Solana more than triples transaction size limit with mainnet upgrade
Solana raised its transaction size limit to 4,096 bytes, giving developers more room for zero-knowledge proofs and transactions with multiple signatures.
Solana raised its maximum transaction size from 1,232 bytes to 4,096 bytes to allow developers to fit more complex operations into a single transaction, including zero-knowledge proofs and new onchain signature schemes.
The upgrade was activated on mainnet on Tuesday at the start of epoch 1,035 around 1:00 am UTC, according to blockchain data shared by the Solana Foundation.
