ECB Finds Top 100 Holders Control Over 80% Of Aave, MakerDAO, Ampleforth, Uniswap Supply

The ECB's March 26 working paper reveals a sharp deviation from the ideal of fully distributed governance in DeFi: power is heavily concentrated in a small set of addresses across four major protocols.

It finds the top 100 holders control more than 80% of the supply in Aave, MakerDAO, Ampleforth, and Uniswap.

Binance is identified as the largest centralized-exchange holder across the four protocols, illustrating how regulated market actors can influence on-chain decisions.

The study also shows that most voting power is exercised by delegates who wield authority on behalf of smaller holders, concentrating influence in a handful of voters.

The authors stress that the paper reflects researchers' views and not ECB policy, and caution that public data do not reliably reveal who ultimately controls protocol-held funds or how exchanges vote.

The ECB paper argues that identifiable control points—developers, treasuries, or exchange listings—could serve as practical anchors for regulation, given MiCA's framework.

MiCA currently excludes fully decentralized services, creating a policy tension between decentralization rhetoric and governance realities.

The study underscores that real authority often rests with delegates who marshal votes from smaller holders, which can concentrate influence in a handful of actors.

There are data gaps, noting that it is not always possible to tell whether protocol-linked holdings belong to founders, treasuries, or third parties, and whether exchange wallets vote their own positions or customers'.

The authors caution that the anchor might differ by protocol and may require non-public information to identify who exercises real control.

makerDAO's swift 48‑hour adjustments to debt ceilings and collateral during the March 2023 turmoil illustrate operational responsiveness, but the same concentration can create single points of failure and incentives that may not align with broader community interests.

Analysts warn that concentrated voting power raises the chances of market manipulation, collusion, or capture by a small number of actors.

Regulators are likely to view this as a challenge to the rhetoric of fully decentralized DeFi and may intensify scrutiny as MiCA implementation nears.

The ECB's framing of DeFi accountability problems and the data gaps surrounding ownership point to a future where regulation targets identifiable control nodes rather than the idea of decentralization itself.

The analysis puts real-world bite on MiCA debates by focusing on governance centralization and its regulatory implications.

The paper notes that the work reflects researchers' views, not ECB policy, and calls for more on-chain transparency and DAO legal clarity.

Regulators will watch how protocol teams respond, especially as MiCA timelines tighten and enforcement expectations grow.

The piece also highlights that governance centralization raises accountability questions about who controls protocol decisions and how that maps to legal oversight.
