+title: "Aave Liquidity Committee Funding Phase IV"

+
+## Simple Summary
+
+Upon implementation, this AIP will make available 950,000 GHO to the Aave Liquidity Committee (ALC).
+
+## Motivation
+
+Phase IV of the ALC focuses on sustaining and improving GHO liquidity across the Ethereum and Arbitrum networks, while also encouraging broader adoption of GHO through various integrations with other protocols.
+
+In the near future, we expect GHO to be listed on InstadApp, with several curated vaults providing additional utility and yield opportunities for GHO.
+
+GHO is also expected to feature in the upcoming Royco launch, aimed at driving flows into several yield strategies across Ethereum and Arbitrum.
+
+We anticipate achieving the first perpetual market integration for GHO with a strataGHO listing on Synthetix on Arbitrum.
+
+Each integration is expected to provide a use case that strengthens GHO's on-chain liquidity.
+
+The table below presents the performance metrics for the ALC.
+

+Achieving 50M of DEX liquidity on Ethereum across various integrations remains a key focus. Whilst we are yet to acheive this target, we are currently very well positioned for current market conditions.
