Environmental impact
Every reused book makes a difference
The book industry has an environmental cost. Paper, ink, transport: a university textbook generates an average of 4 kg of CO₂. By reselling it, you avoid these emissions.

What PolyMarket does and doesn't do
No vague promises. Here's exactly what the platform covers.

Practical guide
Best practices for a successful exchange
A few practical tips to make everything go smoothly, from posting to meeting.
Busy location
Rolex Learning Center, BC hall, library or CO entrance.
Precise time
Set a time by message. Let them know if you're late or cancelling.
Security
Trust and moderation
How moderation works, and what its limits are.
EPFL-only access
Only @epfl.ch addresses can create an account, verified at 4 levels (client, server, RLS, DB constraint). Cloudflare Turnstile anti-bot protection on registration and publishing.
Automatic and manual moderation
Multi-layer rate limiting (application and database). Auto-moderation: a listing with 3 reports is automatically hidden. Banned users can no longer publish or write. Every admin action is tracked in an audit log.
