PR Summary

Medium Risk
Changes EVM ante/address-association and block execution routing, which can affect nonce/account state and when blocks run sequentially vs OCC; mistakes could cause consensus or performance regressions under heavy transfer loads.

Overview
Improves EVM tx delivery performance by reusing preprocessed derived sender info in EvmDeliverHandleSignatures, skipping redundant signature recovery and validating derived pubkeys.

Adds a heuristic to detect large blocks (>=64) of simple value-only EVM transfers to a single recipient and forces sequential execution (including bypassing Giga OCC) to avoid OCC retry churn.

Optimizes EVM↔Sei association by reusing an existing empty “cast” BaseAccount (preserving account number/sequence) when safe, creating the Sei account if missing, and skipping balance migration when the cast and Sei addresses are identical; expands unit tests to cover these cases.
