Important Notes:

• In order to run my tests, open a terminal and start ganache-cli, then on another terminal make sure that you are in capstone\blockchain-capstone\eth-contracts, then type truffle test.

• In case you want to deploy my contract on the Rinkeby TestNetwork, make sure to put your Metamask mnemonic and infura key in the truffle-config.js file.

• In order to deploy my contracts on the Rinkeby Test Network, I used truffle migrate —reset —network rinkeby.

Tokens:

• After deploying the contracts on the Rinkeby TestNetwork, I used MyEtherWallet to mint 10 tokens, to mint tokens, I used the ABI and contract address of SolnSquareVerifier Contract that were listed above, I made sure to connect my MetaMask account with MyEtherWallet and OpenSea. Below are the transaction hashes and the links for the 10 tokens:

• Original Owner of the tokens: 0xB8DDbc2D6635dE3d2da292A9a4D59cb97D8458f6

• Original Owner Name on OpenSea: mira

• First Token:
  Transaction Hash: 0xf87e79a1ea04859e763b02332134af6f628aa79e7ee68d7f8e13e82ef7dba337
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/1/

• Second Token:

  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/3/

• Fourth Token:
  Transaction Hash: 0xb5f728a8b356fa513be8e611d98b4ebd9e56b1c150c3aa2492c950f71d790d91
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/4/

• Fifth Token:
  Transaction Hash: 0xf47ebdb4c7bc435126df1f7200d3af4d88de6ea608657e1c06749fe93e51f708
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/5/

• Sixth Token:
  Transaction Hash: 0xba298de69935e7f77751b202793c1a38de933f5f9e6381316e646c3d4253df1b
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/6/

• Seventh Token:
  Transaction Hash: 0xd85b974aa79c9def74de6ba8b7fb4b59fb25e51a66ea0dcf3cd5cdcf77ac384b
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/7/

• Eighth Token:
  Transaction Hash: 0x7bbc72a0e6f75cb8fe7f78de075a8c9c7249a05bf9b9506a6d0d311d87ba282d
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/8/

• Nineth Token:
  Transaction Hash: 0x49a4b3b1d959e904ea917e09b8165d762e3f8c69dd593dcb7634bf1ab0c7663a
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/9/

• Tenth Token:
  Transaction Hash: 0x3fb7a7552b316e014eec4106e3afc6998ba707ea321587642a44b94279eea3f5
  Link: https://testnets.opensea.io/assets/0xd66312317870a4861eb86a7dce959906cedb9b95/10/

• After that, I put 5 tokens on sale; tokens with IDs 1, 3, 5, 7, 10 as shown in the screenshots below.
  
  
  
  

• I then purchased the 5 tokens as required:
  Buyer Address: 0x72F081DDA134C5D2Ed227Cb15c69F3AfcfB7c85F
  Buyer Name on OpenSea: mira2

Shown below is a screenshot of putting token with ID: 1 on sale and buying it afterwards (same procedure was followed to put the rest of the tokens on sale and to buy them):



mira putting token with the ID of 1 on sale (the 3 screenshots below): (mira is the owner in this stage)












mira2 purchasing token with the ID of 1 (the 3 screenshots below): (mira2 is now the owner)

• Below are the transaction hashes of the purchase of the 5 tokens:
  Token 1 Purchase Transaction Hash: 0x6fa77c53bcda681e45e620e008125b4d46b62c4de3f06e1df786384fec9c7d6b
  Token 3 Purchase Transaction Hash: 0xaed064c785c2702bf8b23cd3c5c47b845d2bbdeab6ee23f7937b7ddc4a9131a1
  Token 5 Purchase Transaction Hash: 0xf69ef969102443ff25c797589093e39792efe6b2b3e02fc3394f42e5da3ace5a
  Token 7 Purchase Transaction Hash: 0x3e684d4bafedcaa32917478621df70323c3725c73631d743ca53256dcce00094
  Token 10 Purchase Transaction Hash: 0xe6adb915a27b75817eeee65ca9456a75fd00bbf57004299916dbf97c10fc712e

Now, as can be seen, mira owns 5 tokens, and mira2 owns the rest (the 5 tokens that she purchased from mira):

• mira:
  
  
  
  
  
  
  
  
• mira2:
