Cryptocurrencies with the smartest contracts?

Ethereum remains the biggest smart contract platform in the crypto space. However, it is facing stiff competition from blockchain protocols like Solana (SOL), Cardano (ADA), and Avalanche (AVAX).

If you meant the cryptocurrencies with the highest number of deployed smart contracts besides Ethereum, with 320 protocols, Binance Smart Chain has the highest number of protocols which translates to smart contracts. Ethereum has 550 smart contract protocols and commands the highest value of any blockchain. It is the first blockchain with a programmable layer established as a decentralized computer for applications with limitless potentials.
