Sky Protocol's annualized revenue has climbed to approximately $419 million, with demand for the USDS stablecoin driving the protocol's DeFi income, according to protocol-level data tracked by CryptoRank.

The figure consolidates gross fees and seigniorage captured across the Sky ecosystem, the framework that absorbed MakerDAO's operations under a rebrand that repositioned Dai as USDS and introduced a savings-rate mechanism to distribute protocol earnings directly to holders. CryptoRank's annualized methodology tracks on-chain revenue streams without adjusting for token emissions or liquidity incentives, a distinction that compresses the apparent revenue of competing protocols that lean on subsidies to inflate their fee totals.

How Sky generates revenue

USDS operates as an overcollateralized stablecoin, with its supply backed by crypto-native collateral posted to Sky vaults and by tokenized real-world assets held through the protocol's RWA infrastructure, including exposures to short-dated US Treasury bills. Borrowers post collateral and mint USDS against it, paying a stability fee that constitutes the protocol's primary revenue stream.

A portion of that stability-fee income is then redistributed to USDS holders who opt into the Sky Savings Rate, recycling protocol revenue back into depositor yields. The wider the spread between the rate charged to borrowers and the rate paid to savers, the larger the residual income retained by the protocol itself. This structure converts Sky from a single-product stablecoin issuer into a yield-distribution network whose economics scale with stablecoin float rather than with trading or derivatives volume.

Operational positioning

The near-$419 million annualized figure would rank Sky among the higher-grossing decentralized networks on a fee-capture basis, alongside the largest perpetual DEXs and lending markets measured by annual gross revenue. Sky's model anchors earnings to stablecoin float rather than to speculative turnover, differentiating the protocol from exchange-style or perpetual-DEX competitors whose revenue correlates with derivatives volume.

That positioning insulates Sky's income stream from cyclical swings in DEX and lending markets, but concentrates exposure to USDS peg stability and to the regulatory classification of yield-bearing stablecoins across major jurisdictions. As USDS supply expands, the protocol's revenue line becomes increasingly tethered to the willingness of regulated venues and institutional counterparties to accept a yield-bearing stablecoin as a settlement or treasury instrument.

Regulatory backdrop

The European Union's MiCA framework restricts yield-bearing features for regulated e-money tokens, complicating USDS distribution to EU-based customers and shaping how Sky structures retail-facing offerings in the region. In the United States, pending federal stablecoin legislation is working through whether pass-through savings distributions constitute securities offerings. Either regulatory resolution could materially alter the operating economics of yield-bearing stablecoins including USDS and reshape Sky's cost of acquiring new depositors and treasury counterparties.

Forward outlook

The pace of the revenue run-rate will continue to track USDS supply expansion, which depends in turn on the relative competitiveness of the Sky Savings Rate against emerging yield-bearing stablecoins and on the regulatory clarity surrounding yield distribution. CryptoRank's metric offers a benchmark for tracking the migration of stablecoin-driven income from centralized issuers into decentralized infrastructure as the regulatory picture develops.
