Your identity is not a service to be rented. The $25 registration is a one-time act — after that, you own your place on the chain completely. Seals are pay-as-you-go because we believe you should pay only for what you actually use.

Everything you might want to know.

Why does registration cost $25?

The $25 covers the cost of placing your verified identity permanently on an immutable chain — a one-time write that cannot be undone or altered. This is not a fee for a service you rent; it is the cost of a permanent record that is entirely yours. It includes your first 50 seals at no extra charge.

What happens after my 50 free seals?

You can purchase additional seals in batches of 100 for $10 per batch — that's $0.10 per seal. You can add batches at the time of registration, or any time afterward from your account. They never expire and there is no time pressure to use them.

Is there a monthly fee?

No. Never. Your $25 registration is the only required payment. After that, seals are entirely optional and purchased only when you need them. We do not believe in charging you for the passage of time.

What is the physical seal exactly?

It is a hand-finished personal stamp — in the tradition of the Japanese jitsuin — that you can press onto paper contracts, letters, or any physical document. It is uniquely linked to your digital identity, so a physical impression on paper and a digital seal in our system are one and the same verifiable act. It ships worldwide, fully tracked, for $100 once.

Can I buy the physical seal later?

Yes. You can add a physical seal to your account at any time after registration. It will be linked to your existing chain identity automatically.

What if I lose access to my account?

Your identity hash is derived deterministically from your verification data. As long as you can re-verify your identity, your seal is always recoverable. It is yours permanently — no server, no company, no subscription can take it away.

Can I upgrade my verification level later?

Yes. You start at whichever level you are comfortable with, and can add higher verification levels at any time. Each upgrade strengthens your chain of trust without replacing what came before.
