Calculate the cost difference between minting POAPs on xDAI versus Ethereum mainnet. POAPs are minted on the xDAI sidechain for minimal gas fees, while Ethereum mainnet fees can be significantly higher.

Why xDAI? POAPs are minted on the xDAI sidechain for minimal gas fees (typically $0.01 per POAP), making them accessible for large events with thousands of attendees.
Proof of Attendance Protocol (POAP) is a blockchain‑based system that issues digital badges as non‑fungible tokens to prove that someone attended a specific event. Since its debut at ETHDenver 2019, POAP has become the go‑to way for organizers to turn a moment into a verifiable, collectible token.
Traditional NFTs often chase price, but POAP flips the script. Its purpose is purely attestation-not speculation. That focus gives holders a personal “passport” of experiences, while giving event teams a tamper‑proof roll‑call.
Every POAP starts as an ERC‑721 token on Ethereum. To keep gas cheap, the token is later bridged to the xDAI sidechain managed by MakerDAO. Each token contains:
This workflow is designed for both tech‑savvy organizers and casual community managers. No smart‑contract coding is required unless you want custom logic.
Beyond crypto meetups, dozens of brands have adopted POAP:
These examples show how POAP bridges the gap between DeFi‑centric communities and mainstream audiences.
Physical tickets can be lost, faded, or forged. POAPs offer three concrete advantages:
Because the protocol is open‑source, developers can build new experiences that read a holder’s POAP collection automatically.
POAPs are not designed as high‑value collectibles. Trading them for profit goes against the original intent and can dilute the community‑building purpose. Additionally, users need a wallet that supports xDAI; newcomers sometimes stumble over the “bridge” step. Finally, the visual design of each badge is only as good as the event organizer’s graphics, so low‑effort images can make a badge feel cheap.
Many projects already treat POAPs as a resume entry. Imagine a future where your POAP collection proves you’ve spoken at a conference, contributed to an open‑source repo, or completed a blockchain certification. The protocol roadmap mentions:
| Feature | POAP | Generic NFT | Physical Ticket |
|---|---|---|---|
| Primary purpose | Proof of attendance | Ownership of digital asset | Entry permission |
| Cost to mint | Low (xDAI gas) | Varies, often high | Printing & logistics |
| Resale market | Discouraged | Active marketplace | Not applicable |
| Verification | Blockchain ledger | Blockchain ledger | Holograms, barcodes |
| Community perks | Unlocks roles, airdrops | Depends on project | Usually none |
In a world where digital experiences keep expanding, Proof of Attendance Protocol gives you a simple, verifiable way to turn moments into lasting tokens. Whether you’re a community manager, a brand looking for new fan engagement, or an individual collector, POAP offers a durable, blockchain‑backed souvenir that can evolve into a credential for the future.
You need a wallet that supports the xDAI network, such as MetaMask. The POAP platform will guide you through adding the network if you don’t have it already.
Technically they can be transferred, but the community discourages trading because it undermines the badge’s purpose as personal proof of attendance.
Minting occurs on the xDAI sidechain, where fees are typically a few cents, far cheaper than Ethereum mainnet.
Yes. Companies can issue POAPs for repeat purchases or event check‑ins, then grant exclusive discounts to badge holders.
There’s no hard cap; some large conferences have minted tens of thousands of badges in a single day.
POAPs are honestly one of the few crypto things that actually feel meaningful. I’ve got badges from DevCon, a local book club meetup, and even a Zoom workshop on composting. It’s wild how something so simple turns moments into digital heirlooms. No one’s selling these on OpenSea, and that’s the point.
My grandma even got one for attending her first crypto Q&A. She doesn’t know what a wallet is, but she’s got a little badge that says ‘I was there’ - and that’s enough.
Stop romanticizing this. It’s just a glorified QR code that costs $0.03 to mint and gets thrown into a wallet like spam. Most people who collect these don’t even remember what event they got them for. And don’t get me started on the ‘community building’ nonsense - it’s just a vanity project for influencers who want to look like they’re ‘in the space’.
There’s something quietly profound about POAPs. They don’t ask you to invest, speculate, or prove your wealth - they just ask you to show up.
Human beings have always marked moments: cave paintings, wedding rings, handwritten letters. POAPs are just the next iteration - a digital equivalent of a pilgrim’s shell or a soldier’s dog tag. It’s not about value. It’s about presence.
And maybe that’s why it resonates. In a world obsessed with growth and ROI, POAPs say: ‘You were here. That matters.’
I love how low-key this is. No hype, no rug pulls, just a little badge that says you showed up. I’ve got one from a friend’s birthday party in Austin - yeah, really.
It’s nice when tech feels human instead of transactional. Also, the xDAI gas thing is genius. No one gets scared off by $200 fees just to prove they attended a Discord AMA.
Keep it simple, folks. 😊
This is why America’s crypto scene is so pathetic. You’re celebrating a $0.02 digital sticker like it’s the second coming. Meanwhile, real economies are collapsing and you’re out here collecting ‘proof’ you went to a ‘web3 brunch.’
And don’t tell me ‘it’s not for speculation’ - everyone’s already flipping them. You think the U.S. Open is doing this for the ‘community’? They’re mining data. And you’re just the product.
Pathetic. And yes, I’m still mad I didn’t get one from the Ethereum summit. But I’m not gonna lie about it.
Interesting how POAPs sidestep the usual NFT drama. No blue checks, no ape avatars - just clean, verifiable attendance records.
What’s underrated is how this enables offline-to-onchain identity. Think of it like a decentralized LinkedIn badge. I’ve seen communities use them to auto-grant Discord roles, or unlock exclusive AMA access. It’s low-friction credentialing.
And honestly? The xDAI bridge is the unsung hero here. Gas fees on mainnet would’ve killed this before it started.
POAPs are real. I got one from a coding workshop in Bangalore. No one paid for it. No one sold it. I just kept it. It means something. Simple. No noise.
Oh wow, so now we’re giving out digital merit badges for showing up to a Zoom call? How noble. I’m sure the 14-year-old with 37 POAPs from ‘Crypto Yoga’ feels very accomplished.
And yes, I know the protocol says ‘don’t trade’ - but you’re telling me nobody’s listing them on Blur? Please. The moment something is on-chain, it becomes a speculative asset. The ‘ethics’ are a nice story for PR.
Also, typo: ‘Non-fungible Token (NFT)’ - you said it twice in one sentence. I’m not mad. Just… observing.
i just got my first poap yesterday from a local coffee shop’s blockchain meetup?? i didn’t even know what it was until my friend showed me. now i’m obsessed. like… i have a badge for drinking cold brew with people who talk about smart contracts. that’s kinda beautiful??
also i accidentally sent mine to my friend’s wallet and now we’re arguing about who owns it. oops.
POAPs are the only crypto thing I’ve ever actually used. I’ve got one from the Ethereum Foundation’s open house last year - it unlocked a free NFT from a dev I admire. Now I’ve got a whole folder of them in my wallet. I check them like a digital scrapbook.
And yeah, I’ve got the one from the U.S. Open. I showed it to my dad. He didn’t get it. But he smiled. That’s enough.
The real power of POAP isn’t in the badge - it’s in the metadata. When you start linking them to verifiable actions - speaking at a conference, submitting a PR, attending a workshop - you’re not just collecting souvenirs.
You’re building a decentralized transcript. Imagine applying for a job and your POAP collection proves you’ve contributed to 12 open-source projects and attended 5 blockchain ethics panels. That’s not hype. That’s a new kind of resume.
And if that’s the future, we should be building tools to curate, not just collect.
