We’re updating you about your zkSync Lite account.
The team behind zkSync Lite have advanced to the next stage of their roadmap, a new network called zkSync Era. As part of this evolution, they’ve stopped developing zkSync Lite.
Consequently, the dapp partners that enable the ‘Invest’ section of our zkSync Lite account have also stopped supporting the network. Soon, the ‘Invest’ section will be unavailable.
To ensure a smooth transition, we strongly recommend moving your assets off zkSync Lite.
