I just went through the process of creating a new Filfox wallet from scratch.
I then attempted to import into Glif, and it just says “invalid seed phrase”.
I successfully imported on Trust Wallet iOS, but again the address in Trust Wallet is different than the originally created Filfox wallet.
Same, with Private Key
Filfox lets you export the private key. I exported this private key and used that method in Trust Wallet to import, and got the SAME address as in the original FILfox. Great!
Tried import private key in Glif, and it gave me “Error: invalid key length”.
So, something is wrong with Filfox seed phrase / private key generation, that seems to be at least partially shared for private keys with how Trust Wallet does this.
