Decentralized Finance (DeFi) is grappling with a 'super user' issue, according to Messari analyst cereal_killer. Over the past year, the top 20 wallets accounted for 32.1% of all borrowing on Aave, while the top 10 wallets generated more than half of the trading volume on Uniswap V3 within a week. This concentration mirrors early trends seen in Robinhood, where by the end of 2022, only 13% of users engaged in options trading, yet this activity generated over 60% of the company's revenue. Unlike traditional fintech platforms like Robinhood, DeFi's open-source nature allows for rapid protocol forking and liquidity migration, often through 'vampire attacks.' Collaborations, such as those between Morpho and Coinbase, may offer solutions to this concentration problem by potentially redistributing activity more evenly across users.
