How it works

A deposit you get back

Joining and proposals are currently free. The deposit is a defence we can switch on for paid lanes or when spam rises — we hold money to stop spam, not to collect it. That is why refunds are the default.

You Gateway canister Reviewed by a human Auto-refund in 14 days ICP Invite Confiscation (spam only — public count) +1

How is this different from a plain form?

It looks like a form, but you do not just send — you deposit. That changes how spam works at the root.

A traditional form

Form Inbox

Free and unlimited to send — real messages drown in the spam pile

This gateway (a canister)

Form + deposit Holds a small deposit × Review To a human

A small deposit per message — mass spam stops being a business

🏦 The form itself can hold moneyNo payment processor, no bank API. The program holds and returns funds directly, which is what makes tiny deposits viable
🤖 Refunds are executed by codeApproved, rejected or left for 14 days — in every outcome the refund is program behaviour, not operator goodwill
📖 A public track recordConfiscation counts and refund totals are public on-chain, so arbitrary operation shows up immediately

Joining and proposals are currently free (no deposit). Deposits apply to paid lanes, and can be switched on if spam rises.

Deposits and the rules of this gateway
  • Deposits are refunded in full whether approved, rejected or expired (minus round-trip transfer fees of about 0.0002 ICP).
  • If no review happens before the deadline (14 days for deposits, 5 days for consultations), the program refunds you in full, automatically.
  • Consultation and PR fees are kept only when the reply or listing actually happens (those two are not refunded afterwards).
  • Confiscation happens only when the operators explicitly judge something as spam (ads, scams, unrelated bulk mail). Verdict counts and amounts are publicly verifiable, and mistakes can be reversed and refunded.
  • ⚠️ Applications are stored on the blockchain. Do not write sensitive information.
  • This gateway is run by ICP Japan, a volunteer-run community. See About for who we are and the Partnership Policy for how listings work.
