### Features

* (types) [#19281](https://github.com/cosmos/cosmos-sdk/pull/19281) Added a new method, `IsGT`, for `types.Coin`. This method is used to check if a `types.Coin` is greater than another `types.Coin`.
* (client) [#18557](https://github.com/cosmos/cosmos-sdk/pull/18557) Add `--qrcode` flag to `keys show` command to support displaying keys address QR code.
* (client) [#18101](https://github.com/cosmos/cosmos-sdk/pull/18101) Add a `keyring-default-keyname` in `client.toml` for specifying a default key name, and skip the need to use the `--from` flag when signing transactions.
* (tests) [#17868](https://github.com/cosmos/cosmos-sdk/pull/17868) Added helper method `SubmitTestTx` in testutil to broadcast test txns to test e2e tests.

The implementation of IsGT method correctly checks if the receiver Coin is of greater value than the other Coin instance by comparing their denominations and amounts. However, using panic for handling different denominations is not ideal for production code as it can cause the application to crash. Consider returning an error instead, which allows the caller to handle this case more gracefully.

- panic(fmt.Sprintf("invalid coin denominations; %s, %s", coin.Denom, other.Denom))
+ return false, fmt.Errorf("invalid coin denominations; %s, %s", coin.Denom, other.Denom)
