II. Set values
- User address:
USER A: 0x5B38Da6a701c568545dCfcB03FcB875f56beddC4 (Token owner and deployer)
USER B: 0xAb8483F64d9C6d1EcF9b849Ae677dD3315835cb2
USER C: 0xCA35b7d915458EF540aDe6068dFe2F44E8fa733c
- Contract address:
TOKEN ADDRESS: 0xd9145CCE52D386f254917e481eB44e9943F39138
NFT ADDRESS: 0xd8b934580fcE35a11B58C6D73aDeE468a2833fa8
MARKETPLACE ADDRESS: 0xf8e81D47203A594245E36C48e151709F0C19fBe8
- STEP 1: USER A transfer 1000000 token to USER B
- STEP 2: USER A transfer NFT ID 100 to USER C
III. Make a transaction
Let's say USER B wants to buy USER C's NFT ID 100 for 10000 TOKEN and MARKETPLACE will take 20% of the transaction fee. Here are the steps you do it:
- STEP 1: Allow MARKETPLACE ADDRESS to transfer any NFT owned by USER C:
(NOTE: call function from address C)
- STEP 2: Allow MARKETPLACE ADDRESS to transfer 20000 TOKEN from USER B to any address
(NOTE: call function from address B)
- STEP 3: Make a swap from USER B
USER B is now the owner of NFT ID 100
Balance of USER C
Balance of USER B
Balance of USER A
