One of Solana's original lending protocols (formerly Solend), running a main pool plus isolated pools for higher-risk collateral.
MarginFi's Solana lending program, now powering Project 0's unified margin account and cross-venue collateral model.

Save separates higher-risk assets into isolated pools. MarginFi combines positions in a cross-margin account. Save is easier to contain by pool. MarginFi can make diversified collateral more efficient, but shared account risk matters.
Save isolates pool risk; MarginFi shares risk across collateral
Save has a shared main pool for established assets and separate pools for higher-risk collateral. A bad asset is contained to its pool. MarginFi evaluates collateral and debt together in one account, which can provide more borrowing power when the collateral is genuinely diversified.
Track record: an original protocol versus established infrastructure
Save has operated since early Solana DeFi and has lived through several market cycles, including a large-position stress event. That history is useful context for why pool isolation and conservative collateral parameters matter. MarginFi has also operated for several years and is used directly and as infrastructure by other apps.
Isolation versus cross-margin capital efficiency
Save’s shared pool still carries correlated risk among its assets. Its isolated pools contain risk more narrowly. MarginFi can unlock more borrowing power from diversified collateral, but a sharp move in one asset can affect the whole account. This is a different risk shape, not a universal safety ranking.
Which fits which situation
Choose Save if you want your risk contained to a specific pool and prefer a protocol with a long, publicly stress-tested track record in exactly this kind of scenario.
Choose MarginFi if you hold genuinely diversified collateral and the cross-margin capital efficiency is worth the shared-account risk shape to you.
Both require the same discipline: know which pool (Save) or how concentrated your collateral is (MarginFi) before borrowing meaningfully.
Risk, plainly
Standard lending and liquidation risk applies to both — see our lending risk and liquidation guide and DeFi risk guide. Verify current pool assignments and account-health parameters directly on each platform before committing meaningful capital.
Frequently asked
Which is safer for a large, concentrated position?
Save's isolated pools contain a bad asset's risk to that specific pool, which is more straightforward to reason about for a large, concentrated position than a cross-margin account. MarginFi's cross-margin design means a sharp move in that one concentrated position can affect your entire account's liquidation risk, without the cross-margin benefit that diversified collateral would get.
Which has the longer operating history?
Save is one of the original Solana lending protocols, operating since early in Solana DeFi and through multiple market cycles including a well-documented large-position stress event. MarginFi has also been established for several years and is widely used as backend lending infrastructure by other apps, but Save's history in this category specifically runs longer.
Which gives more borrowing power against a diversified collateral set?
MarginFi, by design — its cross-margin account evaluates your combined positions together, which generally unlocks more capital-efficient borrowing from diversified collateral than Save's pool-based isolation.
