Crypto wallet provider Zerion has launched a test network for its upcoming Layer 2 Rollup ZERO Network. Developed using ZKSync's software package ZK Stack, the test network will be part of the expanding ZKSync ecosystem.The main ZERO Network is scheduled to launch later this year. Partners including 1inch, Philand and Dodo Finance are preparing to deploy on the ZERO test network and eventually go live on the main network. The team says it will fully support builders in the ZERO ecosystem, including free API credits and preferred placement within the Zerion wallet. This ZK Rollup network is essentially gas-free for users, allowing the use of any token to pay for the network. To accomplish this, Zerion has developed a customized payer contract to pay its wallet users for their transactions.
