2031Lost USDC transferring from Slush to Binance, any recovery tips?
I transferred USDC from my Slush wallet to Binance using Aptos but haven't received it. I was told the tokens are lost because I didn't use the Sui chain. Is there any way I can refund or recover my USDC?

What happens to blobs after they hit the end epoch?
I was wondering what exactly happens to blobs on the Walrus network when they reach their end epoch. Do they just disappear? Or can I get back some of the storage costs if I've marked them as deletable? Also, how does the whole lifecycle of these blobs work, especially in terms of storage reclamation?

01What happens to data after the 'end epoch' in Wal framework?
I was learning about the Wal framework's 'writeBlob' function which requires setting a 'start epoch' and 'end epoch'. I'm curious, what happens to the stored data after the 'end epoch' is reached? Does it get deleted automatically, or does something else happen to ensure data continuity?

01How to update a merchant's key in ObjectTable when it changes in the struct?
Hi everyone, I'm just getting started with writing smart contracts and I'm working on my very first project. I'd love some help with an issue I'm stuck on. So far, I’ve created a Merchant struct that looks like this: id: a unique identifier (UID) owner: the address of the merchant key: a String used as a unique key balance: a u64 representing their balance I also made a MerchantRegistry struct to manage all merchants: id: another UID merchant_to_address: an ObjectTable mapping addresses to merchants merchant_to_key: an ObjectTable mapping keys to merchants I want to be able to look up a merchant either by their address or by their key. When a user updates their key inside the Merchant struct, the change doesn’t automatically update the key in the merchant_to_key table. That means the old key still points to the merchant, which breaks things. I tried removing the entry from the table and inserting it back with the new key, but I keep running into errors like: "Cannot ignore values without drop ability" I'm pretty sure this is a beginner mistake, but I haven't been able to find a clear explanation or solution anywhere. Is there a proper way to handle updating the key in both the struct and the lookup table?

00How can I stake my SUI with flexibility to unstake anytime?
I'm new to SUI and want to stake it for potential rewards like airdrops. I'm looking for a way to stake my SUI that allows me to unstake whenever I want. Can I do this directly from a Phantom wallet or through SuiLend, and what might be the differences?

01Can you view USDC in Ledger Live or only through browser?
Hey everyone, I'm trying to manage my USDC using Ledger Live app. I was wondering if we could directly see the USDC balance in the Ledger Live app, or is it that for managing USDC and Sui, we need to use the browser connected to our Ledger device? I know for some tokens like SOL and ETH, you can see them directly, so I'm hoping for something similar.

01Can I store NFT metadata and how to fetch it?
I'm working on an NFT project and I'm considering storing metadata for my NFTs. I'm curious if I can store this metadata externally and what the best practices would be for fetching it afterwards. Any advice would be greatly appreciated!

01Does deploying a site with Walrus make it live instantly?
I’m trying to wrap my head around deploying a site using Walrus. When I hit the publish button and deploy the site, does it immediately go live, or do I have to wait for one epoch before it appears online?
