The Ethereum Rollup ecosystem could benefit from a unified programming interface to streamline developer migration. Currently, diverse Rollup solutions like Optimism, Arbitrum, and zkSync use distinct APIs, SDKs, and tooling, creating friction for developers switching between them. A standardized interface would abstract these differences, enabling seamless code portability and reducing learning curves. This could accelerate adoption, foster interoperability, and encourage innovation by allowing developers to focus on building rather than adapting to platform-specific nuances. However, enforcing uniformity risks stifling the flexibility that drives Rollup innovation. A balanced approach, such as a modular interface with optional compliance, could align ecosystem growth with developer freedom.
