Solana's native token, SOL, remained above the $110 mark on Saturday, September 19, following a sharp 10.8% rally that pushed it to a seven-month high. The digital asset traded at $110.15 at 22:19 UTC, down 2.2% from Friday's close but still up 8.4% from Thursday's level. The price action comes as the network activated its larger Transaction V1 format on mainnet, a technical upgrade that could expand the scope of applications built on Solana.
Market Context and Catalysts
Friday's surge saw SOL climb from $101.60 to $112.60, a gain of $11.00, with trading volume of $6.48 billion—more than double the $2.99 billion traded on Thursday. The session high reached $114.06. The move was part of a broader crypto rebound, as Bitcoin reclaimed the $80,000 level and other major altcoins followed suit. Short covering across the market added fuel to the rally, according to Yahoo Finance data.
Regulatory developments also provided tailwinds. On September 17, the U.S. Securities and Exchange Commission granted temporary, conditional relief for venues trading tokenized U.S.-listed shares. While the order does not single out Solana, it improves the policy environment for networks aiming to host tokenized assets, boosting sentiment for high-beta digital assets.
Transaction V1: What It Means
Solana's upgrade record indicates that the maximum transaction size has increased to 4,096 bytes from 1,232 bytes, a 3.3-fold expansion. The txv1 feature activated at the start of epoch 1035 on September 15. Existing legacy and v0 transactions remain compatible. This change allows developers to embed larger zero-knowledge proofs, multisignature instructions, and batched operations into single transactions, potentially simplifying complex financial applications.
However, the upgrade does not automatically translate to higher throughput or increased demand for SOL. Applications and wallets must adopt the new format, and users must choose services that leverage it. The Solana Foundation's August ecosystem report highlighted over $4 billion in real-world assets on the network, $500 million in xStocks assets, and $4 billion in cumulative tokenized-stock volume on Raydium, suggesting growing interest in financial use cases.
The Valuation Challenge
Despite the technical progress, fee data raises questions about the network's economic health. DeFi Development Corp.'s second-quarter shareholder letter, filed with the SEC, estimated that Solana processed 9.8 billion transactions in the quarter, up 9% year-over-year. Yet estimated network revenue fell 81% to $51 million, while application revenue dropped 78% to $198.6 million. Median transaction fees were 57% lower.
This tension underscores the rally's fragility. Lower fees can attract activity, but token holders need evidence that rising usage creates durable demand for block space and staking. If activity grows while fee economics weaken, the upgrade may improve the product without strengthening SOL's cash-flow-like fundamentals.
Key Levels and What to Watch
Immediate technical levels are clear: Friday's high of $114.06 serves as the first upside reference, while $101.60—the pre-rally close—is the downside test. Holding above $110 through weekend liquidity would preserve most of Friday's breakout, but price alone cannot confirm the upgrade thesis.
Investors should monitor three factors over the coming weeks: adoption of Transaction V1 by wallets and major applications, expansion of tokenized-asset and stablecoin activity, and whether network revenue improves alongside usage. The upgrade removes a technical constraint, but it has yet to prove that Friday's 10.8% repricing is attributable to Solana's fundamentals rather than a market-wide relief rally.
