Summary

This report presents the latest modifications to the Bifrost Network's Node. The key highlight of this new version is the transition in Substrate and Frontier from bifrost-polkadot-v0.9.39 to bifrost-polkadot-v0.9.43. As a result of this update, we've now achieved the version immediately preceding the significant new release, polkadot-v1.0.0. Additionally, this update enhances the robustness and reliability of in-built EVM (Ethereum Virtual Machine) while setting important benchmarks for upcoming functionalities.

⚠️ Please note that upgrading your Bifrost Node client is mandatory for Full Nodes after a runtime upgrade occurs. If you’re operating a full node or a relayer on our Mainnet or Testnet please check the runtime upgrade schedule below. If the client has not been upgraded, precompiled contract interactions requested to your node will always fail.
