Haven

This is Haven at haven.trade, a leverage trading app on Solana. It is not Haven Protocol (XHV), the Heaven launchpad or the HAVEN memecoin. Haven lets you go long or short with leverage, and it is built so your trade is not liquidated. It does this by resizing your loan for you as the price moves. Your loan sits on Marginfi LST$127.67+3.2%, the Solana lending app now called Project 0. Haven has no token. One founder built it, and he is named.

As of October 2026 the app and docs are still up. But Haven's X account has not posted in over a year, and its code has been taken off GitHub. Read the risk section before you deposit.

How Haven's no-liquidation leverage works

Haven calls its model "bracketed leverage", or "threshold-based constant leverage". When you open a position, you pick a target leverage and an LTV range with a lower and an upper bound. LTV is how much you owe compared with what your collateral is worth. Haven's automation watches it and steps in at either edge, per its docs:

• Boost rebalance. If price moves your way, LTV drops below the lower bound. Haven borrows more and adds it to your collateral, which brings your leverage back up.
• Repay rebalance. If price moves against you, LTV climbs past the upper bound. Haven sells some collateral to pay down the debt, which brings your leverage back down.

A lender liquidates you when LTV gets close to 100%. Haven cuts your debt long before that point, so a falling market shrinks the position rather than closing it. The docs add that boosts compound: each one grows the collateral, so the next boost is bigger.

Haven long, short and ratio strategies

The app has long, short and ratio trades on the token pairs it lists. It also has a simulator. The FAQ says this plays out random price moves toward a price you pick. Run it hundreds of times and you get a better guess. It helps you plan. It can't tell you the future.

You can add or take out funds after you open a trade. The trade just has to stay above $100. Marginfi sets the top leverage for each pair, not Haven. The FAQ admits these caps are low. It says more leverage often doesn't pay anyway, because of volatility decay.

Haven fees and referral program

Haven only charges on the amount it boosts or repays, not on the whole position, per its fee page:

What you pay in total depends on how often your trade gets resized. That comes down to how much the price swings and how wide you set your range. A tight range in a choppy market means more resizes and more fees.

The referral program pays you 15% of the fees from people you refer. They get 10% off their fees for good. Payouts go out every Friday at 08:00 UTC, in a token you pick.

Who Haven is for

Haven suits traders with a strong view on where an asset is heading over weeks, not hours. It fits people who want leverage on Solana tokens without a perp position that can be wiped out by one sharp wick. The docs give the same advice: trade with the trend, test your settings in the simulator, and keep your money in a few larger positions rather than many small ones.

It is a poor fit for range-bound markets, for active short-term trading, and for anyone who wants high leverage, since marginfi's caps are low. It is also a poor fit if you need a product that is clearly still being maintained (see below).

Is Haven safe? Risks, audit and status

"No liquidation" is not the same as "no loss". The trade-offs:

• Volatility decay. This is the main cost of the design, and the docs say so plainly. Each repay sells collateral after a drop, and each boost buys after a rise. In a market that swings up and down without trending, that cycle wears the position down. You can lose more than you would with ordinary leverage that never hits its liquidation price.
• Liquidation is unlikely, not impossible. The FAQ says Haven prevents liquidation "in 99.9% of cases". A gap move that is faster than the automation could still get through.
• Stacked protocol risk. The FAQ lists exploits or failures in Haven, marginfi or Jupiter, plus oracle and infrastructure failures, as risks. A bug in any of them affects your position.
• Custody. Haven describes itself as non-custodial. Only the position's owner can deposit or withdraw. The automation can only rebalance. The program address listed in the security docs is AutoyKBRaHSBHy9RsmXCZMy6nNFAg5FYijrvZyQcNLV. The docs don't say who can upgrade it, and we could not confirm the upgrade authority from an explorer for this update. If that is a single key, it is a material risk.
• Audit, and code that is no longer public. The security page says Hashlock audited the program, called Solauto, with "no remaining high-severity issues". The page doesn't say which version the audit covered. The report and the open-source code were both hosted at github.com/haven-fi/solauto. As of October 2026 that repository returns a 404, and the haven-fi GitHub organisation shows no public repositories. So you can no longer check the audit or the code from the links in the docs.
• Upstream changes. Marginfi rebranded as Project 0 in September 2025, and app.marginfi.com now redirects to the new app. Haven's docs still refer to marginfi, and the site footer still reads © 2025.
• Key-person risk. Haven's team page describes a single doxxed solo founder, Mitchell (@cheliosooo). In August 2026 Superteam Canada introduced him as a core protocol engineer at Perena, and his recent posts are about Perena and Kestrel. The official @haven_fi account has posted nothing in the past year.

None of this shows that Haven has shut down. But with no recent updates, no public code and the founder working elsewhere, treat it as a product that may not be actively maintained. Keep position sizes to match.

Haven vs perps and other no-liquidation leverage on Solana

• Perpetual futures on Jupiter JUP$0.260+4.4% or Drift Protocol DRIFT$0.013+0.3% offer far higher leverage, and you pay funding rather than rebalancing fees. But a position is closed if it reaches its liquidation price. Haven trades that cliff for gradual de-leveraging and volatility decay.
• Hylo sells xSOL, a leveraged SOL token that also has no liquidations. You hold one token rather than managing a position, but it covers SOL only. Haven works across the pairs marginfi supports.
• Kamino Finance KMNO$0.037+12.2% Multiply builds similar looped borrow positions, but it can be liquidated unless you manage the position yourself.
