 # Governance Proposals
 
+## GrantProviderPrivilegeProposal
+
+Oracle provider privileges can be granted to your account through a `GrantBandOraclePrivilegeProposal`. After the governance proposal is passed, you will be able to relay price feeds using your provider.
+
+
+```protobuf
+// Grant Privileges
+message GrantProviderPrivilegeProposal {
+  option (amino.name) = "oracle/GrantProviderPrivilegeProposal";
+  option (gogoproto.equal) = false;
+  option (gogoproto.goproto_getters) = false;
+
+  option (cosmos_proto.implements_interface) = "cosmos.gov.v1beta1.Content";
+
+  string title = 1;
+  string description = 2;
+  string provider = 3;
+  repeated string relayers = 4;
+}
+```
+
+You can submit your proposal according to the example: 
+
+```bash
+injectived tx oracle grant-provider-privilege-proposal YOUR_PROVIDER \
+  YOUR_ADDRESS_HERE \
+  --title="TITLE OF THE PROPOSAL" \
+  --description="Registering PROVIDER as an oracle provider" \
+  --chain-id=injective-888 \
+  --from=local_key \
+  --node=https://testnet.sentry.tm.injective.network:443 \
+  --gas-prices=160000000inj \
+  --gas=20000000 \
+  --deposit="40000000000000000000inj"
+```
+
+
+To successfully pass the proposal for **testnet**, `YOUR_DEPOSIT` should be slightly less than `min_deposit` 
+value (for example, `40000000000000000000inj`). After that you should contact the Injective dev team. Dev team will 
+top up your deposit to `min_deposit` and vote for your proposal.
+
+## RevokeProviderPrivilegeProposal
+
+Oracle provider privileges can be revoked from your account through a `RevokeProviderPrivilegeProposal`. 
+
+```protobuf
+// Revoke Privileges
+message RevokeProviderPrivilegeProposal {
+  option (amino.name) = "oracle/RevokeProviderPrivilegeProposal";
+  option (gogoproto.equal) = false;
+  option (gogoproto.goproto_getters) = false;
+
+  option (cosmos_proto.implements_interface) = "cosmos.gov.v1beta1.Content";
+
+  string title = 1;
+  string description = 2;
+  string provider = 3;
+  repeated string relayers = 5;
+}
+```
+
 ## GrantBandOraclePrivilegeProposal
 
 Band Oracle privileges can be granted to Relayer accounts of Band provider through a `GrantBandOraclePrivilegeProposal`.
