Kaspa's smart contract launch on August 31 and Arbitrum's Callisto upgrade are boosting DeFi capabilities, while Dogecoin gains traction with potential ETF approval. These projects combine real-world adoption—like Dogecoin's 50,000+ daily transactions—with active development, solidifying their positions as leading altcoin opportunities.
