Our presentation will focus on the goals achieved, roadmap followed and challenges faced by us during the duration of cohort for this project.
## Goals Achieved
Pushed the client from 47/321 test cases passing to over 260 cases (as of 9/3/2026). That includes 100% success on RPC compatibility, signature verification, gossip, request & response and state transition suites.
## Roadmap
Mentioned in our project proposal [here](https://github.com/eth-protocol-fellows/cohort-seven/blob/main/projects/Grandine-Lean-Client.md)
## Challenges
We will be presenting the challenges faced during the testing, and specifically finding out about the test harness mismatch with image on hive dashboard and a few edge cases about some major test suites.
