Mantle is a high-performance modular Layer 2 optimistic rollup leveraging EigenDA for data availability and boasting one of the largest ecosystems in L2 with $4B+ in TVL. Backed by BitDAO (now Mantle Ecosystem), the network combines Ethereum security with modular architecture enabling ultra-low fees, high throughput, and rapid ecosystem growth. With native integrations for lending, DEXs, liquid staking, and more, Mantle has emerged as a top-tier DeFi destination.

Access modular DeFi powerhouse
A Mantle RPC node provides applications with access to a modular Layer 2 optimistic rollup that has rapidly become one of the largest DeFi ecosystems. With innovative architecture using EigenDA for data availability and backing from the massive Mantle Ecosystem treasury, Mantle offers developers ultra-low fees, strong liquidity, and access to a thriving user base.
Mantle combines modular architecture (separating execution, settlement, and data availability) with ecosystem backing from BitDAO's multi-billion dollar treasury. This enables aggressive ecosystem growth initiatives, developer incentives, and liquidity programs that have rapidly established Mantle as a top-tier L2 with $4B+ TVL.
Mantle advantages:
Mantle uses EigenDA — EigenLayer's decentralized data availability solution — instead of posting data directly to Ethereum. This modular approach dramatically reduces costs while maintaining security through economic guarantees. EigenDA leverages Ethereum's validator set via restaking, creating a highly secure and cost-effective DA layer.
Mantle's modular architecture:
Mantle's ecosystem includes leading DeFi protocols across all categories: Merchant Moe (DEX), Lendle (lending), mETH Protocol (liquid staking), and hundreds of other applications. The Mantle Foundation provides grants, incentives, and support to developers, accelerating ecosystem expansion.
With substantial treasury resources and aggressive growth strategies, Mantle is positioned as a long-term DeFi hub.
Quick start for developers
Mantle supports all standard Ethereum JSON-RPC methods:
const { ethers } = require('ethers');
const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/mantle/YOUR_API_KEY');
// Verify we're on Mantle
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 5000
// Get MNT balance
const balance = await provider.getBalance('0x...');
console.log('MNT Balance:', ethers.formatEther(balance));
// Interact with Mantle DeFi
const DEX = '0x...';
const dexABI = [
'function swapExactTokensForTokens(uint256, uint256, address[], address, uint256) external',
'function getAmountsOut(uint256, address[]) view returns (uint256[])'
];
const dex = new ethers.Contract(DEX, dexABI, provider);
// Get swap quote on Mantle
const amounts = await dex.getAmountsOut(
ethers.parseEther('1'),
['0xTokenA...', '0xTokenB...']
);
console.log('Swap output:', ethers.formatEther(amounts[1]));from web3 import Web3
w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/mantle/YOUR_API_KEY'))
print('Connected to Mantle:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id) # 5000
print('Latest block:', w3.eth.block_number)
# Ultra-low gas on Mantle
gas_price = w3.eth.gas_price
print(f'Gas price (MNT): {gas_price}')
# Get MNT balance
balance = w3.eth.get_balance('0x...')
print(f'MNT: {balance / 1e18}')const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/mantle/ws/YOUR_API_KEY');
// Monitor new blocks
provider.on('block', async (blockNumber) => {
const block = await provider.getBlock(blockNumber);
console.log(`Mantle block ${blockNumber}: ${block.transactions.length} txs`);
});
// Monitor DEX swaps in $4B+ ecosystem
const DEX = '0x...';
const filter = {
address: DEX,
topics: [ethers.id('Swap(address,uint256,uint256,uint256,uint256,address)')]
};
provider.on(filter, (log) => {
console.log('Swap on Mantle:', log);
