Solana (SOL) has emerged as a standout performer in the altcoin market, surging to $114 with a 9% weekly gain and breaking above key resistance levels. The token's SOL/ETH ratio is up 4%, signaling stronger relative demand for Solana versus Ethereum as Bitcoin reclaimed $80,000. According to AMBCrypto, this performance comes as TOTAL3 has moved back above $800 billion for the first time in more than eight months, while 70% of Binance-listed altcoins are now above their 200-day moving average. The technical setup suggests SOL is not just riding the broader altcoin rotation but attracting relative demand as capital rotates away from Bitcoin, with the SOL/BTC ratio up more than 4% as Solana dominance broke above 2.3%.
Institutional adoption is providing significant support for Solana's rally, with U.S. Spot Solana ETFs recording $47.62 million in net inflows on September 18, according to SoSoValue. The entire inflow came through the BSOL ETF, suggesting the move is being supported by fresh demand rather than just rotation from other altcoins. This institutional backing aligns with the broader altcoin momentum return, as 70% of Binance-listed altcoins are now above their 200-day moving average, indicating that capital is rotating back toward alternative assets after nearly a year of grinding weakness.
Solana's network has achieved unprecedented activity levels, with 5.2 billion non-vote transactions recorded in August, reaching an all-time high according to Blockworks data. This activity increased by 19% compared to the previous record set in July, demonstrating robust user engagement on the network. Memecoin-related activity has been a significant contributor, with weekly Spot volume amounting to $5.2 billion, representing the highest level since November 2025. This record network activity provides fundamental support for SOL's price momentum and suggests the token is gaining strength beyond the broader altcoin rotation.
Solana's technical indicators continue to support the bullish outlook, with the token trading above all four major moving averages. The 20-day simple moving average at $101.87 provides the nearest dynamic support, while the 4-hour RSI reached 71.37, placing the token in overbought territory above the commonly watched threshold of 70. The average directional index registered 41.91, with an ADX reading above 25 typically pointing to a strong trend. However, the Awesome Oscillator remained slightly below zero at about -0.76, with negative bars contracting, suggesting that bearish momentum was losing strength as SOL recovered from $96. The current setup suggests SOL has the technical strength to extend its rally and potentially lead the broader market into October.
Solana successfully activated its Transaction V1 upgrade on September 15, increasing the maximum transaction size from 1,232 bytes to 4,096 bytes - 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. While the upgrade significantly expands transaction capacity, it does not change network speed, throughput, or fees. The larger format allows developers to place more instructions, signatures, and data into a single atomic transaction instead of splitting complex operations across multiple transactions. The upgrade supports workloads that were difficult to fit under the former 1,232-byte limit, including zero-knowledge proofs, large multisignature wallets, and other data-heavy operations. With growing dominance, stronger relative performance, new institutional inflows, and record network activity, the technical setup looks increasingly compelling for Solana to extend its rally and potentially lead the broader market into October.
