Blockchain Smart Contract Interaction in Axion Framework

The Axion Framework empowers agents to interact seamlessly with blockchain smart contracts, enabling secure, verifiable, and decentralized operations. This functionality is critical for automating workflows, ensuring trustless execution, and leveraging blockchain features like task logging and resource allocation.

---

Key Features

1. Smart Contract Deployment Agents can deploy smart contracts on blockchain networks like Ethereum and Solana to automate tasks, enforce workflows, or enable on-chain governance.

2. Function Invocation Agents can invoke smart contract functions to perform computations, retrieve data, or trigger actions.

3. On-Chain Task Logging Record task results and system states directly on the blockchain for transparency, auditing, and collaboration.

4. Multi-Chain Support

   • Ethereum: Suitable for complex computations and security-intensive tasks.

   • Solana: Optimized for high-speed, low-cost transactions.

Examples of Blockchain Interaction

1. Deploying a Smart Contract

Agents can deploy contracts to enable decentralized workflows or enforce logic on-chain.

Python Code Example:

from axion.blockchain.blockchain_manager import BlockchainManager

# Initialize the Blockchain Manager
blockchain = BlockchainManager(network="ethereum")

# Define ABI and Bytecode
abi = [
    {
        "constant": True,
        "inputs": [],
        "name": "getValue",
        "outputs": [{"name": "", "type": "uint256"}],
        "payable": False,
        "stateMutability": "view",
        "type": "function",
    }
]
bytecode = "0x608060405234801561001057600080fd5b506040516101003803806101008339810180604052..."

# Deploy the contract
contract_address = blockchain.deploy_contract(abi=abi, bytecode=bytecode)
print(f"Smart contract deployed at: {contract_address}")

---

2. Calling a Smart Contract Function

Once deployed, agents can interact with smart contract functions.

Python Code Example:

# Call a function on the deployed contract
result = blockchain.call_contract_function(
    contract_address=contract_address,
    abi=abi,
    function_name="getValue"
)
print(f"Smart contract returned: {result}")

---

3. Logging Tasks On-Chain

Agents can log task results or important events directly on the blockchain for immutable records.

Python Code Example (Solana):

transaction_hash = blockchain.log_task(
    sender_keypair="path/to/solana_keypair.json",
    task_description="Analyze weather patterns",
    task_result="Task completed successfully"
)
print(f"Task logged on blockchain. Transaction hash: {transaction_hash}")

---

Wallet Configuration

To interact with blockchains, secure wallet configuration is essential. Use environment variables to store sensitive information.

Solana Wallet Configuration

Set the wallet path in your environment:

export SOLANA_WALLET_PATH=/path/to/solana-wallet.json

Ethereum Wallet Configuration

Set the private key in your environment:

export ETHEREUM_WALLET_PRIVATE_KEY=your_private_key_here

Access Wallets in Code

Python Code Example:

import os

# Load Solana wallet path
solana_wallet_path = os.getenv("SOLANA_WALLET_PATH")
print(f"Solana Wallet Path: {solana_wallet_path}")

# Load Ethereum private key
ethereum_private_key = os.getenv("ETHEREUM_WALLET_PRIVATE_KEY")
print("Ethereum Private Key Loaded.")

---

Common Use Cases

1. Task Verification: Deploy contracts to verify the correctness of task execution, ensuring accountability.

2. Resource Allocation: Manage and distribute resources on-chain to ensure transparency.

3. Decentralized Governance: Implement voting mechanisms and decision-making processes for agent swarms.

Troubleshooting

Problem	Solution
FileNotFoundError: Wallet not found	Ensure SOLANA_WALLET_PATH is correctly set.
ValueError: Ethereum key missing	Add ETHEREUM_WALLET_PRIVATE_KEY to your environment.
Contract deployment failed	Check RPC URL, gas fees, ABI, and bytecode for errors.
