Sei uses a multi-chain setup to support every stage of the development lifecycle — from early testing to live deployment. This approach helps developers build, test, and iterate with confidence.
Update Flow:
All updates are first rolled out onDevnetfor stability checks, then pushed toTestnetfor broader testing and validation. Only after passing these stages are updates released toMainnet.
This structured rollout ensures a safer development process, giving teams time to test thoroughly and provide feedback before any changes go live.
Sei offers multiple environments to support safe and efficient dApp and smart contract development:
A public staging environment that closely simulates mainnet conditions.
Use it to test apps in a real-world setup before going live.
