Optimism is returning to the cryptocurrency market amid signs of a possible resolution to the prolonged US government shutdown, with traders shifting capital to altcoins demonstrating strong on-chain fundamentals. Two assets, Sei (SEI) and Arbitrum (ARB), are at the forefront of this revival, showcasing impressive metrics and technical signals.
Sei Network (SEI) has emerged as one of the fastest-growing blockchains, with 12.9 million monthly active addresses, placing it sixth globally and surpassing Bitcoin (10.4M) and Ethereum (8.3M). This represents a nearly 200% growth since mid-2025, driven by its high-speed, low-cost environment. The network boasts the lowest average transaction fee among major chains at $0.0004 per transaction, compared to Ethereum's $5.70 and Bitcoin's $5.50, contributing to a cumulative trading volume exceeding $138 billion. The SEI token has reacted positively, jumping over 30% after a confirmed buy signal on the daily chart, currently trading around $0.183. Analysts like Michaël van de Poppe note that SEI is holding a crucial support level, suggesting potential for further gains.
Arbitrum (ARB) is also gaining attention after months of sideways trading, with analysts describing its recent price action as a liquidity grab and reclaim pattern. This setup involves the market sweeping low levels before reversing upward, supported by on-chain data showing top wallets increasing their ARB exposure. Van de Poppe identified a strong bullish divergence and views ARB as one of the most promising Layer-2 projects, with potential to outperform Bitcoin by up to 200%. Currently trading near $0.295, ARB's technical indicators, such as RSI hovering around 44, hint at strengthening momentum, with short-term targets set at $0.40 and beyond.
The simultaneous strength in Sei and Arbitrum reflects a broader market rotation toward high-performance ecosystems, signaling a shift in sentiment as capital flows into altcoins with robust fundamentals.
