v0.73.0

Overview

This release introduces transaction pool functionality to address nonce management challenges, where rapid transaction submissions could result in incorrect nonce calculations and transaction failures. The new transaction pool tracks pending transactions per address, enabling proper nonce prechecks in eth_sendRawTransaction and accurate responses for eth_getTransactionCount with "pending" block tags.

Other key API improvements include enhanced validation for eth_getBlockReceipts, enabled jumbo transaction feature for larger payloads, CREATE2 opcode fix in debug_traceBlockByNumber, proper to = null returns for contract deployments in eth_getTransactionByHash, and removed caching logic for eth_gasPrice to provide real-time gas price information.

Additional updates include LayerZero HTSConnector improvements, debug trace fixes for transactions without internal calls, security enhancements via StepSecurity, migration to ESLint v9, and numerous dependency updates through Dependabot.
