You bet your boots you can! And easily too, thanks to AlgoKit and the recently improved Algorand dev UX, offering native Python and TypeScript programming languages, a localnet block explorer, and more. ​Be sure to bring your laptop for this hands-on, technical session, where we’ll cover: * How to onboard to Algorand and start building in 5 minutes * A quick flyover of Algorand’s improved developer UX and industry-leading tools, like LORA (aka the live, on-chain resource analyzer) * How to mint Algorand Standard Assets (ASAs) – from memecoins to tokenized assets **Speakers include:** * Algorand Dev Rels Brian Whippo, Chris Kim, and Gabriel Kuettel * Jerry Chu, CEO & Co-Founder, and Mark Keane, Data Scientist Lofty / Alpha Arcade * Liv Hartoft Borre, Head of Customer Integrations, and Stefan Krumbaek, CCO, ZTLment ​**🌟 2:30 - 4:30 PM | Cross-Chain & Chill** ​Whoaaaa there, builders! Don’t miss these fun and informative chats on going cross-chain, Algorand memecoins, and more. ​Connect with Algodevs from key ecosystem projects. Show us what you’re building. Or just chill! We’re here to hang and connect. ​**🌟 2:45-3:10 PM | Build cross-chain with Router** ​Learn about building killer dApps in a multichain world! * Ram Ramachandran, CEO & Cofounder, Router * Min Wei, EVP of Ecosystem Growth, Algorand Foundation ​🌟 **3:15 - 3:40 PM | Taking DeFi cross-chain** ​The era of interoperable DeFi is upon us.
