# Smart Contracts > Overview: Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically execute and enforce the terms when predetermined conditions are met, without the need for intermediaries. Key Features: Automation: Smart contracts reduce the need for manual intervention, executing transactions automatically when conditions are met. Security: Stored on the blockchain, smart contracts are immutable and secure from tampering. Transparency: The terms of the contract are visible and verifiable by all parties involved. Applications: Finance: Automating loan agreements, insurance claims, and complex financial derivatives. Real Estate: Streamlining property sales by automating escrow and title transfer processes. Supply Chain: Automating payments and verifying the authenticity of goods as they move through the supply chain. Challenges: Complexity: Writing error-free smart contracts requires significant technical expertise. Legal Issues: Determining the legal status of smart contracts in various jurisdictions is complex. Scalability: Executing numerous smart contracts simultaneously can strain blockchain networks. **Published by:** [natali](https://paragraph.com/@natali/) **Published on:** 2024-06-10 **URL:** https://paragraph.com/@natali/smart-contracts ## Publication Information - [natali](https://paragraph.com/@natali/): Publication homepage - [All Posts](https://paragraph.com/@natali/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@natali): Subscribe to updates ## Optional - [Collect as NFT](https://paragraph.com/@natali/smart-contracts): Support the author by collecting this post - [View Collectors](https://paragraph.com/@natali/smart-contracts/collectors): See who has collected this post
