Dumpy.fun

Dumpy.fun is a Solana app for shorting memecoins: you make money if the token's price falls. It was built by Save N/A$0.1670.0% (formerly Solend), one of Solana's oldest lending apps. It opened as a beta, behind a password, in late July 2024. There are no futures involved. The app borrows the real token from Save's pools and sells it through Jupiter JUP$0.260+4.4%. You profit if you can buy it back cheaper later.

As of October 2026 the site is still online. But its X account has not posted since June 2025, and Save's docs no longer mention it. Treat it as a dormant side project of Save, not one still being built.

How to short memecoins on Solana with Dumpy.fun

A short here is a borrow-and-sell trade. You put up collateral. The app borrows the token against it and sells it at once for stablecoins.

The whitepaper sets out three steps:

1. You deposit USDC or SOL as collateral.
2. The app borrows the token you picked from Save and swaps it on Jupiter.
3. When you close, it buys the token back and repays the loan. If the price fell, you keep the difference.

Leverage comes from flash loans, and the whitepaper's examples go up to 2x. Bankless's August 2024 walkthrough shows the beta. You got a password from the project's Telegram, linked a wallet such as Phantom and picked a token. Then you set size and leverage on a slider, pressed "DUMP", and tracked the trade in an "Active dumps" tab.

Because the short is a real loan, two things work against you. You pay interest on the borrowed token. And if the price rises far enough that your collateral no longer covers the debt, you get liquidated.

Which memecoins can you short on Dumpy.fun?

At launch the beta listed a handful of large Solana tokens, including WIF, WEN, BONK, W and SOL (Bankless). The team added tokens by community vote. By August 2024 the list had grown to 11 memecoins, according to Yellow.

The team also promised permissionless listings, so that brand-new tokens could be shorted from day one. We found no public sign that this shipped. A token can only be shorted if Save holds enough of it to lend, so the market list depends on what holders deposit.

Who earns on the other side: lenders and squeezy.lol

Every short needs someone to lend the token. Here the lenders are holders who deposit their tokens into Save. They earn the interest that short sellers pay. The more people want to short a token, the higher that rate goes. The whitepaper calls this "onchain PvP".

In August 2024 the team announced squeezy.lol, a sister site with a "squeeze explorer". It shows which tokens are most shorted, and the price at which those shorts get wiped out (Yellow). The idea is simple. If buyers can see where a pile of shorts will be liquidated, they can try to push the price there and force them shut. The team chose to publish this on purpose, and it works against the people shorting.

Is there a Dumpy.fun token? DUMP and the airdrop

DUMP is a joke token that the whitepaper says is meant to go to zero. It was meant to show the product working on itself. Early beta users were told they would get DUMP in an airdrop (The Defiant, July 2024).

Some exchange explainers say DUMP would share fees and carry votes. We could not find these plans in any primary source. As of October 2026 we found no official word that DUMP has launched or that the airdrop went out. Be wary of any token that claims to be DUMP unless Save or the dumpy.fun account confirms it.

Is Dumpy.fun still active?

There is no shutdown notice. But there is no sign of new work either. Here is what we found in October 2026:

• dumpy.fun still loads and describes the product as "Powered by Save".
• The @dumpydotfun X account last posted in June 2025.
• Save's documentation lists lending, borrowing, leveraged longs and shorting on Save itself, but has no Dumpy.fun page.
• Save's own X account was still posting in October 2026, but none of the recent posts we reviewed mention Dumpy.fun.

Before you deposit, check that the token you want is still listed and that Save has enough of it to lend.

Who should use Dumpy.fun?

Dumpy.fun suits experienced Solana traders who want to bet against a specific large memecoin with real borrowed tokens rather than a futures contract. They also need to watch the position closely. It is a poor fit if you can't monitor trades through a fast rally, or if you want to short a token launched this week. You can only short what Save has in its pools, and borrow costs rise when everyone wants the same short.

Memecoin holders who are long-term bullish sit on the other side. Depositing into Save's pools pays them the borrow interest from short sellers, at the cost of Save's lending-protocol risks.

Is Dumpy.fun safe? Risks of shorting memecoins

The main risk is the trade itself. Memecoins can double in hours with no news, and there is no cap on what a short can lose as the price rises. Liquidation protects the lender, not you. If the price climbs past your line, the trade is closed and your collateral takes the hit. squeezy.lol shows those lines to everyone, so crowded shorts can be hunted on purpose. Interest also builds while you wait, so you can lose money even if the price falls in the end.

The code risk sits with Save. Dumpy.fun has no lending program of its own; it sends trades through Save's program and Jupiter.

• Audits. Save's security page lists a Kudelski Security full audit of the Solend lending contracts, dated September 2021, and a Sec3 automated scan. We found no public audit covering the Dumpy.fun front end or its flash-loan leverage flow.
• Upgrade control. Save's access-control docs say the team holds the program's upgrade authority keypair and the lending-market owner key, with no timelock. That means the team can change the code without a waiting period. We could not confirm the current on-chain authority for this refresh.
• Past incidents. In November 2022 an attacker manipulated the USDH price oracle to drain about $1.26 million from three Solend isolated pools, leaving bad debt that the DAO later voted to cover (The Block). Thin memecoin markets are exactly where oracle and liquidity risk is highest.
• Product risk. Because development has gone quiet, bugs or delisted markets may not be fixed quickly.

Dumpy.fun alternatives for shorting memecoins

The closest alternative is Save itself. Its docs list shorting as a core feature. You can borrow a listed token against collateral and sell it yourself. It is the same trade without the one-click screen. You get more control, but you handle the swap and the leverage by hand.

The other route is perpetual futures (perps) on memecoins, offered by big exchanges and some Solana perp DEXs. Perps don't need anyone to lend the token, so they can list more tokens and offer more leverage. But you trade a contract price, not the real market, and you pay funding instead of interest. A Dumpy.fun short sells real tokens into the real market, but you can only short what Save can lend.

Dumpy.fun and Save (formerly Solend)

Save started as Solend in 2021 and rebranded to Save in July 2024. It launched Dumpy.fun alongside the rebrand (The Defiant). Save also offers saveSOL, a liquid staking token that still appears in its app. Dumpy.fun was the fun, meme-themed part of that relaunch. It turned Save's pools into a one-click way to short, and gave holders of those tokens a reason to lend them out.
