00 Why does my trading bot's wallet lock until the next epoch?
I've been having an issue where my trading wallet, which uses a bot, often receives an error saying 'Failed to sign transaction by a quorum of validators...' This results in the wallet being locked until the next epoch, sometimes for hours. It appears especially after an RPC timeout during a transaction. Why does this happen, and how can it be fixed to avoid such long locks?

How to transfer SUI from Standard wallet to Ledger wallet?
I've connected my Ledger to a newly created SUI wallet, and that worked out fine. Now, I want to transfer my SUI from my 'Standard' SUI wallet to my 'Ledger' SUI wallet. Is there a shortcut, or do I have to send the SUI from one address to the other, like sending tokens to exchanges? I want to ensure this process is secure.

01 Does Sui support contract self-destruction?
I was wondering if there's a way to destroy or self-destruct a smart contract within the Sui framework. I heard something about a 'selfdestruct' mechanism and wanted to know if it exists in Sui. Also, what would happen if a contract is terminated in this manner?
