SIMD-0296 Larger Transaction Size

ReviewCoreStandardcreated 2025-05-28

Authors: jacobcreech, apfitzge

Historically, messages transmitted over the network must not exceed the IPv6 MTU size to ensure a fast and reliable network delivery. Solana has used a conservative MTU size of 1280 bytes, which after accounting for some of the overhead, leaves a maximum transaction size of 1232 bytes for data in the payload.
