During 3 days (October 28 - 30), hackers from all over the world gathered at theĀ Academia das CiĆŖnciasĀ in Lisbon for hacking. For this occasion, we sponsored 3 open bounties for bold hackers eager to build onĀ FuelĀ Beta-1Ā testnet usingĀ Sway:
-
š„Ā First PrizeĀ ā $3,000
-
š„Ā Second PrizeĀ ā $2,000
-
š„Ā Third PrizeĀ ā $1,000
š The winners
Let's go over the winning projects:
š„ First Prize ā Authsome
Authsome implements a multi-signature wallet using the predicate system of the FuelVM and Sway. This wallet is then used as the basis for a pluggable authentication infrastructure, similar toĀ Web3Auth.
This project leverages the power of account abstraction and multi-signatures to create Web2-like experiences with Web3 custodial properties.
Check out their demo video below:
How does it work?
You first need to log in with an email address and a password of your choice. Authsome will then generate a 2 of 3 addresses multi-signature wallet, which means that you need 2 addresses to execute a transaction or log in to Authsome. Each key will be stored in different places.
Then you're all set to execute blazingly fast payments: You log in with your password to unlock the first key, and the second key is loaded from your browser's local storage.
When you confirm your transaction on the Frontend, the DApp will generate a two-signature predicate transaction for each spended UTXO.
The real benefit of this application is that it supports spending multiple UTXOs with distinct predicate data.

š„ Second Prize ā Fuel Price Oracle
Fuel Price Oracle implements a simple ETH - DAI tokens price oracle. This project allows retrieving token prices from the outside world on the Fuel chain with a Sway smart contract.

š„ Third Prize ā Capitalist Pigs
Enter the world of Capitalist Pigs, a Gamify staking for fees in a DeFi project using a set of NFTs.
Check out their demo video below:
How does it work?
First of all, you begin by generating a burner wallet on the upper right corner of the DApp. To start playing, you need to claim aĀ Pig, a stakable collectible NFT asset. By staking it, you will earnĀ TrufflesĀ andĀ staking feesĀ represented byĀ Bacon. Truffles can be turned intoĀ Piglets. With those Piglets, you have 2 possibilities: you can either turn them into Pigs or delegate them to existing Pigs to increase their staking fee generation. And this is it, you're a Capitalist Pig! You can check in the lower right corner the evolution of your supply (Pigs, Piglets, Truffles, and Bacon).
Try it out nowĀ here.
