Pick what your cause needs

A cause gathers signatures or gathers contributions.

Petition cause

To show how many people stand behind what you are asking. Every signature leaves a certificate, and the proof can be checked without asking us.

Charitable cause

For when support alone does not solve what is needed. You say what you are after and anyone can see how it is going.

A signature nobody can alter afterwards

You do not have to take our word for it. The proof lives outside our servers.

Signed and verified

A simple, intuitive process, within reach of anyone.

The document is sealed

A certificate is issued with a corporate seal, and its fingerprint is calculated.

The fingerprint is anchored

Only that fingerprint is written to the public block chain, as an immutable mark.

Nobody’s data goes on the chain. What gets published is an irreversible fingerprint: a fixed-length cryptographic digest, with no personal data.

One person starts a cause. Many finish it

The cause finds its people right where they already gather

Everything in one place, connecting good people.
