Spark Review 2026
Last updated: March 2026
Quick Summary
Spark (formerly Spark Protocol) is the lending arm of MakerDAO/Sky ecosystem, allowing users to borrow DAI at the Dai Savings Rate while using a wide range of crypto collateral types.
Table of Contents
Overview
Spark Protocol is the lending platform created by the Sky ecosystem (formerly MakerDAO), designed to be the primary interface for DAI and USDS lending and borrowing. Built on a fork of Aave V3, SparkLend offers familiar lending mechanics with the unique advantage of direct integration with Sky's stablecoin infrastructure. The protocol features competitive DAI borrowing rates often set below market through Sky governance, the DAI Savings Rate (DSR) for passive DAI holders, and sDAI as a yield-bearing stablecoin. Spark has rapidly grown to become one of the largest lending protocols by TVL.
Pros & Cons
Pros
- ✓Borrow DAI at favorable rates
- ✓Integrated with MakerDAO ecosystem
- ✓Dai Savings Rate for depositors
- ✓Governance-aligned incentives
Cons
- ✗Limited to DAI borrowing primarily
- ✗Smaller market compared to Aave
- ✗Dependent on MakerDAO governance
SparkLend Markets
SparkLend operates as a full-featured lending and borrowing protocol forked from Aave V3. Users can supply collateral including ETH, wstETH, rETH, WBTC, and other major assets to borrow DAI and USDS at competitive rates. The Aave V3 codebase provides efficiency mode (eMode) for correlated assets, isolation mode for new listings, and portal functionality. What distinguishes SparkLend is its direct connection to the Sky protocol, allowing DAI to be minted directly from SparkLend positions at rates set by Sky governance, often significantly below market borrowing rates.
DAI Savings Rate & sDAI
Spark integrates the DAI Savings Rate (DSR), which allows DAI holders to earn yield simply by depositing into the DSR contract. The rate is set by Sky governance and has been highly competitive, often exceeding rates offered by traditional savings accounts. sDAI is the tokenized representation of DAI in the DSR, automatically accruing yield. sDAI can be used throughout DeFi as a yield-bearing stablecoin, providing passive income while being used as collateral or in liquidity pools. This creates a compelling reason to hold DAI over other stablecoins.
Sky Ecosystem Integration
Spark operates within the broader Sky (MakerDAO) ecosystem, with key parameters like borrowing rates and the DSR set by Sky governance. This tight integration means Spark benefits from Sky's deep liquidity and battle-tested smart contracts. The relationship also means Spark can offer capabilities that independent lending protocols cannot, such as below-market DAI borrowing rates subsidized by Sky's revenue. The transition from MakerDAO to Sky branding has been gradual, with the protocol maintaining its core functionality while expanding to support new products and strategies.
Risk Management
Spark inherits Aave V3's proven risk management framework including liquidation mechanisms, oracle integration, and supply/borrow caps. Additional risk management is provided by Sky governance, which sets conservative parameters for DAI minting through SparkLend. The protocol uses Chainlink oracles supplemented by additional oracle sources for critical price feeds. As a fork of one of the most audited codebases in DeFi, Spark benefits from extensive security review, though it also introduces its own code that has been independently audited.
Future Development
Spark is positioned to be a central piece of the Sky ecosystem's expansion. Future developments include support for additional collateral types, cross-chain deployment to bring DAI lending to more networks, deeper integration with Sky's SubDAO structure, and the expansion of sDAI as a cross-chain yield-bearing stablecoin. The protocol is also exploring real-world asset (RWA) integration through Sky's existing RWA vaults. As Sky continues its rebranding and restructuring, Spark is expected to serve as the primary user-facing lending product.

Final Verdict
With a rating of 4.5/5, Spark is best suited for dai-focused users. Spark (formerly Spark Protocol) is the lending arm of MakerDAO/Sky ecosystem, allowing users to borrow DAI at the Dai Savings Rate while using a wide range of crypto collateral types.
Frequently Asked Questions
Why are Spark's DAI borrowing rates so low?
Sky governance can set SparkLend's DAI borrowing rate independently of market conditions because DAI is minted directly by the protocol. Sky subsidizes low rates to encourage DAI adoption and usage, funded by revenue from the broader Sky ecosystem.
What is sDAI?
sDAI is the tokenized version of DAI deposited in the DAI Savings Rate contract. It automatically accrues yield without any action required. You can use sDAI across DeFi like any other token while earning the DSR yield passively.
Is Spark the same as Aave?
Spark is built on a fork of Aave V3's smart contracts, so the lending mechanics are similar. However, Spark is governed by Sky (MakerDAO), offers unique DAI-specific features, and has different risk parameters and asset listings. They are separate protocols.
