Transaction ModelUTXO (Unspent Transaction Output)Account balance
Multi-address Withdrawal✅ Supported❌ Single address only
Gas/FeesTransaction-based feesGas price × gas limit
Smart Contracts❌ Limited (Bitcoin Script)✅ Full EVM support
Token Standards❌ Not supported✅ ERC-20, ERC-721, ERC-1155
Confirmation Time~10 minutes~15 seconds (varies)

​
Bitcoin vs Ethereum: Key Differences

​
Transaction Formats

Bitcoin:
  • 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
Ethereum:
  • 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

Bitcoin Addresses:
  • Bech32 format: bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh
  • Testnet format: tb1q...
  • Generated from public key hash
Ethereum Addresses:
  • Hex format: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb
  • 20-byte addresses (40 hex characters + 0x prefix)
  • Generated from private key

​
Withdrawal Differences

Bitcoin Withdrawals:
  • Can withdraw from multiple addresses in one transaction
  • More efficient for consolidating funds
  • Returns withdrawal ID for tracking
Ethereum Withdrawals:
  • Single address per withdrawal
  • Returns transaction hash immediately
  • Can check status via transaction receipt
See the Withdrawal Workflow guide for detailed examples of network-specific withdrawal behavior.

​
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

Purpose:
  • Development and testing
  • No real value at risk
  • Faster iteration and experimentation
Available Testnets:
  • tBTC: Bitcoin testnet
  • tETH: Ethereum Sepolia testnet
When to Use:
  • During development
  • Testing integrations
  • Learning and experimentation
  • Prototyping new features

​
Mainnets

Purpose:
  • Production applications
  • Real value transactions
  • Live user interactions
Available Mainnets:
  • BTC: Bitcoin mainnet
  • ETH: Ethereum mainnet
When to Use:
  • Production deployments
  • Real user transactions
  • After thorough testing
Always test on testnet first! Mainnet transactions involve real value and cannot be reversed. Test thoroughly on testnet before deploying to mainnet.

​
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
Example: 
// 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
Example: 
// 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'
});
Gas prices vary significantly. During high network congestion, consider waiting or using gas price estimation tools to optimize costs.

​
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.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.address);
// Output: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb
