · Revenue excluding incentives
  • · Bad debt
  • · Insurance-fund drawdowns
  • · Relayer concentration
  • · Oracle incidents · uptime · governance participation

RWA health

  • · Session-gap losses
  • · Stale-price events
  • · Corporate-action accuracy
  • · Market availability
  • · Regional eligibility incidents

Governance scope

  • Market listing and delisting
  • Collateral eligibility
  • Position and OI limits
  • Margin and liquidation parameters
  • Fee ranges
  • Treasury budgets
  • Liquidity programs
  • Upgrade authorization
  • Risk-council selection

Proposal → technical and economic review → public discussion → routine vote or risk-council recommendation → timelock → onchain execution → post-execution monitoring. Emergency actors may pause new risk, disable a compromised oracle or cap a market — never withdraw user assets.

26 · Brand system

Liquid, modern,
asset-neutral.

The name reads as a trading terminal today and a market network later, and deliberately avoids putting “Robin” or “Hood” in the brand so nobody mistakes it for an official product. Name, domains, handles, ticker and trademarks still need a professional availability review before launch.
