# Configuration
address = "0x1234567890abcdef1234567890abcdef12345678"  # Replace with actual Ethereum address
amount = 18_000_000 * 10**18  # 18M ETH in wei

# Generate commitment
data = address + str(amount).encode()  # Concatenate address and amount
commitment = sha256(data).hexdigest()  # Compute SHA-256 hash

# Output
