TLDR
- Optimism returns to the market, focusing traders on altcoins with strong on-chain metrics.
- Sei (SEI) surpasses Bitcoin and Ethereum in monthly active addresses (12.9M) and offers fees of $0.0004.
- Arbitrum (ARB) shows signs of accumulation (“liquidity grab”) and analysts see upside potential in the L2.
Optimism is returning to the cryptocurrency market amid signs of a possible resolution to the prolonged US government shutdown. While Bitcoin (BTC) remains relatively stable, traders are beginning to refocus their capital on altcoins that demonstrate real on-chain strength.
In this scenario, two assets stand out for their on-chain fundamentals: Sei (SEI) and Arbitrum (ARB). Both present emerging technical and fundamental signals that could define the next wave of market rotation.
Sei (SEI) Impresses with User Growth and Efficiency
Sei Network continues to generate headlines as one of the fastest-growing blockchains. The latest on-chain metrics reveal 12.9 million monthly active addresses, catapulting Sei to sixth place globally and surpassing established players like Bitcoin (10.4M), Base (9.6M), and Ethereum (8.3M). This growth, nearly 200% since mid-2025, underscores the accelerated adoption of its high-speed, low-cost environment.
At the same time, Sei’s economic efficiency is proving to be a key competitive advantage. The network boasts the lowest average transaction fee among major chains: just $0.0004 per transaction. In comparison, Ethereum and Bitcoin sit at $5.70 and $5.50, respectively. This scalability has helped push Sei’s cumulative trading volume past $138 billion.
The SEI token has reacted positively, jumping more than 30% after confirming a 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.
Meanwhile, Arbitrum (ARB) is also seeing renewed investor interest after months of trading sideways. Analysts describe its recent price action as a “liquidity grab and reclaim” pattern, a classic setup where the market sweeps low levels before reversing upward.
On-chain data supports this thesis, showing that top wallets are increasing their exposure to ARB. Van de Poppe also identified a strong bullish divergence for ARB, describing it as one of the most promising Layer-2 projects, with the potential to outperform Bitcoin by up to 200%.
The simultaneous strength of Sei and Arbitrum’s on-chain fundamentals reflects a broader shift in market sentiment, with capital rotating toward high-performance ecosystems.
