How to call Contract from other contract using Interface

I made this interface form my first contract let say Contract1 and now I am trying to call this contract using other contract let say Contract2 by

IContract1 Contract1 = IContract1(TUVXi6oCYEy3mya2UxBBMBMc1A4G5Hqdpk);
TRC721 Contract1 = TRC721(TUVXi6oCYEy3mya2UxBBMBMc1A4G5Hqdpk);

I also converted them to hex using

` ``
tronWeb.address.toHex(“TVm22VuHmhxAuxN9f1LfpmrJTWS8aAYG9R”)
‘41d9145cce52d386f254917e481eb44e9943f39138’

maybe it need to be storage or memory :thinking:

But I mean in ETH solidity this works fine

seems like address are weird, normally we have address start with 0x

Damn I found the answer hope it help full to others, so address should be start from 0x and I don’t how to create such address from TVm22VuHmhxAuxN9f1LfpmrJTWS8aAYG9R to 0x address

but if you are using IDE and call ownerOf function it returns 0x so first I transfer the nft to the contract and check the ownerOf for that tokenId and volia got the address
