+## About the `ERC721NFTs` contract
+
+The `ERC721NFTs` contract is a harcoded contract at address `0x1074030000000000000000000000000000000000`. Every <!-- TODO Confirm --> L1 NFT owned by the chain can be accessed through it. In this example we will show you how to use it by taking `transferFrom`  as an example.
+
+## Example Code
+
+1. ERC721 uses `tokenID` for almost all interactions with it. So we first convert our `NFTID` to a `tokenID`:
+
+```solidity
+uint256 tokenID = uint256(NFTID.unwrap(nftID));
+```
+
+:::info Token ID to NFT ID
+
+To go the other way around and convert a Token ID to an NFT ID, you can use the ISCTypes.asNFTID() function, by either using (`using ISCTypes for uint256;`) it on token ID like `tokenID.asNFTID();` or passing it to function like `ISCTypes.asNFTID(tokenID)`.
+
+:::
+
+2. Transfer the token with ID `tokenID`, by using the `ERC20NFTs` contract, which is exposed in the library as `ISC.nfts`, and calling the standard `transferFrom` function
+
+```solidity
+ISC.nfts.transferFrom(msg.sender, _destination, tokenID);
+```
