## What is a TAC RPC Node?

Access adoption-focused blockchain

A TAC RPC node provides applications with access to blockchain infrastructure specifically designed for mass adoption. TAC removes the complexity that prevents mainstream users from adopting blockchain — confusing wallets, gas fees, seed phrases, and technical barriers. This enables applications to offer blockchain benefits with Web2-level user experience.

### Why adoption matters

Blockchain's potential is limited by poor UX. Average users don't understand gas, private keys, or DeFi. **TAC prioritizes adoption** — gasless transactions, fiat integration, simplified onboarding, and familiar interfaces. This brings blockchain to billions, not just crypto enthusiasts.

**TAC advantages:**

- **User-friendly** — Web2-level UX
- **Gasless options** — no crypto required to start
- **Fiat integration** — buy with credit cards
- **Simple wallets** — email/social login
- **EVM compatible** — familiar development
- **Real-world focus** — business integration

### Removing friction

TAC removes **adoption friction** through account abstraction, meta-transactions, and fiat on-ramps. Users can interact with blockchain without owning crypto, understanding gas, or managing seed phrases. This 'invisible blockchain' approach makes Web3 accessible to everyone.

**How TAC enables adoption:**

1. Users sign up with email/social media
2. No crypto wallet setup required initially
3. Applications sponsor gas fees (gasless UX)
4. Fiat payments converted to crypto automatically
5. Blockchain benefits without blockchain complexity

### Real-world integration

TAC focuses on **real-world use cases** — payments, loyalty programs, ticketing, supply chain, identity — where blockchain provides value but complexity is a barrier. By making blockchain invisible to end users, TAC enables businesses to integrate Web3 without forcing customers to become crypto experts.

This infrastructure powers mainstream blockchain adoption at scale.

## Technical Documentation

Quick start for developers

### Supported RPC Methods

TAC supports all standard Ethereum JSON-RPC methods:

- **eth\_blockNumber** — current block number
- **eth\_getBalance** — TAC balance
- **eth\_call** — execute view functions
- **eth\_sendRawTransaction** — broadcast transactions
- **eth\_getTransactionReceipt** — transaction confirmation
- **eth\_getLogs** — event logs
- **eth\_gasPrice** — current gas price
- **eth\_estimateGas** — gas estimation
- **eth\_subscribe** — WebSocket subscriptions

### Code Examples

💻

#### JavaScript (ethers.js) — TAC Connection:

```
const { ethers } = require('ethers');

const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/tac/YOUR_API_KEY');

// Verify we're on TAC
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 239

// Get TAC balance
const balance = await provider.getBalance('0x...');
console.log('TAC Balance:', ethers.formatEther(balance));

// Deploy user-friendly application
const USER_APP = '0x...';
const appABI = [
  'function createAccountWithEmail(string email) external returns (address)',
  'function sponsorTransaction(address user, bytes txData) external',
  'function purchaseWithFiat(uint256 amount, string paymentMethod) external'
];
const app = new ethers.Contract(USER_APP, appABI, wallet);

// Enable gasless user experience
const userAccount = await app.createAccountWithEmail('user@example.com');
console.log('User account created without crypto knowledge!');
console.log('Blockchain made accessible!');
```

💻

#### Python (web3.py) — TAC Setup:

```
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/tac/YOUR_API_KEY'))

print('Connected to TAC:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 239
print('Latest block:', w3.eth.block_number)

# Low fees for adoption
gas_price = w3.eth.gas_price
print(f'Gas price: {gas_price}')

# Get TAC balance
balance = w3.eth.get_balance('0x...')
print(f'TAC: {balance / 1e18}')
```

💻

#### WebSocket — Monitor TAC Activity:

```
const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/tac/ws/YOUR_API_KEY');

// Monitor blocks
provider.on('block', async (blockNumber) => {
  const block = await provider.getBlock(blockNumber);
  console.log(`TAC block ${blockNumber}: ${block.transactions.length} txs`);
});

// Monitor user onboarding
const ONBOARDING = '0x...';
const filter = {
  address: ONBOARDING,
  topics: [ethers.id('NewUserOnboarded(address,string)')]
};

provider.on(filter, (log) => {
  console.log('New user onboarded to Web3:', log);
  console.log('Mass adoption in action!');
});
```

### TAC Best Practices

- **UX First:** Design for non-crypto users
- **Gasless Transactions:** Sponsor gas for users when possible
- **Fiat Integration:** Support credit card and traditional payments
- **Simple Onboarding:** Email/social login over seed phrases
- **Mobile Optimization:** Design for mobile-first audience
- **Testing:** Test user flows on TAC testnet
