 ### Bug Fixes
 
+* [\#9766](https://github.com/cosmos/cosmos-sdk/pull/9766) Fix hardcoded ledger signing algorithm on `keys add` command.
 * [\#9720](https://github.com/cosmos/cosmos-sdk/pull/9720) Feegrant grant cli granter now accepts key name as well as address in general and accepts only address in --generate-only mode
 * [\#9651](https://github.com/cosmos/cosmos-sdk/pull/9651) Change inconsistent limit of `0` to `MaxUint64` on InfiniteGasMeter and add GasRemaining func to GasMeter.
 * [\#9639](https://github.com/cosmos/cosmos-sdk/pull/9639) Check store keys length before accessing them by making sure that `key` is of length `m+1` (for `key[n:m]`)
