Why lend or borrow on Borro

Borro is a loan desk for nine Robinhood stock tokens on Robinhood Chain. People come to it from four sides: with stock to lend, with dollars to lend, wanting dollars, or wanting to short. Here is what each side gets, what it costs, and how it compares with what else is on the chain. Every rate below is at today's rate, and today's rates move.

If you hold stock. A stock token in a wallet earns nothing. Lent on Borro, it goes into that stock's vault and you hold the vault's shares in your own wallet. Shorters pay rent while they borrow it, and you keep the stock's ups and downs, because what you get back is stock. Rent floats with demand, and right now it is close to zero: on October 15, about $2.40 of stock was on loan across all nine vaults. On top of rent sits the $BORRO Drip: 146,520 $BORRO a day, 60% to stock lenders and 40% to USDG lenders, by the dollar value each holds. At today's $BORRO price that is about $73 a day shared by stock lenders and $49 a day shared by USDG lenders.

Why that rate is not a forecast. The stock lenders who count for the Drip hold about $2,117 today, so a new $1,000 of stock would earn about 856% a year at today's rate. That number falls as deposits grow. With $100,000 more lent beside it, the same Drip pays about 26% a year; with $1 million, about 2.7%. The Drip halves every 26 weeks, next on April 7, 2027, and ends in October 2028. A day's reward vests over 30 days, and withdrawing forfeits the part still vesting. The Drip is a reward, not a share in anything, and $BORRO can be worth nothing.

Dollars without selling. Lent stock can also be posted to borrow USDG: up to 62.5% of its value for SPY, QQQ and NVDA, and 38.5% for the other six. The shares keep earning rent while they are posted. You keep the position and owe the loan, so there is no sale and no exit from the stock. One click also opens a leveraged long: your USDG and a flash loan buy the stock, the stock is lent to its vault, and the debt is borrowed against it, all in one transaction. That goes up to 1.8x on SPY, QQQ and NVDA and 1.35x on the rest, and the whole position earns rent while it is open.

If you hold dollars. USDG lent on Borro goes into its USDG vault, which lends to people borrowing against their stock. The interest floats with how much is borrowed, which today is almost nothing, and USDG lenders share 40% of the Drip. A new $1,000 of USDG would earn about 255% a year at today's rate, falling as deposits grow, on the same terms as above.

If you want to short. One transaction borrows real stock tokens from the lenders, sells them into the pool and holds the dollars. The sale money and your deposit sit in the Steakhouse USDG vault, earning about 4.5% a year at today's rate while the short is open. You pay rent for as long as it is open, and 0.10% of the sale when it opens. You can borrow stock worth up to 62.5% of what you post, or 77% for SPY and QQQ. Over a weekend, while the feeds pause, the Weekend Desk can sell cover against the gap at Monday's open once USDG lenders fund its pool. Today that pool is empty, so no cover is on sale.

What it costs, and what can go wrong. Borro keeps 10% of rent and of USDG interest, and 0.10% of each short's sale, and spends it buying back and burning $BORRO. Rent floats, and a quiet stock pays its lenders nothing. A loan or a short past its limit is closed, with a bonus of up to 15% to whoever closes it. Stock on loan cannot be withdrawn until the short closes, so a fully lent vault makes you wait. If a price jumps past a short's limit before it can be closed, over a weekend for instance, the shortfall falls on that stock's lenders. Borro's own contracts are reviewed and tested and not yet audited by an outside firm, and Borro has applied to the Arbitrum Security Program to get that done. Morpho, Chainlink, the pools and the token's issuer can fail too.

How it compares. Selling the stock gets you dollars and ends the position. Longbow, the chain's USDG lender, reports $3.8 million supplied across 63 markets. Its earn vaults take USDG and WETH, and stock tokens are collateral for USDG loans: you can borrow there against your stock, and it opens leveraged longs too, but nobody pays you to lend the stock itself, and it offers no way to short. Perps on Lighter and Arcus give leverage and shorts without holding any stock, and you pay or earn funding every hour. On 15 of the 16 stock perps we checked, longs paid on balance over the 30 days to October 15, from about 3.5% to 15% a year. A perp never holds the stock. If you want the stock itself, and to be paid for lending it, that is what Borro is for.

Nothing here is advice, and nothing is promised. Read the Rules page, check the contracts, and lend or borrow only what you can leave in place for a while.
