How Fractio works

Overview

Fractio is a curator layer for isolated Morpho Blue markets on Robinhood Chain. Users post tokenized equities (and ETH) as collateral and borrow USDG without selling their upside. Markets are priced by Chainlink. While Fractio is small, the curator takes no performance fee.

Live protocol / curator addresses are published in the CA chip (Telegram-operated). Until a CA is set, treat app writes as unavailable.

Vision & mission

Ownership should meet liquidity. One share can have a thousand holders — and every holder should be able to borrow against it without selling. Fractio exists so tokenized equity on Robinhood Chain can work as productive collateral, not idle brokerage inventory.

Architecture

• IsolatedMarket (per ticker) — Morpho Blue market params curated by Fractio
• Collateral — tokenized NVDA / SPY / AAPL / ETH adapters
• Loan asset — USDG
• Oracle — Chainlink price feeds
• Curator / IRM / LLTV — risk parameters published with the live CA set

Mechanism — Deposit collateral

User selects a market, approves the collateral token, and supplies into the isolated Morpho market (or wrapper used by Fractio).

• Fields: marketId / ticker, amount
• Caller: user wallet on chainId 4663
• Reverts if: wrong network, insufficient balance/allowance, market paused or unset CA

Mechanism — Borrow USDG

Against posted collateral, user borrows USDG up to the market LLTV. Health factor is derived from Chainlink prices in real time.

• Functions: borrow(amount) after collateral is supplied
• Reverts if: borrow would breach LLTV, oracle stale, liquidity insufficient

Mechanism — Repay & withdraw

User repays USDG (approve + repay), restoring health, then withdraws collateral in full when debt is cleared (or partially when health allows).

• Reverts if: repay amount exceeds debt accounting, withdraw would undercollateralize remaining debt

Mechanism — Isolated markets

Each collateral asset is its own market. A shock in one ticker never shares risk with another.

Mechanism — Chainlink pricing

Collateral valuation uses Chainlink feeds (or chain-equivalent). Stale or deviant oracles should block unsafe borrows. Displayed LTVs in the app refresh from onchain reads when CA + ABI are bound.

Fees

While Fractio is small, the curator takes no performance fee. Market interest accrues to lenders per Morpho Blue mechanics. Any future fee switch will be documented here and reflected onchain.

Trust — Custody model

• You: control supply, borrow, repay, withdraw from your position
• Anyone (liquidator): may liquidate unhealthy positions per Morpho rules
• Protocol / curator: sets market params; does not custody user funds outside encoded market contracts — admin messaging targets none for discretionary withdrawal

Trust — Cryptography & safety

• User actions signed by wallet (EOA — Robinhood / Phantom)
• Consensus security inherits from Robinhood Chain
• Reentrancy-safe market interactions; reject fee-on-transfer collateral unless explicitly supported

Trust — Risks

• Liquidation if collateral price falls vs debt
• Smart-contract risk (Morpho Blue + adapters + curator config)
• Oracle staleness or manipulation surface
• Tokenized equity / regulatory uncertainty
• Interest accrual and liquidity shortfalls
• Nothing here is financial, legal, or investment advice

Protocol — Reference

Protocol — live CA

Canonical protocol / curator address is live-operated: message the Telegram bot with 0x + 40 hex. Open tabs update the chip via SSE (+1s poll fallback).
