Smart technology in blockchain refers to automated, self-executing systems that enhance efficiency and security. The most notable innovation is smart contracts, which facilitate decentralized finance (DeFi), NFT transactions, and automated token swaps without intermediaries. Smart technologies are integral to Web3 infrastructure, AI-powered crypto trading, and automated governance in DAOs. Investors track smart contract audits, gas fee optimizations, and Ethereum Virtual Machine (EVM) compatibility when assessing blockchain ecosystems. The evolution of smart wallets, smart oracles, and smart legal agreements continues to revolutionize digital interactions.
