One reservoir, not many cups

Magma is cross-margin lending. Supply WETH, USDC, USDT, DAI — whatever you hold — and it all flows into one connected reservoir rather than sitting in separate, walled markets. Suppliers earn interest off the heat the borrowers generate. The deeper the reservoir, the more it can lend, and the rate moves with how much is drawn.

• ▸Markets: WETH · USDC · USDT · DAI
• ▸Supply earns a utilization-driven yield
• ▸Every enabled asset counts as collateral, together
• ▸Borrow any listed asset against the whole

One health factor governs all

This is the difference that matters. Your entire supplied portfolio backs your entire debt under a single shared health factor — strength in one asset shores up exposure in another. You borrow against the sum, not asset by asset. It is capital that breathes as one body instead of a row of isolated cells. (For risk walled off to a single pair, that is Lava.)

The edge, and the Cascade

Over-collateralized by design: you may only draw so far before the molten line. Let your health factor fall below 1.0 and the position is over the edge — any keeper can trigger the Cascade, repaying part of your debt and seizing collateral at a liquidation bonus. The penalty is split: a slice keeps liquidators honest, a slice flows back to suppliers. Yield-bearing collateral lifts your health factor as it appreciates, grinding the position back from the edge on its own.
