Solana to Triple Max Transaction Size on Wednesday to Support Complex On-Chain Operations

Solana is set to activate the Transaction v1 upgrade on Wednesday, expanding the maximum transaction size from 1,232 bytes to 4,096 bytes. This change aims to remove structural bottlenecks by allowing complex operations—such as large cryptographic proofs and multi-party approval payments—to be consolidated into a single transaction. The new format has been tested on devnet and testnet, and while it is backward compatible, data-reading services must update to prevent request failures or incorrect fee displays.
