Early partners shape the platform.

First in discovery when users search for partners near them.
Featured in Der Leng's social, press, and partner spotlights.
Early partners help set the sector cashback rate before it is locked in Constitution v2.
Sustainability verified. Customers rewarded.
Small and medium businesses face the same sustainability pressures as corporations but with a fraction of the resources. Der Leng gives SMEs a verified, automated way to prove and reward their green practices — without a dedicated ESG team.
Submit your sustainable practices once. AI + admin review issues your partner verification badge.
Your customers earn USDC-backed BOUN on qualifying purchases. Loyalty that compounds.
Der Leng's verification system does the work. You run the business.
ESG reporting that actually proves something.
Corporate sustainability reports are full of pledges. Der Leng replaces pledges with verified, on-chain proof. Every employee action, every offset, every EV fleet km — recorded, verified, immutable.
Every verified action by your team builds your corporate contribution record.
Blue Economy and tree planting acts offset your corporate footprint with real proof, not just certificates.
Issue BOUN to employees for verified sustainable commuting, travel, and acts. Sustainability becomes a benefit, not a burden.
Your verification unlocks premium rewards.
NGOs and conservation organisations are Der Leng's highest-trust partners. An NGO letter or third-party certification issued by your organisation unlocks the premium 1.5× verification tier — the highest multiplier on the platform — for any action your community takes.
| Tier | Who issues it | Multiplier |
|---|---|---|
| Basic | Self-reported | 0.8× |
| Standard | Photo + GPS | 1.0× |
| High | AI verified | 1.2× |
| Premium | NGO / 3rd-party cert | 1.5× |
The acts the world forgets. We record.
Grassroots communities do the most environmental work and receive the least recognition. Der Leng is built to fix that. Village cleanups, community tree planting, traditional fishing practices, local heritage guardianship — all verified, all rewarded in real USDC.
"The ocean gives freely to those who protect it. Earn what the ocean owes you."
National sustainability — verified on-chain.
Der Leng can integrate with national sustainability programmes, environmental ministries, and UNESCO-affiliated bodies to provide a verified, transparent record of citizen and institutional environmental contributions. Constitution v1 rates are locked — no government or admin can alter them. The system is trustless by design.
Issue verified BOUN to citizens who participate in government-led environmental initiatives.
Reward verified visits and conservation acts at nationally protected cultural sites.
All contributions are recorded on-chain and auditable. No black boxes.
