Sway
Sway is a smart contract development language and programming environment designed for writing, compiling, and deploying secure blockchain programs. It serves as a type-safe language for building on-chain logic and a static analysis toolchain that validates contracts before they are executed on a network.
The ecosystem provides a development environment focused on blockchain application logic and web3 backend engineering. It integrates a type-safe programming approach to reduce vulnerabilities and ensure reliable state transitions for decentralized services.
The toolchain incorporates static analysis and formal verification to prove the correctness of contract logic. It utilizes a strongly-typed front-end and a resource-constrained memory model to prevent runtime errors and resource exhaustion.
