Network Comparison

​

Bitcoin vs Ethereum: Key Differences

​

Transaction Formats

• Uses UTXO model - transactions consume and create outputs
• Multiple inputs can be combined in one transaction
• Addresses are derived from public keys
• Supports multi-signature transactions natively

• Uses account-based model - transactions modify account balances
• Each transaction has one sender account
• Addresses are derived from private keys
• Supports smart contracts and complex logic

​

Address Generation

• Bech32 format: bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh
• Testnet format: tb1q...
• Generated from public key hash

• Hex format: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb
• 20-byte addresses (40 hex characters + 0x prefix)
• Generated from private key

​

Withdrawal Differences

• Can withdraw from multiple addresses in one transaction
• More efficient for consolidating funds
• Returns withdrawal ID for tracking

• Single address per withdrawal
• Returns transaction hash immediately
• Can check status via transaction receipt

​

Network Selection Guidance

​

Choose Bitcoin (BTC/tBTC) When:

• You need simple value transfers
• You want multi-address withdrawal support
• You’re building payment applications
• You need maximum security and decentralization
• You’re working with Bitcoin-native applications

​

Choose Ethereum (ETH/tETH) When:

• You need smart contract functionality
• You’re building DeFi applications
• You need tokenization (ERC-20, ERC-721, ERC-1155)
• You want faster transaction confirmations
• You’re building dApps or complex blockchain logic

​

Testnet vs Mainnet

​

Testnets

• Development and testing
• No real value at risk
• Faster iteration and experimentation

• tBTC: Bitcoin testnet
• tETH: Ethereum Sepolia testnet

• During development
• Testing integrations
• Learning and experimentation
• Prototyping new features

​

Mainnets

• Production applications
• Real value transactions
• Live user interactions

• BTC: Bitcoin mainnet
• ETH: Ethereum mainnet

• Production deployments
• Real user transactions
• After thorough testing

​

Gas and Fee Handling

​

Bitcoin Fees

• Fees are calculated based on transaction size
• Paid in BTC
• Deducted from transaction amount
• Can be estimated before sending

// Bitcoin withdrawal - fees deducted automatically
const withdrawal = await client.withdraw.createWithdraw({
  networkId: 'your-btc-network-id',
  from: ['address1', 'address2'],
  to: 'recipient',
  amount: '0.001', // Amount after fees
  clientShare: 'your-share'
});

​

Ethereum Gas

• Gas price × gas limit = total fee
• Paid in ETH (or network native token)
• Gas prices fluctuate with network congestion
• Can be estimated before sending

// Ethereum withdrawal - gas deducted from balance
const withdrawal = await client.withdraw.createWithdraw({
  networkId: 'your-eth-network-id',
  from: ['0x...'],
  to: '0x...',
  amount: '0.1', // Amount before gas
  clientShare: 'your-share'
});

​

Network-Specific Examples

​

Bitcoin Address Generation

// Generate Bitcoin address
const address = await client.addresses.createAddressV2({
  reference: 'user-123',
  networkId: 'your-btc-network-id', // Get from getNetworks()
  clientShare: 'your-client-share'
});

console.log('Bitcoin Address:', address.data.data?.address);
// Output: bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh

​

Ethereum Address Generation

// Generate Ethereum address
const address = await client.addresses.createAddressV2({
  reference: 'user-123',
  networkId: 'your-eth-network-id', // Get from getNetworks()
  clientShare: 'your-client-share'
});

console.log('Ethereum Address:', address.data.data?.address);
// Output: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb
