Stocks in, dollars out

Tetsu runs along a rail bridge through a night city in the rain, an airship overhead

Storyあらすじ

In a city that never closes, stocks live on Robinhood Chain and dollars always run short. Tetsu, a courier with steel hands, keeps a credit shop where a stock token is the only ID you need. Lock a stock and she lends you USDG. Bring USDG and her three drones farm it out to the borrowers who pay.

Borrow

Lock a stock token as collateral. Borrow USDG against it.

Repay any time and the stock comes back. No credit check. No selling.

Lend

Got USDG? Drop it in a farm.

Borrowers pay interest. Your farm shares grow with it.

Farm

KIRA-02

Borrowers are busy in NVDA. Moving USDG there.

Each farm has a drone agent. It places the farm's USDG where borrowers pay, and anyone can wake it.

Every loan is a Morpho Blue market.Every farm is a Morpho Vault V2.Tetsu Corp adds the price adapters, the agents and this cockpit.

赤い線を越えるな

The red line

TETSU

Every stock has a line. Stay under it and the loan is yours as long as you like. Cross it and anyone can repay your loan and take your collateral at a bonus.

  • Interest runs every second at the market's borrow rate. Busy markets cost more, quiet ones less.
  • No fees to open, add, repay or close. Gas on Robinhood Chain is a few cents at most.
  • The bonus a liquidator takes is up to 15% of what they repay. The rest of your collateral stays yours.

    取扱説明書

    Pilot's manual: wWhat can go wrong

    1. W-01

      Liquidation

      If a loan crosses its stock's line, anyone can repay part of it and take collateral at a bonus of up to 15%. Watch your health, add collateral or repay early.

    2. W-02

      Weekend gaps

      Prices come from Chainlink feeds that update 24 hours a day, five days a week. A stock can open far from Friday's price. If a feed is silent for five days, its market stops new borrowing, collateral withdrawals and liquidations until it updates. Repaying and adding collateral still work.

    3. W-03

      Lending losses

      Farms lend to borrowers. If a stock falls faster than liquidators act, a market can take a loss, and the farm lending there shares it.

    4. W-04

      Withdrawals

      Part of a farm is lent out. Withdrawals come from free cash, and the agent can free more from quiet markets, but not money a borrower holds until it is repaid or liquidated.

    5. W-05

      New code

      Loans and farms run on Morpho Blue and Morpho Vault V2, deployed by Morpho. Tetsu Corp's own contracts, the price adapters and the agents, are new and have had no outside audit. Raising a farm's caps, or changing its adapters, allocators or fees, waits three days.

    6. W-06

      Stock tokens

      Robinhood stock tokens are issued by Robinhood under its own terms. Check what you hold, and what applies where you live, before you borrow against it.

    テツに聞け

    Ask Tetsu

    Do I need an account?

    TETSU

    No. Connect a wallet on Robinhood Chain. No sign-up, no credit check: the stock you deposit is the collateral.

    Where does the farm yield come from?

    TETSU

    Only from borrowers' interest. My drones place USDG where borrowers pay. Each farm keeps 10% of the interest as its fee to Tetsu Corp, the rest goes to depositors.

    Can an agent run off with my money?

    TETSU

    No. An agent is an allocator of a Morpho Vault V2. The vault lets it move USDG only between markets the farm capped in advance, and raising a cap waits three days. Your farm shares stay in your wallet.

    How much can I borrow?

    TETSU

    Up to 85% of the stock's line, so a fresh loan always starts with room. A 62.5% line lets you borrow about 53% of the stock's value.

    Which wallets work?

    TETSU

    Any wallet that can add a network: MetaMask, Rabby, Coinbase Wallet, Trust Wallet and others. On a phone, open tetsucorp.si inside your wallet app, or tap Connect and pick it.

    Where do I get stock tokens?

    TETSU

    Robinhood stock tokens live on Robinhood Chain. If your wallet already holds them, they show up the moment you connect.
