Kadir and Griffin here to announce the launch of Lyra. 👋\n\n**TL;DR**\n\nLyra is a platform that makes spending Crypto every day possible. The platform provides an intuitive dashboard & chrome extension that allows you to create Visa cards on demand using the most popular crypto currencies.\n\n**Why we built Lyra? 🤔**\n\nThere’s currently only two methods to use your crypto what it was originally meant for, spending it. You have to send your crypto to an exchange and wait days for it to reach your bank account or hope to find a retailer that’s integrated a crypto payment processor. The reality is crypto users need an intuitive way to spend their crypto daily. Currently, there’s no way to spend crypto on the largest e-commerce platforms like eBay, Walmart, Target, etc without jumping through a bunch of hoops.\n\n**Solution - Lyra 💫**\n\nLyra provides a dashboard and chrome extension that makes spending crypto simple. Our chrome extension provides checkout assistance on top of all the functionality of the dashboard. At checkout on major retailers a Lyra checkout button will appear that displays all available cards to the user and auto fills their info with a single click! Lyra users don't have to expose their private keys or personal information. Your crypto, your keys. Choose any of the major cryptos, load up your balance, and generate your card. In three easy steps you’re ready to spend at any retailer of your choice. **_Check it out._** _👇_\n\n**Checkout**\n\n![uploaded image](/media/?type=post&id=65339&key=user_uploads/1005032/3fccb807-528a-4170-bc18-dd62b6225168)\n\n**Analytics**\n\n![uploaded image](/media/?type=post&id=65339&key=user_uploads/1005032/144dc451-0779-454f-a840-5bef91abacec)\n\n**Dashboard**\n\n![uploaded image](/media/?type=post&id=65339&key=user_uploads/1005032/831b6267-6ac1-4fcf-9ac4-bd45c11790c7)\n\n**Card Creation**\n\n![](https://lh5.googleusercontent.com/vYjyVMZ9EKGC8mMz7lB2GujsShPXQgWYCeywTxCHoVF560gUjgUMOjeta3kXeU0OdF21q4FkclkAuiqGctKddCHaduRwnw4NWR7Bf5YuCivAQKqMYpoMr1vTvYipit7iJloWC7RmTTcOxpARWCp5HHU)\n\n**Our Ask 🙏**\n\n1.

Fraud is rampant, attendees that purchase tickets on the resale market often can't separate authentic tickets from fake ones and if they're able to purchase from authorized issuers the fees can cost up to 30% - 40% of face value. A traditional ticket has no use past the original event. We believe NFTs should serve the purpose of reusable general access tokens.\n\nThe event hosts have no benefit from the resale of their tickets, have no way to get data of the attendee if the ticket was resold, and the costs associated with issuing tickets is high. NFTs serving as tickets brings more revenue to artists, creatives and event hosts in the form of royalties from sales on the resale market, reduced production cost ( event can be created, new NFTs issued and ready to sell in under 5 minutes ), and prevents fake tickets because the blockchain provides us a trusted decentralized source for authentication.\n\n**Solution - NFT Access**\n\nOn NFT Access anyone can create an event. There's options to create multiple ticket tiers using pre-existing collections ( contracts ) or create tiers with new NFTs directly from the website.\n\n![uploaded image](https://bookface.ycombinator.com/media/?type=post&id=64258&key=user_uploads/1005032/bef3d8ca-33da-43be-b3bb-674b3381ecb9)\n\n**_The event page_**\n\n![uploaded image](https://bookface.ycombinator.com/media/?type=post&id=64258&key=user_uploads/1005032/47cccf6f-e78a-4794-9d28-c496d29d17e8)\n\n**_On checkout, attendees can view which NFTs have access to the event._**\n\n![uploaded image](https://bookface.ycombinator.com/media/?type=post&id=64258&key=user_uploads/1005032/9dfbd9e4-3e7d-4d58-b281-541983f13cc9)\n\n\\\n**Let’s connect** 🤝\\\nTwitter: \n\nEmail: [founders@nftaccess.app](mailto:founders@nftaccess.app)\\\n\\\n**NFT Access is publicly available, anyone can use it! 👇**\\\n[**https://nftaccess.app**](https://nftaccess.app)", "url": "https://www.ycombinator.com/launches/GiQ-nft-access-multi-chain-nft-ticketing-platform", "votes": 24, "created_at": "2022-07-01T04:57:34.592Z" } ] } ]
