Solana to increase single transaction limit to 4096 bytes

Solana plans to activate Transaction v1 this Wednesday, increasing the maximum capacity for a single transaction from 1232 bytes to 4096 bytes. This upgrade aims to support complex operations like large cryptographic proofs and multi-signature payments within a single transaction. While existing formats remain functional, service providers such as block explorers and wallets must update to support the new format. The 4096-byte limit is aligned with standard 4KB memory page sizes to optimize network performance and validator costs.
