Solana Begins Testing on Major Speed Upgrade: SOL Price to $150?

Solana (SO) is changing hands near $117, down 0.78% on the day, as the network’s biggest structural overhaul in years quietly clears a critical testing milestone. There’s a number buried in this story that traders chasing the next leg up need to see before they place another order.

Developers have pushed the Alpenglow upgrade to Solana’s public testnet, targeting a reduction in transaction finality from roughly 13 seconds to 0.15 seconds, replacing the current TowerBFT consensus mechanism with a new voting protocol called Votor.

Validators running Agave 4.3 can now test the migration on a live copy of the network without risking real funds, following more than four months of trials on a dedicated test environment.

Anza, the firm maintaining Agave, confirmed the move via its feature-gate tracker, and mainnet activation is currently penciled in for around September 28.

The timing matters. Spot Solana ETFs pulled in $26.1 million in net inflows on September 21, and network usage metrics, 23.2 million x402 AI-agent transactions in the trailing four weeks, suggest institutional and application-layer demand are both building into the upgrade window.

Can Solana Price Hit $150 This Week?

SOL USD price is testing the lower edge of a resistance band between $116 and $123.35, a level it needs to clear decisively to open the path toward $137.65 and eventually $144.76.

The four-hour RSI sitting near 71 tells a mixed story: momentum is real, but that reading also flags a market getting stretched, one where a pullback wouldn’t be surprising.

Support sits around $114.67, with a deeper floor near $106.95 if sentiment sours.

It is worth flagging buying walls at $123 and $132, with $150 emerging as the consensus upside target if both levels give way.

The base case has SOL grinding against resistance into the September 28 Alpenglow activation, using the catalyst as the trigger for a breakout attempt.

The bear case: a rejection at $120–$123 sends price back to retest $114.67, delaying the $150 conversation.

Watch volume on any resistance test, a low-volume push through $123 would be far less convincing than one backed by real size.

LiquidChain Targets Early Mover Upside as Solana Tests Key Levels

Anyone holding SOL from the sub-$100 range is sitting comfortably. But buying in now, chasing a token already up 22.57% over seven days and pressing into resistance, is a different risk calculus entirely, the easy money on this leg has largely been made.

That’s pushing some traders toward earlier-stage plays with more room to run, and cross-chain infrastructure is one of the more active corners of that search right now.

LiquidChain (LIQUID) is building a Layer 3 execution environment designed to fuse Bitcoin, Ethereum, and Solana liquidity into a single unified layer — a “deploy-once, access-all” model for developers tired of fragmenting liquidity across chains.

The presale is priced at $0.014958 per token, with $971,680.17 raised to date. Core features include single-step execution and verifiable settlement, aimed at removing the friction of bridging between ecosystems. As with any presale, there’s no secondary market yet and no guarantee the mainnet delivers on the roadmap, due diligence matters here.

Key Takeaways

• SOL must clear $120–$123.35 resistance to realistically target the $132–$150 zone flagged by analysts.
• A rejection at current resistance risks a retest of $114.67 support, or deeper to $106.95 on heavier selling.
• LiquidChain’s unified liquidity layer targets BTC, ETH, and Solana interoperability, with presale pricing at $0.014958.
• Alpenglow’s mainnet feature-gate activation, expected around September 28, is the next major catalyst for SOL price action.
