Lovable for Anchor smart contracts

An AI-powered development tool that helps developers build, deploy, and test Anchor smart contracts. Features live reasoning visualization and secure containerized execution environments.

Built
  • •Built an interactive dashboard for sending prompts to an LLM backend and visualizing real-time responses.
  • •Created a futuristic landing and playground interface, combining high-performance React components with modern design.
Challenging (but overcame)
  • •Developed a parser and extractor system to display the LLM's live reasoning process in an intuitive UI.
  • •Designed a custom Kubernetes-based E2E environment to securely run Anchor build, deploy, and test commands in isolated containers.
