What is Spark?
Spark is a DeFi protocol that functions as an on-chain capital allocator, leveraging over $6.5 billion in stablecoin reserves from Sky (formerly MakerDAO).
The project is deployed on Ethereum, Arbitrum, Base, Optimism, Unichain, and Gnosis Chain, managing more than $3.97 billion in stablecoin liquidity and generating $191.16 million in annual revenue (as of June).
Spark’s key strengths:
🔥Deep liquidity: Supports instant USDS/USDC withdrawals with zero slippage.
🔥Multi-chain integration: Operates across multiple chains, increasing compatibility with the Ethereum Superchain.
🔥Transparency: Open-source smart contracts that have been audited.
Spark is developed by Phoenix Labs, co-founded by CEO Sam MacPherson. The project collaborates with the Sky Ecosystem, Aave, Morpho, Pendle, Lido, Curve, Arbitrum, Optimism, GnosisDAO, Base, Polygon, Ethena Labs, and 0xFluid.
A trusted platform in the community thanks to backing from Sky, Spark was first listed on Binance Alpha on June 17. Binance officially launched the SPK token at 16:00 UTC on June 17 following the HODLer Airdrops to the community.

Spark’s technology architecture
Spark functions as an on-chain capital allocation engine, connecting Sky’s stablecoin reserves with yield opportunities across multiple chains. The protocol uses open-source, audited smart contracts to ensure transparency and security.
Spark leverages more than $6.5 billion in stablecoin reserves from Sky and deploys them across DeFi protocols (like Aave, Morpho, Pendle, Curve), real-world assets (RWA), and CeFi platforms to optimize yield with low risk.
Capital allocation process:
👉Capital sources: Spark uses USDS and USDC from Sky's reserves to ensure deep liquidity.
👉Automated allocation: Through the Spark Liquidity Layer (SLL), funds are deployed into efficient liquidity pools across multiple chains, based on data from the Cross-chain SSR Oracle.
👉Instant liquidity: The Sky PSM enables slippage-free swaps between USDS and USDC, ensuring users can withdraw funds at any time.
👉Yield optimization: Spark seeks out the best yield opportunities from DeFi transaction fees to returns from RWAs, delivering competitive yields compared to the Dai Savings Rate.
Key features:
👉Transparency: All transactions are recorded on-chain and can be audited via the Spark Data Hub.
👉Scalability: Supports billions in liquidity across Ethereum, Arbitrum, Optimism, Unichain, Base, and Gnosis Chain.
👉Protocol integration: Connects with leading DeFi protocols to enhance capital efficiency.
Core technologies powering Spark:
👉Audited open-source smart contracts
👉Sky PSM for slippage-free USDS/USDC swaps
👉Cross-chain SSR Oracle for yield data on L2
👉Multi-chain integration, deep liquidity, and scalability
Spark’s DeFi products
Spark Savings – Yield accumulation from stablecoins
Spark Savings allows users to deposit stablecoins (USDS or USDC) to receive sUSDS, a token that represents a balance that accumulates value based on the Sky Savings Rate (SSR). According to the project's documentation, sUSDS is similar to sDAI in the Sky ecosystem and automatically accumulates yield based on the SSR, which is adjusted by Sky according to market conditions.
How it works:
Users deposit USDS/USDC via the interface at spark.fi and receive sUSDS.
sUSDS accrues value daily based on SSR, which is typically higher than the Dai Savings Rate.
Users can redeem sUSDS for USDS/USDC anytime through Sky PSM with zero slippage.
Key features:
Low-risk yield: Provides stable returns, ideal for conservative investors.
Multi-chain integration: sUSDS is deployed on Ethereum, Arbitrum, Optimism, Base, Unichain, and Gnosis Chain (per X post dated June 12, 2025).
Flexibility: Instant withdrawal, suitable for short-term liquidity needs.
SparkLend – Competitive USDS lending market
SparkLend is a decentralized lending market focused on USDS, allowing users to borrow USDS using assets like ETH or USDC as collateral. SparkLend utilizes Sky’s liquidity to offer efficient loans.
How it works:
Users deposit collateral (ETH, USDC) to borrow USDS from SparkLend.
Interest rates are optimized through capital deployment in DeFi and RWA, keeping borrowing costs low.
SparkLend is integrated with Aave and Morpho to enhance liquidity and performance.
Key features:
Low interest rates: Sky’s deep liquidity allows SparkLend to offer competitive borrowing rates.
Protocol integration: Connects with Aave and Morpho for optimized yields.
Security: Audited smart contracts ensure protocol safety.
Spark Liquidity Layer (SLL) – Automated DeFi liquidity
The Spark Liquidity Layer (SLL) is an automated liquidity layer that deploys USDS, sUSDS, and USDC into liquidity pools across various chains and DeFi protocols. SLL maximizes yield by allocating funds to the most efficient pools.
How it works:
SLL automatically allocates stablecoins into pools on Curve, Pendle, or Aave using data from the Cross-chain SSR Oracle.
Users provide liquidity via SLL and earn trading fees and DeFi incentives.
SLL supports Ethereum, Arbitrum, Optimism, Unichain, Base, and Gnosis Chain.
Key features:
Automation: Actively seeks best yield opportunities, reducing user management effort.
Multi-chain integration: Broad access to liquidity across chains.
Deep liquidity: Utilizes Sky’s $6.5 billion reserves.
Spark Data Hub – On-chain DeFi data platform
The Spark Data Hub is Spark’s core data product, designed to provide transparent on-chain data to support users and the community in tracking protocol performance and optimizing DeFi interactions.
Launched in May, Spark Data Hub serves as an information center, offering detailed metrics on liquidity, yields, and SPK token distribution campaigns. It reinforces Spark’s transparency and accessibility in decentralized finance.
Key objectives:
Data transparency: Offers accurate on-chain insights into Spark’s capital allocation and yield generation.
Community support: Empowers users, developers, and content creators with data for analysis or campaign building.
Engagement: Supports airdrop campaigns like Ignition (launched June 12), by providing reward and eligibility data.
How it works:
On-chain data aggregation: Spark Data Hub collects data from Spark Savings, SparkLend, and SLL, including transaction volume, yield rates, and stablecoin balances (USDS, sUSDS, USDC).
Data display: Data is shown through a user-friendly interface on the website, allowing users to explore metrics like total allocated assets or pre-farmed SPK details.
Airdrop support: Provides details about airdrops like Ignition and Overdrive, including distributed SPK amounts and participation conditions (e.g., holding USDS, sUSDS, or interacting with SparkLend).
Roadmap
Spark’s 10-year SPK token distribution roadmap includes:
🔥2025: Launch of Ignition and Overdrive airdrops, multi-chain expansion
🔥Long-term: Strengthen decentralized governance, develop more DeFi products
🔥Release schedule: 1.625 billion SPK/year, gradually decreasing to 203 million SPK/year from year 7 onward.
Binance HODLer Airdrops – A simple way to earn free tokens
