How Rep Score is built
Your RepDex score is a single, portable trust score that combines peer reviews and verified public platform history. Everything is normalized to a 0–100 scale.
Trust score
The headline score. It blends RepDex peer reviews and imported platform reputation, weighted so recent community feedback matters most.
Seller score
Reputation when you are the seller. Combines seller-side reviews and imported public feedback such as eBay feedback scores.
Buyer score
Reputation when you are the buyer. Based only on reviews where the other party rated you as the buyer.
What feeds the score
Every source produces two numbers: a quality (0–100, how good the record is) and a weight (how much that record should count). The score is the weighted average of those sources — nothing is hidden, and every weight is capped so no single platform can dominate.
RepDex reviews
Each review is a 1–5 star grade from the other side of a real trade.
weight = (verified ? 3 : 1) × 0.5^(age_days / 365)
quality = Σ(weight × grade) / Σ(weight) / 5 × 100
Reviews tied to a verified handshake count 3×, and every review's weight halves each year.
eBay feedback
Verified eBay links import feedback score and positive percentage. eBay carries the most platform weight because it is the only connected platform where the transaction itself is verified and both sides were reviewed.
quality = positive_percent
weight = min(feedback_score, 400) / 400 × 65
Full weight at 400 imported feedback — roughly 22 fresh verified reviews.
Reddit connection
A verified Reddit link proves the account is real and established, but karma and account age are not transaction evidence, so they no longer move the weighted average.
weight = 0
bonus = +1 (only if you already have trade history)
Capped at 100, same as the identity bonus.
Discord
Discord publishes no public reputation data.
weight = 0
A verified Discord link proves identity and counts toward tier connections, but never moves the score on its own.
Verified identity
A passed government-ID and liveness check adds a flat bonus.
trust_score = min(earned_score + 3, 100)
A bonus, never a score of its own — with no reviews or imported history you stay unrated no matter how many IDs you pass.
Verified identity
Traders can verify who they are with a government ID and a liveness selfie. RepDex stores only the decision, the legal name and the country — never the document itself — and uses a one-way fingerprint of the document to stop one person running several trader accounts. Verified traders carry the ID Verified badge, and identity verification is required before you can propose or accept a Trade Handshake.
In the score it is deliberately modest: a flat +3 points on top of the score you have already earned, capped at 100. It cannot create a score from nothing, so a freshly verified account with no trade record still shows as unrated. Knowing who someone is and knowing how they trade are two different things — the badge answers the first, the score answers the second.
Verified by handshake
eBay and other marketplaces can prove a transaction happened. Reddit, Discord and in-person deals cannot — which is why a review from those platforms is easy to fake in either direction. A Trade Handshake closes that gap: both traders agree to the items, value and shipping terms before the deal, then both confirm it was completed before reviews unlock.
Because that record exists, a review attached to a completed handshake carries 3× the weight of a standalone review, and the completed deal is published on the Ledger for anyone to check. Standalone reviews still count — they just count less until a deal record backs them up.
Trader tiers
Your trust score measures quality. Your trader tier measures sustained reputation — reviews received, rating, verified connections, and dispute-free standing. Tiers are assigned automatically and are sticky: they never decay from inactivity, only from a confirmed dispute. The separate Authenticated badge is not a tier — it is earned once you verify at least one external account connection.
Ungraded
Default standing. No completed reviews yet.
Common
3+ completed reviews, no unresolved disputes.
Uncommon
25+ reviews, 85%+ rating, no confirmed dispute in the trailing 90 days.
Rare
100+ reviews, 90%+ rating, dispute-free for 6 months, 1 verified connection.
Super Rare
150+ reviews, 95%+ rating, dispute-free for 12 months, 2 verified connections.
Ultra Rare
500+ reviews, 98%+ rating, dispute-free for 12 months, 3 verified connections.
Legendary
1000+ reviews, 98%+ rating, same standing mechanics. Fully automated.
The formulas
Trust score
One weighted average across every source. Scores are clamped to 100 and rounded up to the nearest tenth.
Seller score
Same formula, restricted to seller-side evidence: reviews where you were the seller, plus eBay history imported as a seller account.
Buyer score
Same formula, restricted to buyer-side evidence: reviews where you were the buyer, plus eBay history imported as a buyer account.
Verified trades
Total countable activity: RepDex reviews received plus imported eBay feedback.
Which platforms count
eBay
The only platform we connect to where the transaction is verified and both sides were reviewed. Verified eBay accounts pull public feedback score and positive feedback percentage into the trust, buyer and seller scores, and carry the heaviest platform weight by design.
Confirms the account is real and established — nothing more. Reddit publishes no transaction record, so a verified link adds a flat +1 bonus on an already-earned score instead of feeding the weighted average.
Discord
Discord has no public profile lookup. Accounts are verified manually and appear as a platform badge. Reviews tagged Discord are tracked but marked unverified.
Why is verification required?
A platform link only contributes to your score once it is verified. Verification proves that the RepDex profile actually owns the external account, preventing someone from claiming another trader's reputation. Manual verification is used for platforms without public APIs or profiles.
Recency weighting & red flags
Reputation ages, so recency is built into the score itself: every review's weight halves each 12 months. A clean run from three years ago can't hide how someone trades today. On top of that, red flags call out patterns the number alone would smooth over.
- No activity in 12 months — no reviewed trade in the last year, so the score is stale.
- 3+ negatives in 30 days — three or more reviews of 2 stars or lower landed this month.
- Trending down — the last 90 days average a full star below older history.
Flags are signals, not penalties — they never subtract from the raw score, they just tell you how to read it.
Scores and reviews are informational signals built from past behavior. They are not a warranty of future conduct or of any deal's outcome, and RepDex does not guarantee or insure trades. See the terms.
