Aya testnet went public in February 2023.
Aya is the sidechain that will run in every EarthNode, allowing ENOs to take part in the sharing economy and change the world. This is the next step in realising World Mobile’s version vision to connect the unconnected.
The community will be able to assist you on Discord in the 'en-public-testnet' thread. We would highly recommend asking any questions there and our team and the community will be able to assist you.
