* `sdk.Msg` now only contains `ValidateBasic` and `GetSigners` methods. The remaining methods `GetSignBytes`, `Route` and `Type` are moved to `legacytx.LegacyMsg`.
|
||||
* The `RegisterCustomTypeURL` function and the `cosmos.base.v1beta1.ServiceMsg` interface have been removed from the interface registry.
|
||||
* (codec) [\#9251](https://github.com/cosmos/cosmos-sdk/pull/9251) Rename `clientCtx.JSONMarshaler` to `clientCtx.JSONCodec` as per #9226.
|
||||
* (x/bank) [\#9271](https://github.com/cosmos/cosmos-sdk/pull/9271) SendEnabledCoin(s) renamed to IsSendEnabledCoin(s) to better reflect its functionality.

## Blocklisting Addresses

The `x/bank` module accepts a map of addresses that are considered blocklisted

from directly and explicitly receiving funds through means such as `MsgSend` and
|

`MsgMultiSend` and direct API calls like `SendCoinsFromModuleToAccount`.

outside the expected rules of the state machine, invariants are likely to be

By providing the `x/bank` module with a blocklisted set of addresses, an error occurs for the operation if a user or client attempts to directly or indirectly send funds to a blocklisted account, for example, by using [IBC](http://docs.cosmos.network/master/ibc/).
