Smart Contracts

Smart contracts are programs that run on a blockchain and carry out agreed rules when specified conditions are met. They can manage digital assets, automate transactions, and coordinate services without relying on a central operator. Because deployed code may control valuable assets and can be difficult to change, correctness, security, and transparent behavior are important concerns throughout development and operation.

Open source tools in this area include programming languages, development frameworks, testing and fuzzing utilities, security analyzers, and formal verification systems. When choosing a tool, consider its supported chains and languages, maturity, license, maintenance activity, documentation, and fit with existing workflows. These tools are useful to developers, auditors, researchers, and organizations building or reviewing blockchain applications.
