At a glance
Spark Protocol ↗ and MarginFi (mrgn) ↗ target different corners of the lending market. Spark is a $4B TVL multi-chain lending protocol forked from Aave v3 ↗, embedded in the Sky (MakerDAO) ecosystem, and designed around DAI/USDS with governance-driven rates. MarginFi is a $0.4B TVL Solana-native money market with cross-collateral pools and risk-tiered assets. The choice largely comes down to ecosystem: Ethereum-side versus Solana-side.
Key differences
- TVL: Spark holds $4B in total value locked—ten times MarginFi’s $0.4B. This liquidity depth translates into tighter spreads and higher borrowing capacity on Spark.
- Chain coverage: Spark operates on Ethereum, Gnosis, and Base. MarginFi is exclusive to Solana. Multi-chain users will find Spark’s reach broader; Solana loyalists must look to MarginFi or alternatives.
- Lending mechanism: Spark, as an Aave v3 fork, uses overcollateralized lending pools with predictable DAI/USDS rates set by Sky governance. MarginFi employs global cross-collateral pools and risk tiers, allowing a wider range of collateral types and more flexible borrowing but with the trade-offs of cross-collateral contagion.
- Launch and maturity: MarginFi launched in 2022, giving it an extra year of live operation, though Spark (2023) has accumulated more TVL quickly thanks to Sky’s ecosystem.
- Audits: Both have two audits. Spark was reviewed by ChainSecurity and Cantina; MarginFi by Ottersec and Halborn. Neither has suffered a public exploit in this data set.
Security and track record
Spark’s audits (ChainSecurity, Cantina) and MarginFi’s (Ottersec, Halborn) are both recent and cover their respective codebases. Neither protocol has disclosed a security incident. Spark inherits some battle-testing from Aave v3’s architecture, which has been live since 2022 and withstood multiple market events. MarginFi’s Solana-specific design hasn’t been battle‑tested across chains, but its risk-tiered pool model adds an extra layer of asset segregation. Overall, both appear sound; the more meaningful risk factor is the collateral types each accepts.
Fees and costs
Neither protocol’s fee structure is disclosed in our data. Spark’s borrow rates on DAI/USDS are set by Sky governance and can be checked on spark.fi. MarginFi’s borrow/supply APYs are market‑driven and visible on marginfi.com. For current fee comparisons, refer directly to those dashboards.
Which should you choose
- Pick Spark if you need deep DAI/USDS liquidity, operate on Ethereum‑L2s or Gnosis, or want a lending market tightly integrated with the Maker/Sky ecosystem. Its $4B TVL and Aave v3 heritage provide assurance.
- Pick MarginFi if you are already on Solana and want a native money market with high‑capital‑efficiency cross‑collateral pools and risk tiers. The $0.4B TVL is meaningful for Solana DeFi, though smaller than Ethereum alternatives.
Verdict
Context‑dependent: the decision hinges on your preferred chain. Spark dominates in TVL and multi‑chain coverage, making it the safer bet for Ethereum users. MarginFi remains the leading Solana‑native money market by TVL and feature set. There is no universal winner; match the protocol to your ecosystem.
