Introduction:
This report provides transparency regarding the network changes executed on the Avail Mainnet, focusing on the Vector bridge updates.
The existing Vector bridge was not compatible with the upcoming Ethereum Pectra upgrade, so changes were necessary to ensure its functionality.
Executed Changes:
Instead of using TelepathyX in our bridge process, we switched to SP1 Helios and added new extrinsics to the vector pallet to ensure that the Ethereum → Avail bridge continues to function after the Pectra upgrade is completed.
Code Modification:

PR: Add support for sp1 v4.0.0 by 0xSasaPrsic · Pull Request #713 · availproject/avail · GitHub
Merits to the Network:
The upgrade ensures seamless operation of the Vector bridge with the upcoming Ethereum Pectra upgrade.
