Cosmos Labs has enabled modular signature adoption by sovereign chains and upgraded key management with features such as remote signing and rotation.
ATOM/USD trades with strong bullish momentum, rising 8.55% to $1.879, and is projected to consolidate between $1.8342786 to $1.9237214 over the coming days.

Quantum-secure upgrade boosts Cosmos' technical appeal and sentiment

Cosmos has released Ledger Security 2026.1, marking a significant upgrade with the introduction of native post-quantum ML-DSA signature support for both user accounts and validator consensus on its blockchain, according to Cryptotimes. This move future-proofs Cosmos' infrastructure by directly addressing emerging quantum security threats, which is likely to influence institutional and developer sentiment positively. Further, Cosmos Labs has enabled these signatures to be modularly adopted by sovereign chains and bolstered key management via remote signing and rotation features, as noted by Crypto Economy, broadening Cosmos' technical appeal and ecosystem integration.

Overbought signals and bullish momentum drive short-term volatility risk

On the technical front, ATOM/USD is trading above the MA-20 and MA-50 on the hourly timeframe, with the daily chart also showing price above the MA-200. The Ichimoku Kijun on the daily chart is providing immediate support at $1.775. Both MACD and ADX signal strong bullish momentum, while RSI, Stoch RSI, and CCI all register overbought readings. Bull/Bear Power confirms persistent buyer dominance intraday, and the Awesome Oscillator is also supportive of the ongoing upward trend. The oscillators’ overbought condition diverges from momentum signals, suggesting heightened short-term volatility and the potential for sharp intraday fluctuations should buying pressure abate.

Upside scenario favored as key support underpins range outlook

Over the next two to three trading days, ATOM/USD is expected to trade within the $1.8342786 to $1.9237214 range, with typical volatility clustered near the current session highs. There is a 79% probability of further upside extension, while downside risk remains contained at 21%, contingent on a hold above the $1.775 Kijun support. The baseline scenario calls for price consolidation inside this corridor; a decisive breakout above the range may open the door to fresh highs, whereas a drop below $1.775 would increase the risk of a pullback toward lower support levels.

Anton Kharitonov, expert at Traders Union, sees Cosmos' technical strength supported by the recent post-quantum security upgrade. He notes persistent bullish momentum, but highlights that overbought signals and possible volatility warrant caution. Base case is for consolidation within $1.8342786–$1.9237214, with focus on $1.775 support. "Until $1.775 is broken, I remain defensive and expect consolidation; any breakdown would shift my stance to bearish."

Earlier, analysts noted that Cosmos was experiencing positive short-term momentum supported by ongoing network development and heightened ecosystem activity. The current upgrade introducing post-quantum signature support further strengthens the technical foundation and adds a critical layer of security, with immediate attention warranted on price action near the $1.775 daily Ichimoku Kijun support as an inflection point for the prevailing bullish structure.
