Spark Protocol has published a series of proposed changes slated for an upcoming executive spell on Ethereum, covering treasury operations, token buybacks, reserve management, and liquidity layer adjustments.
—
The February 26, 2026 proposal outlines actions spanning the Spark Foundation Grant for March, the SPK Buybacks Transfer for February 2026, a SparkLend reserves claim, and increased rate limits for USDT on the Spark Liquidity Layer.
The proposed spell bundles multiple governance actions into a single onchain execution — a standard practice within the Sky (formerly MakerDAO) ecosystem that allows stakeholders to review and vote on a package of protocol changes simultaneously.
Each item in the proposal addresses a distinct operational need within Spark's growing infrastructure on Ethereum.

Spark Foundation Grant and SPK Buybacks
The first item in the proposal is the Spark Foundation Grant for March, an executive-level treasury disbursement intended to fund ongoing foundation operations.
These periodic grants have become a recurring feature of Spark's governance cadence, providing the foundation with the capital needed to support development, ecosystem growth, and operational overhead on a monthly basis.
Alongside the grant, the spell includes the SPK Buybacks Transfer for February 2026. This action transfers funds earmarked for purchasing SPK tokens on the open market — a mechanism designed to create consistent buy-side demand for the protocol's native token.
Buyback programs in DeFi serve a similar function to share repurchases in traditional finance: they reduce circulating supply and signal the protocol's confidence in its own token economics.
The combination of a forward-looking March grant with a February buybacks settlement reflects Spark's approach to treasury management — maintaining operational funding while simultaneously executing on its tokenomics strategy.
Both actions require executive-level approval through the governance process before on-chain execution.
SparkLend Reserve Claims
The proposal also includes a Claim Reserves execution for SparkLend, Spark Protocol's lending and borrowing platform. Reserve claims allow the protocol to collect accumulated fees and surplus capital from SparkLend's lending pools, directing those funds back into the treasury for reallocation.
SparkLend generates revenue through interest rate spreads between borrowers and lenders, with a portion of that revenue accruing to protocol reserves. Periodic claims ensure that these reserves are actively managed rather than sitting idle within the lending contracts. The claimed funds can then be deployed toward buybacks, grants, liquidity provisioning, or other governance-approved uses.
This reserve management cycle — accumulate, claim, redeploy — is a core component of how Spark maintains its financial sustainability. It also provides transparency into the protocol's revenue generation, as each claim is visible on-chain and subject to governance oversight.

USDT Rate Limit Increase on Liquidity Layer
Perhaps the most operationally significant change in the proposal is the increase in the rate limit for SparkLend USDT on the Spark Liquidity Layer. Rate limits in this context govern how quickly USDT can flow into or out of SparkLend through the Liquidity Layer — effectively controlling the pace at which liquidity can be added or withdrawn.
Raising the USDT rate limit suggests growing demand for Tether-denominated lending and borrowing on SparkLend. As USDT remains the largest stablecoin by market capitalization and trading volume, expanding its throughput capacity on the Liquidity Layer positions Spark to capture a larger share of stablecoin lending activity on Ethereum.
The Spark Liquidity Layer serves as the infrastructure connecting various liquidity sources to SparkLend's lending markets, and rate limit adjustments are a key lever for managing risk while scaling capacity.
Rate limits function as a risk management tool: they prevent sudden, large-scale liquidity movements that could destabilize lending pools or create exploitable conditions. By incrementally raising these limits, Spark governance can scale USDT capacity in a controlled manner, balancing growth with protocol safety.
The proposal also references additional Spark Liquidity Layer changes, though the full details are contained within the governance forum post.
Broader Context Within the Sky Ecosystem
Spark Protocol operates as a key sub-protocol within the broader Sky ecosystem (the rebranded MakerDAO). Since its launch, Spark has carved out a significant role in DeFi lending, particularly for DAI and USDS-denominated markets.
The protocol's governance structure mirrors Sky's — proposals are posted to the forum, discussed by delegates and community members, and ultimately executed through on-chain spells. The bundling of treasury, buyback, and infrastructure changes into a single spell is characteristic of how the Sky ecosystem manages governance overhead.

Rather than conducting separate votes for each action, batching reduces voter fatigue and streamlines execution. However, it also means that stakeholders must evaluate the full package, as individual items cannot typically be separated during the voting process.
Spark's continued investment in its Liquidity Layer and lending infrastructure comes at a time when competition among DeFi lending protocols remains intense.
Aave, Morpho, and Euler are all vying for market share, making operational efficiency and capital deployment speed critical differentiators. The USDT rate limit increase, in particular, signals Spark's intent to remain competitive in stablecoin lending markets.
What to Watch
The proposed changes are currently in the forum discussion phase and will need to pass through the standard governance voting process before execution. Key items to monitor include:
Governance vote timing and outcome — Whether the bundled spell passes and when execution occurs on-chain.
SPK buyback execution details — The size and timing of the February buybacks transfer and its impact on SPK token markets.
USDT utilization on SparkLend — Whether the increased rate limit leads to measurable growth in USDT lending and borrowing activity.
Reserve claim amounts — The total value of claimed reserves, which provides a proxy for SparkLend's recent revenue performance.
Stakeholders and SPK holders can follow the discussion and vote progression on the Sky governance forum. The spell's execution will be publicly verifiable on Ethereum once the governance process concludes.
