Sky Protocol

Eight years of continuous operation and a stablecoin that has held, now steering into off-chain credit with less clarity than it deserves.

The short answer

Maker built the credit mechanism the rest of DeFi copied, and DAI has held its peg through every crisis since 2017. The concern is direction: a growing share of backing is off-chain credit whose counterparties users cannot inspect, wrapped in a rebrand that reduced rather than improved governance legibility.

What we liked

  • DAI has held its peg through every crisis since 2017
  • Oracle security module and emergency shutdown are genuine safeguards
  • Enormous, genuinely used liquidity

Where it falls short

  • Real-world asset exposure introduces opaque counterparty risk
  • The Sky rebrand and endgame restructuring have made governance harder to follow

Sky, formerly MakerDAO, is the longest-running credit system in crypto. Its stablecoin has survived Black Thursday, the collapse of Terra, the 2022 lending contagion and the 2023 banking scare, which is a stronger track record than any other decentralised stablecoin can claim.

What the protocol actually does now

Users lock collateral to mint DAI or USDS and pay a stability fee. Increasingly, however, the system's income comes not from crypto-collateralised borrowing but from real-world asset exposure — treasuries, private credit and structured arrangements held through legal entities and off-chain counterparties. That is where the savings rate paid to holders originates.

The transparency question

On-chain collateral can be verified by anyone. Off-chain credit cannot: users are trusting the governance process, the legal structures and the counterparties selected. Neither is inherently wrong, and the shift changes what kind of instrument DAI is. Anyone describing it as fully verifiable on-chain money should check the current collateral composition.

Governance legibility

The endgame restructuring introduced new tokens, subDAOs and a more complex governance architecture. Following what the protocol holds and who decides it has become harder, not easier, which is a genuine cost for a system whose main claim is transparency.

Who should care

DAI and USDS holders, and anyone assessing whether decentralised stablecoins remain decentralised as they scale.

FAQ

What backs DAI now?
A mixture of crypto collateral and a significant share of real-world assets including treasury exposure and private credit, held through off-chain counterparties.
Has DAI ever lost its peg?
It has traded above and below par during crises, most notably in March 2020 and during the 2023 USDC banking scare, and has returned to peg each time.
What changed with the Sky rebrand?
New tokens USDS and SKY alongside DAI and MKR, plus a restructured governance model with subDAOs, which has made following protocol decisions more complex.
Is Sky still decentralised?
Governance is on-chain, but a large share of backing sits with off-chain counterparties selected through that governance, which is a different kind of trust than verifiable collateral.
