# Monitor Account Activity Across Chains

### Introduction

Monitoring transactions across chains (e.g., EVM, Quranium, Bitcoin) is critical for detecting unauthorized access, resolving disputes, and ensuring asset security. This guide explains how to audit activity, use monitoring tools, and respond to anomalies using structured workflows and best practices.

***

### Key Tools for Monitoring

| **Tool**                 | **Purpose**                                                                |
| ------------------------ | -------------------------------------------------------------------------- |
| **Activity Dashboard**   | Central hub to filter, track, and export transactions by chain.            |
| **Blockchain Explorers** | Verify on-chain details (e.g., Etherscan for Ethereum, Quranium Explorer). |
| **Alert Systems**        | Notify you of large transactions, new chain connections, or failed txs.    |

***

### Best Practices

#### 1. Use the Activity Dashboard

Filter and organize transactions efficiently:

| **Feature**          | **How to Use It**                                       |
| -------------------- | ------------------------------------------------------- |
| **Chain Filter**     | Isolate activity by chain (EVM, Quranium, Bitcoin).     |
| **Transaction Hash** | Click to open the transaction in a blockchain explorer. |

***

#### 2. Verify Transactions on Explorers

Cross-check critical details using chain-specific explorers:

| **Bitcoin**  | Input/output addresses, transaction fees.          |
| ------------ | -------------------------------------------------- |
| **EVM**      | Recipient address, gas fees, smart contract calls. |
| **Quranium** | Transaction finality and confirmation count.       |

***

#### 3. Configure Alerts

Customize notifications to stay informed:

| **Alert Type**            | **Recommended Threshold** | **Purpose**                        |
| ------------------------- | ------------------------- | ---------------------------------- |
| **Large Transactions**    | > $1,000                  | Detect unauthorized withdrawals.   |
| **New Chain Connections** | Any                       | Warn about new wallet links.       |
| **Failed Transactions**   | Any                       | Investigate gas or network issues. |

### Step-by-Step Workflow

#### How to Investigate Suspicious Activity

| **Step** | **Action**                    | **Details**                                                             |
| -------- | ----------------------------- | ----------------------------------------------------------------------- |
| 1        | **Filter by Chain**           | Use the Dashboard to isolate the chain with suspicious activity.        |
| 2        | **Review Transaction Hashes** | Check recipient addresses and smart contract interactions on explorers. |
| 3        | **Cross-Reference Addresses** | Match against your saved address book or known contracts.               |
| 4        | **Revoke Access**             | Disconnect suspicious dApps/contracts immediately.                      |

### Common Mistakes to Avoid

| **Mistake**                 | **Risk**                              | **Solution**                       |
| --------------------------- | ------------------------------------- | ---------------------------------- |
| Ignoring small transactions | Hackers test with tiny amounts first. | Investigate **all** transactions.  |
| Not auditing all chains     | Cross-chain breaches go undetected.   | Use the **Chain Filter** weekly.   |
| Stale dApp permissions      | Old approvals may still have access.  | Revoke unused permissions monthly. |

***

### Troubleshooting Unrecognized Activity

| **Issue**                 | **Action**                                                     |
| ------------------------- | -------------------------------------------------------------- |
| Unknown recipient address | Cross-check with your saved addresses or past transactions.    |
| Unfamiliar contract call  | Search the contract address on explorers to verify legitimacy. |
| Balance discrepancy       | Sync your wallet and check for pending transactions.           |

### Note :

Proactive monitoring across chains is essential to safeguard your assets. Use the **Activity Dashboard** to filter transactions, **blockchain explorers** to verify details, and **alerts** to stay ahead of threats. Regular audits and revoking unused permissions minimize risks. **A single oversight can lead to irreversible losses.**
