Maker (MKR)

Sky, known until August 2024 as MakerDAO, is a decentralized finance (DeFi) protocol built on the Ethereum blockchain that issues USDS (formerly DAI), a decentralized, dollar-pegged stablecoin, and is governed by holders of SKY, the protocol's native governance token (formerly MKR). Sky is among the oldest continuously operating major protocols in decentralized finance, having launched its original DAI stablecoin in 2017, and has since developed into one of the largest DeFi protocols by both total value locked and reported annualized revenue, with an increasing share of that revenue derived from real-world assets such as tokenized U.S. Treasury securities rather than from purely crypto-native lending activity.¹²

The rebrand from MakerDAO to Sky was announced by founder Rune Christensen and launched on August 27, 2024, as the first concrete step in a multi-year restructuring effort known as the "Endgame Plan," under which the original MakerDAO protocol has been progressively reorganized into a modular network of semi-independent sub-projects, initially called SubDAOs and subsequently rebranded as "Sky Stars."³⁴⁵ As part of the rebrand, holders of the legacy MKR governance token were offered the ability to convert their tokens to SKY at a fixed ratio of 1 MKR to 24,000 SKY, while DAI holders were offered a parallel, optional 1:1 upgrade path to USDS.⁶⁷⁴ Both legacy tokens, MKR and DAI, have continued to exist and remain functional alongside their newer counterparts, with users free to choose between them, though only SKY confers governance rights, staking eligibility, and access to certain reward programs within the reorganized protocol.¹⁵

The rebrand proved controversial within Sky's own community, drawing criticism over branding confusion, a sharp decline in MKR's price following the announcement, and a comparatively slow initial pace of token migration, prompting the project's leadership to hold a formal community vote in late 2024 on whether to reverse the rebranding entirely; the Sky name was ultimately retained.⁷⁸ Notwithstanding this rocky initial reception, Sky's underlying business metrics grew substantially over the following two years: by early 2026, the protocol's stablecoins collectively exceeded $12 billion in combined circulating value, its total value locked had reached approximately $7.5 billion, placing it among the four largest DeFi protocols by that measure, and its reported annualized revenue had grown to approximately $435 million, with roughly 60% to 70% of that revenue derived from off-chain and real-world-asset sources such as tokenized Treasury funds and centralized-exchange stablecoin reward programs.¹² A major technical milestone in this ongoing transition occurred on April 7, 2026, when Binance, the world's largest cryptocurrency exchange by trading volume, executed an automatic, exchange-wide conversion of all customer DAI balances to USDS, an event commentators described as the largest single stablecoin conversion in the history of the cryptocurrency industry.³

History

Origins as MakerDAO

MakerDAO was founded by Rune Christensen, a Danish entrepreneur, with the protocol's DAI stablecoin launching in December 2017 as one of the first decentralized, overcollateralized stablecoins in the cryptocurrency industry. Unlike centralized, fiat-backed stablecoins such as Tether's USDT or Circle's USDC, which are backed by reserves held and managed by a single company capable of freezing or restricting individual users' holdings, DAI was designed to maintain its dollar peg through a decentralized system of crypto-collateralized "Vaults," in which users could lock collateral assets, such as ether, and mint DAI against that collateral, with the entire process governed by holders of MKR, the protocol's original governance token, who set risk parameters, collateral types, and stability fees through on-chain votes.² Over the following several years, DAI became one of the most widely used and integrated stablecoins in decentralized finance, serving as a default unit of account for major protocols including Aave, Compound, and Curve, and functioning as one of the clearest early demonstrations that a stablecoin could operate without reliance on a centralized, fiat-holding issuer.³

Endgame Plan

In 2022, Christensen proposed a long-term restructuring initiative for MakerDAO known as the "Endgame Plan," intended to give the protocol additional room to scale by reorganizing its previously unified structure into a network of smaller, more focused, semi-independent units, initially referred to as SubDAOs, each responsible for a specific product line or business focus while remaining connected to, and drawing security and liquidity from, the broader Maker ecosystem.²⁵ The first such SubDAO, Spark, focused on decentralized lending through a product called SparkLend, launched ahead of a planned token airdrop and went on to become one of the more prominent components of the broader ecosystem, eventually managing several billion dollars in total value locked across its lending and liquidity products.¹²

Rebrand to Sky

The first major public-facing element of the Endgame Plan was the rebranding of MakerDAO itself to Sky, announced by Christensen and launched on August 27, 2024. The rebrand introduced two new tokens intended to eventually supersede MakerDAO's original assets: USDS, described as an upgraded version of DAI offering integrated access to a variable-rate yield mechanism called the Sky Savings Rate without requiring users to separately redeploy their capital into a distinct savings contract, and SKY, a redenominated successor to the MKR governance token, converted at a fixed ratio of 1 MKR to 24,000 SKY, a redenomination explicitly intended to lower the per-unit price of the governance token and thereby broaden practical participation in the protocol's governance among smaller individual holders.⁷⁴⁵ The rebrand also renamed the protocol's SubDAOs as "Sky Stars," and renamed the project's overarching governance rulebook "Sky Atlas."¹⁹ Both DAI and MKR continued to exist as functioning tokens following the rebrand, convertible to their newer counterparts through a dedicated smart contract but not required to be converted, and Christensen stated at the time that both the legacy and new tokens were expected to remain unchanged and available indefinitely, absent a future governance decision to the contrary.⁴

Community backlash and reversal vote

The Sky rebrand drew substantial criticism from within the project's own community in the weeks following its announcement, with many longtime MKR and DAI holders expressing confusion over the new branding and a preference for retaining the original, better-established MakerDAO and DAI names, given the brand recognition and years of accumulated trust those names had built within the broader DeFi ecosystem.⁷ Reflecting this reception, MakerDAO's governance process scheduled a community call for October 25, 2024, to discuss the possibility of reversing the rebrand, followed by a formal governance vote on the matter set for November 4, 2024.⁷ Ultimately, the Sky branding was retained following this process, though the episode was widely covered as an example of the practical difficulty large, established DeFi protocols can face in fundamentally altering their public identity even when the underlying technical and strategic rationale for doing so is considered sound by the project's own leadership.⁷⁸ Christensen was later reported to have described the rebrand's execution candidly, characterizing its estimated $5 million cost as reflecting what he termed a "typical DeFi mistake," and noting that MKR's price fell by roughly 50% from its pre-rebrand levels in the aftermath of the transition, with SKY itself debuting at a market capitalization below $60 million — a figure some commentators characterized at the time as disappointing relative to the scale of the underlying protocol.⁸

Adoption trends and slow initial migration

In the months immediately following the rebrand's launch, migration from the legacy MKR token to SKY proceeded comparatively slowly; one industry report from around the time of major exchange-level migration deadlines in September and October 2024 estimated that only approximately 10.7% of MKR holders had converted their tokens to SKY, a figure some commentators cited as evidence of low initial adoption, while others suggested it instead reflected substantial pent-up conversion demand still to be realized as additional exchanges and platforms completed their own migration processes.¹⁰ Centralized exchanges played a significant role in coordinating this transition: Binance, for example, set a deadline of mid-September 2024 for delisting existing MKR trading pairs ahead of the official SKY trading-pair launch on September 17, 2025, while other major exchanges, including Bitfinex, established their own comparable migration timelines and post-deadline conversion fee structures intended to encourage users to complete the token swap in an orderly fashion.⁶⁸

Spark, additional Sky Stars, and NewChain

Following Spark's launch as the first Sky Star, its associated SPK governance token launched via a 300-million-token airdrop on June 17, 2025. Spark subsequently grew to manage several billion dollars in total value locked across its SparkLend lending product and an associated Spark Liquidity Layer, deploying billions of dollars in capital across decentralized finance, centralized finance, and real-world-asset investment strategies.² Additional Sky Stars, including a project called Keel, were subsequently launched as part of the broader Endgame restructuring, each maintaining its own dedicated governance token and product focus while remaining connected to the broader Sky ecosystem's shared liquidity and security infrastructure.⁵ Later phases of the Endgame Plan have envisioned the eventual launch of NewChain, a dedicated, Maker-branded layer-1 blockchain intended specifically to host the technical infrastructure and governance logic underlying the broader network of Sky Stars, with Christensen having suggested in an earlier 2023 forum post that the new chain could be built by forking the Solana blockchain's codebase; as of mid-2026, no concrete technical work on NewChain had shipped, with its development timeline understood to remain tied to later, more distant phases of the Endgame roadmap.⁵

The April 2026 DAI-to-USDS exchange migration

On April 7, 2026, Binance executed a large-scale, automatic conversion of customer DAI balances to USDS across its platform, delisting existing DAI trading pairs and converting all customer holdings to the newer token at a fixed 1:1 ratio.³ Commentators described the event as the culmination of Sky's broader, multi-year transition away from its original MakerDAO branding, noting that the migration touched approximately $7.9 billion in outstanding stablecoin liabilities and required numerous other major DeFi protocols, including Aave, Compound, and Curve, to individually determine how they would treat the shift between the two tokens within their own platforms going forward.³ Reports at the time noted that USDS's circulating market capitalization had grown to approximately $7.9 billion to $8.7 billion, with a reported 26.7% month-over-month increase in circulation shortly before the Binance migration, formally overtaking DAI's own circulating supply, though DAI itself continued to circulate at a still-substantial scale — reported at approximately $4.66 billion to $5.3 billion depending on the specific date referenced — reflecting its continued use across DeFi pools, lending markets, and blockchain networks that had not yet integrated USDS as of that time.³¹⁰²

Technology

USDS and the Sky Savings Rate

USDS functions as an upgraded, largely interchangeable counterpart to Sky's original DAI stablecoin, convertible at a fixed 1:1 ratio through a dedicated smart contract known as the SkyMoneyConverter, which operates as a lock-mint and burn-mint pair enabling conversion in either direction with no fee and, because the mechanism functions as a smart-contract-based escrow rather than a market, no slippage.¹⁰ USDS is designed to offer integrated access to the Sky Savings Rate (SSR), a variable-rate yield mechanism — reported at approximately 3.75% annual percentage yield during parts of 2026 — that allows holders to earn a return on their USDS holdings by converting a portion of their balance into sUSDS, an interest-accruing wrapped version of the token, without needing to separately deploy their capital into a distinct external savings contract, in contrast to DAI, which requires users to actively lock their tokens into a comparable, separate contract in order to access equivalent yield.¹⁰⁵ Unlike DAI, USDS was also designed with a freezing capability, allowing centralized intervention in specific, defined circumstances such as addressing transfer errors or responding to theft, a feature its designers have described as motivated in part by an effort to more effectively navigate the compliance expectations of institutional and regulatory counterparties.⁶

SKY governance token and staking

SKY replaced MKR as Sky's sole governance token, with holders responsible for voting on protocol upgrades, fee adjustments, collateral and asset-onboarding policies, and broader risk-management decisions affecting the protocol.¹ The redenomination of MKR into SKY at a ratio of 24,000 SKY per MKR was intended specifically to lower the token's per-unit price, thereby making meaningful governance participation more practically accessible to individual holders who might otherwise be priced out of holding an economically significant stake in a token trading at a much higher per-unit value.¹⁴ SKY holders can additionally stake their tokens to earn Sky Token Rewards, distributed at a rate that was set, at the program's 2024 launch, at 600 million SKY annually across participating USDS holders, subject to ongoing adjustment through governance, with such reward programs restricted in certain jurisdictions, including the United States and United Kingdom, and unavailable to users accessing the platform through a VPN.⁴ A related mechanism known as Sealed Activation allows users to lock their SKY or legacy MKR tokens for a period in exchange for higher reward rates, while retaining the ability to delegate their voting power during the lockup period, subject to an exit fee if the tokens are unsealed and withdrawn before the committed period concludes.⁹

Sky Stars

Sky Stars, the rebranded successor to Maker's original SubDAO concept, are semi-independent projects operating within the broader Sky ecosystem, each maintaining its own dedicated governance token, treasury, and product focus while drawing on the security, liquidity, and broader institutional infrastructure of the parent Sky Protocol.⁵⁹ Spark, the first and most prominent Sky Star, focuses on decentralized lending and liquidity-deployment products, including SparkLend and the Spark Liquidity Layer, and had grown, by the mid-2020s, to manage several billion dollars in total value locked, deploying capital across a range of decentralized-finance, centralized-finance, and real-world-asset investment strategies.¹²⁹

Real-world asset integration

A defining feature of Sky's business evolution since its 2024 rebrand has been a substantial pivot toward generating protocol revenue from real-world assets rather than relying predominantly on stability fees charged against crypto-native collateral, as had been the case for much of MakerDAO's earlier history. Through Spark and an associated capital-allocation initiative known as Obex, which reportedly carried a $2.5 billion allocation mandate, Sky deployed billions of dollars of its USDS reserves into instruments including tokenized U.S. Treasury funds and corporate bond products.³ This shift proved consequential for the protocol's revenue stability: whereas MakerDAO's original, crypto-collateral-driven revenue model had generated income closely tied to the volatility of crypto-asset prices — rising during periods of high liquidation activity and falling during quieter market conditions — Sky's growing real-world-asset revenue base meant that a substantial share of its income continued to accrue from Treasury-yield and bond-coupon payments largely independent of cryptocurrency-market sentiment, a dynamic commentators specifically highlighted during a sharp Bitcoin price decline in early 2026, when Sky's reported revenue reportedly remained comparatively stable even as broader crypto markets fell substantially.³

Business performance

By the first quarter of 2026, Sky's total value locked had grown to approximately $7.5 billion, making it, by that measure, the fourth-largest decentralized finance protocol.³ The protocol's combined stablecoin supply, spanning both USDS and the continuing legacy DAI token, reached a combined total exceeding $12 billion, with real-world-asset-derived income accounting for more than 60% of Sky's total revenue by early 2026 — described by commentators as a complete inversion of the protocol's original, crypto-native economic model.³ Sky's reported annualized revenue reached approximately $435 million as of December 2025, with roughly 70% of that figure derived from off-chain sources, including centralized-exchange stablecoin-related reward programs and tokenized Treasury-fund income.² Commentators reviewing the protocol's decade-long operating history in 2026 noted that, unlike many other DeFi projects that had launched and subsequently failed or been abandoned, Sky's underlying Maker Protocol infrastructure had operated continuously since 2017, had survived the broader 2022 cryptocurrency-market downturn without a protocol-wide loss of user funds, and had continued to distribute a share of its revenue back to token holders through mechanisms including MKR and SKY buybacks and periodic Sky Star token airdrops.²

Criticism

Sky's 2024 rebrand from MakerDAO drew sustained criticism on several fronts. The most immediate criticism centered on branding and communication: many longtime MakerDAO and DAI users expressed confusion regarding the new Sky, USDS, and SKY naming conventions, and a preference for retaining the original, more widely recognized MakerDAO brand, a level of pushback substantial enough to prompt the project's own governance process to hold a formal vote on reversing the rebrand entirely within months of its launch.⁷⁸ Rune Christensen's own subsequent, relatively candid public characterization of the rebrand's roughly $5 million cost as a "typical DeFi mistake," together with MKR's approximately 50% price decline in the rebrand's immediate aftermath and SKY's comparatively modest sub-$60-million market capitalization at launch, were cited by commentators as further evidence that the rebrand's initial execution and market reception had fallen meaningfully short of the project's own expectations, even as the underlying protocol's business metrics continued to grow substantially over the following two years.⁸

The introduction of a freezing function within USDS — a capability absent from the original, more strictly decentralized DAI token — has also drawn scrutiny from some observers within the broader DeFi community, who have noted the tension between this feature and the historical positioning of DAI as a stablecoin specifically designed to operate without any centralized party capable of freezing or restricting individual users' holdings, a distinguishing characteristic that had differentiated DAI from centralized stablecoins such as Tether's USDT and Circle's USDC. Proponents of the change have argued that the freezing capability is a narrowly scoped, governance-controlled tool intended to address specific circumstances such as transfer errors or theft, and reflects Sky's broader strategic effort to make its products more compatible with the compliance expectations of institutional counterparties and regulators, particularly as the protocol has expanded its real-world-asset investment activities, rather than representing a wholesale abandonment of the protocol's original decentralization principles.⁶²

Separately, Sky's growing reliance on real-world-asset revenue and off-chain, centralized financial instruments, such as tokenized Treasury funds and centralized-exchange stablecoin reward programs, has prompted broader debate within the DeFi community regarding the appropriate balance between a protocol's stated decentralization ideals and the practical financial benefits of deeper integration with traditional financial infrastructure, with commentators generally acknowledging that this shift has provided Sky with a more stable and diversified revenue base while also tying an increasing share of the protocol's underlying economics to conventional, centrally issued financial instruments rather than purely crypto-native collateral and activity.³²
