Testing & deployment

First steps

Before running anything else, make sure to:

Install the dependencies by running:

npm install

Compile the contracts by running (this command creates the necessary typechain files for frontend also):

npx hardhat compile

Test

Smart contracts tests can be executed by running:

npx hardhat test test/LandToken.ts
npx hardhat test test/LandMinter.ts
npx hardhat test test/LandStaker.ts

Deploy

Create a file called .env inside the smart-contracts repository. Copy everything from the .env.example to .env. Assign the correct value to each variable.
Choose the network where you want to deploy the contracts: hardhat, localhost, mumbai or polygon. Replace <network name> with one of those and run:

npx hardhat run scripts/deploy.ts --network <network name>

LandMinter Contract Walkthrough (how it works)

This is an upgradeable contract and it can be upgraded after deployment.

Phases

Whitelisted phase

By activating this phase, only whitelisted addresses will be able to mint. To activate the whitelisting phase, the contract owner needs to call toggleOnlyWhitelisted function. -> this function toggles the onlyWhitelisted boolean, which acts as a trigger for phases (true = whitelisted phase, false = public phase) Whitelisted addresses are those whose boolean is set to true inside the whitelisted mapping -> to set their status to true call function setWhitelistStatus passing in an array of addresses and an array booleans. Each index inside the array of addresses correlates to the same index inside of the boolean array so the same function can also be used to remove addresses from the whitelist. For more info, there is more documentation regarding this, and other, functions down below (search for the name of the function).

Public phase

This is the default phase (onlyWhitelisted boolean is false by default). If the whitelisted phase is active, the contract owner only needs to call toggleOnlyWhitelisted once again to deactivate the whitelisted phase and enter into to the public phase.

Minting

FIRST STEP

Before the minting starts, the contract owner needs to pass pre-defined token ids using addPremiumsIds and addNonPremiumIds functions. These functions need to be called for each size separately, meaning that the owner can pass all the ids for one size at a time. The added token ids are stored in _mintablePremiumIds mapping and availableNonPremiumIds mapping, as well as idToSize mapping for premium tokens. Once the token ids have been added using the functions above, the minting can start.

mintPremium

The mintPremium function takes in an id as an argument and mints it to the user for the appropriate price. This function checks if the wanted token id is available by querying _mintablePremiumIds. If it is, it mints the token id, if it's not it reverts.

mintNonPremium

The mintNonPremium function takes size as an argument and mints a token with a semi-random token id to the user. This function creates a random index and takes the token id located at that index from the appropriate array of token ids. It then removes that token id from the array.

acquireWithToken

The acquireWithToken function is used when users want to mint for a discount using partnered tokens and mints a premium Land to the user. By default, this function does not work and will work only if any ERC721 token addresses are added using addTokenDiscount function.

Additional contract functionality

airdrop

The airdrop function can be used by the contract owner to mint premium token ids for only gas fee. It works the same as mintPremium function, except it's free, and can only be called by the contract owner.

withdraw

The withdraw function can be used by the contract owner to withdraw all the funds inside the LandMinter smart contract and transfer them to shareholders. Currently, this function transfers 50% of the funds to the space address and the other 50% to the feeRecipient.

renameLand

The renameLand function can be used to rename a token. Renaming a token is free the first time, and requires the user to pay the renameFee on any additional calls. The function itself only emits an event TokenRenamed which will be used by the backend to actually rename the token.

_transferFee

The _transferFee function automatically transfers fee to the feeRecipient address, when any of the payable functions are called.

calculatePrice

The calculatePrice function calculates the price based on the given size, and base parcel price (base price can be premium or regular). It multiplies the base price with the number of parcels that one Land NFT consists of (S = 1, M = 4, ..., D = 600) and also increases the price based on the size premium. The size premiums are premiums that are charged for larger parcel sizes (M size has a 10% premium, L size has a 15%, and the premium goes up to 30% for a district). Both size premiums and land sizes are passed when initializing the contract, and can be additionally changed using appropriate setter functions.

checkRegularLandAvailability

The checkRegularLandAvailability function returns all available non-premium token ids of a certain size, which is passed as an argument. It can be used by the front end to disable the minting button if there aren't any tokens available.

Land (NFT) Contract Walkthrough

This is the actual Land NFT token contract. It has access controls based on a given role.

mint

The mint functions requires the caller of the function to have a MINTER_ROLE. If the caller has that role, this function mints a _tokenId to the given _to address.

toggleRevealed

The toggleRevealed function toggles the revealed boolean. Can only be called by the LAND_MANAGER role. The revealed boolean controls which tokenURI is shown when calling the tokenURI function (it can either be unrevealedURI or the normal art uri which consists of _baseURI/{tokenId})

tokensOfOwner(address _owner)

Returns an array of tokenIDs owned by the _owner wallet.

Necessary for the frontend to display all the user-owned Land tokens.

LandStaker Contract Walkthrough

LandStaker is an upgradeable contract with staking and unstaking functionalities.

stakeLand(uint256 _tokenId)

Stakes a Land by requiring the user to transfer the Land with the passed tokenId to this contract. If the transfer is successful (the user needs to approve the transaction), the contract updates it's several mappings:

staked which shows if a certain tokenID is staked
staker which shows the wallet address of the staked tokenID
stakedAmount which shows the amount of Land staked by a certain wallet address
stakerToTokenIds which shows an array of tokenIDs staked by a certain wallet address
_stakedTokenToIndex this is a private mapping which just stores the index of the staked tokenIDs inside stakerToTokenIds mapping (used for the _removeFromMapping private function)

Lastly, this function emits an event Staked which is required for the backend to calculate the EXP correctly.

unstakeLand(uint256 _tokenId)

Unstakes a Land by transfering the passed tokenID back to the staker. Also updates the several mappings named above.

Emits an event Unstaked which is required for the backend to calculate the EXP correctly.

getStakedTokens(address _staker)

Returns an array of tokenIDs staked by the _staker.

Necessary, for the frontend to display the staked tokenIDs of the user's wallet.
