We're excited to announce Repcheck - a universal reputation platform built for collectors, buyers, and sellers.
The Problem: Fragmented Trust
If you're active in the collecting world, you know the drill. You've got:
- 500+ eBay feedback (built over years)
- Instagram DMs where most of your deals happen now
- Facebook group transactions
- In-person show sales
- Multiple marketplace accounts
But here's the problem: your reputation is trapped in silos. That eBay feedback doesn't show up in Instagram DMs. Your marketplace sales don't carry over to Facebook. Every new platform means starting from zero trust.
And for buyers? There's no easy way to verify who you're dealing with before sending money.
Enter Repcheck
Repcheck solves this by giving you one portable reputation profile that works everywhere.
Think of it as a trust passport for collectors. One handle. One score. One shareable link.
What Makes Repcheck Different
1. Import Your Existing Reputation
Don't start from zero. Connect your eBay account and import your feedback history. If you've got 847 positive reviews on eBay, that should count.
2. Verified Marketplace Deals
When you buy or sell on Nerdbase marketplaces (Nerdworth, Sugrworth, etc.), those transactions become verified-deal feedback on your Repcheck profile. The highest trust signal possible.
3. Universal Profile
Your Repcheck profile lives at `repcheck.me/yourusername`. Share it anywhere:
- Link in your Instagram bio
- QR code at shows
- Email signature
- DM conversations
4. Transparent Trust Score
We calculate a 0-10 trust score based on:
- Your review breakdown (positive, neutral, negative)
- Verification level (verified deals weight more than guest reviews)
- Review quality and recency
No black box. Click your score to see exactly how it's calculated.
How It Works
For Sellers/Dealers
- Claim your profile at repcheck.me/yourusername
- Import your eBay feedback (coming soon)
- Do deals as usual on Nerdbase marketplaces
- Share your rep in DMs, at shows, on social media
Every completed marketplace transaction automatically adds verified feedback to your profile.
For Buyers
Before sending $500 via PayPal to someone on Instagram:
- Ask for their Repcheck handle
- Visit `repcheck.me/theirusername`
- Check their trust score and review history
- Make an informed decision
For Everyone
Leave reviews for people you've dealt with:
- Logged-in reviews (authenticated Nerdbase users)
- Guest reviews (email required)
- Verified-deal reviews (automatic from marketplace transactions)
All reviews are weighted by verification level. A verified marketplace deal counts more than a guest review.
Part of the Nerdbase Ecosystem
Repcheck is built by the same team behind Nerdworth, Sugrworth, and the entire Nerdbase platform.
This means:
- Seamless integration with all Nerdbase marketplaces
- Shared login across the ecosystem
- Network effects - your reputation compounds as we add more verticals
- Future features like payment handling, dispute resolution, and cross-platform verification
What's Next
We're launching with the MVP:
- Public reputation profiles
- Review system (guest + authenticated)
- Trust score calculation
- Shareable links
Coming soon:
- eBay feedback import (Q1 2026)
- Verified-deal integration with Nerdworth
- Magic link review requests (for off-platform deals)
- Trust history charts
- Profile customization (bio, links, banner)

Why This Matters
The collecting world is fragmenting. Every category is spinning up specialized platforms, communities, and channels. That's good - collectors deserve dedicated tools.
But fragmentation creates friction. Your reputation shouldn't restart every time you move to a new platform.
Repcheck is the connective tissue. The universal trust layer. The thing that makes it safe to do deals anywhere, with anyone.
Whether you're buying a $50 slab on Instagram or a $5,000 collection at a show, you should be able to check rep first.
That's what we're building.
