Heartswill: the public good API for commerce
Every purchase can do good. Now you can prove it. Here is how one ₹50 travels from a checkout to a classroom and comes back as proof.
Every day millions of us buy gifts, book trips and order things we love. Most brands would like some of that to do good. Most customers would like to believe it does. What has been missing is a simple way to make it happen and to prove it did.
Heartswill is that missing piece. It connects businesses, verified NGOs and their customers. A small part of each order funds a real cause, the NGO delivers it, and sealed proof comes back to the person who paid.
One ₹50 journey
- BuyA small fixed amount of the order is set aside
- RecordOne API call logs the pledge
- PayFunds go straight to the NGO
- DeliverVolunteers hand over the help
- SealPhotos are fingerprinted in the ledger
- SeeThe customer follows the story
- A customer buys something. They shop, book or light a diya as usual. A small fixed amount of that order, say ₹50, is set aside for the cause Heartswill assigned to that business.
- The business tells Heartswill. One API call records the pledge and returns a tracking code. The customer gets a link to follow their own good.
- The money goes straight to the NGO. The business pays the verified NGO running the cause, in advance or monthly. Heartswill never holds the money. Every payment is matched to a bank reference in public.
- The NGO delivers on the ground. Trained volunteers hand over the help, such as a school day for a girl or slippers for a child, with two named witnesses and consent in the local language.
- Proof is sealed for good. Each photo gets a unique fingerprint written into a hash-chained ledger that is anchored to Bitcoin every day. Nothing can be quietly edited afterwards.
- The customer sees the story. The same tracking link now shows the delivery and the sealed photos. Anyone can re-check the whole ledger on their own phone.
Three people, one promise
Businesses
Heartswill assigns you a verified cause. You choose a fixed amount per order and connect with one API call, a plugin or the Shopify app. You pay the NGO in advance, monthly or at checkout, and you get a verified badge and a live impact card for your site.
NGOs
Registered trusts, societies and Section 8 companies are selected after verification. They list a cause with a clear unit and real cost, receive funds directly from partner businesses and prove every delivery from a simple field app. No cut of pledges, ever.
Customers
Nothing extra to pay or sign up for. A tracking link arrives on the receipt, photos of the real delivery follow within about 30 days, and the whole ledger is open to check at any time.
Why you can trust it
Every event on Heartswill becomes a numbered record whose fingerprint includes the record before it. Change one word anywhere and every record after it breaks. Once a day the latest fingerprint is stamped into the Bitcoin blockchain, so even Heartswill cannot rewrite history. Corrections are never edits. They are new public records.
A partner's verified badge works the same way. Its dot turns green only on that partner's own registered website, and only while real pledges keep reaching the Heartswill API. Copy the badge elsewhere and it stays grey.
We have also filed an Indian patent application for Heartswill Field Evidence Capture, the next generation of how delivery proof is captured on the ground (application no. 202611136329, filed 14 November 2026). Patent applied for. No patent has been granted yet. Today's live proof is photo fingerprints, two witnesses and a public ledger anchored to Bitcoin.
Where we are
These are early days. Heartswill opens fully on 1 January 2027, and our first partners are already live. Eternal Repos connected on 10 November and its first pledges reached the ledger the same day.
