A dapp for staking NFTs.

• NFTReward (nft_reward_gold, nft_reward_silver, nft_reward_platinum)
• NFTStaker (nft_staker)

Tools and Technologies Used

• nft:
  • IPFS, NFTs, Python
• contract:
  • Smart contracts (ERC20, IERC20, ERC721Enumerable, Ownable, ERC20Burnable, IERC721Receiver)
  • Hardhat, Ethers.js, Solidity, OpenZeppelin, Remix IDE, Ethereum, EVM (Ethereum Virtual Machine), Blockchain, Etherscan, JavaScript, Mocha Testcases, Solidity code coverage
• dapp:
  • React.js, Web3.js, Nginx, Metamask wallet
• Docker and Containers
• Ethernal dashboard - EVM compatible private blockchain network explorer.
• GitHub actions

How To Run?

• Upload NFTs to IPFS
• Deploy smart contracts to the blockchain
• Run the dapp

Workflow

1. Token [name, symbol, maxSupply, totalSupply, balanceOf (hash_wallet_accounts)]
2. NFTMinter [name, symbol, owner, baseURI, maxSupply, totalSupply, cost, customPaymentCurrencies, getCustomPaymentCurrencies]
3. NFTMinter [mint - with native token for user (not for owner)]
4. Token [balanceOf (user), approve (all balance tokens of user as an allowance to spend by NFTMinter smart contract), allowance], NFTMinter [mint - with custom token for user (not for owner)]
5. NFTMinter [totalSupply, balanceOf, walletOfOwner, tokenURI, ownerOf]
6. Token [balanceOf (NFTMinter smart contract and NFTMinter smart contract owner account)], NFTMinter [withdraw - native token balance AND custom token balance]
7. NFTReward [name, symbol, owner, maxSupply, totalSupply, balanceOf (owner account), controllers (NFTStaker smart contract)]
8. NFTStaker [owner, getVaults, vaults, totalStaked]
9. NFTMinter [setApprovalForAll (set NFTStaker smart contract as operator to handle all NFTs of a particular user account), isApprovedForAll]
10. NFTStaker [stake, totalStaked, totalStakesOf, stakedTokensOf, stakes]
11. NFTStaker [fetchReward (after creating a dummy transaction/block in the blockchain - like minting Token for a user), claim], NFTReward [balanceOf]
12. NFTStaker [unstake, totalStaked, totalStakesOf, stakedTokensOf, stakes], NFTMinter [ownerOf, walletOfOwner]
