Smart contracts improve efficiency by automating tasks and reducing the need for intermediaries. In finance, they speed up transactions by directly executing predefined conditions without banks. In supply chains, they ensure timely payments and shipment processing, enhancing transparency and reducing delays. In real estate, smart contracts automate property transfers, eliminating paperwork and legal complexities. In insurance, claims are processed faster based on data inputs, minimizing fraud and administrative work. By executing automatically on blockchain, smart contracts increase reliability, reduce errors, and cut operational costs, making processes more efficient and transparent across industries.
