+### Agenda
+
+- Team updates
+- iOS 18 updates! Heads up!!
+- If chainsafe is present, In-Memory Wallet status (https://github.com/zcash/librustzcash/issues/1414) 
+- ZIP 320 statuses towards Sept 20th.

+
+# Team Updates
+
+**Zingo:**
+- librustzcash and Zingo’s fork diverged to they are completing the convergence. They expect to have it by the
+
+**ChainSafe:**
+migrated test to sqlite crate to the zcash client back end to be used with any backend. 
+In Memory wallet passes their full test suite. 
+All of the above works in the wallet.
+Benchmarks with ZecPages seems reasonable. 
+Think they’ll be able to ship on time. 
+There’s a demo wallet front end to dogfood the Web JS sdk
+A blocker is that Zcash transaction creation separation to be able to not store keys in the web app. Mid-October this will become a full blocker to complete the snap 
+
+Status of Partial transaction format (PCZT) for Hardware wallets and FROST:
+- There’s transaction construction steps
+- There’s a proof building step
+- Then the authorization of the PCZT is done
+- The proved PCZT and the authorized PCZT are merged and the transaction is created. 
+
+No progress has been made. Input is being gathered to know how the different wallets will be using PCZT. https://github.com/zcash/zips/issues/693
+
+Chainsafe will share their list of requirements  
+
+Str4d will try to resume the refactoring to achieve this but he was blocked by ZIP-320 work 
+
+### ZIP-320 Retrospective, when is it a good time to do it?
+Str4d: If so there should be 2 different retrospectives one for the engineering side and one for the outreach we wouldn’t want to mix those two.
