Summary

• This week, we posted the EVM rollout plan for discussion, began testing the ETH connector prototype on TestNet, overcame blockers in the design of the EVM Bully stress-testing tool, and coordinated with the SputnikVM team regarding Berlin HF plans.
• Next week, we are planning to begin integrating the ETH connector with the EVM contract, begin ingesting the Eth1 Goerli testnet through the EVM Bully stress-testing tool, and validate the revamped EVM architecture using the Balancer and/or Anemone test suites.
