Insolar MainNet will undergo maintenance on December 23 at 12 PM UTC due to the rollout of the new software release. The expected downtime is 3 hours. During the downtime, Insolar MainNet Wallet works in a read-only mode: Users can log in, check the current account balance and deposit account details. Users cannot create new wallets, transfer XNS between wallets and from deposit accounts to current accounts. All these operations result in a corresponding error in the Wallet’s web interface.
