Solana (SOL) Transaction v1 Upgrade Set for September 9 — Will SOL Hit $150?

Key Highlights

• Solana’s Transaction v1 upgrade is scheduled for September 9, expanding maximum transaction size from 1,232 bytes to 4,096 bytes.
• Adoption of the new format is voluntary — existing legacy and v0 transaction formats remain functional with current limitations.
• RPC nodes, block explorers, indexers, and other infrastructure services require software updates to prevent data display errors.
• SOL currently trades near $105, while liquidation data reveals concentrated liquidity zones between $145 and $150.
• Derivative open interest for Solana has recovered to approximately $6–7 billion, rising from the $4–5 billion levels observed previously.

Solana is gearing up to deploy Transaction v1 on September 9, representing a significant format enhancement that expands the maximum transaction size from 1,232 bytes to 4,096 bytes — delivering approximately 3.3 times greater capacity per transaction.

This enhancement stems from two separate proposals: SIMD-0296, which establishes the expanded size parameters, and SIMD-0385, which outlines the v1 format specifications. Both documents were jointly authored by Jacob Creech and Andrew Fitzgerald.

The expanded transaction capacity enables developers to bundle additional instructions, signatures, and account information within a single transaction. Practical applications include zero-knowledge proof verification, complex multisignature configurations, and cross-chain bridge operations.

Under the previous system, sophisticated operations required segmentation across multiple transactions, introducing execution risk. Individual transaction components could complete successfully while others encountered failures. Transaction v1 ensures all instructions execute or fail as a unified atomic operation.

Developer and Infrastructure Implications

Transaction v1 eliminates Address Lookup Tables, a compression mechanism used in v0 to condense account addresses into single-byte indexes. The new version stores complete 32-byte addresses directly within transactions, consuming more space per account while remaining within the expanded capacity limits.

The existing 64-account-per-transaction ceiling remains in effect. Developers must now explicitly configure compute-unit allocations and loaded-data thresholds in v1 transactions, as both parameters default to zero values.

Infrastructure operators face the most significant compatibility challenges. RPC service providers, blockchain indexers, explorers, and analytics platforms must implement software updates to accommodate version one transactions. Failure to update could result in transaction processing errors or incorrect data presentation — such as displaying zero priority fees when fees were actually included.

Jacob Creech, Solana Foundation’s VP of Technology, verified September 9 as the implementation target. However, the official development roadmap continues to list mainnet activation as pending confirmation, and Anza’s deployment timeline carries a tentative designation.

SOL Market Analysis and Price Action

SOL was changing hands at approximately $105.56 at press time, reflecting a modest 0.8% increase over the previous 24-hour period. The weekly Relative Strength Index has advanced to roughly 60, positioned above the neutral 50 threshold while remaining below the overbought zone above 70.

Solana (SOL) Price

Market analyst SatoshiOwl shared on X that SOL appears positioned for a potential breakout, with near-term price targets in the $115–$116 range. The analyst cautioned that if SOL reaches $116 amid extremely bullish market sentiment, traders should monitor for a potential sharp correction rather than expecting continued upward momentum.

CoinGlass liquidation heat mapping reveals substantial leveraged position concentrations between $145 and $150, with additional clusters identified near $180–$200 and $240–$250. Downside liquidity zones are positioned around the $60–$70 price levels.

Open interest in Solana derivatives markets has climbed back to approximately $6–7 billion, recovering from the $4–5 billion range observed during earlier phases of the market cycle, though remaining significantly below the previous all-time high near $17 billion.

According to the latest Solana Foundation status updates, both testnet and devnet environments have already enabled the Transaction v1 feature for developer testing and validation.
