# Wallet Activity Alert

Watch onchain wallet activity and route significant sends or receives into alert workflows.

Use wallet activity recipes when your workflow should respond to transfers, deposits, withdrawals, or contract events.

**Real-Time Compliance Monitoring for Onchain Smart Contracts**

## Pattern

```text
onchain trigger -> threshold condition -> enrich with data -> notify or create follow-up task
```

**Wallet activity alert**

**Onchain event**
  **Trigger filter**
  **Threshold branch**
  **Notify or task**
  **listener match**
  **event context**
  **significant activity**

## Trigger Options

| Trigger | Use it for |
| --- | --- |
| ` erc20-receive ` | Token deposits to a watched address. |
| ` erc20-send ` | Token withdrawals from a watched address. |
| ` eth-receive ` | Native gas-token deposits. |
| ` eth-send ` | Native gas-token withdrawals. |
| ` evm-log ` | Custom smart contract events. |
| ` solana-transaction ` | Solana wallet or event activity. |

## Example Filter

```json
{
  "root": {
    "type": "erc20-receive",
    "payload": {
      "chainId": 8453,
      "toAddress": "0x0000000000000000000000000000000000000000",
      "minimumAmount": "1000000"
    },
    "children": ["send_alert"]
  }
}
```

## Safety Notes

**Separate watch-only and signing workflows**

Monitoring workflows should not automatically move funds unless you have a clear policy gate, simulation coverage, and
  operational review. Keep read-only alerting separate from wallet write actions when possible.
