@yarotska.near [Posted on DevHub](/devgovgigs.near/widget/Post?id=1927) ## Idea: Speaking officially: NEARCON IRL Hackathon Bounties Hey hackers, We waited long enough to present our NEARCON IRL Hackathon bounties, but the wait is officially over! You have 10 days to review our sponsored bounties and decide which one are you going to choose. You can buidl either of these or simply submit your project for one of the [main tracks](https://nearcon-hackathon.devpost.com/) – we can't wait to see what you come up with! Without further ado, let me present our challenge partners and some of the most exciting teams in the ecosystem. # SWEAT Pay: Onboarding next billion to DeFi Challenge: People need a simple and affordable way to pay for their everyday necessities in crypto, transaction fees Audience: Near and Sweat supporters, crypto curious, crypto natives Possible solution: A demo of a software or hardware (or both!) prototype that allows regular crypto users to pay with $NEAR in real life References: Trustee, Gnosis Pay, WhiteBIT card A winning solution we’re looking for is: * Innovative: no reinventing the wheel, let’s do cool and unexpected things! * Scalable: ready for potential implementation everywhere from supermarkets to Amazon * Realistic: you understand your legal and technological constraints Winner takes it all: * $6000 in $SWEAT bounty pool for up to 3 best solutions * 6-months incubation with best BD, marketing and tech mentors * Best solution will be implemented on SWEAT for 50 000 real users to crashtest [Details and resources](https://docs.google.com/document/d/1rKK-XLzo4hNysdjHHMscKmSuXeGn-C2K0AlV0A30fRI/edit) Judge: Oleg Fomenko, Co-founder | Sweat Economy # Aurora Cross-Ecosystem Communication Bounty Aurora is an EVM-compatible blockchain built as a smart contract atop the Near blockchain. With this bounty, we want to emphasize the deep link between our ecosystems and demonstrate that Aurora and Near are genuinely the same under the hood. We challenge you to make a fun and impactful project using our cross-contract call (XCC) library – aurora-contracts-sdk. By using it, you can either use Aurora smart contracts on Near or vice-versa – call Near smart contracts inside a Solidity contract on Aurora. That gives a big space for your creativity – now you can create products at the edge of the two ecosystems! From the technical viewpoint, you can use XCC to separate your project architecture into Wasm and Solidity pieces, responsible for the heavier computation and state management respectively, which could be especially beneficial for the game developers. You can read more about this approach here. Feel free to improvise and find new use cases! Develop your projects using the aurora-contracts-sdk library for a chance to win a share of the $3,000 USD (equivalent in stablecoin) prize pool.

In today's digital age with many privacy issues and data leaks, it's important to have platforms that focus on user privacy and let users control their data. Calimero Portal, based on the BOS (Blockchain Operating System), is one such platform. We invite developers everywhere to help improve and grow this platform. Let's make it even better together! Choose between two engaging tasks designed to enhance the Calimero Portal: **Option 1: Enhance Calimero Chat** Your mission, should you choose to accept it, is to augment our chat with groundbreaking features. Here are a few ideas: Integrate NFT stickers. Implement a search feature. Introduce voice chat functionality. Feel free to mix and match or come up with your own innovative solutions. However, keep in mind: Your enhancements should be aligned with the existing features of Calimero Chat. Ensure your proposed features enrich the user experience and align with our platform's vision. **Option 2: Build a Business Application on Calimero Portal** Harness the power of the Calimero Portal to create an application with significant value for businesses. Here are some inspirations: A clone of Google Forms, tailored for the blockchain ecosystem. A scheduling tool like Calendly. A platform for document sharing and electronic document signing. Remember, your application should seamlessly integrate with the existing Calimero Portal and further its goal of user privacy and data ownership. Prizes (equivalent in stablecoin): - First place: 1500usd - Second place: 1000usd [Details and resourses](https://docs.google.com/document/d/1oDKlyI0FOQ2J8rnKE2sJRou4W-yHd-WJDBPAZEFw6Jc/edit?usp=sharing) Judge: Sandi Fatic, Co-founder | Calimero Network # NEARCON VS NEAR Heroes: Side prizes During the NEARCON Hackathon 2023, we wanna spark more excitement and give credit to hackers by introducing a series of unconventional extra prizes. These additional incentives are designed to motivate hackers to gain more exposure for their hackathon submissions, in collaboration with NEARWEEK public votes regarding the winner will be made. During the days of the hackathon the prizes will be live on heroes.build, this is also where acceptance criteria and actual submissions for the side prizes take place. For any questions regarding this, the NEARWEEK and HEROES team will be present at Hacker HQ at the El Cartel coffee booth. Same rules as for the main prizes apply.

Recent Innovations with Account Model: Now with FastAuth, NEP366, mintbase wallet, Keypom with Trial accounts, Namesky we want to showcase the limits of onboarding & near’s account model. Many applications are being hindered by user onboarding as a friction point, and Web3 onboarding still remains one of the biggest pain points in web. Bottleneck in users in the NEAR ecosystem from Web2.5 users. We need to convert these users to the more “native” ecosystem, through progressive onboarding. The following are categories for the bounty that qualify * Keypom: use Keypom SDK, contracts, or fork Keypom to build new onboarding use cases. * Metatransactions: leverage the ability for a third party to pay transaction fees on behalf on account * Abstraction on BOS: build a BOS component, tooling, or gateway that leverages account abstraction * Cross-chain / Remote accounts: build a proof of concept that leverages NEAR’s account model to initiate transaction from another blockchain or Web2 service through a NEAR account Prizes: * 1st Place: $1500 * 2nd Place: $1000 * 3rd Place: $500 [Details and resources](https://near.social/devgovgigs.near/widget/gigs-board.pages.Post?id=1829) Judge: Joe Spano, Co-founder | ShardDog
