+title: "Activate Freezing Steward on v3 missing networks"
+author: "BGD Labs @bgdlabs"
+discussions: "https://governance.aave.com/t/bgd-technical-maintenance-proposals/15274"
+---
+
+## Summary
+
+Activates the `FreezingSteward` smart contract across all the networks of the protocol, which allows the emergency admin to freeze reserves, as expected.
+
+Currently, there are freezing stewards live for all the networks except Avalanche, Metis, and Base, and this proposal synchronizes the missing ones.
+
+## Motivation
+
+This is a follow-up to [AIP-319](https://app.aave.com/governance/proposal/319/) where on some networks (Avalanche, Metis, and Base) the proposal wasn’t executed. We now resubmit the proposal as an operational update to maintain security and consistency across Aave V3.
+
+## Specification
+
+Adds the `FreezingSteward` contract as `RISK_ADMIN` on the canonical Aave V3 deployments on the following networks:
+- Avalanche
+- Metis
+- Base
+
+The `FreezingSteward` is identical to the one currently deployed on [Ethereum](https://etherscan.io/address/0x2eE68ACb6A1319de1b49DC139894644E424fefD6#code), [Polygon](https://polygonscan.com/address/0xa7b40ed4dfAC9255EA9Dd218A3874f380D9FbBEB), [Optimism](https://optimistic.etherscan.io/address/0x3829943c53F2d00e20B58475aF19716724bF90Ba), [Arbitrum](https://arbiscan.io/address/0xe59470b3be3293534603487e00a44c72f2cd466d) and only allows for entities holding `EMERGENCY_ADMIN` role on `ACLManager` to freeze reserves.
