[ECO Bounty] ioTexScan Token Performance Degradation & Data Loading Failure

Severity: High

Impact: The page is virtually unusable on mobile devices. Extreme lag prevents navigation, and the failure to load the data table breaks a primary function of the block explorer.

Environment:

• URL: https://iotexscan.io/tokens

• Observed Behavior: High CPU/RAM usage, screen freezing, and "No Data" result.

Description: The Token Tracker page suffers from significant performance issues. Upon loading, the browser becomes sluggish (unresponsive). While the UI elements (headers/tabs) eventually appear, the actual list of tokens never populates. This suggests a bottleneck in how the frontend processes the API data or a script execution error that crashes the rendering engine.

Steps to Reproduce:

1. Navigate to the Tokens page on a mobile browser.

2. Attempt to scroll or switch between "All Tokens" and "DePIN Tokens."

3. Actual Result: The interface is laggy/stuttering, and the data table shows "No Data" despite the header showing "125 Token Contracts found."

4. Expected Result: Smooth scrolling and immediate population of the token list.

Technical Impact:

• Bottleneck: Possible excessive DOM manipulation or unoptimized JSON parsing.

• UX: Users are forced to refresh multiple times or abandon the page entirely.

Suggestions for the Developers:

• Implement lazy loading or virtualized lists for the token table to reduce the initial render load.

• Check for API timeouts that might be returning "empty" results to the UI before the data is ready.
