Summary

Currently bech32 prefixes is a global in the cosmos-sdk and for applications as well. We should aim to remove most if not all globals within the sdk.

Problem Definition

Globals should be removed.

Work Breakdown

• replace account bech32 calls with calls into address codec for the prefix(s)
• replace validator key bech32 calls
• remove sdk.bech32 from types and outside modules
• Remove address verifier from global config, put it as argument to NewAccountKeeper
• Support cosmos.msg.v1.signer as alternative to Msg.GetSigners #11275
• Add a way for clients to get the bech32 prefix
• Go through every module and remove calls to .String() (this may require state migrations)
  • auth
  • authz
  • bank
  • feegrant
  • gov
  • groups
  • nft
  • distribution
  • staking
  • slashing
  • upgrade
• Deprecate all .String calls on addresses
• remove the need to set global codecs

Notes:

• do not call address.String() (SDK should not call address.String()  #8332)

Is there any other work we should mention here?
