+## Karura token transfer
+
+To get started, you need to open the hrmr channel.
+Next, we need to register our asset in Karura.
+
+assetRegistry -> registerForeignAsset(location, metadata)
+location:
+ V0(X2(Parent, Parachain(PARA_ID)))
+metadata:
+ name OPL
+ symbol OPL
+ decimals 15
+minimalBalance 1
+
+Next, we can send tokens of our chain:
+polkadotXcm -> reserveTransferAssets
+dest:
+ V0(X2(Parent, Parachain(KARURA_PARA_ID)))
+beneficiary:
+ X1(AccountId(Any, ACCOUNT))
+assets:
+ V1(Concrete(0,Here), Fungible(AMOUNT))
+feeAssetItem:
+ 0
+weightLimit:
+ Limit
+
+
+The result will be displayed in ChainState
+tokens -> accounts
