About the Hackathon

The Sway Summer Hackathon is a virtual event welcoming developers worldwide to showcase their skills and innovative ideas. The hackathon aims to push the boundaries of what's possible with the Sway language and the Fuel blockchain, and we're inviting you to be a part of it. This event will be hosted on the DoraHacks platform, a community-driven global hackathon organizer with a proven track record of hosting successful events.


We're calling on developers to tackle one of our six bounty categories:

  1. User Onboarding Experience

We're looking for innovative ideas and implementations that can improve the onboarding experience for new users of applications built with Sway. Consider solutions that could minimize or eliminate transaction costs for new users, such as gasless transactions. The objective is to make it as easy and intuitive as possible for new users to get started with applications built on Fuel using the Sway language.

  1. Innovative Payment Applications

We're interested in groundbreaking payment applications built with Sway for the Fuel blockchain. Consider building applications around concepts like stablecoins, micro-payments, and other novel payment methods. The goal here is to challenge the status quo and revolutionize the way we think about digital transactions.

  1. Decentralized Web Infrastructure

This bounty focuses on building a more resilient and decentralized web infrastructure using Sway for the Fuel blockchain. This could include projects focused on Decentralized Identifiers (DIDs), decentralized domain name systems (DNS), software supply chain hardening, and other related areas. The key here is to contribute to a more secure and reliable decentralized web.

  1. Privacy/Security

We value privacy and security. For this bounty, we're seeking applications or enhancements built with Sway that can improve privacy and security within the Fuel ecosystem. This could involve encryption methods, anonymization techniques, or advanced security protocols.

  1. DeFi / RWA

Decentralized Finance (DeFi) and Real World Assets (RWA) are key pillars of the blockchain revolution. We're looking for applications built with Sway for the Fuel blockchain that bring new and innovative solutions to DeFi or that bridge the gap between DeFi and RWA.

  1. Cross-chain Interoperability

Cross-chain interoperability is a crucial aspect of the blockchain ecosystem. For this bounty, we're interested in solutions built with Sway that enhance interoperability between Fuel and other chains. The aim here is to create more open and interconnected blockchain ecosystems.

Judging Criteria

We want to ensure the Sway Summer Hackathon promotes originality and value to the Fuel ecosystem. Therefore, we've set the following judging criteria:

  • Ecosystem Fit: Does the project fill a missing need in the Fuel ecosystem? We're interested in solutions that cover new ground. For ideas and an overview of the ecosystem, see https://fuel.build/
  • Originality: We're looking for fresh approaches. No Uniswap clones or unoriginal ports of protocols from other chains, please.
  • Impact: Does the project have a viable path to adoption that will uplift the Fuel ecosystem?
  • Architecture: We're especially interested in projects that leverage the unique features of the Fuel protocol, such as UTXO for state minimization, parallelism, and improved UX.


  • Your project must be a public open-source GitHub repository.
  • A pitch deck summarizing every feature of your project or a detailed readme file must be submitted.
  • A small demo video (max. 5 minutes). Recommended but not required.
  • You must submit your work before the deadline.
