I Built a Parking Meter for Paragraphs

The text is baked into the key. Fix a typo in paragraph 3 and it gets a brand new key, while tips already sitting on paragraphs 1, 2 and 4 do not move. Tips attach to what was said, not to a line number that slides the second you add a sentence. I am unreasonably proud of this and it took twenty minutes.

The reader never meets the chain

The app spots MiniPay (Opera’s stablecoin wallet, preinstalled in plenty of places Ethereum gas has never been invited to), auto-connects, and sets feeCurrency to cUSD so gas and tip come out of the same balance. First tap approves an allowance once. Every tap after is one transaction at sub-cent gas. No signup, no “connect wallet” interpretive dance.

The argument I cannot win alone

Here is the part I am genuinely stuck on: how big is a tip that feels like nothing?

The presets are currently $0.001, $0.005, $0.01 and $0.05, and I have no idea which should be the default. Is one cent a tip or a mild insult? Is a tenth of a cent charming, or am I just wasting your tap? I do not know, so I am going to do the radical thing and ask the people who would actually tap it. That is you. There is a comment box.

While I stall on that, I added a custom amount field so you can type your own number. It does one slightly paranoid thing: it resets to a normal preset after a single tap. Because the alternative is that you set it to $5, find a rhythm, and accidentally fund my entire roadmap in a burst of generosity. Flattering, but I would rather you meant it. (There is also a hard cap, for the same reason. I have met enthusiasm before.)

Two lines to put it on your blog

None of this is useful trapped on my domain, so the tipping part is an npm package, @tipitip/embed, and integration is two lines.

React:

import { TipParagraphs } from "@tipitip/embed"; <TipParagraphs articleId="0xbdc473d818a4a15c39941bd9513dbff8eade14a57825619c39884ce36fa40178" /> 

Allergic to React? There is a framework-free web component:

<script type="module" src="https://esm.sh/@tipitip/embed/vanilla"></script> <tipitip-paragraphs article-id="0xbdc473d818a4a15c39941bd9513dbff8eade14a57825619c39884ce36fa40178"></tipitip-paragraphs> 

Drop either into a blog, a docs page, or a Farcaster frame and your paragraphs become tippable. It ships with npm provenance, a signed attestation linking the tarball to the exact commit and CI run, because I would like at least one part of this to look like an adult made it.

Things I shipped, things I have very much not decided

• Which chains next? Celo is where the cent-sized math actually works. The honest catch: the moment I add a second chain, I have to explain to users why they suddenly need a second token for gas, which deletes half the magic. So tell me which chains you want, and whether you are willing to onboard your own readers to fee-currency, because I am tired. (An account-abstraction paymaster is the escape hatch. It is also more work, which is why it is a bullet point and not a feature.)
• The default tip size: see above. Throw numbers at me. I will read all of them.
• Anti-Sybil: off, on purpose. There is a storage gap in the contract so I can add it later without redeploying the universe. Bolting on Sybil-resistance before you have users is solving the wrong problem with great enthusiasm.
• A subgraph: the reader does viem getLogs plus an IndexedDB cache for now. A subgraph is on the list, right after “have enough volume to justify a subgraph.”

Your turn

I will read the comments, and two questions decide real things:

1. What is the largest tip that still feels like nothing to you? Give me a number.
2. Which chain should be next, and do you actually have users there, or does it just sound nice?

If you would rather poke it directly:

• Live: https://tipitip-sable.vercel.app
• SDK: npm i @tipitip/embed
• Code: https://github.com/BRN-SLP/tipitip

Put it on your own blog and send me the link. I will tip your best paragraph. Probably $0.01. Possibly an insult. We are, as established, still deciding.
