Why it is new

What exists today, and what this does differently

What is new

Pay-to-reach exists in several forms; combining AI triage with refundable crypto fees is the uncommon part.

Closest things out there

VipInbox x402 pays recipients USDC for delivered mail, Heed (Taiko) charges onchain fees to reach a recipient, and Inboxly uses refundable deposits; none found adding AI triage.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

How it earns for you

Scam bouncing and the side gate are free for everyone. Creators pay monthly for the knobs, studios pay for a shared gate, and the owner takes a small cut of fees that gate owners choose to keep. Refunds are never cut.

Platform cut of 5% on the free plan and 2% on paid plans, only on fees the gate owner keeps. Escrow gas on Base (under $0.01) can be sponsored by the owner.

The pitch, ready

An AI doorman for your inbox: friends walk in, scams bounce, strangers put down a fee they get back if it was worth your time.

Problem: Creators, founders and small business owners get hundreds of cold DMs a day. The few that matter drown under spam and polished scams, and blocking strangers shuts out real opportunity.

Solution: A triage agent waves known people through and bounces scams before a pay button is ever shown. Genuine strangers put a small USDC fee in escrow on Base, refunded if the message was useful or ignored.

Why now: Small fast models make triage nearly free, USDC on Base settles for under a cent, embedded wallets remove crypto friction, and x402 lets AI agents pay to reach humans under the same rules.

Market: Creators, founders, investors and small studios drowning in cold outreach, plus the coming wave of AI agents doing outreach on their behalf.

The ask: Ten design partners who live in their DMs, a creator hub for the first creator night, and a Base ecosystem grant for the escrow audit.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

  1. Home: meet Funke, 29, a designer in Surulere with 312 requests a day burying her bridal clients.
  2. Rules: write her house rules. Friends and clients walk in, strangers put down a refundable coin.
  3. Gate: run tonight's queue. Tolu walks in, Kwame is asked for the fee, a polished scam bounces.
  4. Owner Agent: the keyword filter failed, and the agent switched to link and sender age.
  5. Tray: Kwame pays, Funke marks it useful and his coin goes back with an escrow receipt.
  6. Bounced: Chidi was bounced by mistake, appeals, and is let in with one tap.
  7. Owner Revenue: change the Creator price in the paywall editor and preview the user Plans screen.
  8. Owner Growth and Roadmap: run a creator night, then request the v2 x402 agents build.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Creators, founders and small business owners get hundreds of cold DMs and emails a day. The few that matter (a client, a supplier, a real collaborator) drown under spam and polished scams, and blocking strangers entirely shuts out real opportunity.

What exists and what is new

Pay-to-reach is not new. VipInbox uses x402 to pay recipients USDC for delivered mail, Heed (an open source Taiko project) charges an onchain fee to reach a recipient, and Inboxly uses refundable deposits. What we did not find is AI triage in front of the fee: an agent that waves known people through, bounces scams before they can pay, and only asks genuine strangers for a deposit that is refunded if the message was useful or ignored. The combination is the uncommon part, not any single piece.

The data it runs on

Message metadata and text read locally or through the user's connected inbox, an allowlist (contacts, client list), link and domain age signals, sender account age, and escrow events on Base. Message content and the allowlist stay off-chain and encrypted; only escrow amounts, outcomes and a message hash are onchain.

1.The mission

Make a person's attention something they control and strangers respect, so that reaching someone new costs a little care instead of nothing, and scammers cannot buy their way in.

2.Why people can't resist it

Silence ends The first night the inbox drops from 300 requests to nine is felt immediately. The weekly hours chart keeps that relief visible.

Fair to senders Senders get the fee back if the message was useful or ignored, so real people do not feel taxed and the owner cannot profit from silence.

The Sunday digest A short weekly ritual: paid messages waiting, refund deadlines, and senders the agent was unsure about. Clearing it keeps a streak.

3.How it works for real

Reach page and wallet: A public reach page per owner. Senders connect with Privy embedded wallets (email or social login) and pay in USDC on Base. No wallet is needed for allowlisted contacts.

Triage agent: A small fast model (for example Claude Haiku 4.5 or GPT 5 mini class via OpenRouter) classifies each message as known, stranger, spam or scam, then a rules layer checks link domain age, sender account age and bulk-send fingerprints. Scams are bounced before a fee is ever offered.

Escrow contract: A minimal escrow contract on Base holds each fee with a deadline. Owner marks useful (refund) or not for me (release, minus a platform fee). No action by the deadline triggers an automatic refund callable by anyone.

Payment rail: USDC on Base, optionally via x402 so agents and apps can pay to reach the owner programmatically under the same rules.

Indexer and inbox store: A lightweight indexer (Ponder or a hosted subgraph) tracks escrow state. Message bodies, attachments and the allowlist are stored encrypted per owner, never onchain.

Notifications: Quiet hours, a morning digest by email or push, and a Sunday summary. Allowlisted contacts can bypass quiet hours.

Shared blocklist: Opt-in sharing of hashed scam domains and phrasing patterns between gates, with no message content shared.

4.Cost per use and pricing

Per message triaged: roughly 600 input and 80 output tokens on a small model, about $0.001 at Haiku 4.5 class pricing ($1 per million input, $5 per million output). Per paid message: an escrow open and a settle on Base, typically well under $0.01 each at normal gas. Example month for one creator: 9,000 messages triaged (about $9 in model cost), 120 paid messages (under $2 in gas), plus hosting around $20. Roughly $30 a month to run.

Creator $9 a month
Custom fee and refund window, quiet hours, voice note reading, Sunday digest, 2% platform cut.
Team $29 a month

5.Growth loop

Every bounce and every fee request carries a small line that the recipient uses a gate, with a link to make one. Senders who get refunds become owners. Creators share the six week card (scams bounced, hours saved), which is the strongest advert.

6.Risks and guardrails

Perceived paywall: Some people will read any fee as rude. Guardrails: allowlist on by default, automatic refunds, and an option for free requests with a lower priority.

Fee as fake legitimacy: Scammers may pay to look legitimate. Scam checks run before a pay button is shown, and paying never adds a verified badge.

Misclassification: The agent will sometimes bounce a real person. Bounced senders see a clear appeal path, and the owner sees uncertain cases in the digest.

Privacy of inbox data: Reading DMs is sensitive. Content is encrypted per owner, never used to train models, and never put onchain.

Regulatory: Holding user funds in escrow may raise money transmission questions in some places. Keep escrow non-custodial in a contract, and get local advice before launching widely.

Platform terms: Some social platforms restrict automated DM access. Start with email and a reach page link, and add platforms only through official APIs.

7.Build order

  1. Reach page with Privy login and USDC on Base
  2. Escrow contract with deadline and auto refund, audited
  3. Triage agent on email first, with allowlist import
  4. Link and sender age checks layered on the model
  5. Morning digest and Sunday summary
  6. Owner dashboard with outcomes and refund history
  7. Opt-in shared blocklist of hashed scam patterns

8.Where this is going

  1. Now
    One gate for one creator's inbox: friends in, scams out, strangers pay a refundable fee.
  2. Next
    Gates across email, DMs and agent requests, with x402 so AI agents pay the same fair price to reach a human.
  3. Later
    A shared, privacy-preserving scam signal network across thousands of gates that kills a new scam within hours.
  4. The world it builds
    Attention is owned by the person it belongs to. Reaching someone new is still possible for anyone, but spam and fraud stop being free.

Costs and tools are estimates at the time of writing. General information only, not legal or financial advice.

Nine routes from one vessel. Tap a port to open its chart.

Why own Gatekeeper

Your attention is the scarcest thing you have, and right now every platform gives it away for free. Own Gatekeeper and strangers pay a small refundable fee into your wallet to reach you, under your brand, with an AI triage you control. The fees, the allowlist and the reputation of a well guarded inbox are yours.

What’s stopping you?

“Will people think charging to DM me is rude?”

Some will. That is why the fee is refundable when you find the message useful, and friends never pay. Frame it as 'I read everything that comes through here', not as a toll.

“What if the AI lets spam through or blocks a friend?”

It will make mistakes in week one. Keep a manual allowlist, review the blocked folder daily for the first two weeks, and tune the rules from what you see.

“I can't code.”

You do not need to. Gatekeeper arrives working, deployed from your own wallet with a written guide for every step. You will click, paste and fill in names. If you ever want a change you cannot make, the custom option or a freelancer can handle it, but the first launch needs no code.

“Is it really mine?”

Yes. The contract is deployed from your wallet on Base, the code sits in your own git repo, and the name and brand are yours. DEPLOYR does not hold your keys or take a cut of what Gatekeeper earns. If you stop paying anyone tomorrow, the app keeps running on your wallet.

“What if nobody uses Gatekeeper?”

That is the most likely early outcome, and it is fixable. The paths below start with you as the first user, then ten real founders, creators and investors who drown in cold DMs you can name today. If ten people you message do not care after you have shown it to them, you have learned something useful in a week instead of a year.

The million-dollar ladder

Two streams: the owner keeps reach fees on their own page, and as an app owner you sell hosted reach pages to other busy people for a monthly plan plus a small cut of fees. This ladder is a target, not a promise.
