+# 2023-08-11 - Avalanche Root Gauge Factory V2
+
+Deployment of the `AvalancheRootGaugeFactory`, for stakeless gauges that bridge funds to their Avalanche counterparts.
+This version uses a Layer Zero Omni Fungible Token as the BAL bridge, which is currently used in the Avalanche network.
+Replaces [Avalanche root gauge V1](../deprecated/20230529-avalanche-root-gauge-factory/) which used anySwap wrappers to bridge BAL.
