Ongoing projects led by Loopring:

Loopring Protocol: powered by zkRollups on Layer2, enables Ethereum to scale effectively without sacrificing Ethereum Layer1 guarantees

Loopring via PC using Ledger (alien.top)

Hi, I've traded and used my loopring account through the loopring.io for a few years. I used to use a ledger to access it via metamask on chrome but recently it simply won't open giving me error messages such as

err_rest_eddsa_invalid_signature

error: web3.eth.personal.sign valid, valid 5 ways, all failed!

It offers a chance to reset key pair, this failed due to insufficient funds but seems to show i had more than enough eth to fund it.

I also tried to connect via ledger live using Wallet connect, at this point i saw a green accepted message Which then disappeared and was greeted by the red error messages from above. Then on subsequent attempts metamask wouldn't open and Ledger live stopped showing any connection at all lol

Anyway, possible causes -

1)i connected to a gamestop Wallet using the same ledger and brave browser a year ago. Had no problems accessing either account during that time.

i got a new pc near Xmas but am certain everything connected up fine. The last time i got into both accounts via loopring.io was 8 months ago

After trying lots of options i also updated all the firmware, Chrome, metamask , ledger live . No luck.

Any advice would be appreciated?

Edit - i did the hid device accepted thing as i found a single discussion about that somewhere on Reddit

Thanks but I've never used discord before unfortunately. But yes there's a ridiculous amount of dms coming from odd looking accounts 😂
