MarginFi

MarginFi tracks all of your collateral and borrowed positions in a single cross-margin account rather than isolating them per asset, which generally gives more capital-efficient borrowing power to users holding diversified collateral — at the cost of a different risk shape than isolated lending. The protocol evaluates your combined positions together to calculate overall health and liquidation risk.

What it’s for

MarginFi is used for the standard lending use cases — supplying assets for yield, or borrowing against posted collateral — with the cross-margin design intended to let a diversified collateral set be evaluated together rather than asset by asset.

Fees

Supply and borrow rates float with each asset’s utilization, same as other Solana money markets — check the app for current rates. There’s no separate account-level fee beyond the interest paid by borrowers to suppliers.

Pros and cons

• Pro: cross-margin design can unlock more borrowing power from a diversified collateral set than isolated per-asset lending would.
• Pro: established backend infrastructure other apps build lending or leverage features on top of.
• Con: because positions are evaluated together, a sharp move in one asset can affect liquidation risk on your whole account, not just that position.
• Con: a concentrated (non-diversified) collateral position doesn’t get the cross-margin benefit and still carries the shared-account risk shape.

Track record

MarginFi has been an established part of the Solana lending landscape for several years and is commonly used both directly and as backend infrastructure by other apps building lending or leverage features on top of it.

Risk considerations

Cross-margin design has a specific tradeoff worth understanding: because your positions are evaluated together, a sharp move in one asset can affect your liquidation risk on the whole account, not just that one position. This can cut both ways — diversification can also reduce it — but it’s a meaningfully different risk shape than isolated per-asset lending.
