Solana increases transaction size limit by 3.3x

Solana activated the v1 transaction format on its mainnet on September 15, raising the transaction size limit from 1,232 to 4,096 bytes. This update allows for the execution of ZK-proofs, complex multi-signature transactions, and batch operations within a single transaction. While legacy formats remain functional, applications and wallets must update to support the v1 format to utilize the increased capacity.
