One donation. Three promises.
Documented milestones. Supporter Pool. Impact record. Explained step by step.
Request concept paperThe lifecycle of a donation
You choose a project
You donate in EUR — processed securely, no technical jargon
Your donation is earmarked for the organisation's project
You receive your digital donation receipt immediately
The project documents a milestone
ChaCha records the milestone
The organisation has confirmed the impact — your receipt now shows the impact record
While your donation flows, the Supporter Pool covers network costs — you never come into contact with them.
Every euro reaches the project.
We say 100% — and we mean 100% for you. No processing fee, no administration charge, no hidden deductions — nothing that reduces your donation. The Supporter Pool is meant to cover the costs of every donation, not you.
Impact projects are built around documented milestones: the project confirms what it has achieved, and we record the evidence. Your donation is earmarked for the organisation's project. We are preparing to hold impact-project funds until a milestone is documented.
- Milestones per project — every record is documented
- Release of funds after a documented milestone — In preparation
- Unique attribution — every donation is traceable
Your donation receipt — and it evolves.
As soon as your donation flows, you receive a digital donation receipt: unique, permanent and tamper-proof — recorded immutably in the Donation Book, with blockchain security added once we're live.
Unlike a conventional receipt, yours is alive. When the project reaches a milestone, your receipt is automatically updated with this information. You see what happens with your donation — from receipt to impact.
- Date and amount
- Project and nonprofit organisation
- Unique receipt number
- Milestone status
You too can help carry the costs of donations.
For 100% of your donation to arrive, the costs need to come from elsewhere. That is what the Supporter Pool is for. It is meant to cover the payment and network costs of donations:
All contributions are publicly recorded — you can see who contributes, how much, and for what.
- Supporters who contribute from €5, monthly or one-time — and see what their contributions enable
- Companies and organisations can contribute voluntarily too
- If the pool falls short, the company behind ChaCha is meant to make up the missing amount. This is planned, not yet promised.
Donations that arrive — and make an impact.
A donation is more than a flow of money. It is a promise: that something concrete happens. With the impact record, we make that promise redeemable.
As soon as the nonprofit documents a milestone — with a photo, report, or receipt — we document the proof and add it to your Digital Donation Receipt. Where available, we automatically read geo-data (EXIF) from images — so every impact can be located spatially.
"5 wells built" — with geo-coordinates and date
"120 children educated" — with half-year report
"2 tonnes of plastic from the ocean" — with photo documentation
For companies: impact records as data foundation for ESG/CSR reports

Frequently asked questions
- Do I need technical knowledge?
- No. The technology runs in the background. You use ChaCha like any normal website.
- Which organisations does ChaCha admit?
- Nonprofits that submit their tax-exemption certificate. We look at the document, admit the organisation and record its date of issue and validity. For Austria and Switzerland we clarify admission case by case.
- What happens if a milestone is not reached?
- We are defining these rules now and will publish them here once they are final.
- Do I get a donation receipt?
- After every donation you get a donation receipt as a PDF, with your address on request. It is not a formal donation confirmation (Zuwendungsbestätigung). You also get the Digital Donation Receipt: a record of your donation, without your name.
- How does the donation receipt differ from the impact record?
- The donation receipt records that your donation has been received. The impact record documents what the organisation has confirmed and evidenced as the project’s result.
- Can I donate anonymously?
- Yes, up to a legal threshold. Above certain amounts, anti-money-laundering law may require identification.
- Where can I see what happens with my donation?
- In your Donation Account, at any time. Plus updates by newsletter, if you wish.
- Is ChaCha's code publicly viewable?
- Not yet in full. APIs and SDKs for partners and developers are available; we are opening the platform itself step by step.
