How could we shutdown storage node and receive the rest of held amount without zksync?
Hello @storage1 ,
Welcome to the forum!
You can perform the Graceful Exit, if your node older than 6 months: Graceful Exit Guide
However, the outstanding payout will still be a subject of Minimum Payout Threshold on L1 (Ethereum). If the proposal
would be in effect, you unlikely may see your payout on L1 for a long time, unless fees on Ethereum would drop enough.
So, I think there is no other reliable option except zkSync to receive a final payout.
