+# Client Team Updates
+## EL
+
+* **Nethermind**: 
+ * Shutter
+ * Working on Shutter’s cryptographic implementation
+ * Still no Docker image for the testnet
+* Released 1.25.0 with performance improvements, geth compatible tracers and JSON-RPC improvements (was a preview last week)
+
+
+* **Erigon**: 
+ * We need to test the image for aggressive pruning provided by Somnath
+ * Checked the logs for Nimbus + Erigon missed slots for devnet 3
+ * Could not find a reason why the payloads would be invalid
+ * The sequence of requests for payloads might not be optimal on Nimbus’ side (some type of race condition?)
+ * There might be a bug in the transaction pool for Erigon during block building
+ * Discovered because of a Hive test failure on Ethereum
+ * Somnath is looking into it
+ * Released a new version
+
+
+
+* **Geth**:
+ * Not present
+ * There’s still the issue about the synced state not being considered as the canonical one
+ * Guillaume is looking into implementing full sync with AuRa
+
+
+# Shadow Fork
+
+* We want to shadow fork Chiado to make sure that everything works
+* We need a copy of the deposit contract deployed on Chiado
+ * I.e. just a new proxy that points to the same implementation

+
+# Hive Test
+
+* Fixed the actions that were failing, which were due to misconfiguration in the clients
+* Erigon is still missing 3 tests that should not be failing
+* Building a tool to push hive test logs to Telegram every day
+
+
+
+# Devnet
+
+* Running devnet 3 that started this week
+ * Overall the network is healthier than devnet 2
+* Two issues
+ * Nimbus + Erigon pair, Somnath is looking at it currently
+ * Other Erigon pairs seem to work fine
+ * Blob fuzzing script has issues
