Solana Expands Transaction Capacity with txv1 Upgrade

Solana has activated its txv1 feature gate on mainnet, raising the network's maximum transaction size from 1,232 bytes to 4,096 bytes. This change is part of a broader effort to increase throughput and support larger workloads on the network.

The increased limit allows for single atomic transactions that previously had to be divided into multiple chained transactions. This includes zero-knowledge proofs, large multisignature operations, and batched programs.

Node operators must upgrade their infrastructure to take advantage of the new transaction size. RPC nodes need to be on Agave v4.2.2 or later, while Jito-Solana validators also require a minimum version of v4.2.2.
