This EIP was implemented on the 10th of November 2025.
Abstract
This proposal introduces a new scoring component to the Ethos credibility system: a Wallet Quality Score. This element evaluates the connected wallets of each user and awards up to 45 additional points toward their Ethos score, rewarding users whose wallets demonstrate strong onchain credibility, longevity, and responsible activity. Conversely, users with only low-quality wallets can receive a penalty of up to -25 points.
The intent is to strengthen onchain trust signals, reduce Sybil manipulation, and reward real users with meaningful wallet histories.
Specification
Overview
The Wallet Quality Score evaluates all connected wallets associated with a user’s account. Each wallet receives an individual score based on measurable, onchain criteria. The score component will then be determined based on the quality of all connected wallets.
Wallet Quality Criteria
Ethos does not intend to publish the specific criteria we are using to compute the wallet quality score. Since this is an inherently gameable metric, our focus is on encouraging users to connect their wallets, transact normally, and demonstrate genuine engagement over time.
Some examples of criteria we have considered, are considering, or intend to use are:
Metric | Description | Signal Type |
Wallet Age | Block timestamp of first transaction; older wallets score higher. | Longevity |
Transaction Count | Total number of valid onchain transactions. | Activity |
Gas Fees Paid | Aggregate gas spent (ETH or Base ETH). | Skin in the Game |
Counterparty Diversity | Number of unique counterparties and contracts interacted with. | Breadth |
Reputation of Interactions | Engagement with reputable, verified, or governance contracts. | Quality |
Low-Risk Behavior | Absence of scam interactions, flagged tokens, or blacklisted contracts. | Safety |
Recency & Consistency | Steady use over time, not bursty or farmed activity. | Authenticity |
We fully expect to iterate on these criteria over time, and to add or remove criteria as we find them to be effective in encouraging genuine, reputable engagement.
Score Component Adjustments
To allow for the wallet quality score we have decided to adjust the following score components:
Eth Address Age: We will remove this component entirely and incorporate it into the wallet quality score.Review Impact: 540 -> 500
