生成IOTA钱包地址

• 配置环境:
  • npm init
  • npm install @iota/core @iota/converter
• 生成随机seed(私钥): cat /dev/urandom |tr -dc A-Z9|head -c${1:-81}
• 私钥可以关联多个地址, 执行下面代码, 生成两个钱包地址:

const Iota = require('@iota/core');

const seed =
    'KHSYXDNSEOVFCAERBIPDIXMMXSQKOBPJTAVRGBYXCENMPXOZNHIOKSANOHCTRLGBXBLSINTYIXWZIKMFQ';
const index = 0;
const securityLevel = 3;
const addrCnt = 2;

// Connect to a node
const iota = Iota.composeAPI({
    provider: 'https://nodes.devnet.iota.org:443',
});

// generate two address
iota.getNewAddress(seed, {
    index: index,
    securityLevel: securityLevel,
    total: addrCnt,
})
    .then((address) => {
        console.log('Your address is: ' + address);
    })
    .catch((err) => {
        console.log(err);
    });

// output:
// Your address is: RLSEXCEJSSELIHZ9KUXDQN9SDRNAIDPIELWKHGFTORWL9LDZRMFYMRKNFNLODWEKDPEUKCHSC9CH9VRRX,ZWZQGKTJGENPOVVRJNDRNEWQAMDAHFFY9OUVJEEGLCWZHEYU9DADWRFWFVLRRAKWQZWDVNK9LMWQU9UOW
// 第1个地址的`index = 0`, 第2个地址的`index = 1`;

• 在 获取测试Token网站 获取测试Token
• 在 devnet 通过地址查询获取到的测试Token
• 发送Token测试:

const Iota = require('@iota/core');
const Converter = require('@iota/converter');

// Connect to a node
const iota = Iota.composeAPI({
    provider: 'https://nodes.devnet.iota.org:443',
});

// Define the depth that the node will use for tip selection
const depth = 3;
// Define the minimum weight magnitude for the Devnet
const minimumWeightMagnitude = 9;

// Replace this seed with the one that owns the address you used to receive test tokens
const seed =
    'KHSYXDNSEOVFCAERBIPDIXMMXSQKOBPJTAVRGBYXCENMPXOZNHIOKSANOHCTRLGBXBLSINTYIXWZIKMFQ';

// Create a wrapping function so you can use async/await
const main = async () => {
    // Define an address to which to send IOTA tokens
    const receivingAddress =
        'ZWZQGKTJGENPOVVRJNDRNEWQAMDAHFFY9OUVJEEGLCWZHEYU9DADWRFWFVLRRAKWQZWDVNK9LMWQU9UOW';

    const message = JSON.stringify({"message": "Heng30 tests api"});

    // Convert the message to trytes
    const messageInTrytes = Converter.asciiToTrytes(message);

    // Define an input transaction object
    // that sends 10i to your new address
    const transfers = [
        {
            value: 10,
            address: receivingAddress,
            message: messageInTrytes,
        },
    ];

    console.log('Sending 10i to ' + receivingAddress);

    try {
        // Construct the bundle and sign your input transactions
        const trytes = await iota.prepareTransfers(seed, transfers);
        // Send the transactions to the node
        const response = await iota.sendTrytes(
            trytes,
            depth,
            minimumWeightMagnitude
        );

        console.log('Bundle sent');
        response.map((tx) => console.log(tx));
    } catch (error) {
        console.log(error);
    }
};

main();
