Hi folks! 👋 I just put together Copy-n-Paste PAPI — a PAPI Explorer webapp that helps you get hands-on with the Polkadot-API without the tab-hopping. If digging through papi.how or dev.papi.how feels like a maze when you just want to see things work, this gives you a single place to explore and learn by doing. What’s inside: - Browse everything in one go: chain modules, storage, constants, runtime calls, events, and extrinsics. - Test transactions without the risk: simulate first, inspect payloads/signatures, and see decoded events before you broadcast. - Grab ready-to-paste TypeScript: copy snippets straight into your project. - Quick chain/account switcher: hop between relay/system chains and accounts fast. - Built for onboarding: go from reading to simulating to sending with as few clicks as possible. Try the webapp: [https://papi-copy-n-paste-web.vercel.app/](https://papi-copy-n-paste-web.vercel.app/) After a demo, I got encouraging feedback from Shawn Tabrizi (Parity), Jakub (Hydration) and PAPI team to post this here. I’m fairly new to Polkadot myself, coming from other blockchain ecosystems, and I think this can help other ecosystem developers. Quick starter (optional): I also published create-papi-app to scaffold a PAPI project with templates (minimal, vite-react, next-app, node-cli). Run: `npx create-papi-app` Package: [https://www.npmjs.com/package/create-papi-app](https://www.npmjs.com/package/create-papi-app) Feedback welcome: - Webapp UX: what should be one-click? what’s confusing? - Missing examples: storage/transactions/events you’d like prefilled? - Starter gaps: env setup, wallet integrations, SSR patterns, tests? I’m actively looking for feedback and collaborators. If you try it, please share bugs, rough edges, or ideas — happy to pair up or review PRs. PS: I am currently in PBA Bali (Dapps track), if someone wants to chat about this, please find me. I would be glad. Thanks for reading! 🙏 ---

This tool helped me navigate Papi calls for my personal project. \<3 ---

I can not give you PAPI related feedback as I’ve never worked with it… yet 😉 But maybe thats actually good. Here is how I interacted with it: I open up papi-copy-n-paste and immediately my attention goes to the dropdown’s on the left. I click wildly around on them to collapse and hide. Now inside “Balances \> Storage \> Locks” the “Run Query” button is disabled and I am wondering why. I was hoping when I would fill the SS58String I could do the call - but the state didn’t change. Some kind of feedback about why something doesnt work would be helpful here. Furthermore a few times when the Button was available, I received the error: “⚠ Storage key not known for Auctions.AuctionCounter”. If I added the call to the Queue and executed the queue it presented the Queue run to be successful despite the missing key error in the “Auctions.AuctionCounter”. When I have something inside the queue all the other calls become available as well. However, when I run them only the queue is being executed, not the selected call. Idk if this is intended but it feels buggy. “VoterList \> Calls \> rebag” - when I select Alice the button becomes disabled.

I’ll ask a colleague with more dApp and PAPI experience to take a look and share additional feedback. Cheers 🎊 ---

Yup, fixed now, also added many more features. Now we have constants, events, errors Do give it a try folks ![image](https://europe1.discourse-cdn.com/flex005/uploads/polkadot2/original/2X/a/af6214653f8b2efc9df727f63961a76c0f9845c1.jpeg) ---

Really cool tool! Might add it to [hackathon-guide/polkadot-tinkerers.md at 56f28753f063f148909bab34e110b524fd5b3989 · polkadot-developers/hackathon-guide · GitHub](https://github.com/polkadot-developers/hackathon-guide/blob/56f28753f063f148909bab34e110b524fd5b3989/polkadot-tinkerers.md), if you don’t mind 😉 ---

This is super helpful, I was lost in PAPI, this has made it so much easier for beginners to use it. Thanks. ---

Hey folks, would it be helpful if we can connect a real wallet here and make actual queries and transactions, since we have the setup already here? ---

If you go down this path, then it’s probably a great idea to use [DOTConnect](https://dotconnect.dev/) by @tien . It’s pretty awesome! ---

Thank you so much Josep, looks really good.
