 ### Features
 
+* [\#9776](https://github.com/cosmos/cosmos-sdk/pull/9776) Add flag `staking-bond-denom` to specify the staking bond denomination value when initializing a new chain.
 * [\#9533](https://github.com/cosmos/cosmos-sdk/pull/9533) Added a new gRPC method, `DenomOwners`, in `x/bank` to query for all account holders of a specific denomination.
 * (bank) [\#9618](https://github.com/cosmos/cosmos-sdk/pull/9618) Update bank.Metadata: add URI and URIHash attributes.
 * [\#9750](https://github.com/cosmos/cosmos-sdk/pull/9750) Emit events for tx signature and sequence, so clients can now query txs by signature (`tx.signature='<base64_sig>'`) or by address and sequence combo (`tx.acc_seq='<addr>/<seq>'`).
