 ## Unreleased
 
+### Features
+
+* [\#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>'`).
+
 ### Improvements
 
 * (baseapp) [\#9578](https://github.com/cosmos/cosmos-sdk/pull/9578) Return `Baseapp`'s `trace` value for logging error stack traces.
