Understanding Credits

Credits are the currency that powers ExtensionBooster’s review exchange marketplace. They connect extension developers who want reviews with community members willing to provide honest, constructive feedback.

Quick Summary

1 Credit = 1 USD. Earn credits by reviewing extensions, or top up instantly. Use credits to get genuine reviews on your own extensions. The more credits you bid, the faster you receive reviews.

Top Up Credits & Start Getting Reviews Today

Most developers start with 50 credits to gain visibility fast. Higher bids attract reviewers faster.

Using Credits (Bid System)

Credits power the bid system that determines how quickly your extension receives reviews. Manage bids from your Extensions dashboard.

How Bidding Works

Set a bid amount on your extension. Higher bids attract reviewers faster because they earn more per review.

•Minimum 1 credit to be listed in the review exchange
•5+ credits recommended for better visibility
•Higher bids = higher position in the review queue

Example

You set a bid of 10 credits

A reviewer claims your extension

You pay: 10 credits

Reviewer earns: 4 credits (40%)

Daily Review Limit

Control how many reviews your extension receives per day. This feature helps you manage review pacing and budget spending.

How It Works

Navigate to Extension Settings

Go to My Extensions, click on your extension, and scroll to the Boost & Settings section.

Set Your Daily Limit

Enter a number between 0-1000. Set to 0 for unlimited reviews per day.

Click Save

Your daily limit takes effect immediately. The system will stop accepting new review claims once the limit is reached.

When to Use Daily Limits

•Budget control — Spread your credits over more days
•Steady growth — Avoid sudden spikes in reviews
•Testing — Get feedback gradually to iterate

Example Usage

You have 50 credits and want reviews spread across 10 days

Set daily limit to: 5 reviews/day

Result: Consistent review flow without depleting credits quickly

Note: Daily review limits only apply when your extension is boosted. The limit resets every day at midnight UTC.

Withdrawing Credits

Convert your earned credits to real money via Stable coin (USDT). Manage withdrawals from your Billing page.

Withdrawal Process
