 Verifying smart/token contracts is a crucial step in development, as it allows developers to ensure the contracts' correctness and security. Once verified, the contract's source code is made public, enabling independent verification, which fosters trust and transparency. This reassures users that the contracts operate as intended without any malicious code. It also simplifies the process for other developers to engage with your smart contracts.

 # Run Development Testnet
 
-While there is an established test network, namely the [Crab network](./crab.md), which serves as an ideal sandbox for your applications, eliminating any concern about initiating and connecting nodes, among other things. The official test network is designed to fulfill application developers' requirements. However, there may be scenarios where you want to perform low-level tasks. In such cases, creating your own development network can significantly enhance your development, testing, or debugging efficiency. This guide will walk you through the process of establishing a single-node development network.
+Darwinia no longer maintains a public testnet, so spinning up a local development network is the best way to experiment without risking production funds.
