Hashi is an EVM Header Oracle Aggregator designed to facilitate a principled approach to cross-chain bridge security. The primary insight is that most bridge-related security incidents could have had a minimal impact if the systems relying on them had built in some redundancy. In other words, requiring messages to be validated by multiple independent mechanisms, rather than just one, is much more secure.

Hyperlane is the permissionless interoperability layer pioneering a modular security architecture that empowers developers to own and customize their security stack. With Hyperlane, anyone can bring interoperability anywhere, the interoperability layer purpose built for the modular blockchain world.
🥇Top prize - $4,000 - Best use of Permissionless Interoperability To qualify to win this prize you simply need to deploy Hyperlane on a new blockchain or Rollup. Once deployed, how you utilize your new-found interoperability capabilities will dictate how likely you are to win the grand prize! Could you be the first one to bring Hyperlane to Scroll? Or Fuel? What about other chains participating in the hack? You could even deploy to your own chain! Examples would include deploying to your own rollup created via Celestia, Optimism, Polygon, or any rollup toolkit you’d like to use! Permissionless Interoperability related submissions will be eligible for smaller prizes, such as the Warp Route or Scaling Infrastructure prizes 💸 $2,000 - Best use of Hyperlane Warp Routes Warp Routes are Hyperlane’s unique take on token bridging. They are unique and instanced expression of bridging as opposed to the traditional omnibus token bridge design. Each Warp Route can have its own security model, using Hyperlane’s Interchain Security Modules. Perhaps most importantly, Warp Routes are completely permissionless! No one can stop you from bringing whichever asset you’d like to any chain you’d like. So how can you win this prize? While the only strict requirement is that you use Warp Routes in your submission, the more creative you get with it the better! Here are some ideas about what you could do Create the first bridge to a new chain! This would also make you eligible for the grand prize 😉 Leverage Warp Route’d assets in an app of your design for a boost to an already strong submission Use Warp Routes to create interchain NFTs or bridge existing collections 🏗 $2,000 - Hyperlane Powered Scaling Infrastructure Use Hyperlane to navigate between networks and create scalability focused infrastructure! While there is no specific form these should take, here are some ideas we’ve thought about: Blockchain Smart Router. Imagine being able to route computation to the cheapest blockchain within the Hyperlane network, and then being able to retrieve or read that state whenever necessary from your home chain. Effectively turning any blockchain into your layer 2 and beyond. This will be incredibly challenging to build, but the rewards will be far greater than you can imagine! For NFTs, you could create an interchain minting contract that acts as a load balancer between chains, i.e collecting orders on several chains (with lower fees or higher throughput) and executing the mint on a different chain.

UMA is an optimistic oracle (OO) that can verify any statement proposed on the blockchain. Using economic incentives, the OO tells smart contracts “things about the world” so contracts and markets asking for that data can be settled. Across, UMA's sister project is a cross-chain bridge that supports cheap, secure, and near-instantaneous transfers between L2s and to L1. Across transfers are secured by UMA’s optimistic oracle. Builders can use OO as a decentralized truth machine that is flexible enough to handle ambiguity and real-world data with human-powered dispute resolution. UMA’s OO secures and empowers a diverse set of Web3 applications, including cross-chain bridges, insurance protocols, prediction markets and customizable DAO tooling products.
UMA's OO expands what can be built in Web3 and there are many use cases that haven't been thought of yet. We're looking for submissions that build new and innovative on-chain protocols that require off-chain, cross-chain, or aggregated data verified by our oracle.By hacking on Across you will help to strengthen and broaden the bridging ecosystem and increase adoption of L2s. To do this, we need projects that improve scalability, security, and simplicity — and help to provide solid bridging infrastructure that people use without hesitation. 🥇- $5,000 🥈 - $2,000 🏊♀️ - $3,000 pool prize

Fuel is the fastest execution layer for the modular blockchain stack. Powerful and sleek, the technology enables parallel transaction execution, empowering developers with the highest flexible throughput and maximum security required to scale. Developers choose the FuelVM for its superior developer experience and the ability to go beyond the limitations of the EVM.
Fuel Labs is giving away $7,000 USDC in bounties across three categories:
📄 Best smart contract written with Sway - Use Sway to write and deploy a unique smart contract and get a chance to win the “Best smart contract written with Sway” bounty.
🏗 Build A Fullstack Dapp on Fuel - We believe top teams perform best when they're building something they believe in and are passionate about. This bounty is open to teams who want to build a fullstack dapp (contract and frontend) using Sway and the TypeScript SDK, leveraging Fuel's unique properties like parallel transaction execution, account abstraction via predicates, shared global memory architecture, and more.
⚙️ Best Use of Predicates - Fuel has native account abstraction through predicates. A predicate is just a condition under which you can spend a UTXO. Predicates are scripts where the main function returns a boolean. A pure function where assets under that predicate are unlocked and can be spent by the caller if evaluated to true. A predicate owns or controls UTXOs, and with predicates you can build things like native multi sigs, atomic swaps, and more.

zkSync Era is a Layer 2 zkEVM designed to scale blockchains like the internet. With zkSync Era, it’s trivial for web3 developers to take advantage of high-speed, low-cost transactions with the same security guarantees as Ethereum.
zkSync Era also supports native Account Abstraction. By combining intuitive UX with self-custody, AA-enabled Smart Wallets are critical to onboard the first billion users to web3.
zkSync Era has arrived at the Fair Onboarding Alpha milestone, meaning the system is fully open source and registered projects can start to deploy on mainnet.
We’re also welcoming you — our passionate developer community — to start building on zkSync Era through one of the Bounty Tracks below.
TD;LR: Innovations in self custodial wallets for a better user experience and user interface (UX/UI), with lower fees, will help onboard the next billion users. In this track, you have the opportunity to use Account Abstraction which is implemented in the protocol level on zkSync Era.
🪄 The Magic: Account Abstraction unlocks innovations in wallet design by bringing web2 UX/UI convenience to web3, so that self custody is much easier and decentralization increases.
🤫 The Secret: Account Abstraction allows organizations to create curated web3 experiences to smoothen onboarding, security and retention. It’s the holy trinity of usability. With AA, we can adapt accounts to business logic needs, instead of adapting business logic needs to accounts.
🔍 The Deets: By treating smart contract accounts at the same level as Externally Owned Accounts (EOA), we can break free from the EOA’s hardcoded assumptions. Accounts are abstracted because now the implementation and the interface are decoupled, allowing for customizable accounts only limited by your imagination.
A great example of Account Abstraction can be found in Raise Finance’s Blog: https://raisefinance.medium.com/the-power-of-account-abstraction-technical-overview-of-the-raisepay-wallet-8e8c43dee64f.
TD;LR: Innovations in developer tooling to turbo charge productivity.
