## What is a Telos RPC Node?

Access green, fast blockchain

A Telos RPC node provides applications with access to one of the fastest EVM blockchains, featuring 0.5-second blocks and a unique gas fee model where end users pay nothing. Telos is also carbon-negative, making it the greenest high-performance blockchain — combining speed, cost-efficiency, and environmental sustainability.

### Why Telos is unique

Telos achieves what most blockchains can't: **high performance** (0.5s blocks, 10K TPS), **zero user fees** (subsidized gas), and **carbon-negative operations**. This combination makes Telos ideal for applications needing speed and sustainability without burdening users with gas costs.

**Telos advantages:**

- **0.5s blocks** — fastest EVM blockchain
- **Zero user fees** — gas subsidized for end users
- **Carbon negative** — ESG compliant, greenest chain
- **High throughput** — 10,000+ TPS capacity
- **No front-running** — deterministic transaction ordering
- **Proven tech** — built on battle-tested EOSIO

### Gas fee subsidization

Telos's innovative **gas fee subsidization** model means end users interact with dApps without paying gas fees. Developers cover a small, fixed fee (\~$0.02) per transaction, but users experience frictionless interactions. This dramatically improves UX and removes a major barrier to blockchain adoption.

**How Telos fees work:**

1. Users interact with dApps gas-free
2. Developers pay fixed \~$0.02 fee per transaction
3. Network validators earn from developer fees
4. No variable gas market or price volatility
5. Predictable costs for developers and users

### Carbon-negative operations

Telos is **carbon-negative** and ESG compliant, offsetting more carbon than it produces. Built on efficient Delegated Proof of Stake (DPoS) rather than energy-intensive Proof of Work, Telos consumes minimal power while maintaining high performance and security.

For enterprises and projects prioritizing sustainability, Telos offers high performance without environmental guilt.

### Supported RPC Methods

Telos EVM supports all standard Ethereum JSON-RPC methods:

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

### Code Examples

💻

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

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

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

// Verify we're on Telos
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 40

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

// Deploy contract (users pay zero gas!)
const factory = new ethers.ContractFactory(abi, bytecode, wallet);
const contract = await factory.deploy();
await contract.waitForDeployment();

// 0.5-second blocks = instant confirmation
console.log('Contract deployed:', await contract.getAddress());
```

💻

#### Python (web3.py) — Telos Setup:

```
from web3 import Web3

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

print('Connected to Telos:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 40
print('Latest block:', w3.eth.block_number)

# Fixed low gas on Telos
gas_price = w3.eth.gas_price
print(f'Gas price: {gas_price}')

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

💻

#### WebSocket — Monitor Fast Blocks:

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

// Monitor blocks (every 0.5 seconds!)
let lastTime = Date.now();
provider.on('block', async (blockNumber) => {
  const now = Date.now();
  const blockTime = (now - lastTime) / 1000;
  lastTime = now;
  
  console.log(`Telos block ${blockNumber} (~${blockTime.toFixed(2)}s)`);
});

// Monitor transactions
const filter = {
  topics: [ethers.id('Transfer(address,address,uint256)')]
};

provider.on(filter, (log) => {
  console.log('Fast transfer on Telos:', log);
});
```

## Got questions?  
we are here to help

## What is Telos? 

Telos is a high-performance, carbon-negative EVM blockchain with 0.5-second blocks, 10K+ TPS, and zero gas fees for end users.

## How are Telos blocks so fast? 

Telos uses efficient DPoS consensus built on proven EOSIO technology, achieving 0.5-second block times — fastest among EVM chains.

## Do users really pay zero gas? 

Yes! Telos subsidizes gas for users. Developers pay a small fixed fee (\~$0.02/tx) but users interact gas-free.

## Is Telos EVM compatible? 

Yes, Telos is fully EVM-compatible. Deploy Solidity smart contracts using standard Ethereum development tools.

## What makes Telos carbon negative? 

Telos uses efficient DPoS (no mining), offsets more carbon than it produces, and maintains ESG compliance through verified sustainability programs.

## What is the TLOS token? 

TLOS is Telos's native token used for governance, staking, and as the gas token (though users pay zero).

## Does Telos prevent front-running? 

Yes, Telos uses deterministic transaction ordering preventing MEV and front-running attacks common on other chains.

## What's the tradeoff of subsidized gas? 

Developers pay predictable \~$0.02/tx. This is still very cheap but means gas isn't truly 'free' — costs are shifted to developers.

## Do you support Telos testnet? 

Yes, we provide RPC access to both Telos mainnet (Chain ID 40) and testnet for development.

## What applications run on Telos? 

Telos hosts DeFi protocols, NFT platforms, gaming applications, and enterprise solutions prioritizing speed and sustainability.
