Hello Metamask Community!
I need some help. The first metamask I ever created last year cannot be accessed anymore. I still have NFTs there, P2E games and some coins/tokens in the wallet. When I installed the new Opera crypto browser, I decided to transfer my BSC activity from Microsoft Edge to the new browser. I deleted the Metamask in Edge since I was confident that I had the seedphrase correctly written in my notebook. When I tried to import my seedphrase on the new Metamask in Opera crypto browser, it says invalid seedphrase. Tried many times. After that, I reinstalled the Metamask extension in Edge to try to enter my seedphrase there again, it also says invalid. Tried entering in different wallets, says invalid. I tried to do 1st way which is the console access in the browser but since I reinstalled a new metamask in Edge, it cannot recover the vault details anymore. Tried to pull up the 00003 file in my PC folders, the past version of the 00003 file was not there anymore since I already installed a new Metamask in my Edge browser. Tried using Easeus file recovery software, it cannot also find the old 00003 file before the new Metamask extension installed in Edge. Is there any other way to recover it or should I move on and press F for respect to my wallet and it’s funds?
PS: this was my first time migrating my entire chain activity from one browser to another.
Yes. But even in chrome, my seed still is invalid. One of my friends said my wallet has a lot of activities in BSC but is not considered registered on-chain since it didn’t have any activity in Ethereum chain.
What if you tried to install another wallet than Metamask and see if it works. If another wallet also says invalid seed phrase, then the problem is not with Metamask, but could be your seed phrase.
There can be number of reasons why your seed is Invalid , either the sequence of words is incorrect or some words maybe spelled wrong or you are placing more than one phrase in the wallet. Please try to write them in the sequence and also try to use dictionary to check the spelling of words that you doubt, as well as check if you are giving space properly. Moreover when you type seed phrase click on the option show the phrase while typing, in this way it will be visible to you and you will identify the problem.
There are so many issues in Metamask about losing assets! mine was lost without doing anything! just missed to open my MM in five days then when I opened it after that days, I found out the assets (VIS, MATIC, PGX & USDT) are gone.
