It is difficult to compare two powerful layer-1 blockchains like Solana and Avalanche. However, some differences exist, including transaction speed, smart contract layout, staking benefits, and even price performance. Solana offers 65K TPS as the transaction speed out of the box, whereas Avalanche, without the subnets, boasts 4.5K TPS. Yet, Avalanche feels superior in terms of development, courtesy of the EVM-compatible smart contracts.
