Hello, this is my first post on this forum. I’m active on Reddit’s r/ethfinance and I just learned about this place today.
I’m pretty sure I just lost everything on oasis.app. I heard they launched DAI on arbitrum today, so I tried depositing my ETH on arbitrum into my vault and generating DAI. I did this by opening my vault and switching over to Arbitrum in Metamask. Under collateral, where you deposit ETH, it told me my balance, so I deposited my ETH, just like normal. It’s not showing up in my vault. There’s no DAI generated either. On my transaction list, it just shows up as a send to this address.
On r/ethfinance, the posters there helped me figure out that this address is the arbitrum version of my vault on the ethereum mainnet. I don’t know if there’s anything that can be done, but I’m posting here on the off chance that it’s possible.
EDIT: Here’s an update that will hopefully more clearly explain what happened. It includes a video showing the steps I went through when I made the original deposit. Depositing ETH into a Maker vault on Arbitrum - YouTube
Just to go through the steps, since I probably didn’t communicate clearly earlier:
I connected my metamask to oasis.app with metamask set to Ethereum Mainnet, same as I’ve done probably dozens of times.
In Metamask, I switched from Ethereum Mainnet to Arbitrum, same way I’ve done on Impermax, Sushiswap, etc.
Just like on Impermax, Sushiswap, and other projects, when I switched Metamask to Arbitrum, oasis.app showed my ETH balance on Arbitrum. At the time, that balance was a little over 63.56 ETH.
Seeing my Arbitrum balance, and hearing that DAI was now available on Arbitrum, I thought vaults were now available on Arbitrum as well
I deposited 63 ETH and clicked confirm. I should have sent a test transaction, however after using my vault without problems for years, I didn’t think to do so.
Now that ETH is gone.
Note, in the video, that when I switch between networks in Metamask, the amount of ETH available to deposit in oasis.app changes. On Mainnet, I now have a little over .54 ETH. On Arbitrum, after losing my 63 ETH, I now have a little over .56. I’m point it out because there’s only a .02 difference between the numbers, so I want to make sure you guys don’t miss it.
If you’re reading this and you have a Maker vault, DO NOT SWITCH TO ARBITRUM AND TRY TO DEPOSIT. It will allow you to do so, but you will lose your ETH.
This was literally everything I had in the world besides my car. I’m not posting for sympathy, I just want everyone to know so it doesn’t happen to them, and because I said I’d keep everyone updated. I know I’m the one who made the transaction. I take responsibility for that. But I do think, if Maker doesn’t support vaults on Arbitrum, they should disable deposits if your wallet is set to Arbitrum. That’s what projects like Impermax, Sushiswap, and even ArbiNYAN do
