338## Karura token transfer
339
340To get started, you need to open the hrmr channel.
341Next, we need to register our asset in Karura.
342
343assetRegistry -> registerForeignAsset(location, metadata)
344location:
345	V0(X2(Parent, Parachain(PARA_ID))) 
346metadata:
347	name         OPL
348	symbol       OPL
349	decimals     15
350minimalBalance	 1
351
352Next, we can send tokens of our chain:
353polkadotXcm -> reserveTransferAssets
354dest:
355	V0(X2(Parent, Parachain(KARURA_PARA_ID))) 
356beneficiary:
357	X1(AccountId(Any, ACCOUNT))
358assets:
359	V1(Concrete(0,Here), Fungible(AMOUNT))
360feeAssetItem: 
361	0	
362weightLimit:
363	Limit
364	
365
366The result will be displayed in ChainState   
367tokens -> accounts
