GUIDES / QUICKSTART

Submit your first proof

WCN is an evidence-first network: work is settled against proofs, not promises. This guide takes you from zero to a verified submission. You'll need a funded account and about a minute.

³
Everything you submit stays private until review clears. Only an anonymized summary is ever published.

Authentication

Create a secret key in the dashboard and export it. Every request is authenticated with a bearer token; never ship a sk_live key to the browser.

$ export WCN_KEY=sk_live_2aF…

Quickstart

Install the SDK, then submit evidence against an open task.

1
Install the SDK
Available for Node 18+ and Python 3.10+.
2
Find an open task
List deals with status=open and pick one to satisfy.
3
Submit the proof
Post your evidence URI. You'll get a review status back immediately.
