Borrow the stock,
not the dollar.
Every lending market on Robinhood Chain takes a Stock Token as collateral and lends USDG. None of them lend the token itself, so nobody could short. Vadium lends the token: fixed term, fixed rate, and the lender keeps the price exposure.
Testnet desk. Prices come from the contract's own feed reader.
Three ways in, one contract
The same pool funds all three. A lender is the supply that a short and a loop both draw on, and the rate is fixed at the moment the loan opens.
Lend
Put a Stock Token in for 7, 30 or 90 days at the rate you ask. You keep the exposure to the stock and get paid in USDG for as long as it is borrowed.
principal back in the token, interest in USDG
Short
Post USDG and take the token, then sell it wherever the pool is. Buy it back before the term ends and keep the difference, or let someone close you if the price runs too far.
collateral 55 percent of value
Loop
Deposit a token, borrow USDG against it, swap into the token and deposit again, up to three rounds in one transaction. Exposure multiplies, the loan stays in USDG.
liquidation at 65 percent, everyone can close
How a loan runs
Terms are short on purpose. A stock feed stops when the session closes, so the desk never lets a loan sit through a weekend without a buffer.
- 01A lender opens a note. The token leaves the wallet, a maturity and a rate are written down. Nothing can change them afterwards.
- 02A borrower fills it. USDG goes in, the token comes out, at the feed price. A pool may sit two percent away from the feed, so the desk always values at the feed.
- 03Interest accrues by the second on the borrowed part only. Unfilled supply earns nothing and never pays a fake rate.
- 04The borrower repays the token plus the interest, and takes the collateral back. Repaying early costs less, because interest is per second.
- 05Or anyone closes the loan once the collateral falls under 65 percent of the debt, or the term plus one day of grace has passed. The closer brings the token and takes the collateral plus five percent.
- 06The lender redeems after maturity and gets the token back plus the interest in USDG. Principal is never priced in dollars, so a lender cannot lose the shares to a price move.
Doing it by hand, or here
Shorting a token you do not hold is not possible with a plain collateral market, and a variable rate cannot price a fixed term.
| What you need | By hand today | Vadium |
|---|---|---|
| Short a Stock Token | Not possible, nothing lends the token | Borrow it against USDG |
| Know the cost up front | Rates float every block | Rate fixed when the note opens |
| Earn on a holding | Sell it, or lend USDG instead | Lend the token, keep the exposure |
| Leverage a position | Loop by hand, several transactions | Three rounds in one call |
| Exit a bad loan | Whoever runs the market decides | Anyone can close it, no keeper |
What protects the money
Written into the contract, not into a policy page.
Feed, never the pool
Collateral and debt are valued at the Chainlink price. A pool that drifts does not move a liquidation.
Stale feed blocks new loans
If the feed has not been updated inside the maximum age, opening a loan reverts instead of pricing a stale number.
Principal is never in dollars
A lender gets the same token amount back. Interest is the only dollar figure in the contract.
No owner over user funds
The owner sets pairs, limits and the treasury. Moving a user position needs the borrower or a liquidation.
Terms shorter than a session gap
Grace is one day, and a note stops filling when it is inside the grace, so no loan is opened against a note about to expire.
Anyone can liquidate
No keeper key, no off chain bot needed. The five percent bonus is the whole incentive.
Questions
- Do I lose my shares if I lend them?
- You lose them for the term. They can be sold short by the borrower, and if a short goes bad the liquidator takes the USDG collateral, not your note. At maturity you get the same token amount back, plus interest in USDG.
- What happens on a dividend?
- Stock Tokens grow shares per token through the multiplier, and the feed folds it into the price. A short therefore pays the dividend through the price. A lender keeps it, because the principal is returned in tokens.
- Can the owner take the pool?
- No. The owner can add markets, set limits within hard bounds and send the accumulated fee to the treasury. A loan leaves only when the borrower repays or a liquidation closes it.
- What if the feed stops?
- Stock feeds stop between sessions. New loans revert while the feed is stale, existing loans wait, and liquidations use the last good price with the 65 percent threshold as the buffer.
- Is this audited?
- Not yet. The contracts are unaudited, the desk runs on testnet, and the numbers you see are a live testnet market, not a projection.
- Who can use it?
- Anyone with a wallet on the chain. Stock Tokens themselves are not offered to US persons and are restricted in Canada, the United Kingdom and Switzerland.
