+
+## Overview
+
+This governance proposal will whitelist the Chainlink relayer contracts required to support the cCOP. The ChainlinkRelayer will transmit rate feed data from a Chainlink price feed or an aggregation of multiple Chainlink price feeds to the SortedOracles contract.
+
+The rate feeds involved are COP/USD and CELO/COP, both of which already have relayer contracts deployed. Details of the rate feeds and corresponding relayer contracts are provided in the table below:
+
+| RateFeed        | RateFeedId                                 | Relayer Contract                                                                                                                  |

+
+## Proposed Changes
+
+1. **Add CELOCOP relayer as oracle**
+
+    - Destination: SortedOracles.addOracle
+    - Data: `0x32ABF1cBdFdcD56790f427694be2658d4B1A83bC`, `0x5926F76D43Ce2D778880226b3C4e7156C8Ece99e`
+    - Value: 0
+
+2. **Set token report expiry for CELOCOP**
+
+    - Destination: SortedOracles.tokenReportExpirySeconds
+    - Data: `0x32ABF1cBdFdcD56790f427694be2658d4B1A83bC`, 360
+    - Value: 0
+
+3. **Add COPUSD relayer as oracle**
+
+    - Destination: SortedOracles.addOracle
+    - Data: `0x0196D1F4FdA21fA442e53EaF18Bf31282F6139F1`, `0x783F947126Adb7646c2A459B867f5B526D2E6603`
+    - Value: 0
+
+4. **Set token report expiry for COPUSD**
+
+    - Destination: SortedOracles.tokenReportExpirySeconds
+    - Data: `0x0196D1F4FdA21fA442e53EaF18Bf31282F6139F1`, 360
+    - Value: 0
+
+5. **Set equivalent token for CELOPHP ratefeedId**
+
+    - Destination: SortedOracles.setEquivalentToken
+    - Data: `0x8A567e2aE79CA692Bd748aB832081C45de4041eA`, `0x32ABF1cBdFdcD56790f427694be2658d4B1A83bC`
+    - Value: 0
+
+## Verification
+
+Check the [forum post](https://forum.celo.org/t/launch-of-ccop-colombia-s-first-decentralized-stablecoin/9211) for a detailed description of verification steps.
+
+## Risks
+
+The data relayed by the ChainlinkRelayer contract is only as secure as the Chainlink price feeds it relies on. If the Chainlink price feeds are compromised, the data relayed by the ChainlinkRelayer contract could be manipulated. This could lead to the SortedOracles contract reporting incorrect rate feeds to the rest of the protocol.
+
+This risk is present with all Oracle solution and is not specific to the Chainlink price feeds. In order to mitigate this risk, the Mento Protocol has implemented onchain circuit breakers that automatically pause the protocol if the reported data is outside of a predefined threshold. As well as our onchain trading limits, which limit the trading bandwidth.
