Blockchain Integration

Aether integrates blockchain technology for secure, on-chain decision-making.

It allows agents to interact with blockchain networks like Ethereum and Solana, enabling trustless operations and verifiable task execution.

---

Key Features

• Smart Contract Deployment: Deploy contracts to automate task verification and execution.

• On-Chain Decision-Making: Nodes interact with blockchain for trustless operations and decentralized coordination.

• Secure Wallet Management: Wallet configurations are securely managed using environment variables for paths and private keys.

---

Example: Deploying a Smart Contract

Here’s how to deploy and interact with a smart contract on Ethereum using Aether’s Blockchain Integration module:

from src.utils.blockchain_manager import BlockchainManager

# Initialize the Blockchain Manager
blockchain = BlockchainManager()

# Define contract ABI and Bytecode
abi = [
    {
        "constant": True,
        "inputs": [],
        "name": "getValue",
        "outputs": [{"name": "", "type": "uint256"}],
        "payable": False,
        "stateMutability": "view",
        "type": "function",
    }
]
bytecode = "0x608060405234801561001057600080fd5b5060405161010038038061010083398101806040528101908080518201929190505050806000819055505060d58061003e6000396000f3fe6080604052600080fdfea165627a7a723058202cfa2cf67d..."

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

# Interact with the contract
result = blockchain.call_contract_function(contract_address, abi, "getValue")
print(f"Result from contract: {result}")

Managing Wallets Securely

Aether supports secure wallet management by dynamically retrieving wallet configurations using environment variables.

---

Solana Wallet

Set the wallet path using the SOLANA_WALLET_PATH environment variable:

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

Ethereum Wallet

Set the private key using the ETHEREUM_WALLET_PRIVATE_KEY environment variable:

ETHEREUM_WALLET_PRIVATE_KEY=your_ethereum_private_key_here

---

Code Snippet for Wallet Loading

import os

# Load wallets securely
solana_wallet_path = os.getenv("SOLANA_WALLET_PATH")
ethereum_private_key = os.getenv("ETHEREUM_WALLET_PRIVATE_KEY")

print(f"Solana Wallet Path: {solana_wallet_path}")
print("Ethereum Private Key Loaded.")

---

Common Issues and Troubleshooting

• Problem: FileNotFoundError: Solana wallet path not found. Solution: Ensure the SOLANA_WALLET_PATH environment variable is set correctly.

• Problem: ValueError: Ethereum private key not configured. Solution: Set the ETHEREUM_WALLET_PRIVATE_KEY environment variable.

• Problem: Contract deployment failed. Solution:

  • Verify your RPC URL is correct.

  • Ensure your Ethereum account has sufficient funds for gas fees.

Wallet Configuration

Environment Variables for Wallets

Wallet paths and private keys are securely managed using environment variables. This approach ensures sensitive data is protected and avoids hardcoding values in source files.

---

Referencing Wallets in YAML

In the config.yaml file, wallets are referenced dynamically using their respective environment variables:

blockchain:
  solana:
    wallet_env_var: "SOLANA_WALLET_PATH"
  ethereum:
    wallet_env_var: "ETHEREUM_WALLET_PRIVATE_KEY"

---

Instructions for Developers

1. Set the Environment Variables: Add variables to your .env file or export them in your shell:

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

2. Edit the YAML File: Specify the environment variable names for wallet configurations:

   solana:
     wallet_env_var: "SOLANA_WALLET_PATH"
   ethereum:
     wallet_env_var: "ETHEREUM_WALLET_PRIVATE_KEY"

3. Run the Framework: The framework automatically loads these variables at runtime:

   from src.utils.blockchain_manager import BlockchainManager
   blockchain = BlockchainManager()
   balance = blockchain.solana_get_balance("your_solana_address_here")
   print(f"Solana balance: {balance}")

---

Security Benefits

• Environment-Specific: Easily set different wallets for development, staging, and production environments.

• No Hardcoding: Protects sensitive data from being exposed in source control.

• Scalability: Works seamlessly in CI/CD pipelines and cloud-based deployments.
