# What Are Tools?

In AgentGPT, **Tools** are modular, self-executing programs that combine GPT-4’s strategic planning with blockchain smart contracts to automate complex Web3 workflows. Each Tool acts as a hyper-specialized agent designed to perform tasks like payments, DeFi strategies, or compliance checks—without human intervention.

Unlike traditional bots, AgentGPT Tools are:

* **Autonomous**: GPT-4 generates dynamic strategies, and blockchain executes them trustlessly.
* **Chain-Agnostic**: Operate across Ethereum, Solana, Bitcoin, and 40+ other networks.
* **Self-Healing**: Retry failed transactions across alternate routes.

***

#### **How Tools Work**

Tools decompose high-level goals into actionable steps, leveraging GPT-4 for logic and blockchain for verifiable outcomes.

```

**Key Steps:**

1. **Goal Interpretation**:
   * *User Input*: “Convert 30% revenue to Euro stablecoins, split across EU suppliers weekly.”
   * *GPT-4 Output*: Generates currency conversion, bridging, and payment workflows.
2. **Tool Assembly**:
   * Combines atomic Tools (e.g., DEX Swap + Cross-Chain Bridge + Multi-Send).
3. **Execution**:
   * ERC-7645 smart contracts autonomously handle swaps, bridging, and compliance.

#### **Tool Categories & Examples**

**1. Payment Tools**

**Use Case**: Global payroll automation.\
**Tools Involved**:

1. `CurrencyConverterTool`: Swap profits to EURT/USDC.
2. \`GasRefuelTool\*\*: Auto-funds wallets for transactions.
3. \`MultiSendTool\*\*: Distribute funds to 500+ employees.

**Outcome**: $2.3M payroll processed in 9 seconds with full tax compliance.

**2. DeFi Optimization Tools**

**Use Case**: Maximizing yield across chains.\
**Tools Involved**:

1. \`YieldScoutTool\*\*: Finds highest APY pools.
2. \`AutoCompoundTool\*\*: Reinvests rewards.
3. \`RiskHedgeTool\*\*: Converts volatile yields to stablecoins.

**Performance**: 23% higher APY compared to manual strategies.

**3. Compliance Tools**

**Use Case**: Enterprise transaction screening.\
**Tools Involved**:

1. \`KYCTool\*\*: Screens recipient addresses against sanctions lists.
2. \`TaxReporterTool\*\*: Generates FATCA/CRS reports.
3. \`TravelRuleTool\*\*: Complies with FATF via Chainlink oracles.

**Result**: 100% audit readiness for institutions.

#### **Core Components of a Tool**

| Component               | Function                                | Example Tools                     |
| ----------------------- | --------------------------------------- | --------------------------------- |
| **GPT-4 Strategizer**   | Translates goals into workflows         | Payroll Designer, Yield Optimizer |
| **Smart Contract**      | Executes on-chain actions               | ERC-7645 Swap, Cross-Chain Bridge |
| **Cross-Chain Adaptor** | Routes transactions across networks     | Polygon ↔ Solana Connector        |
| **Compliance Engine**   | Enforces jurisdictional rules           | MiCA Advisor, OFAC Screener       |
| **ZK Auditor**          | Generates audit proofs for transparency | Transaction Validity Prover       |

***

#### **Tool Customization**

**For Developers**:

* Build custom Tools using AgentGPT’s SDK:

  ```python
  # Non-executable example: Create a supplier payment Tool  
  from agentgpt import PaymentTool, ComplianceTool  

  class SupplierPaymentTool(PaymentTool):  
      def __init__(self):  
          super().__init__(currency="EURT", compliance=ComplianceTool(jurisdiction="EU"))  

      def execute(self, amount, recipients):  
          self.convert(amount)  
          self.multisend(recipients)  
  ```
* Submit Tools to AgentGPT’s marketplace to earn AGPT rewards.

**For Enterprises**:

* Whitelabel Tools for internal workflows (e.g., custom invoice reconciliation).

***

#### **Security & Reliability**

* **Encryption**: FHE (Fully Homomorphic Encryption) for sensitive data.
* **Audits**: Tools verified by OpenZeppelin and Certora.
* **Decentralized Governance**: Tools upgraded via AGPT holder votes.
