[sk-enya]

Issue Type

[ ] bug report
[x] feature request

Current Behavior

Currently, there is a significant load time on the history page to show the list of transactions available as we fetch all transaction in on call, also hooks is in place to fetch the txs at every interval of 20 seconds which causing the issue.

Expected Behavior

To fix to load time and show the transactions quickly on the history page.

Steps to Reproduce

Suggested Fix

1. we should have pagination support added to the watcher API listed below so that we can load the transaction in chunk the user requested on the first load and on clicking the next set of Txs.

• get.l1.transactions
• get.l2.transactions
• get.l2.pendingexits
• get.layerzero.transactions

2. Should make use of the react-query module on the gateway to fetch the text in a better way.
