Spark, a lending protocol from the Sky ecosystem (formerly MakerDAO's lending arm), recorded a 190 percent increase in active loans over the past 180 days, reaching approximately $2.9 billion. This positioned Spark as the fastest-growing lender among the top 10 DeFi protocols by active loans, according to on-chain data.
This expansion occurred as the broader decentralized finance lending market contracted by an estimated 30 percent during the same six-month period. SparkLend's share of outstanding loans across major venues rose to 10.4 percent in Q2 2026 from 4.3 percent in Q1.
Ethereum borrowing on the platform increased 247 percent since March 2026. A primary driver of this increase was USDS borrowing, which grew from $188 million to $917 million. This single stablecoin accounted for nearly half of SparkLend's total loan increase.
Total value locked (TVL) in SparkLend reached roughly $5 billion in Q2, with deposits climbing to $5.03 billion, marking a 69 percent quarter-over-quarter jump. DefiLlama data shows SparkLend's TVL at approximately $4.96 billion, making it the third-largest lending protocol tracked by the aggregator.
SparkLend added over $1.3 billion in locked value during the summer months, from approximately $3.6 billion at the close of May 2026. The total market size of supplied assets on Ethereum reached $7.39 billion as of mid-September 2026.
Operationally, SparkLend reported net income of around $3.3 million for Q2. Distribution rewards linked to USDS savings products contributed $4.88 million, a 43 percent increase from the previous quarter. Monthly operating costs remained flat at $1.1 million.
Three factors supported SparkLend's growth: competitive stablecoin borrowing rates, deep liquidity provided by the Spark Liquidity Layer (SLL), and increasing institutional interest. The SLL functions as an institutional-grade liquidity backbone for the protocol.
Spark allocated $210 million specifically for BTC-collateralized loans, with $150 million already deployed. These loans maintain an average collateralization ratio of approximately 148 percent, signaling the protocol's focus on attracting institutional capital.
SparkLend operates as a curated fork of Aave V3. This architecture allows it to use battle-tested smart contract security while implementing its own credit parameters and risk frameworks. The protocol's native stablecoin, USDS, deeply integrated into the Sky ecosystem, enables it to offer borrowing rates that competitors relying on third-party stablecoins cannot easily match.
Spark also absorbed capital flows following an exploit on a competitor, Aave. Over $1.7 billion in new deposits flowed into SparkLend within five days of the incident, with active loans growing by approximately $500 million during that period, according to DefiLlama data.
The protocol has announced plans to deprecate its deployment on Gnosis Chain, confirming its exclusive focus on Ethereum. This move aligns with Spark's strategy to capture a larger share of the on-chain lending market.
Spark's expansion positions it to capitalize on the estimated $33 billion off-chain crypto lending market. This segment of capital is actively seeking on-chain alternatives following the collapses of centralized lenders such as Genesis, BlockFi, and Celsius, which have prompted a shift toward decentralized solutions.
SparkLend's rapid growth and strategic focus show a clear divergence in the DeFi lending landscape, where protocols with strong liquidity, competitive rates, and institutional appeal are gaining ground even as the overall market contracts.
