Etherlink: Scenario 2 - ERC-721 (token)

Context

The live-testing-protocols external repository answers the following task of the End-to-end, real world scenarios project:

Scenario 2: ERC-721 (token)

• Basic scenario for using the ERC-721 token: NFT (Non-Fungible Token).

The code for the scenario can be found in BasicNFT.sol.

Actions:

1. Owner can create a token
   • The creation event is emitted
   • The owner balance is increased
2. Owner can transfer a token
   • The transfer event is emitted
   • The receiver balance is increased
   • The sender balance is decreased

The code for the actions can be found in BasicNFT.ts.

As files are kept on a separate repository, we are not putting too many efforts on reviewing code quality. Reviews should focus more on whether the scenario covers interactions between ERC-721 standard and Etherlink.

Manually testing the MR

Follow these instructions specialized with the ERC-721 test.

• Local: npx hardhat test test/ERC721/BasicNFT.ts.
• Ghostnet: npx hardhat test --network etherlink test/ERC721/BasicNFT.ts.

The test should go through, even if the interaction actually fails because of some issues in Etherlink, not the scenario. (Fixing Etherlink would be the purpose of the next task.)
