Four steps to start trading
Every trader clears the same four checks before their account goes live, usually within 24 hours.
Open your account
Create your account with email or Google. Add your profile, country, LinkedIn, and choose your expert categories.
Pass the market eval
Take a short assessment in your chosen categories. Demonstrate your expertise and unlock the next step.
Verify identity
Complete identity verification (KYC). Once approved, you get full access to the dashboard and paid tasks.
Start trading
Complete annotation tasks at $40–$150/hr and withdraw your earnings directly to your crypto wallet.
Three kinds of listings
Every market listing reduces to one of three order types. Your expertise decides which one you fill.
Rate & rank AI answers
Why
Comparing model responses teaches the AI which answers are actually correct, helpful, and safe.
How
Read a prompt and two or more model answers, then rank them and explain what makes the best one better.
Rank these responses
- Is the answer factually correct?
- Does it fully address the question?
- Is the reasoning sound, not just the result?
- Would an expert in the field approve it?
