The allocation problem

Every team running a token sale faces the same dilemma: who are these wallets? Without signal, teams either over-allocate to bad actors or under-allocate to their best community members.

The Cambria integration

Cambria pulled Ethos credibility scores via the free API and used them as a multiplier for allocation priority. Human Verified users received an additional bonus on top. No new infrastructure was needed: one API call per wallet, instant signal.

01
Score
Cambria queried Ethos API for each participating wallet’s credibility score. 568 of 960 participants had scores on file.
02
Weight
Credibility scores were used as a multiplier on allocation. Human Verified users got an additional bonus. No manual review needed.
03
Result
Wallets with Ethos scores committed 66% more on average. Reputation predicted conviction.
