When interest rates rose globally in 2022-2023, DeFi stablecoin yields collapsed. But MakerDAO had a different mechanism available: the DAI Savings Rate (DSR) — a policy tool controlled by MakerDAO governance that pays DAI holders who lock in the Pot contract. MakerDAO raised the DSR to 5-8% (when US Fed rates were 5-5.25%), creating genuine yield on DAI comparable to US Treasuries but without traditional finance counterparty risk. sDAI is the tokenized representation of DAI in the DSR contract.
sDAI and the DAI Savings Rate
sDAI (Savings DAI) is an ERC-4626 tokenized vault — you deposit DAI and receive sDAI tokens that appreciate in value against DAI as the DSR accrues. Unlike traditional staking where you receive additional tokens, sDAI's exchange rate increases: 1 sDAI becomes worth 1.05 DAI after a year at 5% DSR. This design makes sDAI naturally composable — DeFi protocols can hold sDAI and automatically earn yield without managing rebasing mechanics.
The DSR's funding source: MakerDAO earns revenue from stability fees (interest on DAI loans), Real World Asset (RWA) investments (MakerDAO invested billions in US Treasuries and other RWAs), and other protocol income. This revenue funds the DSR payments. The DSR is set by governance vote to balance MakerDAO's income with competitive yield offerings.
sDAI integration: multiple DeFi protocols integrated sDAI as their preferred stablecoin — Balancer pools using sDAI, Aave markets with sDAI as collateral, Curve pools with sDAI. The composability means depositing to Spark earns DSR + any additional yield from the protocols using sDAI. This created a 'yield aggregation by default' effect.
- ✓sDAI: ERC-4626 vault — deposits earn DAI Savings Rate automatically
- ✓Exchange rate appreciation: sDAI value vs DAI grows continuously (no rebase)
- ✓DSR governance-set: MakerDAO votes adjust DSR based on competitive rates and income
- ✓5-8% DSR (2023): competitive with US Treasuries — landmark DeFi milestone
- ✓Funding source: stability fees + RWA investments fund DSR payments
- ✓DeFi composability: sDAI integrates with Balancer, Curve, Aave as yield-bearing stable
SparkLend: Competing with Aave
SparkLend (app.spark.fi) is a full lending market built by Spark Protocol, a SubDAO of MakerDAO. It supports supplying and borrowing ETH, WBTC, wstETH, USDC, DAI/sDAI, and more. SparkLend is a fork of Aave V3's codebase, benefiting from Aave's battle-tested security while using MakerDAO's liquidity infrastructure.
Key differentiator: SparkLend's DAI borrow rate is heavily influenced by MakerDAO's stability fee (cost to mint DAI), often making DAI borrowing on Spark cheaper than on Aave. For DAI-specific strategies — borrowing DAI to invest elsewhere, using it as leveraged stablecoin — Spark can be more capital-efficient.
Efficiency mode: Spark inherits Aave V3's eMode — correlated assets (USDC/DAI, ETH/wstETH) can be borrowed at much higher LTV (loan-to-value ratios) in efficiency mode. This enables leveraged staking strategies: deposit wstETH, borrow ETH in eMode at 90%+ LTV, swap ETH for more wstETH, repeat. The staking yield (4-5% on ETH) minus borrow cost creates leveraged return — with liquidation risk if ETH price falls.
- ✓SparkLend: Aave V3 fork under MakerDAO — DAI/sDAI integrated natively
- ✓Competitive DAI rates: DAI borrow often cheaper on Spark than Aave
- ✓eMode: 90%+ LTV for correlated asset pairs (ETH/wstETH, USDC/DAI)
- ✓Leveraged staking: borrow ETH against wstETH in eMode for leveraged yield
- ✓MakerDAO integration: SparkLend directly connects to MakerDAO's DAI supply
- ✓SPARK token: planned governance token for Spark SubDAO (launch pending)
