CIP4 - Wallet checksum

I think we should have different or different type of plates for a wallet apps. E.g. Wallet (I would say Bank is more accure) plate, account plate etc.

I meant by wallet (as there are lot of different meaning, terms and definitions):
A banking like application (mobile Desktop etc.) for different cryptocurrencies e.g.

  • coins (a cryptocurrency that has its own blockchain, like ADA, BTC or ETH.) and
  • tokens (a cryptocurrency that is built on top of an existing blockchain e.g. any ERC20 tokens)

that are based on one or more coin specific Blockhains, but are derived from one common seed. For, simplicity, I excluded the wallets that uses different seed (mnemonics) for different coins.
E.g. a wallet can have BTC, ETH, ADA and other coins and their tokens in the same time even they all three use different blockchains, but uses the common seed.

Also, what is the plate number and wallet relationship in these case or the cases where the wallets can have different coins recovered from different mnemonics?
