Solana is trading at roughly $85 at the time of writing, down about 2% over the past 24 hours. The price has stayed relatively stable despite broader market uncertainty.

Solana (SOL) Price

Price action shows SOL is stuck in a horizontal range, with $82 acting as a floor and $89 acting as a ceiling. Several rebounds off $82 suggest strong buying interest at that level.

However, each attempt to push above $89 has been turned back. That repeated rejection keeps the short-term outlook cautious.

Both the 50-day and 200-day moving averages are sitting above the current price. That positioning signals the broader trend is still slightly bearish.

The MACD indicator has flattened near the zero line. The histogram bars are shrinking, which means bearish momentum is fading — but there is no confirmed bullish crossover yet.

The overall picture points to a neutral-to-slightly-bullish bias, provided the $82 support continues to hold.

Analyst Ali Charts posted on X that SOL “could be setting up for a 10% move” as it approaches the apex of a triangle pattern. The analyst did not give a specific price target or timeframe.

Solana’s Quantum-Resistant Upgrade

On Monday, two of Solana’s main validator clients — Anza and Firedancer — announced they have implemented a test version of Falcon, a post-quantum cryptographic signature solution.

A new report on Solana’s quantum readiness is here, from @anza_xyz and @jump_firedancer.

Falcon was chosen because it produces the smallest signature size among the post-quantum standards selected by the US National Institute of Standards and Technology (NIST). Jump Crypto, the team behind Firedancer, said Falcon verification is straightforward to implement and that signing happens offchain.

The teams said the upgrade can be activated “if and when the time comes,” referencing what the industry calls Q-Day — the point at which quantum computers could break standard public-key encryption.

Both teams said they researched quantum solutions independently before agreeing on Falcon. Development records on Anza’s GitHub show work on Falcon began as far back as January 27, 2026.

Where Solana’s Ecosystem Stands

This is not Solana’s first quantum-related development. Blueshift’s Winternitz Vault has offered optional quantum security since January 2025, though it was not a protocol-level upgrade.

Anza and Firedancer confirmed that the Falcon implementation is now live in both teams’ GitHub repositories as an initial version.

Solana’s own social posts have focused on ecosystem participation, pointing to an upcoming Solana Ecosystem Call rather than price movements.
