What is Spark Protocol?

Spark Protocol is a new type of DeFi infrastructure built on Ethereum and its rollups, with the mission to address the common issues in the past DeFi market: the dispersion of capital liquidity, unstable yields, and a large amount of idle capital in stablecoins that cannot be effectively utilized. Spark is not a single application, but is designed as the core liquidity and yield layer of on-chain finance, redefining the flow of capital within the DeFi ecosystem.

The main product of Spark Protocol

The Spark Protocol architecture includes three core product lines:

1. SparkLend: Decentralized Currency Market
   This is a non-custodial lending market that supports users in depositing stablecoins and blue-chip assets to earn interest income. Users can also borrow on the condition of providing over-collateralization. SparkLend is designed to be highly flexible, supporting high-efficiency lending (E-Mode), asset isolation mode (Isolation Mode), and siloed borrowing, enhancing risk control capabilities and market scalability.

2. Spark Savings: Stablecoin Yield Aggregator
   Through Spark, users holding stablecoins such as USDS and DAI can earn on-chain stable returns. These returns come from Spark deploying stablecoin liquidity from the Sky ecosystem into DeFi, CeFi, or RWA (real-world asset) markets, thereby earning risk-adjusted returns.

3. Spark Liquidity Layer: Liquidity Base Layer
   The liquidity layer of Spark directly provides stable liquidity to other DeFi protocols, which not only strengthens the stability of the DeFi ecosystem but also allows protocol participants to obtain a more stable source of profit from these markets.

The tokenomics of Spark Protocol

The initial total supply of SPK is 10 billion tokens, created for protocol operation, governance, and user incentives. The distribution structure is as follows:

• Sky Farming User Incentives (65%): 6,500,000,000 SPK will be distributed to ecosystem users by the Sky protocol over the next 10 years, rewarding users for participating in various Spark applications and accessing liquidity.
• Ecosystem Development (23%): 2,300,000,000 SPK will be used to support the Spark ecosystem, including developer grants, protocol integration, marketing promotion, and cross-chain expansion. Of this, 17% will be unlocked immediately at TGE (Token Generation Event), and the remaining 6% will be unlocked one year later.
• Team and Advisors (12%): 1,200,000,000 SPK allocated to the founding team and early contributors of the protocol. A one-year cliff (lock-up period) is applied, followed by a linear release of the remaining amount over three years.

The Sky protocol has the ability to mint additional SPK in extreme circumstances (for example, for the settlement of bad debts), and this mechanism is governed and controlled by the DAO's strict governance and transparency mechanisms.

SPK Token Functions and Roles

SPK is the governance and staking token of the Spark Protocol, serving the following three main functions:

• Governance Participation: SPK holders can participate in the governance decisions of Spark DAO, influencing protocol parameters, asset additions, and market strategies through Snapshot voting.
• Staking Security: Users can stake SPK to participate in the protocol's security and validation mechanism. Future submodules in the Spark ecosystem may also require staking SPK to ensure proper operation.
• Incentive Distribution: Users who stake SPK can earn Spark Points, which can be exchanged for rewards and airdrop qualifications in Spark or its partner protocols, enhancing user engagement.

Spark is currently deployed on multiple chains including Ethereum, Arbitrum, Base, Optimism, Unichain, and Gnosis Chain, managing over $3.5 billion in stablecoin liquidity and generating more than $170 million in annualized protocol revenue, making it one of the most revenue-efficient protocols in the DeFi space.

Summary

Spark is not just an alternative DeFi lending protocol, but rather the underlying structure of the on-chain yield market, connecting multi-chain, multi-asset, and multi-application financial needs with stable, modular, and highly elastic design. It does not compete with other protocols, but empowers the entire DeFi ecosystem by providing core funding and yield services. As SPK governance further decentralizes, cross-chain deployment deepens, and more Spark applications are released, its role will evolve from a DeFi patch to the engine of the entire on-chain yield market.
