How to see if wallet on specific exchange is offline/suspended for maintenance?

[sky^walker]

Hi there,

I'm hoping someone could help me with a wallet maintenance problem.

The challenge: I need to know before I make a trade if the wallet of the crypto I'm about to trade is offline/suspended due to maintenance (if withdrawals/deposits are temporarily blocked/halted for that specific coin on that specific exchange).

My findings so far: I know that some exchanges make this information available on their website under balance/wallet/finance when you are about to make a withdrawal/deposit and very few also have a dedicated page showing this info.

Questions for you:
1. Do exchanges have APIs with wallet maintenance information? If so, which ones?
2. If an exchange does not have an API, what are some possible workarounds to solve this problem?

Thanks so much for your help

I think you need to checkout their announcement thread for the update about the wallet maintenance but most of the exchanges won't provide any information when there are some wallets are suspended and sometime the waiting time takes months to get used.So you need to check the reputation of the exchange before doing trade and also don't keep your coins for longer after the trade.

There are a few potential ways to knowing (not sure about using an API though):

• Check the exchange site of any announcement news about certain maintenance
• Check the deposit/withdraw section of the coin/token on the exchange. On some sites, it could be displayed as "under maintenance" or "suspended" or something along those lines
• Do a quick google search: "site name" + "coin/token name" + "maintenance"
• Check the exchange's Twitter account. There's a good chance that if a maintenance is under way, it would be announced there
• Last resort: Probably ask the exchange's telegram group

Disregarding the API (because I'm not aware of it).

The first thing I do is check if the exchange has a status page. This way you can see the status of all the wallets that are present in the exchange beforehand even without making an account. See some exchanges' status links below:

• Bittrex - https://bittrex.com/status
• Cryptopia - https://www.cryptopia.co.nz/CoinInfo/
• HitBTC - https://hitbtc.com/system-health

[I am not advertising any of the exchanges listed above, they are provided as an example]

If the exchange does not have a status page, then proceed with @mjglqw list.

Thanks everyone! That is very helpful!

So it seems there isn't a way to get the wallet status directly from the exchange without human intervention, right? (e.g. manually checking status page, twitter feed, etc)

I wonder if a possible workaround could be implemented via the blockchain. I say this will a limited technical knowledge but I'm hoping folks with a lot more know-how could shed some light. But if one had the wallet address for a specific coin on a specific exchange, given the ledger is public, would it be possible to pull the date of the last transaction for that wallet? If the last transaction was weeks/months ago, it is probably fair to assume this wallet is offline. Thoughts?

Ideally, I'd love to come up with a workaround (API is just one avenue) to get the wallet status in an automated way.

The more ideas the merrier

Thanks again!

Yes, it totally depends on the service on when to down the wallet for scheduled maintenance.

That is not fair. Most of the exchanges either provide new wallet/addresses for transactions or keep a dedicated address for every user. These details are obviously public and could be seen on any block explorers. I'm not sure what offline indicates here but technically it is never offline since money could still be sent to it and the details will always be on the chain.
