COTI Testnet serves as an experimental environment for developers and enthusiasts to explore COTI’s native blockchain technologies. It enables users to test new features, smart contracts, and the stability of network protocols without affecting the Mainnet. The Testnet offers an accessible platform for simulating transactions and network behavior, aiding in the detection and resolution of potential issues before deployment on the Mainnet. This sandbox environment is crucial for enhancing the robustness and reliability of COTI’s ecosystem.

To facilitate testing, developers can obtain free tokens from the Testnet Faucet (next page). This allows users to perform transactions and execute smart contracts without incurring any costs.

Testnet runs the same code as the COTI v2 Mainnet, designed to provide a pre-production environment for developers about to move to Mainnet.
