Morpho on herrenlos: isolated markets, one pair at a time

herrenlos's Lending tab aggregates on-chain money markets from Morpho, Aave, and Compound III — you compare the real markets side by side and act on them from your own wallet. This post is about Morpho specifically: how its market model works, what the app shows you, and precisely what's wired up today.

What Morpho is

Morpho organises lending into isolated markets. One market is exactly one pair: a collateral asset on one side, a loan asset on the other. WBTC against USDC is one market. wstETH against USDC is a different market. They don't share liquidity, they don't share risk, and they don't share parameters.

That isolation is the whole point, and it's why the numbers on a Morpho row are per pair rather than per asset:

• LLTV — the liquidation loan-to-value — is a property of the pair, not of the collateral token. The same collateral can sit in two markets at two different LLTVs, because each market was created with its own risk parameter. On the market page herrenlos shows this as Max LTV.
• Utilisation is also per pair: it's how much of that market's supplied loan asset is currently borrowed. A busy USDC market next door doesn't move it.
• Rates follow utilisation within the market. Supply and borrow APY are set by the pair's own supply/demand curve, not by a pool-wide average.

Compare that with the other two providers herrenlos lists: Aave is pooled (supply a reserve, it becomes collateral, borrow from shared liquidity), and Compound III is one borrowable base asset surrounded by collateral-only assets. Three different shapes, none strictly better — which is exactly why the app shows all three and lets the market page be the source of truth.

A practical consequence of isolation: a Morpho market can exist with no collateral asset yet — nothing has been listed to borrow against it. herrenlos shows those honestly as loan-only rows rather than pretending a pair exists.

What you can do on herrenlos today

Compare markets. Morpho markets appear in the Lending markets table alongside Aave and Compound, each tagged with a provider badge, and there's a provider filter if you want to look at Morpho alone. herrenlos lists Morpho markets across every chain Morpho reports.

Read the market properly. Open a market and you get a detail header plus live stats straight from the protocol: supply APY, borrow APY, total supplied, available liquidity, Max LTV, and a utilisation read-out. Where a rate history series is available for that market, herrenlos draws an APY history chart underneath; where there's no series, it renders nothing at all rather than an empty frame.

Act on it. Interactive Morpho actions are live on Ethereum, Base, Arbitrum, Optimism, and Polygon — the chains where the app can route your wallet and where the contracts the SDK bundles through are actually deployed. The four actions are:

• Supply collateral — deposit the market's collateral asset to back future borrows.
• Borrow — draw the loan asset against that collateral.
• Repay — pay debt back down.
• Withdraw collateral — take collateral back out.

Markets on chains outside that list stay read-only: you still see the market and any position, and the actions are disabled with a clear note, instead of the app offering a button that would fail.

See your position. Your supplied collateral, your debt, and your position's health appear on the market page, with the same Health factor label the rest of the lending surface uses.

Non-custodial, and no lending fee

Every action is built as an unsigned transaction and handed to your wallet to sign. herrenlos never holds your funds, never signs for you, and there's no account or KYC.

There is also no herrenlos fee on lending — no origination fee, no router fee, no fee recipient. The transaction the app submits is the protocol's own feeless bundle. That's a deliberate product decision, not a promotional rate that expires.

Your keys never leave your wallet. Non-custodial isn't a setting — it's the only way herrenlos works.

Honest about the limits

• Operator kill-switches. Supply and borrow sit behind lending execution flags (NEXT_PUBLIC_LENDING_SUPPLY_EXECUTION_ENABLED / NEXT_PUBLIC_LENDING_BORROW_EXECUTION_ENABLED), shared across all three lending providers. When one is off, browsing and positions still work — only that action is disabled, with honest copy.
• You need a wallet on the right chain. Actions require a connected wallet switched to the market's chain; read-only browsing needs neither.
• Liquidations are real. Cross the market's LLTV and the position can be liquidated by anyone. herrenlos shows the parameters and your health — it does not manage risk for you, and it won't stop you from taking a thin one.
• We don't invent a net APY. Morpho's base supply and borrow APYs are shown as the protocol reports them. Where a reward-adjusted net rate isn't reported for a market, the app leaves it blank rather than inventing a number.
• A rate is a snapshot. APYs are live, but any figure is an estimate until a transaction settles.
• It's one of three providers, in beta. Sometimes an Aave reserve or a Compound Comet is the better fit — surfacing that side by side is the point.

Try it

Open Lending, filter to Morpho, and pick a pair to see its rates, LLTV and utilisation, then supply collateral or borrow against it. If you'd like the contrast, the Compound III post walks through the base-plus-collateral model, and the roadmap lays out where lending and the rest of herrenlos are headed.
