Sky (SKY)

What Sky is

Sky is a decentralized finance protocol that issues the USDS stablecoin and routes the capital behind it to independent allocators. SKY is its governance token, an erc 20 on Ethereum. Sky Ecosystem describes the protocol as "a global and transparent liquidity infrastructure through which independent capital allocators access USDS liquidity under governance-set risk parameters" (source: skyeco.com, read September 2026).

Sky is the successor to MakerDAO. Sky's own materials describe the protocol as "heir to MakerDAO, which has been deploying stablecoin infrastructure since 2017" and state that in 2025 S&P Global issued it "the first credit rating any DeFi protocol has ever had" (source: sky.money, sUSDS page, September 2026).

Two front ends matter for reading anything about Sky correctly, because neither controls the protocol. Sky.money is operated by Skybase International, "a non-custodial interface" whose disclosure says it "does not control Sky Protocol smart contracts or ecosystem governance." Skyeco.com is managed by the Sky Frontier Foundation, "an independent entity" that likewise "does not have authority over Sky Protocol, its smart contracts, or governance decisions." Parameters are set by SKY holders voting onchain.

How it works

USDS is the protocol's stablecoin. Supply USDS to the savings module and you receive sUSDS, which accrues the Sky Savings Rate continuously, so a fixed sUSDS balance becomes redeemable for more USDS over time. Sky describes the Sky Savings Rate as "a variable protocol rate funded from aggregate Sky protocol surplus," and is explicit that "sUSDS is not exposure to any specific Agent, borrower, collateral pool, or asset strategy." As of September 2026 sky.money published the rate at 3.52% APY with total sUSDS supply of 4.71 billion, and said there are no lockups, no maturity dates and no entry or exit fees through its interface.

The surplus that funds that rate comes from the Sky Agent Network. Agents are independent capital allocators that draw USDS liquidity under limits set by governance, and the protocol's architecture "enforces those parameters, manages liquidity flows, and automates settlement" (source: skyeco.com, September 2026). The Sky governance forum lists several named Prime Agents, including Spark Prime and Grove Prime. Spark's own documentation points readers to Sky's collateral backing dashboard for the assets behind USDS, and describes its savings vaults as "backed by USDS" (source: docs.spark.fi, September 2026).

SKY itself is put to work through the Staking Engine, which Sky describes as "a flexible, all-in-one smart contract that lets you put your SKY to work without a lockup period." A staked position does three jobs at once. It accrues staking rewards, it carries voting power that can be delegated without affecting those rewards, and it can be used as collateral to borrow USDS. Sky states that borrowing does not interrupt rewards: staked SKY "continues to accrue 100% of its staking rewards even if you have an active USDS loan." Rewards are not automatically restaked and must be claimed manually. As of September 2026 sky.money published a SKY staking rate of 4.22% APY and a SKY borrowing rate of 6.52% APR, both set by governance and both variable.

Where the staking rewards come from is the part worth understanding, because it is not token emission. Sky's published explanation is that rewards "are funded from aggregate Sky protocol surplus. Stability fees contribute to that surplus, and Agents activity may contribute as well. The surplus is programmatically used to buy SKY on the open market, which is then distributed to participants in the Staking Engine."

Two other products sit alongside sUSDS at the sky.money interface. stUSDS yield "is generated dynamically through SKY-backed lending within Sky Protocol and is dependent on the Utilization Rate," published at 5.38% APY in September 2026. Vaults are curated by Sky.money and "run on Morpho vault contracts," published at up to 5.17% APY, with Sky.money selecting which lending markets each vault may use and setting exposure limits while not holding vault assets.

Supply and tokenomics

Sky publishes rates and balances in detail and is comparatively reticent about SKY's supply. Its own FAQ says only that "SKY has a capped total supply; current figures are published in the protocol documentation," and adds that "buybacks by the Smart Burn Engine reduce circulating supply as a mechanical effect." No numeric cap is stated on the pages read for this entry, so none is given here. Read the figure from the data on this page or from a current Sky disclosure.

The economic loop is a buyback and burn in one direction and a buy-and-distribute in the other. Protocol surplus buys SKY on the open market to pay stakers, and the Smart Burn Engine's buybacks reduce circulating supply. Neither is an emission schedule, so the reward rate depends on protocol revenue rather than on new issuance.

History

Sky is the rebranded continuation of MakerDAO, the protocol that launched the DAI stablecoin and popularized over collateralization as a way to issue a dollar-denominated asset without a bank. Sky's materials date the lineage to 2017 and claim continuous operation "through every market cycle" with "no exploits."

The structural change under the Sky name is the split between the protocol and the parties that use it. Rather than one governance body approving every collateral type directly, Sky exposes USDS liquidity to a network of Agents that compete to allocate it, with the risk limits written into governance parameters and enforced by contract. The Sky Savings Rate is the visible consequence of that design: because it is funded from aggregate surplus, a saver's rate is not tied to the fortunes of any single allocator.

Reporting moved with it. Financial statements, collateral backing, Prime Agent capital and liquidity views are published as a read-only analytics site by BA Labs, which states plainly that it "is independent of official protocol documentation" (source: financial.skyeco.com, September 2026).

Risks and what to watch

Governance concentration is the first thing to watch. The rate you earn, the rate you pay, the risk limits on Agents and the buyback program are all decisions made by token holders. That places weight on how widely SKY voting power is distributed and how much of it is delegated to a small number of addresses.

Borrowing against staked SKY carries liquidation risk, and Sky says so directly: "if the price of SKY drops significantly, your position could face liquidation. Always monitor your Health Factor." Because the loan is funded by the stUSDS risk pool, stress in one part of the system is connected to the other.

Agent risk is structural rather than hypothetical. USDS backing is deployed by independent allocators, and the collateral behind it is what a holder ultimately relies on. Sky publishes that backing at its collateral dashboard; a reader who cares about the quality of the reserves should look there rather than at the headline rate.

Smart contract risk applies as it does to any onchain system, and the Morpho-based vaults and the Pendle-based fixed-yield product add integrations Sky governance does not control. The interfaces are also not the protocol: Skybase International and the Sky Frontier Foundation both disclaim authority over the contracts.

Frequently asked questions

What is the Sky Savings Rate?

A variable protocol rate paid on sUSDS, funded from Sky's aggregate protocol surplus rather than from token emissions or from one lending market's borrowing demand. Every change is proposed and voted onchain before it takes effect. It was published at 3.52% APY in September 2026.

What does staking SKY do?

Through the Staking Engine, a staked SKY position accrues rewards, carries voting power that can be delegated, and can be used as collateral to borrow USDS. Sky states there is no lockup period and that rewards must be claimed manually.

Where do SKY staking rewards come from?

From protocol surplus, not from new issuance. Sky's published description is that the surplus "is programmatically used to buy SKY on the open market, which is then distributed to participants in the Staking Engine."
