Why it is new

What exists today, and what this does differently

What is new

Uses Solana Actions and Blinks so a tip is one scan with no app, and pairs it with a presence stamp that turns passersby into a recognizable regular audience.

Closest things out there

busk.co's BuskPay does QR card and wallet tipping off-chain. I found no Solana Blinks tipping product for street performers or any that issues presence stamps.

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.

The pitch, ready

A chalk-sized Solana Blink that lets anyone tip a street performer in one scan and leaves a dated I was there stamp.

Problem: Street performers play to hundreds of people a night who no longer carry cash. Card readers cost money and setup time, and performers never learn who keeps coming back.

Solution: One printed sign with a Solana Blink: tip a few cents in USDC with no app, straight to the performer's wallet, and get a compressed stamp proven by a rotating code on the sign. Regulars build streaks, vote on encores and get thanked.

Why now: Blinks unfurl in wallets and on the web, Solana fees are a fraction of a cent, and compressed NFTs make a stamp per tip practical.

Market: Buskers, street musicians and market performers in every big city, plus the collectives, festivals and arts councils that support them.

The ask: Pilot with one busking collective and one street festival, and grant support from Solana ecosystem programs.

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

For hackathons and demo days

Your 2 minute demo

Home: meet Ama, 27, violin at Union Sq on Fridays. Nobody has cash.
Sign: pick tips, spot and set, print the chalk sign with a rotating code.
Scans: Rosa tips 25 cents and gets her first stamp; Kenji's sixth Friday makes him a regular.
Scans: a sticker copy shows a red unverified warning and Rosa backs out; a stale photo tips without a stamp.
Crowd: unlock Performer through USDC checkout, then open tonight's encore vote.
Wallet: tips after fees and a receipt showing what is onchain and what is never stored.
Owner Revenue: change the Performer price and tip fee, preview the Plans screen.
Owner Rules and Roadmap: switch off verified only to see the copy take a tip, then request the v2 tonight map.

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

Street performers play to hundreds of people a night who no longer carry cash. Card readers cost money and set up time, and even when people tip, the performer never learns who keeps coming back.

What exists and what is new

Cashless busking already exists: busk.co's BuskPay offers QR card and wallet tipping off chain, and generic tip QR pages are common. Research found no Solana Blinks tipping product for street performers and none that issues dated presence stamps. What is new is the pairing: a one scan Blink tip with no app, plus a stamp that turns passersby into a recognizable regular audience. Research verdict: fresh, high novelty, small build.

The data it runs on

The performer's wallet, name, photo and spots; tip transactions in USDC on Solana; compressed NFT stamps (date, spot, set, stamp number); rotating sign codes for presence; opt in reminder contacts. No listener names, faces or locations are stored.

1.The mission

Anyone who stops for a street performer can thank them in one scan, and every performer can know the faces that keep coming back.

2.Why people can't resist it

A row of Fridays Each visit adds a dated stamp. Regulars see their streak and want the next one.

Regulars get a voice After a set number of Fridays, regulars vote on the encore and get a thank you from the performer.

25 cents is enough Tiny tips with near zero fees let people who would have walked past give something.

3.How it works for real

Solana Action and Blink: A Solana Actions endpoint returns a USDC transfer to the performer's wallet. The Blink unfurls in wallets and supported sites; the QR encodes a solana-action URL that opens in the scanner's wallet.

Verified performer: The Action is registered so wallets show it as trusted, with the performer's photo and name before payment. Unregistered copies show as unverified.

Presence stamps: Compressed NFTs minted with Metaplex Bubblegum into a performer owned Merkle tree. A stamp is only issued when the scan includes the current rotating code shown on the sign.

Rotating code: A cheap phone or e-ink screen on the case shows a code that changes every 10 minutes, signed by the performer's key. Works underground with no GPS.

Crowd agent: A small model tier (for example Claude Haiku or a similar tier via OpenRouter) writes the Saturday summary: tips, returning stamps, which set held people. It never sees personal data.

Indexer and reminders: Helius webhooks index tips and stamps into a simple database; opt in reminders go out by email or Telegram, once a week at most.

4.Cost per use and pricing

A Solana transfer costs a base fee of about 0.000005 SOL, a fraction of a cent. Compressed NFT stamps cost well under a cent each once the tree is paid for; a tree for about 16,000 stamps costs on the order of a few dollars in rent. A weekly summary on a small model tier is under 1 cent. Example month for one performer: 1,600 tips and stamps, roughly $3 to $6 all in, plus hosting.

Free sign $0

One spot, tips and stamps, printable sign. The owner takes a 1% fee on tips.

Performer $4 a month

Several spots, rotating code screen app, regulars page, encore votes, Saturday summary.

Collective $25 a month

For buskers' groups and markets: many performers, shared map of who plays where tonight.

5.Growth loop

Every sign is an ad on a busy platform. Listeners who collect stamps share their streak, and performers recommend it to each other at the same spots. Busking collectives and street festivals bring many performers at once.

6.Risks and guardrails

Fake QR stickers: Someone can paste a copied code. Verified registry status, the performer's photo before payment and a foil seal on printed signs reduce this; performers can report copies.

Local rules: Some transit systems and cities license busking or ban solicitation. The app links to local rules and never claims a spot is permitted.

Privacy: Stamps are tied to wallets, not names. No location, face or contact data is stored without opt in.

Wallet friction: Scanners without a crypto wallet cannot tip by Blink. A card fallback through a payment provider can be added later.

Taxes: Tips are income for the performer. The app gives a yearly export but no tax advice.

OWNER PLAYBOOK

Own it, then chart your voyage

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

Why own Busker Blink

Busker Blink gives a street performer a printable QR that takes USDC tips in seconds and hands every tipper a dated 'I was there' stamp. Owning it means the performers on your network, the stamps their fans collect and the small fee on each tip all belong to you, not to a payments giant. You become the person in your city who helped buskers get paid and see who keeps coming back.

What’s stopping you?

“I can't code.”

The Blink and sign template are ready. Your work is printing signs, standing next to a performer for an hour and helping the first fans scan.

“Most people don't have USDC on Solana.”

True, and that is the biggest limit. Keep the cash hat out alongside the sign, and lead with fans who already have Solana wallets. Growth will be slower than card tipping.

“Is busking with a QR legal?”

Busking rules depend on your city, and some require a permit. The QR does not change that, so check local rules with the performer before printing.

“Is it really mine?”

Yes. The Blink, fee wallet and performer list are yours, and DEPLOYR takes nothing after purchase.

“What if it breaks?”

Tips go straight to the performer wallet, so nothing is stuck if the page fails. Setup issues are covered by the get-it-shipped promise.

The million-dollar ladder

You take a small, visible fee on each tip and charge venues and markets a monthly plan to put Busker Blink signs at every stall or stage. Reaching $1M a year is a target, not a promise, and tip volume per performer is usually small.
