NEARYou Demo

About NEARYou

NEARYou allows NEAR wallet user(sender) to create link for giving their NFT(Non-Fungible-Token). Their friends(receiver) can claim NFT through the link. NEARYou contract stores sender's NFT's token_id(NFT id) and NEAR for activaing new account to send NFT when receiver requests claim.

How NEARYou Demo Works

Sender, who has NFT:

• Login with NEAR web wallet.
• Choose NFT that they want to send in "My NFTs" section.
• Click "Approve" button to give authority to NEARYou contract. (This might take some time to NEAR protocol reflects the change. After a moment, the button will change to "Drop" automatically.)
• Cilck "Drop" button to get link for dropping NFT.
• Send copied link to receiver.

Receiver, who has NEAR wallet account:

• Click the link that sender gave you.
• Paste the link in the box and click claim button.
• Get the NFT.

Receiver, who doesn’t have NEAR wallet account:

• Click the link that sender gave you.
• Make new NEAR wallet account.
• Get the NFT.

• drop.js : manage making linkdrop and claim NFT.

drop.js

drop.js has functions that calls NEARYou contract's core function. drop.js has createNFTdrop() , approveUser() and getContract() function which calls NEARYou contract's send() , nft_approve() .

createNFTdrop()

async function fundDropNft(nft_id) {
    const newKeyPair = getNewKeyPair();
    const public_key = (newKeyPair.public_key = newKeyPair.publicKey
      .toString()
      .replace("ed25519:", ""));

    downloadKeyFile(public_key, newKeyPair);

    newKeyPair.nft_id = nft_id;
    newKeyPair.ts = Date.now();
    await addDrop(newKeyPair);

    const { contract } = window;
    try {
      const amount = toNear(minimumGasFee);
      await contract.send(
        { public_key: public_key, nft_id: nft_id },
        BOATLOAD_OF_GAS,
        amount
      );
    } catch (e) {
      console.warn(e);
    }
  }

• createNFTdrop() creates newKeyPair .
• createNFTdrop() calls NEARYou's send() and passes public key and nft_id .

approveUser()

async function approveUser(nft_id) {
    const account = (window.account = window.walletConnection.account());
    const nftContract = await new nearApi.Contract(account, nftContractName, {
      viewMethods: ["get_key_balance"],
      changeMethods: ["nft_approve"],
      sender: window.currentUser.accountId,
    });

    try {
      const amount = toNear(minimumGasFee);
      const result = await nftContract.nft_approve(
        { token_id: nft_id, account_id: contractName },
        BOATLOAD_OF_GAS,
        amount
      );
      console.log("result: ", result);
    } catch (e) {
      console.warn(e);
    }
  }

• approveUser() get current login account and nft contract.
• approveUser() calls nft contract's nft_approve() to give authority to the NEARYou contract.
