Gnosis Chain will be awarding the following prizes for use of Gnosis Chain:

Most innovative dApps on Gnosis Chain:

• 🥇 Gold Prize: $8,000
• 🚀 Silver prize: $5,000
• 🤝 Bronze prizes: $3,000
• 🌉 Best project on Hashi: $2000
• 🌉 Best project on Safe: $2000

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.

Learn more about Hashi here: https://github.com/gnosis/hashi

With the advent of Account Abstraction (AA), a new world of possibilities has opened up. One of its most notable advantages is the ability to execute "sponsored transactions," which are covered by a third party rather than the user. To take advantage of this feature, we have teamed up with Safe to sponsor all transactions carried out using Safe on Gnosis Chain. This makes it possible for developers to create gasless experiences that feel like web2 interactions.

We are offering a $2,000 bounty to the best project utilizing the Safe{Core} Account Abstraction stack on Gnosis Chain. Be sure to also check out Safe's designated ETHGlobal Tokyo bounty for further resources and instructions

Best Dapps 👷

Build a DeFi, NFT, identity, social, or gaming dapp – or anything you are passionate about. Just build the dapps you love, scale Ethereum, and make it more accessible for people around the world. Remember: you can build on Taiko exactly as you would on Ethereum!

🥇 $3,000

🥈 $2,000

🥉 $1,000

Infrastructure Improvements 🧱

We "operate" Taiko just like the Ethereum Foundation "operates" Ethereum, where the open source codebase is the deliverable that we offer to the community, not some for-profit service. That’s your chance to make Taiko’s ZK-Rollup infrastructure to make it more usable and convenient.

🥇 $2,500

🥈 $1,000

Ideas to consider:

• NFT bridge (learn more about our signal service: https://taiko.xyz/docs/concepts/bridging/the-signal-service)
• https://github.com/taikoxyz/taiko-mono/tree/main/packages/protocol/contracts/bridge
• ZK additions to blockscout explorer, such as visualising the blocks proving/verifying process
• GUI or set-up wizard to help anyone run a rollup node (with add-ons for proposer & prover).

Catch MEEEEEEEEEV! 🤖

MEV is everywhere. Even where you think there is no MEV – there is MEV. And of course Layer 2 is no exception, L2 transactions are a source of MEV! Whatever you come up with to catch, auction, or direct MEV on Taiko L2 will be useful here. And since we are Ethereum-equivalent, the existing MEV tooling and infrastructure on Ethereum L1 is reusable on Taiko.

🥇 $2,500

🥈 $1,000

Ideas to consider:

• Integrate flashbots into Taiko proposers.
• Improve block proposing mechanism (ex. take into account calldata cost)
• Craft a kind of “mev-boost” for Taiko L2
• Integrate fancy shared sequencers (Taiko supports those out of the box)

ZK-Zone 🥷

The core of the Taiko ZK-EVM are the ZK-EVM circuits! And the rollup makes use of ZKPs elsewhere as well. Sharpen your circuit writing skills and help improve Taiko while doing so.

🥇 $2,500

🥈 $1,000

Ideas to consider:

Improve the efficiency of bridging on L2 by replacing the (standard!) Ethereum Patricia Merkle Proof checks in the bridging smart contract by a zero knowledge proof verification that verifies the Merkle proofs in a circuit. This exchanges data costs (higher on L2) for computation costs (lower on L2).

Protocol Economics (no-code bounty!) 🤓

Help us to design the Taiko Protocol Economics to make it solid, reliable, and robust. No formal rules or constraints, just be creative and think out of the box. Keep in mind that Taiko has decentralized both proposers and provers, for more details about the protocol design check this workshop.

🥇$1,000

Ideas to consider:

There are two aspects of the tokenomics. 1) the tokenomics between proposers and provers with the protocol mediating it, 2) the proposers need to buy L2 block space through EIP-1559 or similar mechanism. How may one change EIP-1559 to adapt to the fact that L2 blocks do not have constant intervals (block times).

🥇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 - Write new Interchain Security Modules (ISMs) Hyperlane’s Modular Security Stack is premised on a variety of available Interchain Security Modules that developers can use to secure how applications can communicate between chains. While a few ISM’s are already available, and more are in the works, the hackathon is a great opportunity to build new ones. Some suggestions for ISMs Hyperlane developers would like to see: An Optimistic ISM; this would implement an ISM that secures messages with an Optimistic system, in the mold of the Optics protocol, one that allows for a challenge period of some time, during which a fraud proof can be submitted by anyone. A successful submission will include the ISM itself, and any necessary offchain agent software such as the Watchtower and any Relayer changes. A Telepathy ISM; the newly released Telepathy client allows for interchain messaging from Ethereum secured by ZK-SNARKs. A Telepathy ISM would use the Telepathy client to secure outbound messages from Ethereum. A successful submission will include the ISM itself, and any necessary changes to the Relayer. A Native/Rollup Bridge ISM; this ISM would leverage the native bridge for a rollup, i.e. the native Optimism or Arbitrum bridges, to secure messaging. A successful submission will include the ISM itself, and any necessary changes to the Relayer.

Safe will be giving $10,000 for the best hacks using Safe {Core}. To be eligible, developers must use at least one of the Safe {Core} Account Abstraction SDK kits listed below.

🧰 Protocol Kit

The Protocol Kit uses the Safe Core SDK to interact with Safe contracts using a Javascript interface. This SDK can be used to create new Safe accounts, update the configuration of existing Safes, and propose and execute transactions.

✅ Auth Kit

The Auth kit creates an Ethereum address and authenticates a blockchain account using an email address, social media account, or traditional crypto wallets like Metamask.

💳 Onramp Kit

The Onramp kit allows users to buy cryptocurrencies using a credit card and other payment options.

🏃🏻‍♀️ Relay Kit

The Relay Kit allows users to pay transaction fees (gas fees) using the native blockchain token or ERC-20 tokens. This allows you to pay gas fees using any ERC-20 token in your Safe, even if you don't have ETH.

Other Account Abstraction bounties

If you are planning to hack on Safe{Core}, make sure to also check out some of the other bounties as your hack may qualify for them as well:

• ZK Proofs: Utilize ZK proofs for critical vulnerabilities while not disclosing the vulnerability, i.e. prove there’s a vulnerability to the DAO so they can vote on it informed but not actually say what the vulnerability is.

• Health Factor Simulator: Build a UI component that displays a price slider per each collateral and borrowed asset, so you can simulate prices and see how your Health Factor changes under those conditions. Allowing you to take informed decisions to mitigate liquidation risks.

• Debt Swap: Right now you can swap your collateral from one asset to another but imagine if you built a new feature for swapping debt from one asset to another.

Be sure you do not expose private keys or other sensitive information through hardcoding or pushing .env files. Make sure your code is well documented on GitHub and preferably has a front end that is available to be used on a public website. If you created smart contracts, deploy them to a testnet and ensure your front end properly interacts with them.

Quantstamp was recently awarded three Ethereum Foundation grants related to rollups. For this hackathon, we will award our prize(s) to projects that are related to rollup security, compression, or block explorer APIs. The winning project should choose one of these topics and explore questions related to it; the winning project should produce some artifacts that explain, expand, or experiment with related ideas. Some ideas might include:

• Documenting how a rollup operator can upgrade contracts quickly or sneakily.

You could deploy Optimism on a testnet, and try to upgrade their contracts. During this process, are pending transactions affected? Why or why not? Can you replace your contract with anything? Are there difficulties that you, as the operator, face during this process?

• How much more (in-)effective would it be to use a particular compression algorithm for calldata on a rollup?

You could evaluate changing the compression algorithm for an open-source rollup’s calldata. You could swap out the compression algorithm for another, and evaluate if it performs better or worse.

• What data would you like to see on a ZK rollup block explorer that might not exist on Etherscan, and how would that data be presented?

You could mock up a Layer 2 block explorer of your dreams, paying special attention to features unique to zero knowledge rollups.
