Description

Defender Tooling
OpenZeppelin Defender is a security, automation, and operation Web3 platform, designed to enable projects to code, audit, deploy, monitor, and operate blockchain applications with confidence. We want to integrate and improve developer workflow for all teams, from small startups to established organizations. We have a few ideas that we think would benefit the entire ecosystem:

Deploy from Remix using Defender Deploy API
We know a lot of people start their Solidity journey on Remix, and even experienced developers use it to quickly prototype and test. To improve the developer experience, we want to allow projects to leverage the security and functionality of Defender Deploy directly from the Remix application.

The challenge for you is to build a Remix plugin that allows you to deploy smart contracts using Defender Deploy behind the scenes.

Seamless Multi-chain Deployments
As Ethereum scales through its wonderful and vibrant L2 community, some projects decide to deploy to multiple chains to leverage users and liquidity. Defender already makes this process easier by allowing you to manage your deployments as a whole using environments and support for deterministic deployments using CRATE2 to ensure a contract will be assigned to a specific address.

But there's still a struggle these projects face. If you want to deploy across multiple chains you have to fund the Relayer on each L2 and manage the funds yourself (besides having to run the script multiple times - one per each chain).

There are two things we would like to see you build (they are separate challenges, but bonus points if you manage to solve the two):

Multi-network Deploy
Allow users to deploy to multiple networks with a single API request. The idea is that the user specifies the networks he wants to deploy to and that the contract is deployed across those chains on the same address.
Defender Relayers Advanced Funds Management
Users often prefer to use our Relayers service to easily sign and submit on-chain transactions, also when deploying a contract. However, when deploying across multiple networks, users need to create, fund, and manage a Relayer per each network.

The challenge for you is making this process more seamless by managing the deployment and gas across multiple chains transparent to users by automatically swapping funds from one Relayer to another to pay for gas. This will allow users to deposit funds to a single Relayer and then use those funds to pay for gas to deploy their contracts to any supported network.

For these you will probably need to fork the defender-sdk, you can find the code here.

General Open Source Tooling
Above are two ideas that we strongly believe will benefit the entire community if built, but we know there are tons of other great things that can be built. So if you think you have a great idea for a plugin or other open source component that uses Defender we are looking forward to seeing it! Our only ask is that it must use Defender and preferably if it integrates with other tools they are widely adopted open source projects in the web3 ecosystem.

DeFi with Defender

Use Defender to automate or secure an existing or new DeFi application. You must highlight how you used the different Defender components inside your project. Some ideas and examples:

Monitor oracles (like TWAPs) to get alerts if they are being manipulated (for example, using deviation)
Create an action that automates a protocol operation per N blocks
Rebalance Uniswap positions automatically with Monitors and Actions
Create a Workflow that pauses a protocol if there's a lot of token outflows for hacks or suspicious activity
Arbitrage bots (like CEX/DEX arbitrage) with Monitor and Actions
Combine Relayers with Account Abstraction for interactions with DeFi protocols

Requirements

Use Defender and/or the Defender SDK, Defender as Code.
Your source code must be public on a GitHub repository

Judging Criteria

Technical Complexity and Innovation
How complex is the problem being addressed, and how sophisticated is the approach to solving it? How innovatively has Defender been used? How well did the team overcome technical challenges?

Originality and Creativity
Is the project tackling a new or unsolved problem, or does it create a unique and creative solution to an existing problem? How well did the team think outside the box and develop an original concept with Defender?

Functionality and Completeness
How complete and functional is the project within the given timeframe? Are the core features implemented and working as intended?

UX/DX/UI
Is the project intuitive and easy to use? How much effort did the team put into creating a user-friendly interface and removing friction points?

Impact and Potential
What is the project's potential to make a positive impact on the developer ecosystem on Scroll and Defender? How scalable and viable is the solution in the long-term? How effectively does it solve the identified problem?

Sindri

Title

Most unique uses of Sindri

Bounty Value

Total Value: $6,000 + Sindri Credits

Awards:

Top 3: $2K USD each + 10 hours of Sindri Credits
Teams 4 through 10: 5 hours of Sindri Credit for submissions

Quantity of Available Bounties

Description

Sindri is the ZK Developer Cloud providing builders with accessible, streamlined infrastructure often required for developing, deploying and scaling ZK. With the rise of zkML, offchain applications, rollups, and Layer 2s, teams are confronted with increasingly difficult infrastructure requirements, storage, and cloud configuration for building and deploying with ZK. Sindri abstracts away these complexities and overhead and turns your cloud builds into a few API calls.

Builders will find engaging with Sindri is very much like a Web2.0 developer experience. Similar to how a developer might interface with Infura or Stripe, Sindri is also integrated via API. This means you can build ZK infrastructure right into application or protocol logic or the browser front end. To make iteration even easier, we've integrated Sindri into Remix IDE.

The Sindri API offers out-of-the-box, serverless proving deployments, adaptable support for your favorite proving systems with minimal refactoring required, built-in acceleration, and SDK/CLI tooling to deliver a phenomenal developer experience mirroring to the CI/CD workflows you're already accustom to. Develop and deploy amazing ZK applications in minutes instead of weeks or months without the hassle of having to spin up, configure and maintain generic cloud resources.

We've built Sindri from a place that respects the builders and coders who need accessible, reliable infrastructure solutions to share their life work. We're excited to share it with you.

Requirements

Track agnostic, so long as the team meets the requirements outlined below:

A submission that leverages ZK and Sindri's API and versatility. Your project should utilize one of Sindri's supported proving systems, including Gnark, Noir, Halo2 (Axiom), and Circom, to build something truly unique. zkML, coprocessors, AI agents, interoperability solutions, payment gateways, DePIN, and more have all leveraged Sindri.
Our Python, Javascript, and Typescript SDKs and tooling allow you to build proving logic directly into the application layer, streamlining access to Sindri's scalable, accelerated infrastructure stack. In turn, developers can build with large circuit structures and unexpected, high-volume request spikes, which are often challenging in ZK applications.

Circom + Python + Sudoku
Gnark + Javascript + String Compression
Halo2 + Rust + Floating Point Arithmetic
Noir + Javascript + PageRank

Judging Criteria

New projects only, please (one submission per prize category; it's okay to use pre-written open-source components, but specify what is original to this project)
Must have Sindri integrated into the submission
Must leverage Sindri for proof generation
Ability to support multiple or concurrent proof request environments preferred (e.g., end users requesting proofs at scale, scheduled proof generation, etc)
