And developers, we want you to be part of it.
Overview of the Ink testnet
This invitation begins with the Ink testnet.
A testnet is an instance of the mainnet, used for testing and research purposes. Here, developers can deploy new products, look for bugs and hunt for vulnerabilities without real assets at stake.
The Ink testnet runs on Sepolia, an Ethereum proof-of-stake test network that mimics the functionality of the mainnet. Sepolia is the recommended testnet for Ethereum developers and is backed by the Ethereum Foundation.
Our testnet simulates the environment of the future Ink mainnet. It has a block explorer, ready-to-roll RPC endpoints, an easy-to-use bridge so you can bridge your Sepolia ETH to Ink, and a lot of other typical infrastructure you’ll find on mainnet.
We invite you to try it. Here are some resources to get started.
