Marko Upetr focused on enhancing cross-chain readiness by improving EVM integration within the onflow/flow repository. Over the course of a month, he updated sprint planning to prioritize EVM-related tasks, replaced Geth forks to streamline compatibility, and introduced reconnect logic to bolster bridge resilience. He also synchronized JSON-RPC API specifications across flow-evm-gateway and flow-go, ensuring consistent communication between services. Marko’s work relied on Markdown for documentation and project management, emphasizing clear process alignment. While the scope was limited to a single feature, the depth of integration and attention to interoperability laid groundwork for stable, future cross-chain functionality.
