Starknet v.0.13.6 Mainnet
Starknet will release version 0.13.6 on June 30 to Testnet and on July 8 to Mainnet. This update lays the groundwork for integrating S-Two, StarkWare’s next-generation STARK prover, which significantly reduces proving time (to under 3 minutes for 2B L2 gas blocks) and cuts costs by at least half. While S-Two is not yet live, v0.13.6 introduces key compatibility changes while retaining the current transaction costs and UX. Cairo Native is temporarily disabled on Testnet but will be reintegrated later in Q3.
