Solana News: Transaction V1 Expands Capacity, Price Lags

Solana is back in the news as its maximum transaction size increased from 1,232 bytes to 4,096 bytes on September 15, a more than threefold expansion delivered through the Transaction V1 upgrade.

The feature was activated at the start of mainnet epoch 1,035 at approximately 01:00 UTC. SOL, however, showed no clear upward reaction to the news, trading modestly lower during a soft session across crypto.

The update gives developers more room inside an individual transaction, but it does not change network speed, throughput, or fees. So what does Transaction V1 do?

It allows developers to place more instructions, signatures, and data into a single atomic transaction instead of splitting complex operations across multiple transactions.
