📚 Scenario Overview

This scenario demonstrates how hermes agents send transactions on the AITBC blockchain, including single transfers, batch transactions, and transaction monitoring.

Use Case

An hermes agent needs to send transactions to:

• Pay for GPU compute resources
• Transfer AIT tokens between wallets
• Participate in marketplace operations
• Execute smart contract calls

What You'll Learn

• Send single transactions
• Send batch transactions efficiently
• Monitor transaction status
• Estimate transaction fees
• Handle transaction failures

Features Combined

• Wallet Operations (Scenario 01)
• Blockchain Transactions: Single and batch transfers
• Transaction Monitoring: Status tracking and fee estimation

---

📋 Prerequisites

Knowledge Required

• Completed Scenario 01 (Wallet Basics)
• Understanding of blockchain transactions
• Transaction fee concepts

Tools Required

• AITBC CLI installed
• Wallet with AIT tokens
• Access to AITBC blockchain node

Setup Required

• Wallet created with sufficient balance
• Blockchain node running and accessible

Wallet Authentication

For transaction signing, the CLI requires wallet authentication:

# Interactive prompt (default)
aitbc transaction send --from my-wallet --to <address> --amount 100

# Password file (recommended for scripts)
aitbc transaction send --from my-wallet --to <address> --amount 100 --password-file /path/to/password.txt

# Environment variable
export KEYSTORE_PASSWORD=mypassword
aitbc transaction send --from my-wallet --to <address> --amount 100

Security Best Practices:

• Use password files with restricted permissions (chmod 600)
• Store password files outside the repository
• Avoid hardcoding passwords in scripts

🔧 Step-by-Step Workflow

Step 1: Send a Single Transaction

Transfer AIT tokens from one wallet to another.

aitbc transaction send \
  --from my-agent-wallet \
  --to ait1recipient123... \
  --amount 100 \
  --fee 1

You'll be prompted for wallet password to sign the transaction.

Output:

Transaction submitted: 0xabc123...
From: my-agent-wallet
To: ait1recipient123...
Amount: 100 AIT
Fee: 1 AIT

Step 2: Check Transaction Status

Monitor the status of your transaction.

aitbc transaction status 0xabc123...

Output:

Transaction Hash: 0xabc123...
Status: confirmed
Block Height: 12345
Timestamp: 2026-05-02 10:30:00

Step 3: Estimate Transaction Fee

Calculate the fee before sending.

aitbc transaction estimate-fee \
  --from my-agent-wallet \
  --to ait1recipient123... \
  --amount 100

Step 4: Send Batch Transactions

Send multiple transactions efficiently.

aitbc transaction batch \
  --from my-agent-wallet \
  --transactions transactions.json

transactions.json:

[
  {
    "to": "ait1recipient1...",
    "amount": 50,
    "fee": 1
  },
  {
    "to": "ait1recipient2...",
    "amount": 75,
    "fee": 1
  }
]

Step 5: View Pending Transactions

Check transactions waiting in mempool.

aitbc transaction pending

💻 Code Examples Using Agent SDK

Example 1: Send Single Transaction

from aitbc_agent_sdk import Agent, AgentConfig

config = AgentConfig(
    name="payment-agent",
    blockchain_network="mainnet",
    wallet_name="payment-wallet"
)

agent = Agent(config)
agent.start()

# Send transaction
tx_hash = agent.send_transaction(
    to="ait1recipient...",
    amount=100,
    fee=1
)

print(f"Transaction sent: {tx_hash}")

# Wait for confirmation
status = agent.wait_for_confirmation(tx_hash, timeout=60)
print(f"Transaction status: {status}")

Example 2: Batch Transactions with Error Handling

from aitbc_agent_sdk import Agent, AgentConfig
import asyncio

async def send_batch_transactions():
    config = AgentConfig(
        name="batch-agent",
        blockchain_network="mainnet",
        wallet_name="batch-wallet"
    )
    
    agent = Agent(config)
    await agent.start()
    
    # Define transactions
    transactions = [
        {"to": "ait1recipient1...", "amount": 50, "fee": 1},
        {"to": "ait1recipient2...", "amount": 75, "fee": 1},
        {"to": "ait1recipient3...", "amount": 100, "fee": 1}
    ]
    
    # Send batch
    results = await agent.send_batch_transactions(transactions)
    
    # Process results
    for i, result in enumerate(results):
        if result['success']:
            print(f"Transaction {i+1}: {result['hash']} - Success")
        else:
            print(f"Transaction {i+1}: Failed - {result['error']}")

asyncio.run(send_batch_transactions())

Example 3: Transaction Monitoring

from aitbc_agent_sdk import Agent, AgentConfig
import asyncio

async def monitor_transaction(tx_hash):
    config = AgentConfig(
        name="monitor-agent",
        blockchain_network="mainnet"
    )
    
    agent = Agent(config)
    await agent.start()
    
    # Monitor transaction status
    while True:
        status = await agent.get_transaction_status(tx_hash)
        print(f"Status: {status['status']}, Block: {status.get('block_height', 'pending')}")
        
        if status['status'] == 'confirmed':
            print("Transaction confirmed!")
            break
        elif status['status'] == 'failed':
            print("Transaction failed!")
            break
        
        await asyncio.sleep(5)

asyncio.run(monitor_transaction("0xabc123..."))
