Waiting for @penumbra23 thumps up

@Haider-Ali-DS @Lohann Should we "fix" Astar as well, if metamask uses a 60 for them as well? Are there other wallets that use the correct coin identifier?

[Lohann]

The issue is that we also use the BIP44 ID for Astar SS58 address, the issues is that if you import a mneumonic on Metamask, it will derivate the wallet from 60, if you import it on PolkadotJS extension, it will use a different derivation.
