Starknet v0.13.0: Support for Fee Payment in STRK, Reduced Transaction Fees

Starknet v0.13.0’s deployment on testnet is a significant milestone, emphasizing two pivotal advancements. Firstly, the introduction of V3 transactions marks a transformative shift by allowing fee payments in STRK alongside ETH, leveraging oracles from Pragma and Switchboard. This flexibility opens avenues for upcoming features, such as the Fee Market, Paymaster, and Volition Mode, designed to enhance user experience and adaptability. Secondly, transaction fee reductions, notably the 50% reduction in Cairo step/builtin costs and L1 data availability improvements, underscore Starknet’s commitment to efficiency. With these strides, Starknet v0.13.0 lays the foundation for a more versatile and cost-effective decentralized ecosystem. :point_right: :point_left:
