Layer-1 Blockchain Cryptos Dominate Market with BTC and ETH Leading the Way
The top Layer-1 blockchain cryptos in September 2026 are dominated by established players like Bitcoin (BTC) and Ethereum (ETH), but other projects are gaining traction.
BTC, with a market capitalization of $1.56 trillion, remains the largest Layer-1 crypto, while ETH, at $296.89 billion, is the second-largest. BNB, TRON (TRX), Solana (SOL), and Cardano (ADA) also feature in the top 10.
The growth of blockchain adoption has pushed Layer-1 networks to improve their capabilities, addressing challenges around scalability, transaction speed, and efficiency. Projects like Hyperliquid (HYPE) and Zcash (ZEC) are designed with a strong focus on decentralised trading infrastructure and privacy, respectively.
