Introducing Reactive Lasna

Today, July 28th, we’re thrilled to roll out Reactive Lasna, the new home for testing on Reactive Network. Lasna Testnet is now live and ready for developers to begin building and experimenting with smart contracts in a stable environment that closely reflects mainnet conditions.
Reactive Kopli, our previous testnet, is now officially deprecated. A heartfelt thank‑you to everyone who contributed to Kopli, whether by testing contracts, providing feedback, or helping others in the community. You’ve gotten us this far, and we’re grateful for every bug report and pull request!
