"Stuck funds on Loopring L2 - Ledger Nano S "Only V4 supported" error - Cannot withdraw, send or export account" Hi everyone,
I'm desperately trying to withdraw my ETH from Loopring L2 to my L1 Ethereum wallet and I've been stuck for days. I'm hoping someone here has experienced the same issue and found a solution.
**My setup:**
- Ledger Nano S, firmware 1.9.17, Ethereum app latest version
- Connected to Loopring via MetaMask (Chrome)
**The problem:**
Every single operation that requires a signature on Loopring fails with this error:
```
{"code":-32603, "msg":"Keyring Controller signTypedMessage: HardwareWalletError: Ledger Only V4 supported"}
```
This affects **all** operations: Withdraw, Send, and even Export Account.
When I try Export Account (Settings → Security → Export Account) I get a different error:
```
{"code":700022, "msg":"Wrong private key"}
```
**What I already tried:**
- Enabled Blind Signing on Ledger ❌
- Updated Ethereum app to latest version via Ledger Live ❌
- Removed and re-added Ledger account in MetaMask ❌
- Loopring mobile app (no longer available on App Store) ❌
- Loopring Discord support channel (not accessible to new members) ❌
The wallet address matches perfectly between Loopring and MetaMask, so it's not a wrong account issue.
This seems to be a compatibility issue between Loopring's EIP-712 signing implementation and the Ledger Nano S through MetaMask, but I can't find any working solution.
Has anyone managed to solve this? Any help would be massively appreciated — my funds are completely stuck with no way out.
Thank you
