According to the latest announcement from the Layer 2 project built by the Kraken team, the project has officially started to open the testnet for users to experience the product.
However, at the moment, this testnet will only be available for builders on Layer 2 and has not yet fully opened the experience of Dapps for users. Users can currently only perform testnet activities such as Bridge ETH to Ink from other testnet networks or create a Smart Contract for themselves.
Ink is developed based on the OP Stack tools of Optimism and has now become a member of the Superchain ecosystem.
