# Latest Transactions

> Find recent transactions by function call or event

# Latest Transactions

Fetches recent transactions that call a specific function or emit a specific event.

## Returns

* Transaction hashes with decoded arguments
* Function parameters or event data
* Useful for monitoring activity and finding examples

## Example Queries

```
Show me the last 10 swaps on Uniswap V3
```

```
Find recent mint transactions for this NFT contract
```

```
What are the latest Transfer events from USDC?
```

## Parameters

| Parameter         | Required | Description                              |
| ----------------- | -------- | ---------------------------------------- |
| `type`            | Yes      | `function` or `event`                    |
| `signature`       | Yes      | Keccak hash of function/event (from ABI) |
| `contractAddress` | Yes      | The contract to query                    |
| `blockchain`      | No       | `ethereum` (default) or `base`           |

<Note>
  You don't need to know the signature hash - Claude will look it up from the contract's ABI automatically.
</Note>

### Function Calls

```
Show me the latest deposit() calls on Aave
```

### Events

```
Find recent Transfer events from the PEPE token
```

## Understanding the Output

### Function Call Results

## Common Use Cases

### Monitor Protocol Activity

**You:** "How many swaps happened on Uniswap in the last hour?"

### Find Example Transactions

**You:** "Find me an example of someone using the flashLoan function"

### Track Large Movements

**You:** "Show recent large USDC transfers (look for whale activity)"

### Analyze User Behavior

**You:** "What functions are people calling most on this contract?"

## Function vs Event

| Use Functions When                           | Use Events When                    |
| -------------------------------------------- | ---------------------------------- |
| You want to see how people call the contract | You want to track outcomes/results |
| Analyzing input parameters                   | Tracking token movements           |
| Finding failed transactions                  | Historical data analysis           |
| Debugging contract interactions              | Building activity feeds            |

## Signature Hashes Explained

Each function and event has a unique identifier:

**Function signatures** (4 bytes):

```
transfer(address,uint256) → 0xa9059cbb
```

**Event signatures** (32 bytes):

```
Transfer(address,address,uint256) → 0xddf252ad...
```

Claude automatically handles these - just describe what you're looking for.

## Practical Examples

### Example 1: Monitoring NFT Mints

**You:** "Show me recent mints from the Azuki contract"

**Result:**

```
Recent mint() calls:

1. 0xabc... - Minted 2 tokens to 0xCollector
2. 0xdef... - Minted 1 token to 0xWhale
3. 0x123... - Minted 5 tokens to 0xTrader

Total minted in last 10 txs: 15 tokens
```

### Example 2: DEX Activity

**You:** "What pairs are being swapped most on Uniswap V3?"

**Result:**

```
Recent swap activity analysis:

Most active pairs:
1. WETH/USDC - 45 swaps
2. WETH/USDT - 23 swaps
3. WBTC/WETH - 18 swaps

Average swap size: $12,450
```

### Example 3: Governance Activity

**You:** "Show recent votes on Compound governance"

**Result:**

```
Recent VoteCast events:

1. Proposal #145: 0xVoter voted FOR (250,000 COMP)
2. Proposal #145: 0xWhale voted AGAINST (180,000 COMP)
3. Proposal #144: 0xDAO voted FOR (500,000 COMP)
```

## Combining with Other Tools

1. **Find recent transactions** → `getLatestTransactionsTool`
2. **Analyze specific tx** → `queryTransactionTool`
3. **Understand the function** → `regexCodeAnalysisTool`

## Tips

<Tip>
  Be specific: "deposit" is clearer than "put money in"
</Tip>

<Tip>
  Mention the contract—different protocols use different function names.
</Tip>

## Limitations

<Warning>
  **Historical depth varies.** Very old transactions may not be available.
</Warning>

<Warning>
  **Rate limits apply.** Don't query too frequently for the same data.
</Warning>
