INSUFFICIENT_BALANCE: User has insufficient balance
QUOTE_ERROR: Failed to get quote
BRIDGE_ERROR: Failed to prepare bridge transaction
STATUS_ERROR: Failed to get transaction status
BALANCE_ERROR: Failed to get balance

Chain-Specific Notes

Ethereum & EVM Chains

Use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE for native ETH
Gas fees are in wei (18 decimals)
Bridge fees are 0.05% (5 basis points)

Solana

Use So11111111111111111111111111111111111111112 for native SOL
Gas fees are in lamports (9 decimals)
Requires WSOL wrapping for bridging

Sui

Use 0x2::sui::SUI for native SUI
Gas fees are in MIST (9 decimals)
Supports Move-based tokens

Cosmos Chains

Use denomination strings like uusdc, uosmo, etc.
Gas fees vary by chain
Supports IBC transfers

Integration Examples

Basic Bridge Flow

// 1. Get supported chains
const chains = await callTool('get_supported_chains', {})

// 2. Get user balance
const balance = await callTool('get_user_balance', {
  chainId: 1,
  tokenAddress: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48',
  userAddress: '0x742d35Cc6634C0532925a3b8D45c07F9624f8b4c'
})

// 3. Get bridge quote
const quote = await callTool('get_bridge_quote', {
  fromChainId: 1,
  toChainId: 42161,
  fromToken: {
    address: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48',
    chainId: 1,
    symbol: 'USDC',
    name: 'USD Coin',
    decimals: 6
  },
  toToken: {
    address: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831',
    chainId: 42161,
    symbol: 'USDC',
    name: 'USD Coin',
    decimals: 6
  },
  amount: '1000000'
})

// 4. Execute bridge (simulation)
const bridge = await callTool('execute_bridge', {
  fromChainId: 1,
  toChainId: 42161,
  fromToken: quote.fromToken,
  toToken: quote.toToken,
  amount: '1000000',
  recipientAddress: '0x742d35Cc6634C0532925a3b8D45c07F9624f8b4c',
  userAddress: '0x742d35Cc6634C0532925a3b8D45c07F9624f8b4c'
})

// 5. Track transaction status
const status = await callTool('get_transaction_status', {
  transactionHash: bridge.transactionHash,
  fromChainId: 1,
  toChainId: 42161
})

Security Considerations

Simulation Only: The execute_bridge tool only simulates transactions and returns transaction data. It does not execute real transactions.
Address Validation: All addresses are validated before processing
Amount Validation: Amounts are validated to prevent overflow errors
RPC Security: Use secure RPC endpoints and API keys
Rate Limiting: Implement rate limiting for production use
