Access Bitcoin's smart contract layer
A Bitlayer RPC node provides applications with access to Bitcoin's first EVM-compatible Layer 2, enabling smart contracts, DeFi protocols, and programmable applications secured by Bitcoin's proof-of-work network. Bitlayer brings Ethereum's developer experience to Bitcoin's massive ecosystem.
Bitcoin is the most secure and decentralized blockchain, but lacks native smart contract capabilities. With $1.3 trillion in market cap, most BTC sits idle. Bitlayer solves this by bringing programmability to Bitcoin while inheriting its security — unlocking BTC for DeFi, NFTs, and complex applications.
Bitlayer advantages:
Bitlayer uses an optimistic rollup design specifically adapted for Bitcoin. Transactions execute on Layer 2 with proofs posted to Bitcoin mainnet. BitVM (Bitcoin Virtual Machine) enables complex verification on Bitcoin without changing its base protocol, ensuring security inheritance.
Bitlayer architecture:
On Bitlayer, native BTC serves as the gas token — no need for wrapped tokens or complex conversions. Users can also bridge other assets from Ethereum and other chains, creating a multi-asset DeFi ecosystem secured by Bitcoin.
This design makes Bitlayer the most Bitcoin-native smart contract platform, while maintaining compatibility with Ethereum's vast developer ecosystem and tooling.
Quick start for developers
Bitlayer supports all standard Ethereum JSON-RPC methods:
const { ethers } = require('ethers');
const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/bitlayer/YOUR_API_KEY');
// Verify we're on Bitlayer
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 200901
// Get BTC balance on Bitlayer
const balance = await provider.getBalance('0x...');
console.log('BTC Balance:', ethers.formatEther(balance));
// Gas price is in BTC (wei)
const gasPrice = await provider.getFeeData();
console.log('Gas price:', ethers.formatUnits(gasPrice.gasPrice, 'gwei'), 'Gwei');from web3 import Web3
w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/bitlayer/YOUR_API_KEY'))
print('Connected to Bitlayer:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id) # 200901
print('Latest block:', w3.eth.block_number)
# Get BTC balance
address = '0x...'
balance = w3.eth.get_balance(address)
print(f'BTC: {balance / 1e18}')const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/bitlayer/ws/YOUR_API_KEY');
// Monitor new blocks
provider.on('block', async (blockNumber) => {
const block = await provider.getBlock(blockNumber);
console.log(`Bitlayer block ${blockNumber}: ${block.transactions.length} txs`);
});
// Monitor contract events
const contractAddress = '0x...';
const filter = {
address: contractAddress,
topics: [ethers.id('Transfer(address,address,uint256)')]
};
provider.on(filter, (log) => {
console.log('Event on Bitlayer:', log);
