• DappKit
• Easily connect to the Valora wallet with your React Native mobile application
• Valora manages user account, private keys and transaction signing, so you can focus on building your dapp
• Learn more and see the code with the Dappkit truffle box
• Python SDK
• Java SDK

Infrastructure

• Valora provides a clean, intuitive UI where users can send transactions and interact with smart contracts
• Forno
• Node access service so you can connect your dapp to the Celo blockchain without having to run node infrastructure
• ODIS
• Oblivious decentralized identity service
• Lightweight identity layer that makes it easy to send cryptocurrency to a phone number
• Blockscout block explorers
• Alfajores testnet & mainnet
• Stats.celo.org to check network activity and health

Networks

• Alfajores Testnet
• Faucet for free testnet CELO and cUSD
• Forno supports connections to alfajores
• Requires Alfajores Celo wallet for mobile device testing (please request, [email protected])
• Baklava testnet for validators and testing protocol changes

Ethereum Tools

• Similarities between Celo and Ethereum means you can use many of the most popular Ethereum developer tools.
• Celo supports the EVM, so tools for writing smart contracts in Solidity (or any language that compiles to EVM bytecode) are compatible with Celo
• ERC20, NFT (ERC721) and other smart contract interface standards are supported, see Celo for Ethereum Developers
• Truffle
• OpenZeppelin
• Remix

Challenge Description

Build or update cross-chain applications or cross-chain tooling on the Celo blockchain platform. Leverage Optics channels to build new apps and tooling for the cross-chain world or design and develop community materials.

What to Build

• NFT bridge cross-chain application
• Cross-chain lending cross-chain application
• Optics block explorer
• Other tooling for users to use the bridge
• Agent monitoring and health dashboard for public
• Optics Xapps are cross-chain apps focused on Bridging:
  • NFT Xapp - Build an Optics Xapp that allows the bridging of NFT smart-contracts from one chain to the other.
  • Oracle Xapp - Trustlessly send a data feed from one chain to others using Optics

What is Optics

Optics is a new protocol for gas-efficient and trust-minimized interoperability. Its name is an acronym derived from its description: OPTimistic Inter-chain Communication Standard.

Unlike other cross-chain communication systems, Optics is neither a custodial bridge, validator-based bridge, nor header relay. Instead, it leverages an optimistic bridging mechanism to enable radically cheaper communication between chains, while still preserving decentralization.

To learn more about how it works, please check out the protocol docs.

Tools and Resources:

• Join our Discord! Join the #mobiledefi-hackathon and #bridging channels
• Check out the Optics Github repo — we use Discussions!
• Office Hours are happening every week, come get your questions answered and get support from cLabs DEvRel. Check out the Calendar for details
• Check out Building on Celo developer resources to help you get started
• Join events — Fireside chats and follow-along workshops to help you build

Submission Requirements

Have a look at our rules which will serve as a reference to help you structure your project.
Submissions to the Hackathon must meet the following requirements:

• Register your project with https://mobiledefi.devpost.com
• Fork & review https://github.com/celo-org/make-crypto-mobile-hackathon
• Modify with your project details and merge
• Push your project codebase & assets
• Include a text description that should explain the features and functionality of your Project.
• Include a demonstration video of your Project. The video portion of the submission:
  • should be less than three (3) minutes
  • should include footage that shows the Project functioning on the device for which it was built
  • must be uploaded to and made publicly visible on YouTube, Vimeo, Facebook Video, or Youku, and a link to the video must be provided on the submission form on the Hackathon Website; and
  • must not include third party trademarks, or copyrighted music or other material unless the Entrant has permission to use such material.
• Be the original work of the submitter, be solely owned by the submitter, and not violate the IP rights of any other person or entity.
• Access must be provided to an Entrant’s working Project for judging and testing by providing a link to a website, functioning demo, or a test build. If Entrant’s website is private, Entrant must include login credentials in its testing instructions.
• Multiple Submissions: An Entrant may submit more than one Submission, however, each submission must be unique and substantially different from each of the Entrant’s other Submissions, as determined by the Sponsor and Devpost in their sole discretion.

Judging Criteria

• Eligible submissions will be evaluated by a panel of judges selected by the Sponsor (the “Judges”). Judges may be employees of the sponsor or third parties, may or may not be listed individually on the Hackathon Website, and may change before or during the Judging Period. Judging may take place in one or more rounds with one or more panels of Judges, at the discretion of the sponsor.
• Stage One. The first stage will determine via pass/fail whether the ideas meet a baseline level of viability, in that the project reasonably fits the theme and reasonably applies the required APIs/SDKs featured in the Hackathon.
• Stage Two. All submissions that pass Stage One will be evaluated in Stage Two based on the following equally weighted criteria (the “Judging Criteria”):
• Entries will be judged on the following equally weighted criteria, and according to the sole and absolute discretion of the judges:
• Technological Implementation (Does the interaction with the Celo platform demonstrate quality software development?)
• Design (Is the user experience and design of the project well thought out?)
• Potential Impact (How big of an impact could the project have on the Celo platform and wider ecosystem?)
• Quality of the Idea (How creative and unique is the project?)
• The scores from the Judges will determine the potential winners of the applicable prizes. The Entrant(s) that are eligible for a Prize, and whose Submissions earn the highest overall scores based on the applicable Judging Criteria, will become potential winners of that Prize.
• Tie Breaking. For each Prize listed below, if two or more submissions are tied, the tied submission with the highest score in the first applicable criterion listed above will be considered the higher scoring submission. In the event any ties remain, this process will be repeated, as needed, by comparing the tied Submissions’ scores on the next applicable criterion. If two or more submissions are tied on all applicable criteria, the panel of Judges will vote on the tied submissions.
• Winner Announcement Date: November 15, 2021
