Multi-Token-DAO-Smart-Contract

What is DAO ?

DAO stands for Decentralized Autonomous Organization an open-source Blockchain protocol governed by a set of rules, created by its members, which automatically execute certain actions without the need for intermediaries. DAO is a community-led entity with no central authority. It is fully autonomous and transparent.

In MultiToken DAO either you can vote with Token or NFT.

There are five Contract.

• Nappy Token (ERC20Token)
• NappyNFT (ERC721Token)
• TimeLock
• Governance
• Treasury

Nappy Token

• Token Name: Nappy Token
• Token Symbol: NPY
• Nappy Token will use to mint token and transfer to voter for use in voting.
• First owner will mint the token. There is no fixed supply to mint the token.
• This contract will also use for delegate the tokens. User will have to call delegate() function for voting power.
• Voting power is depend on decimal of Token.

NappyNFT

• Token Name: NappyNFT
• NFT Symbol: NPY
• NappyNFt will use to mint NFT and transfer to voter for use in voting.
• First owner will mint the NFT. There is no fixed supply to mint the NFT.
• This contract will also use for delegate the NFT. User will have to call delegate() function for voting power.
• Voting power of one NFT is one.

TimeLock

• This contract will set as owner of the Treasury contract.

• It will decide how many block's to wait to execute proposal.

Governance

• This contract will create the proposal and vote for the same.
• In this contact user can create the proposal, vote, cancel.
• There are several stages for proposal.

Stages

Sr No	Stages
0	Pending
1	Active
2	Cancelled
3	Defeated
4	Succeeded
5	Queued
6	Expired
7	Executed

• First of all we will deploy the contract. We will get contract address of all deploy contract.

  npx hardhat run scripts/deploy.js --network mumbai

• Nappy Token : 0xb1E2d34eE670F4B91C8015547D4E1F1f89a61f92

• NappyNFT : 0x0c85214E55324d86395A8148Fe4FB395f185Ae02

• TimeLock : 0xf43d582A34BfD50395CB8A96150E54a89D507BE3

• Governance : 0x4dDe5bc62a29DE1e7aE84902E8D0ddA7Fb0D03fE

• Treasury : 0x7dfBd09387E7b903edb40db98515bAF8c3158722

• After this we will call createProposal scripts.

  npx hardhat run scripts/createProposal.js --network mumbai

• After this function we will get proposal Id.

• Proposal Id : 63443021524830328481685862710718740376614608430634741687791276264061360147468

• Now we will check state of the DAO.

• Before check the state we have to wait for to mine 20 Blocks to mine.

  npx hardhat run scripts/checkState.js --network mumbai

• It will give state 1 means our proposal is Active.

• Now everyone will vote using castVote function.

• Some will vote with NFT & some will vote with Tokens.

  npx hardhat run scripts/voteOnProposal.js --network mumbai

• Now we will check state of the DAO.

  npx hardhat run scripts/state.js --network mumbai

• It will give state 4 means our proposal is Succeeded.

• The voting is Succeeded.

• Now we will call the queue function our proposal is pass.

  npx hardhat run scripts/queueProposal.js --network mumbai

• It will give state 5 means our proposal is Succeeded.

• Now our proposal is in Queue.

• Now we will Execute the proposal.

  npx hardhat run scripts/executeProposal.js --network mumbai

• It will give state 7 means our proposal is Executed.

• Our proposal is successfully executed.

Get item

Treasury

• You have to send some ether or any ERC20Token or ERC721 to Treasury.
• This contract will store the ether. Anyone can send the ether to this contract.
• Only owner(timelock) can withdraw the funds.
• It transfer ownership to TimeLock Contract using transferOwnership function.
