🚀 Web3.0 Simplified Payment Gateway

Overview

CoreDaoVIP bridges the gap between traditional web developers and blockchain by providing simple APIs that allow:

• Checking CoreDaoVIP token balance
• Transferring tokens between accounts
• Splitting payments to brokers, associates, or affiliates
• Approving spenders and managing allowances
• Verifying user eligibility for services based on token holdings

These facilities make it easier for developers to integrate crypto-based payments into shopping websites, movie booking platforms, and service-based applications without needing deep blockchain knowledge.

CoreDaoVIP API (JavaScript SDK)

The full API provided by CoreDaoVIP is as follows:

// coredaovip.js
// Simple SDK for CoreDaoVip Token (ERC20)

// Import ethers.js (assumes it's already available in project)
const { ethers } = window;

// CoreDaoVip contract
const COREDAOVIP_ADDRESS = "0x3c18c0be00c516d5c08d94a118fb185b99afa601"; 
const ERC20_ABI = [
  "function decimals() view returns (uint8)",
  "function balanceOf(address owner) view returns (uint256)",
  "function transfer(address to, uint256 value) returns (bool)",
  "function approve(address spender, uint256 value) returns (bool)",
  "function allowance(address owner, address spender) view returns (uint256)"
];

class CoreDaoVipSDK {
  constructor() {
    this.provider = null;
    this.signer = null;
    this.account = null;
  }

  // 🔹 Connect MetaMask
  async connectWallet() {
    if (typeof window.ethereum === "undefined") {
      throw new Error("MetaMask not installed!");
    }
    await ethereum.request({ method: "eth_requestAccounts" });
    this.provider = new ethers.providers.Web3Provider(window.ethereum);
    this.signer = this.provider.getSigner();
    this.account = await this.signer.getAddress();
    return this.account;
  }

  // 🔹 Get contract instance
  getContract(providerOrSigner = this.provider) {
    return new ethers.Contract(COREDAOVIP_ADDRESS, ERC20_ABI, providerOrSigner);
  }

  // 🔹 Get balance
  async getBalance(account = this.account) {
    if (!account) throw new Error("Wallet not connected");
    const contract = this.getContract(this.provider);
    const decimals = await contract.decimals();
    const rawBalance = await contract.balanceOf(account);
    return ethers.utils.formatUnits(rawBalance, decimals);
  }

  // 🔹 Check service eligibility
  async isEligible(minRequired = 1, account = this.account) {
    const balance = await this.getBalance(account);
    return parseFloat(balance) >= minRequired;
  }

  // 🔹 Transfer tokens
  async transfer(to, amount) {
    if (!this.signer) throw new Error("Wallet not connected");
    const contract = this.getContract(this.signer);
    const decimals = await contract.decimals();
    const value = ethers.utils.parseUnits(amount.toString(), decimals);
    const tx = await contract.transfer(to, value);
    await tx.wait();
    return tx.hash;
  }

  // 🔹 Approve spender
  async approve(spender, amount) {
    if (!this.signer) throw new Error("Wallet not connected");
    const contract = this.getContract(this.signer);
    const decimals = await contract.decimals();
    const value = ethers.utils.parseUnits(amount.toString(), decimals);
    const tx = await contract.approve(spender, value);
    await tx.wait();
    return tx.hash;
  }

  // 🔹 Check allowance
  async allowance(owner = this.account, spender) {
    const contract = this.getContract(this.provider);
    const allowance = await contract.allowance(owner, spender);
    return allowance.toString();
  }
}

// Export as singleton
window.CoreDaoVipSDK = new CoreDaoVipSDK();

Conclusion

With this API, CoreDaoVIP makes blockchain-based payment integration straightforward and educational, allowing developers to demonstrate and adopt tokenomics use cases with ease.
