Solana Introduces Triple‑Size Transactions and Faster Slots Amid Record Activity

Solana has launched two major performance upgrades as network usage reaches historic levels. The V1 transaction format, activated on Sept. 15, increases the maximum data size per transaction from roughly 1,300 bytes to 4,096 bytes, allowing developers to bundle more complex actions—such as privacy features, multiple signatures, or large account data—into a single, all‑or‑nothing transaction.

Key aspects of the V1 transaction format

• Payload capacity triples to 4,096 bytes.
• Supports up to 64 accounts directly within a transaction.
• Computing requirements and fee information are embedded in the transaction.
• Older formats remain functional, so immediate migration is not required.

Wallets, exchanges and other services must update their processing logic to recognize the new format as adoption grows.

Slot‑time reduction to 250 ms

Solana is also shortening the interval between slots, moving from the original 400 ms target to 250 ms. The change is expected to activate at 05:01 UTC on Sept. 18, marking the third reduction in the roadmap and leaving a final step to 200 ms on test networks.

• At 250 ms, the network can produce roughly four slots per second.
• At the eventual 200 ms target, production would rise to five slots per second.
• Shorter slots improve responsiveness but require validators to process and share blocks within tighter timeframes.

Record network activity

During August, Solana processed 5.2 billion non‑vote transactions, a 19 % increase over July’s 4.2 billion. Additional metrics highlight the surge:

• Weekly application revenue reached $40.8 million, the highest since January.
• Decentralized exchanges on Solana handled $16.59 billion in weekly volume, maintaining the chain’s lead in DEX activity.
• Daily active addresses interacting with stablecoins rose to 888,000 in September, 2.7 times the level a year earlier.
• Tokenized equities on Solana hit a supply of $684 million, up 47 % in three weeks.

These figures indicate that the record transaction count is driven by a broad mix of trading, stablecoin usage, and tokenized equity activity.

Outlook

The upcoming 250 ms slot transition will occur while Solana operates at these elevated usage levels. Successful implementation will set the stage for the final 200 ms target, further enhancing the blockchain’s responsiveness and capacity for complex applications.
