Spark 发行器 SDK

Spark是最快,最便宜,而且最UX友好的方式,在Bitcoin上建立金融应用程序和推出本土资产. 比特币(Bitcoin L2)让开发者以近乎零的成本立即移动比特币和比特币本土资产(包括稳定币),同时保持与比特币基础设施的完全连接.

快速启动

初始化发行人钱包

import { IssuerSparkWallet } from "@buildonspark/issuer-sdk";

// Create a new issuer wallet (generates a new mnemonic)
const { wallet, mnemonic } = await IssuerSparkWallet.create({
  options: {
    network: "MAINNET", // or "REGTEST" for testing
  },
});

// Or initialize with an existing mnemonic
const wallet = await IssuerSparkWallet.initialize({
  mnemonicOrSeed: "your twelve word mnemonic phrase here ...",
  options: {
    network: "MAINNET",
  },
});

创建一个托肯

const token = await wallet.createToken({
  tokenName: "My Token",
  tokenTicker: "MTK",
  decimals: 8,
  maxSupply: 1000000n,
  isFreezable: true,
});

console.log(`Token created: ${token.tokenIdentifier}`);

薄荷图案

// Mint tokens to your own wallet
const mintResult = await wallet.mintTokens({
  tokenIdentifier: "spark1...",
  tokenAmount: 10000n,
});

// To distribute tokens to others, mint first then transfer
await wallet.mintTokens({
  tokenIdentifier: "spark1...",
  tokenAmount: 5000n,
});

await wallet.transferTokens({
  tokenIdentifier: "spark1...",
  receiverSparkAddress: "sp1q...",
  tokenAmount: 5000n,
});

检查发行人托肯余额

// Get balance for all tokens you've issued
const balances = await wallet.getIssuerTokenBalances();
for (const [tokenId, info] of balances) {
  console.log(`${info.tokenMetadata.tokenName}: ${info.balance}`);
}

冻结/解冻托肯斯

// Freeze tokens at a Spark address (requires isFreezable: true during creation)
await wallet.freezeTokens({
  tokenIdentifier: "spark1...",
  sparkAddress: "sp1q...",
});

// Unfreeze tokens at a Spark address
await wallet.unfreezeTokens({
  tokenIdentifier: "spark1...",
  sparkAddress: "sp1q...",
});

烧掉托肯斯

const burnResult = await wallet.burnTokens({
  tokenIdentifier: "spark1...",
  tokenAmount: 1000n,
});

查询托肯交易

const transactions = await wallet.getTokenTransactions({
  tokenIdentifier: "spark1...",
  limit: 50,
});

for (const tx of transactions) {
  console.log(`TX: ${tx.id}, Amount: ${tx.amount}`);
}
