**TL;DR:** We’re building an open, modular controller for aquariums/terrariums. It has a **Base Mode** (free, no blockchain cost) and an **opt-in Donation Mode** where eligible device events trigger an on-chain **ADA split to NGOs (90%) and the project (10%)**. Looking for feedback, early users, and NGO partners.

**What it is**  
DomuLabs monitors and automates environments (water temp, lighting, oxygen, etc.). The Cardano module lets any user optionally support environmental causes **without paywalls**.

**How it works (Donation Mode)**

- User chooses a monthly tier: **5 / 10 / 30 ADA** (or opt-out = 0).

- When the device completes eligible routines, a contract executes an **ADA split (90/10)** to selected NGO(s) and the project treasury.

- Users see **impact badges and metrics** (e.g., trees supported, litres preserved) in-app; there’s also a **public dashboard** for transparency.

- The **donation smart contract will be open-source**.

**Why Cardano**  
Low fees, strong community around real-world impact, and transparent, auditable flows.

**Status & what I’m asking**

- Preparing a Fund14 proposal and refining scope.

- Seeking: (1) **feedback** on the approach and risks, (2) **NGO introductions/partners** , (3) **beta users** with aquariums/terrariums to pilot.

**Questions to the community**

1. Any red flags in the donation flow?

2. Best practices for NGO selection and reporting on-chain impact?

3. Tips for Fund14 framing (category/risks/milestones)?
