🆔 Anon Aadhaar 
What is Anon Aadhaar?

Anon Aadhaar is a protocol for proving ownership of an Aadhaar identity (Indian Residence ID) in a privacy-preserving manner. It lets users generate a ZK proof of their identity by only revealing the information they want to share (to an application).

Developers can use the AnonAadhaar SDK to integrate this into their applications to verify the identity of users without asking them to reveal more personal data than necessary. The proof generated can also be verified on EVM-based blockchains making Anon Aadhaar suitable for on-chain applications.

Here's a few things we'll consider while judging your project:
- Is there a meaningful problem being solved with Anon Aadhaar? Does the project have potential to solve a real problem in production?
- Was the project fully integrated on both the frontend and backend? Does the integration work end-to-end?
- Is the project introducing novel implementations or new tech?
- Is the project posing a creative solution to a problem? Is Anon Aadhaar being used in a new way?

**What is Garden Finance?**
[Garden](https://garden.finance/) is a super-fast native Bitcoin decentralized exchange. In the past six months, we've processed $790 million in volume on the mainnet. Garden strives to be the best option for exchanging Bitcoin with any asset in terms of speed, cost, UX, and liquidity depth. We aim to create a decentralized Bitcoin trading experience that rivals Centralized Exchanges.

**Why Bitcoin?**

Bitcoin has long been the dominant force in the cryptocurrency market, currently representing about 52% of the total market cap. While its utility has traditionally been limited compared to EVM-compatible assets—lacking features like yield farming, staking, or trading digital collectibles—Garden Finance bridges this gap. This integration brings Bitcoin's robust security and liquidity into the DeFi ecosystem, enabling faster transactions and lower costs.

**What is Garden SDK?**

[Garden SDK](https://docs.garden.finance/developers/sdk/quickstart) is your gateway to bringing Bitcoin to DeFi. It enables the native Bitcoin swap in your dream Dapp, opening up a world of possibilities. While our competitors take hours for bridging Bitcoin, we do it in under 10 minutes, with the fastest swap in just 30 seconds. This is not just about speed, it's about unlocking the potential of Bitcoin in the DeFi space.

As part of our grants program, we've set aside a pool of $ 350k. But that's not all. We can offer workspace in our Hyderabad office, mentorship, AWS, infrastructure costs, and even marketing ideas. We're here to support you every step of the way, from the initial idea to the final product launch.

Here are some criteria we’ll consider for judging an application:

- Does the project tackle a meaningful problem?
- Does the project have the potential to bring Bitcoin to DeFi?
- Does the project have the potential to gain an initial set of users today?
- Does the integration work end-to-end on mainnet?
