Lower risk — simple yield-bearing wrapper backed by DeFi's most battle-tested stablecoin protocol, but yield is governance-dependent and subject to significant rate changes
Top Risks
1
Spark Savings (sDAI/sUSDS) depends entirely on the Sky (formerly Maker) DSR/SSR rate, which is governance-controlled. Rate changes (e.g., the March 2025 cut from 6.5% to 4.5%) cause rapid TVL swings as yield-seekers migrate, creating reflexive inflow/outflow dynamics.
2
sDAI and sUSDS are ERC-4626 wrappers around DAI/USDS in the Savings Rate module. While the wrapper contract is simple, the underlying yield comes from Sky Protocol's complex lending, RWA, and PSM operations — a failure in Sky's backing directly impacts Spark Savings depositors.
3
At $1.2B TVL, Spark Savings represents a significant concentration of Sky Protocol's total DAI/USDS supply in the savings module. A sudden mass withdrawal could strain DSR module liquidity and force Sky governance to emergency-adjust rates.

Frequently Asked Questions
Is Spark Savings safe to use?
Spark Savings receives a B risk grade (22/100) from Hindenrank, where lower scores indicate lower risk. Lower risk — simple yield-bearing wrapper backed by DeFi's most battle-tested stablecoin protocol, but yield is governance-dependent and subject to significant rate changes Spark Savings lets you earn yield on DAI and USDS stablecoins by depositing them into the Sky (formerly Maker) Savings Rate module. You receive sDAI or sUSDS tokens that automatically appreciate in value as yield accrues, currently at 3.5-4.5% APY. With $1.2B in deposits and the battle-tested MakerDAO/Sky infrastructure behind it, Spark Savings earns a B+ risk grade. The main risks are governance-controlled rate changes that can swing dramatically, and the fact that your yield ultimately depends on Sky Protocol's complex lending and RWA operations.
What are the main risks of using Spark Savings?
The key risks identified for Spark Savings are: (1) Your yield rate is controlled by Sky Protocol governance and can change significantly. The rate was cut from 6.5% to 4.5% in March 2025. Rates could be cut to near-zero in a crisis, though your principal remains safe. (2) While the sDAI wrapper is simple, your yield comes from Sky Protocol's complex operations: lending, real-world assets, and the Peg Stability Module. A failure in these underlying operations could ultimately impact the savings rate. (3) sDAI is widely used as DeFi collateral, creating leveraged yield strategies. If rates are suddenly cut, leveraged positions unwind, which could cause temporary market disruption.
