Spark Protocol (spark.fi) is a MakerDAO/Sky-ecosystem lending and savings product launched August 18, 2023, built on Aave V3’s SparkLend fork — providing ETH, wstETH, and other asset borrowing against DAI/USDS stablecoin at competitive rates linked to Maker’s DAI Savings Rate (DSR), with deposited DAI earning the DSR directly on Spark, and sDAI/sUSDS (savings DAI and savings USDS) as yield-bearing stablecoin wrappers that can be used across DeFi — with a planned SPK governance token to be distributed to pre-launch users once Maker/Sky completes its governance separation process, rapidly growing Spark to multi-billion dollar TVL as the official lending interface for Maker’s stable dollar ecosystem.
How It Works
- SparkLend — Spark’s core lending market (SparkLend) is a fork of Aave V3, allowing users to supply ETH, wstETH, WBTC, rETH, and others as collateral and borrow DAI/USDS against them. Interest rates are linked to Maker’s stability fee and DAI Savings Rate.
- DAI Savings Rate integration — Depositing DAI into Spark’s savings module earns the DAI Savings Rate (DSR) natively. Users receive sDAI (savings DAI) — an ERC-4626 yield-bearing token that automatically accrues DSR yield.
- USDS and sUSDS — After Maker’s “Endgame” rebrand to Sky Protocol in 2024, DAI was accompanied by USDS (Sky Dollar) and sUSDS (savings USDS). Spark provides access to both DAI/sDAI and USDS/sUSDS savings products.
- Maker/Sky integration — Spark draws its DAI supply directly from Maker’s D3M (Direct Deposit Dai Module), allowing Spark to borrow large quantities of DAI at the DSR for relending. This means Spark’s DAI supply can expand rapidly without requiring traditional LP deposits.
- Multi-chain — Spark has deployed on Gnosis Chain and Base in addition to Ethereum mainnet.
- SPK airdrop — SPK governance tokens are planned for retroactive distribution to Spark users (based on points earned by depositing/borrowing on Spark), allowing Spark to eventually operate independently from Maker governance.
Tokenomics
| Parameter | Value |
|---|---|
| Planned token | SPK (Spark governance token) |
| Distribution | Retroactive airdrop to pre-launch users (points-based) |
| Current governance | Controlled by MakerDAO/Sky governance |
| sDAI | ERC-4626 savings DAI (earns DSR, ~5% in 2023–2024) |
| sUSDS | ERC-4626 savings USDS (earns Sky savings rate) |
Use Cases
- DAI/USDS borrowing at competitive rates — Borrow stablecoins against ETH or liquid staking tokens.
- DSR yield — Earn the DAI Savings Rate on sDAI deposits (highest native stablecoin APY in DeFi during 2023–2024 when DSR was 5–8%).
- sDAI as DeFi collateral — sDAI is accepted as collateral and in LP pairs across many DeFi protocols, enabling yield while maintaining collateral flexibility.
History
- 2023-08-18 — Spark Protocol launches SparkLend on Ethereum mainnet. The protocol is built by Phoenix Labs (a Maker ecosystem contributor) and approved via MakerDAO governance. Initial markets include ETH, stETH, DAI, USDC, and USDT.
- 2023-Q3 — DAI Savings Rate is raised by MakerDAO to 5% (subsequently to 8%), dramatically increasing sDAI’s appeal as a yield-bearing stablecoin. Spark TVL grows rapidly as users deposit DAI to earn DSR natively on Spark.
- 2023-Q4 — Spark becomes one of the top 5 Ethereum lending protocols by TVL. sDAI’s integration as collateral on Aave, Morpho, and MakerDAO vaults itself creates recursive demand.
- 2024 — MakerDAO rebrands to Sky Protocol. DAI is supplemented by USDS (Sky Dollar) and Spark adds sUSDS as its savings product. The Endgame plan outlines Spark gaining increasing autonomy from Sky governance.
- 2024 — Spark expands to Base chain. SPK token airdrop program is announced for pre-launch users, with retroactive points tracked for all Spark interaction. SPK has not yet launched publicly as of early 2026.
- 2024–2025 — Spark maintains multi-billion dollar TVL. sDAI becomes widely used across DeFi protocols as a yield-bearing stablecoin — arguably Spark’s most significant contribution to the ecosystem.
Common Misconceptions
“Spark is just an Aave fork with no differentiation.”
Spark’s key differentiator is its direct integration with Maker’s DAI Savings Rate and D3M borrowing module. This allows Spark to offer DSR-linked stablecoin borrowing rates and native sDAI yield that is impossible to replicate without Maker integration. Spark also does not require independent liquidity to scale its DAI supply — it draws from Maker’s DSS.
“sDAI is a rebasing token.”
sDAI is an ERC-4626 vault token. Rather than rebasing (adjusting each holder’s balance), sDAI’s price increases over time relative to DAI as interest accrues. 1 sDAI is always worth more than 1 DAI (and more each passing day).
Social Media Sentiment
Spark gained enormous positive attention in 2023–2024 as sDAI’s native 5–8% yield made it the most attractive fiat-denominated savings product in DeFi during a period when TradFi money markets were at similar rates. The MakerDAO backing (now Sky) provides institutional credibility. The SPK airdrop has kept a loyal points-farming user base engaged. Critics note that Spark’s most valuable feature (DSR yield) is entirely dependent on MakerDAO governance decisions, making it not truly independent.
