Solana activates Transaction V1 on mainnet, raising size limit 3.3x
- —Transaction size limit raised from 1,232 to 4,096 bytes (a 3.3x increase)
- —Mainnet activation took place on September 15 at epoch 1035
- —The upgrade was implemented under SIMD-0296 and SIMD-0385 by Anza and the Solana Foundation
- —The v1 format is optional, with legacy and v0 formats retained
Why it matters: The expansion opens the door to zk-proofs and complex DeFi operations in a single transaction, but requires RPC providers and indexers to update.
