3F vs Loop: RWA leverage or ETH carry trades? (2026)

3F and Loop both use leverage, but they serve different trades. 3F automates a position in a tokenized real-world asset: a user selects a vault and leverage level, while the protocol buys the asset, posts it as collateral and borrows stablecoins. Its vaults sit on Morpho markets, where USDC or USDT lenders supply the other side of the market. The project also describes bridge facilitation and automated liquidations.

Loop is a narrower lending market for Ethereum carry trades. Users deposit liquid restaking derivatives and other long-tail assets, including Pendle LP tokens, as collateral to borrow ETH. That borrowed ETH can increase yield and points exposure. The difference is the underlying strategy: tokenized RWA exposure and stablecoin borrowing with 3F, versus leveraged ETH carry trades with Loop. Neither removes the risks of leverage, collateral price changes or liquidation.

3F reports about $40 million in TVL, far more than Loop’s roughly $86,000. That is a substantial difference in reported deposits, but it does not guarantee that a particular vault has enough liquidity for your needs. 3F’s app is in private beta, so access is limited; its homepage gives a Q4 2026 timeline. Its institutional access is described as whitelisted.

Loop is live and has operated since mid-2024, giving it more operating history. It is deployed on Ethereum, XDC, BNB Chain and Scroll, while 3F lists Ethereum only. Loop’s low TVL may limit liquidity depth, and the homepage could not be fetched, leaving its documentation and parameters unclear. Before choosing either, check current market liquidity and whether you can access the specific vault or collateral market. TVL and chain count alone do not establish that a position is suitable.

Neither protocol publishes fees, borrow rates or liquidation penalties. Those costs matter because borrowing expenses can affect a leveraged position’s returns, while liquidation terms determine what happens if collateral value or market conditions move against you. 3F says its maximum yield and leverage figures are not a fee schedule. Current rates and terms should be checked in the documentation or app before committing funds; Ethereum gas also applies to 3F actions, and gas costs apply on whichever chain you use with Loop.

Both products carry smart-contract, collateral and liquidation risk. 3F adds dependencies on Morpho markets, tokenized asset issuers, price oracles, bridge facilitators and liquidators. Loop’s long-tail collateral can add risks from the underlying restaking protocols and Pendle pools, including depegs. High leverage can make losses and liquidations happen quickly. Do not treat an audit listing or a larger TVL figure as a guarantee of safety.

Choose 3F if your intended trade is leveraged exposure to tokenized real-world assets, or if you want to supply stablecoins to borrowers using those strategies. Its reported TVL is much larger, and its product automates the collateral-and-borrowing loop. The trade-off is limited access: the app is in private beta, and you should verify the project’s linked audits and risk terms before using it.

Choose Loop if you are experienced with ETH carry trades and specifically want to borrow ETH against liquid restaking derivatives or other long-tail collateral. Its four-chain presence and operation since mid-2024 may suit users who value those options, but its TVL is small and its audit details are not published. If you need transparent, published fee terms or want to avoid leverage and liquidation risk, neither is an obvious fit based on the information available.
