I am getting an error on the "import" commands in the XRC721.sol file:

Not sure what steps are to fix this issue.

I have updated the code for the contracts. They would work fine now.

@yash0501 thank you, that solved the problem. We are now up against the same verification issue as we saw with Remix. Give me a few hours to see if I can get more information on this issue from BlocksScan.

@yash0501 BlocksScan pointed me to this tutorial on flattening the dependencies from OpenZeppelin: https://www.xdc.dev/ivan_blocksscan/learn-how-to-flatten-a-smart-contract-and-verify-on-blocksscan-56on

[WalterBlueu]

I don't know if this tool is what you need for Truffle, but it looks like updating the how-to to use a tool like this to flatten the smart contract will get the job done: https://www.npmjs.com/package/truffle-flattener

Okay, I will check it out and try to flatten the smart contract to verify it on blockscan
