# Protocols

> DeFi lending protocols supported by Giza agents across multiple chains

## Overview

Giza agents optimize yield by deploying capital across **DeFi lending protocols** on multiple blockchains. Users supply assets and earn interest from borrowers.

## Protocol Selection

### Agent Selection

When activating an agent, you select which protocols it can use:

```typescript theme={null}
await agent.activate({
  owner: userWallet,
  token: USDC_ADDRESS,
  protocols: ['aave', 'compound', 'moonwell'],
  txHash: depositTxHash,
});
```

### Getting Available Protocols

Retrieve supported protocols for a token on your chain:

```typescript theme={null}
const { protocols } = await giza.protocols(USDC_ADDRESS);

console.log('Available protocols:', protocols);
// Output depends on chain:
// Base: ['aave', 'compound', 'moonwell', 'fluid', 'morpho_gauntlet_usdc_prime', ...]
// Ethereum: ['aave', 'compound', 'fluid', 'morpho_usual_boosted_usdc', ...]
```

## Protocol Types

### Core Protocols

Traditional lending markets like Aave, Compound, Moonwell, Fluid, and Hyperlend:

* Direct lending/borrowing
* Pool-based liquidity
* Variable APRs based on utilization
* Audited contracts (for established protocols)

### Morpho Vaults

Optimization layer that aggregates liquidity:

* Built on top of existing protocols
* Managed strategies by firms like Gauntlet, Steakhouse, Felix, etc.
* Can produce higher APRs through optimization
* Additional layer of risk management
* Available on most chains with varying strategies

### Euler Vaults

Modular lending protocol:

* Non-custodial
* Permissionless vault creation
* Flexible risk parameters
* Isolated markets
* Frontier vaults for emerging strategies

## Protocol Risks

<Warning>
  All DeFi protocols carry risk. Giza agents reduce exposure through diversification and optimization, but users should understand what can go wrong:
</Warning>

### Smart Contract Risk

* Protocols are powered by smart contracts
* Bugs or exploits can lead to loss of funds
* **Mitigation**: Audits, time-tested protocols, bug bounties, diversification

### Liquidity Risk

* Sudden large withdrawals can affect availability
* High utilization may delay withdrawals
* **Mitigation**: Diversification across protocols and chains

### Oracle Risk

* Protocols rely on price oracles
* Oracle failures can cause liquidations or losses
* **Mitigation**: Using protocols with reliable oracle systems

### Protocol Governance Risk

* Protocol parameters can change via governance
* Changes may affect yields or security
* **Mitigation**: Monitoring and automatic rebalancing

### Chain-Specific Risks

* Network outages or congestion
* Bridge vulnerabilities (for L2s)
* Chain reorganizations
* **Mitigation**: Choosing established chains

## Protocol Diversification

Giza agents spread capital across protocols to reduce exposure:

1. No single point of failure
2. Access to the best rates across protocols
3. Liquidity spread across multiple pools
4. Protocol-specific risks stay isolated

## Constraints for Protocol Management

Control protocol usage with constraints:

### Minimum Protocols

Ensure diversification:

```typescript theme={null}
{
  kind: 'min_protocols',
  params: { min_protocols: 2 }
}
```

### Maximum Allocation

Cap exposure to any single protocol:

```typescript theme={null}
{
  kind: 'max_amount_per_protocol',
  params: { max_amount: '5000000000' } // 5000 USDC
}
```

### Exclude Protocol

Blacklist specific protocols:

```typescript theme={null}
{
  kind: 'exclude_protocol',
  params: { protocol: 'fluid' }
}
```

### Protocol-Specific Cap

Limit specific protocols:

```typescript theme={null}
{
  kind: 'max_allocation_amount_per_protocol',
  params: {
    protocol: 'morpho_gauntlet_usdc_prime',
    max_amount: '2000000000' // 2000 USDC
  }
}
```

## Protocol Performance

### Protocol Discovery

Get available protocols for a token:

```typescript theme={null}
const { protocols } = await giza.protocols(USDC_ADDRESS);

console.log('Available protocols:', protocols);
// ['aave', 'compound', 'moonwell', 'fluid', ...]

// Select protocols for activation
const selectedProtocols = protocols.slice(0, 3);
```

### Historical Performance

Agents track how capital performs across protocols:

```typescript theme={null}
const { performance } = await agent.performance({ from: '2024-01-01 00:00:00' });

// See allocation across protocols over time
performance.forEach(point => {
  console.log(`${point.date}:`, point.portfolio);
  // { aave: 500, compound: 300, moonwell: 200 }
});
```

## Protocol Updates

### Adding New Protocols

As new protocols launch or existing ones upgrade:

* Giza team evaluates security and liquidity
* Protocols undergo risk assessment
* If approved, added to supported list
* Agents can automatically use new protocols

### Updating Agent Protocols

Change protocols for an active agent:

```typescript theme={null}
await agent.updateProtocols(['aave', 'compound', 'moonwell', 'fluid']);
```

<Warning>
  Updating protocols triggers rebalancing, which incurs gas costs.
</Warning>
