MarginFi’s lending program now sits inside Project 0, which can share collateral across integrated venues. That may improve borrowing efficiency for diversified collateral.
It also means positions can share liquidation risk.
For the current user-facing product, start at Project 0. Older MarginFi app and SDK names do not describe the whole current product.
The marginfi program still powers the lending infrastructure.
What MarginFi’s cross-margin account is used for
Use MarginFi to supply assets or borrow against collateral. Its cross-margin design evaluates several positions together.
How MarginFi’s lending rates work
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.
See our head-to-head comparisons: MarginFi vs Kamino and MarginFi vs Save.
The cross-margin tradeoff: more capital efficiency, shared risk
- Pro: Diversified collateral may support more efficient borrowing.
- Pro: Other apps use MarginFi infrastructure.
- Con: A sharp move in one asset can affect the whole account.
- Con: Concentrated collateral gets little diversification benefit but keeps the shared-account risk.
MarginFi’s track record as lending infrastructure
MarginFi has been an established part of the Solana lending landscape for several years and now extends beyond a standalone lending app: Project 0’s official documentation describes cross-venue collateral and a unified account built on the marginfi lending program. That broader capability is useful, but it also means the risk surface is broader than a simple single-market supply-and-borrow position.
Risks specific to MarginFi’s shared-account design
Because positions are evaluated together, a sharp move in one asset can affect account-wide liquidation risk.
Diversification may help. Concentrated collateral gets less benefit from cross-margin and still carries shared-account risk. Read our lending risk and liquidation guide.
What to verify before borrowing on MarginFi
MarginFi’s cross-margin behavior is described in Project 0’s official documentation and can be compared with its live account and market state on Solana. Before borrowing, inspect the current health thresholds, collateral weights, and liquidation conditions for the exact account rather than relying on a generic description of cross-margin risk.
