Uniswap (UNI) founder Hayden Adams has stirred up new controversy in the Ethereum community by questioning the blockchain’s approach to scaling and warning that Solana could gain the upper hand if DeFi continues to rely on Ethereum’s Layer 1. “If the plan is to do DeFi at Layer 1 or vertical scaling, Solana has the better roadmap, team, and approach,” Adams said in a post on social media, comparing the roadmaps of the two networks. His comments on Solana come amid ongoing debate within the ETH ecosystem over whether to continue prioritizing a rollup-centric Layer 2 (L2) strategy or reconsider more direct Layer 1 scaling improvements.
