zkSync: 👛 Wallet Logic!

Description 📃

For first timers:

If this is your first time at a hackathon or with your teammates, this blog post on organizing a hackathon team may be beneficial(https://tesla809.medium.com/draft-crash-course-how-to-organize-a-hackathon-team-29b221c23905). In our experience, a clear method of collaboration increases the chances of teams completing their projects, improves team efficiency, and reduces the time to completion.

TD;LR: Innovations in wallet design for better UX/UI, plus lower fees, will help onboard the next billion users. Because good UX/UI like is magic. It just works.

✨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 create smooth onboarding. 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

Dapp suggestions:

Think of your own idea! Optionally, you can pick one of a few of the hackathon idea suggestions as prompts to user stories via the following categories:

• Security to increase safety and self custody for users

• Onboarding to attract users and simplify interactions, reduced number of steps, or clicks.

• Retention to keep them

Improve security using Account Abstraction via one or more of these:

• One idea is a general abstraction in multisig wallets for plug and play services: easily add fraud monitoring, KYC, or any arbitrary service.

• This general abstraction can be used for multi-factor authentication via any medium: Gmail, Google Auth, etc.

• Another application could be fraud monitoring or KYC service, where the service is one of the multi-sigs wallet signers: if configurable compliance rules work, sign. For example, if transactions are under a certain amount or accounts are not on OFAC list.

• Another idea is a general purpose custom wallet generator: easy to create inter-linked custom accounts customizable functionality, using visual GUI tools. Think IFTT meets ETH.Build, meets Your Favorite Wallet.

• An application would be the easy generation of compliant intra-web of accounts for organizations. This allows the segregation of funds and easier control of risk. Some accounts can only pay certain vendors, employee payroll, investments only in certain assets, taking deposits, etc. How can you map the payment flows of an organization to an intra-web of accounts?

• We’d love to see any cool and innovative ideas you can dream of.

• Some prompts to get your imagination going are: Deadman switches, interesting forms of social recovery, Emergency Escape Hatches from L2 → L1, Innovative Curve and Encryption Schemes, customizable allow / deny lists for DApps, social methods of crowdsourcing allow / deny lists, trading margin limits based on number of multi-signature signers, easy methods to generate new accounts based on DApps, safety vaults for safe storage like customizable time locks on certain assets to prevent stealing.

Improve onboarding using Account Abstraction and Paymasters via one or more of these:

• paying the gas fees for users with Paymasters.

• paying bills and fees with ERC20 tokens like USDC.

• session keys: easily generate sessions keys to approve all transactions under certain customizable conditions. Super useful for gaming or immersive experiences.

• multi-calls: no more signing several transactions, now you can batch transactions for flow.

• Any out-of-the-box ideas you can dream of. Impress the world!

Improve retention via one or more of these:

• Using Paymasters to reward on-chain activity like: pay fees or percentage of fees for users that meet a certain threshold.

• Using Account Abstraction to help increase utility of assets.

Acceptance Criteria 🏁

First, the DApp MVP must work. Whatever is claimed to work, must work. If not, cut the feature.

• Documentation should include**:**

  • a clear README.md with the following:

    • a clear short one-sentence description of your dapp. Aim for something simple like: “Easy social recovery via Telegram” or “Customizable long-term vaults on smart contract accounts to prevent thefts from hacking”.

    • short description of team and backgrounds.

    • a clear installation/execution process that works.

  • a clear Open Source License: MIT, GNU, Unlicensed or any standard open source license your team want.

  • a simple UML to describe how the contracts interact with each other.

  • a clear 2-4 minute video demo walking through the DApp.

  • Have a Project Description section: with a longer written description of what the project does.

  • How its made section: Describe how you made the project, mention any issues you ran into.

  • Please show a steady commit trail and thought process e.g. sketches, discussion, issues on how you arrived at the decision to incorporate this feature.

Code:

• Your Solidity/Vyper code must use NatSpec.

• Bonus points for:

  • Producing a tutorial we can use

  • scripts to automate installation with ease

  • an additional ~2-5 minute video talking about the code. Geek out and show us your skills.

  • Great UX/UI

  • a slide presentation in README.md

  • JSDocs comments for JavaScript or TypeScript code

  • A catchy name and logo

  • a clear Design Statement using the format: How might we improve (a problem in the domain)_____ for (user), so that (user-focused outcome)___?

  • For an example: https://tesla809.medium.com/draft-crash-course-how-to-organize-a-hackathon-team-29b221c23905

  • Having tests or fuzzing.

zkBob: zkBob Bounty

Description 📃

Integrate BOB stablecoin and zkBob Direct Deposits functionality into your application. Demonstrate how your app users can benefit from optional transactional privacy with zkBob.

BOB is a decentralized stablecoin with opt-in anonymity and confidentiality features powered by a protocol based on zk-SNARKs. One of the disadvantages of these types of protocols is the sender needs to calculate a proof using their secret key each time, making it difficult to use a smart contract to automate such payments. We've done our best to eliminate this problem by introducing the Direct Deposit feature. You can now send funds to anyone in the privacy pool directly from the smart contract. This feature makes the zkBob protocol much more composable and suitable for integration where funds transfer can be included as a subroutine to other decentralized protocols. See more details in the documentation.

Some ideas (we'd ❤️ to see any other novel use cases) to start brainstorming from:

- Integration within open-source wallets

- Apps for DAO accounting

- Browser extension for zkBob

- Donation/fundraising/tipping apps

- Privacy for P2P micro-transactions

- Integration with DEXs/bridges/aggregators

Bounty

1st prize - 5,000 BOB

2nd prize - 2,000 BOB

Notable projects: pool of 3,000 BOB will be evenly distributed among all other notable submissions

Acceptance Criteria 🏁

- Creativity, novelty, usefulness for end users and implementation quality.

- Importance of zkBob integration to the overall application/product (i.e. is it integral to app functionality, usefulness and purpose or is it an add-on without a lot of added value).

- Coherent integrations between zkBob and other existing protocols/dApps are appreciated

- Alignment with the BOB and zkBob ecosystem values of on-chain privacy protection within accepted limits.

- *extra credit will apply to solutions using other zkBob components on top of integration with direct deposits (zkBob SDK libraries, gift cards, compliance tooling, deep smart contract integrations, etc.)

RISC Zero: Build on RISC Zero or Integrate RISC Zero into your project

Description 📃

We are offering a total of 5 prizes, with a top prize of 7,000 USDC and a minimum prize of 2,000 USDC to qualifying projects.

We reserve the right to withhold prizing in cases where low-quality submissions do not meet our bounty requirements.

RISC Zero’s core technology is our RISC-V Zero Knowledge Virtual Machine (https://github.com/risc0/risc0). On top of that, we’re building a zero knowledge computing platform called Bonsai. Bonsai supports the ability to do arbitrarily complex computations in plain Rust and access proofs of those computations on-chain, effectively adding Rust support and Zero Knowledge scaling to Layer 1 Ethereum.

Bonsai is currently in a pre-release stage and, as part of this bounty, we’d like you to build an application using Bonsai. Doing so requires getting early access, which you can request here. However, even prior to getting access, you can participate in this bounty.

To build such an application, you’ll need two major components: your application logic written in the form of zkVM guest code and a solidity contract as an interface to the Ethereum world. Communication between those two components will happen via the Ethereum Bonsai bridge.

Because Bonsai is in a pre-release state, we expect you to need some help getting going - to support this, we’ll have Bonsai developers available to help via discord (and a few in person, as well).

For application ideas, think about computationally intensive tasks. What have you always wanted to see on Ethereum but development complexity or gas costs/caps have kept you from building?

Acceptance Criteria 🏁

We’ll be looking for projects that demonstrate why a generic zero knowledge compute platform is so interesting. This means that porting an existing Solidity application to Bonsai is probably not a good strategy. We will be judging submissions based on utility, novelty, and quality. Partially finished submissions will be considered for awards.

Spectral Finance: Spectral.finance's Bounty

Description 📃

It’s Buidl season with Spectral Finance!

We’re excited to welcome Web2 + Web3 developers alike, to our growing ecosystem through #BuidlWeek at ETHDenver.

Prompt: Build a dApp that integrates Spectral’s MACRO score in a way that brings value to an existing Web3 protocol, or that can create new value through a novel implementation (ex. hybrid lending systems, identity tools for MACRO Score, etc.).

Launch MVP on Abritrum Goerli. We’re looking for innovative solutions that encourage collaboration. Such as tools to bridge the gap between, traditional FinTech and Web3, credit analysis; projects that utilize the MACRO Score to enable end-to-end capital efficiency or that enables new ways of lending on-chain.

Examples include (*but are not limited to*):

1. A lending protocol that uses Spectral’s MACRO Score (on-chain credit score) to 1. adjust interest/collateral rates 2. OR create an entirely new model for lending (eg. imagine Uniswap v3 but for lenders)

2. A gating mechanism for protocol usage. Gates can be ranges of the score (eg. imagine a low-risk lending facility only serving users with scores 700-850)

3. A protocol that does not reveal a user’s score on-chain (using zero-knowledge proofs or other tools) and adjusts behavior with users in an obfuscated manner. (eg. User A interacts with Protocol 1 → Protocol 1 wants to know how credible User A is. How do we prove to Protocol 1 what User A’s score is without revealing the score to Protocol 1.)

Acceptance Criteria 🏁

- Vision and use case

- Live and usable MVP on Abritrum Goerli

- Video demo of a live application

- Open Source code: e.g. MIT, BSD, GNU

- Great documentation in code and a well-explained **README**.

- Please show a **steady commit trail** and thought process e.g. sketches, discussion, and issues on how you arrived at the decision to incorporate this feature.

- List any **challenges or benefits** you encountered in the developer experience.

- Overall Value Proposition (any of the following):

- Improves capital efficiency of lenders and borrowers in DeFi protocols.

- Improves the functionality of Web3 protocols.

- Implementation of MACRO score in an application creates value in novel ways.

- Creation of a tool that improves the MACRO Score. - User Experience - Creativity

Tenderly: Tenderly Simulation API Integration

Description 📃

Build a dapp that integrates Tenderly Simulations. Simulate a transaction and use the simulation result to determine if the transaction should be sent to the chain or discarded if it fails or results in undesired ways.

The goal is to use simulations to:

- minimize the occurrence of failed transactions and
- avoid transactions with undesired results from the user’s point of view.

**Approach:** You can use Simulations in several ways:

- Build a UI that lets users decide if the transaction should be sent to the chain, based on simulation results shown to the users.
- Build a programmatic decision-making process that automatically discards transactions that don’t fit the criteria specific to your dapp (e.g. swap can be better), and informs the users about it

**Integration:** You can integrate Tenderly Simulations in two ways:

- Using the tenderly_simulateTransaction JSON RPC call included with Web3 Gateway
- Using the REST Simulation API

3 winning projects will win 2000$ in USDC each!

Acceptance Criteria 🏁

## Option 1: Enable users to discard undesired transactions in dapp UI

- Build a UI that shows relevant information about transaction execution (state changes, tokens swapped, changes to balances, or information derived from that, etc). The information should help the user decide if they want to send a transaction to the chain or discard it.
- Build a UI that enables users to approve sending the transaction to the chain or discard it after seeing the additional information (above).
- Demonstrate reduction of failed transactions: Provide an example of a failing transaction, whose failure is avoided by your solution (either a transaction object in README or video of building it through the UI).
- Demonstrate reduction of undesired transactions: Provide an example of a transaction that has suboptimal results, such that the user decides to discard it (either a transaction object in README or video of building it through the UI).
- [nice to have]: Build a mechanism to calculate and display suggestions for transaction inputs, so that transaction gets desirable results.

## Option 2: Automatically discard undesired transactions

- Provide written criteria for desirable transactions in the project’s README.
- Programmatically discard transactions with undesirable effects, according to criteria specific to your dapp.
- Inform the users that the transaction is automatically rejected, showing information about what led to the rejection.
- Provide an example of a failing (reverting) transaction, whose failure is avoided by your solution.
- Provide an example of a succeeding but undesirable transaction that gets automatically discarded (either transaction object in README or video of building it through the UI).
- [nice to have] Build a mechanism to calculate and display suggestions for transaction inputs, so that transaction gets desirable results.
