Smart contracts are self-executing digital contracts that run on blockchain. They are programmed with specific rules and activate automatically when certain conditions are met, eliminating intermediaries and reducing costs. They are widely used in financial transactions, loans, insurance, and the buying and selling of digital assets. Thanks to their transparency and security, they minimize the risks of fraud and human error. Their adoption continues to grow in sectors such as real estate and logistics, enabling faster and more reliable agreements without the need for trust between parties.
