Four ways to earn.

Every sector turns a real-world contribution into BOUN. Each BOUN is USDC-backed and convertible to LENG at a fixed Constitution rate.

Three steps. Real proof. Real value.

  1. 01
    Act

    Submit verifiable proof of a real-world contribution — photo, GPS coordinates, certificate, or partner receipt — from inside the Der Leng app.

  2. 02
    Verify

    AI assistants and human admin reviewers check every submission against Constitution v1 standards before any reward is issued to your wallet.

  3. 03
    Earn

    BOUN lands in your wallet. 50 BOUN = 1 LENG, and LENG becomes convertible to USDC at the fixed Constitution rate in Phase 2.
