<h2 id="objective">Objective:</h2>
<p>A one-stop testnet faucet for all the substrate chains that will also support EVMs on substrate chains making it the first <strong>Hybrid Faucet</strong> in the ecosystem. With XCM channels exploding already, we should presume the upcoming wave of next-gen Polkadot dApps is near! Most of them will leverage multiple parachains and solochains simultaneously. To cater to this future need we are introducing this universal faucet idea with single-click multi-chain disbursements to make cross-chain testing a breeze.</p>
<h2 id="features">Features:</h2>
<h4 id="faucetwith2modes">Faucet with 2 modes:</h4>
<p>﹒ <strong>Network switcher mode</strong>: This can be utilized for individual disbursement on a specific substrate chain.</p>
<p>﹒ <strong>Network selector mode</strong>: This can be utilized for bulk disbursements on selected substrate chains.</p>
<h4 id="evmsupport">EVM support:</h4>
<p>All frontier-based EVMs will be supported right out of the box. While support for custom EVM implementations will be added on a rolling basis.</p>
<h4 id="attackresilient">Attack Resilient:</h4>
<p>The Faucet will be immune to attacks using derived accounts. Also using web3/signer login, the faucet can be used only once a day across all the accounts from the signer.</p>
<h2 id="costandtimeline">Cost and Timeline:</h2>
<p>We are considering $500 per chain integration with 50% of the grant being vested for 1yr (vesting will be done in the same multisig with the contributors as signers). There are currently 69 testnets in the Polkadot ecosystem. Referencing the EMA30 which is <strong>$7.716 per DOT</strong> the total will be <strong>4471 $DOT</strong> which is ~34500$. The complete development will be done within <strong>4 weeks</strong> with the additional service of maintaining the faucet for 24 months along with weekly integration for new testnets at no additional costs.</p>
<h2 id="futurescope">Future scope:</h2>
<p>﹒ Support for Mainnets and further improvements based on the community&rsquo;s feedback and suggestions.</p>
<p>﹒ We can also implement social login if required.</p>
<p>﹒ In-app integration with interfaces(like PolkadotApps) and wallets.</p>
<h2 id="aboutus">About Us:</h2>
<p>We are a collective of experienced contributors from EdgewareDAO looking to start the contribution journey in Polkadot with this small project.</p>

<h2 id="qas">Q&amp;As:</h2>
<h4 id="whydoweneedauniversaltestnetfaucet">Why do we need a universal testnet faucet?</h4>
<p>The universal testnet faucet is quite crucial for developers who are looking to leverage technologies from different substrate chains in their stack. This will also complement the push towards multichain hybrid deployments.</p>
<h4 id="howisitdifferentfromotherfaucets">How is it different from other faucets?</h4>
<p>Currently, we don&rsquo;t have a faucet that does single-click multi-chain disbursements in the whole substrate ecosystem. The ecosystem also doesn't have any ready-to-use faucet which supports all the testnets.</p>

Universal Hybrid Substrate Faucet

<h1 id="tldr"><strong>TL;DR</strong></h1>
<p>This is the first edition of a series aiming to build a developer community in India for the Polkadot ecosystem from the ground up by hosting in-campus workshops and hackathons in the leading <a href="https://en.wikipedia.org/wiki/Indian_Institutes_of_Technology">IIT universities</a>, which are known worldwide for producing the largest number of leading developers. IITs have a vast untapped talent pool that needs to be curated through a well-defined path of learning, knowledge exchange, and a competition. We are looking to establish the path through this 3-in-1 event, which features workshops for accelerated learning, the foundation of students' collective for a series of tech &amp; non-tech activities, and the final hackathon.</p>
<p>&nbsp;</p>
<h1 id="whynoteventsbounty"><strong>Why not events bounty?</strong></h1>
<p>We did apply for the events bounty twice, but the curators denied our initial and refined proposals because of reasons mentioned, like a limit on the number of organizing members involved, their misunderstanding of the review rating with a star rating for one of the cheapest accommodations, etc. We will post a detailed thread on our experience with the events bounty, especially the curators&rsquo; lack of thorough research later as our priority is the successful hosting of this 3-in-1 event in one of the best universities for which getting another approval (letter of intent) won&rsquo;t be easy.</p>
<p>Due to the two-week delay caused by the events bounty, we are forced to post multiple big tippers, as a small spender could take significant time. We need about 15k USD out of our total requested amount to make the necessary reservations/bookings (partial token amount wherever possible). So we are looking to post four big tippers and one small spender for the same. Upon approval of the first big tipper, we will encode the rest of the proposals and proceed with the bookings.</p>
<p>&nbsp;</p>
<h1 id="overview"><strong>Overview</strong></h1>
<p>We are excited to propose a first-of-its-kind hackathon and workshop for the Polkadot ecosystem in India, organized by <a href="https://blockseblock.com/"><strong>Blockseblock</strong></a> in collaboration with Edgetributors SubDAO. This event aims to foster innovation, development, and community engagement within the Polkadot ecosystem by bringing together talented developers, students, and blockchain enthusiasts. The fundamental propositions of this event are as follows:</p>
<ul>
<li>Hybrid structure: We will host the workshop and the hackathon two weeks apart, giving students time to review all the materials and the learning curve. Throughout this two-week period, we will guide/assist them virtually by forming a students&rsquo; collective.</li>
<li>Importance of IITs: IITs are often referred to as talent hubs in India due to their challenging entrance barrier for students and for well-known student activities like fests, workshops, hackathons, etc. Hosting this hybrid event in an IIT will attract enthusiastic students from the nearby universities as well.</li>
<li>Blockseblock's prior hackathon hosting experience, along with the technical curation/expertise of Edgetributors SubDAO contributors, will ensure that the event is not only successful but also impactful.</li>
<li>Being the first of this kind of collaboration, we focus on keeping this event budget-friendly yet accessible for everyone. We will implement our learnings in future hackathons across different IITs.</li>
</ul>
<p>&nbsp;</p>
<h1 id="problem"><strong>Problem:</strong></h1>
<p><strong>Limited Developer Awareness:</strong> There's a significant lack of awareness about PolkadotSDK and Substrate within the Indian developer community.</p>
<p><strong>Ineffective Meetups:</strong> Standard meetups often fail to capture the attention of developers from India's crowded IT sector.</p>
<p><strong>Tech Exposure Gaps:</strong> For Indian engineering students, significant-tech exposure typically occurs only within their universities or nearby IITs.</p>
<p><strong>Campus Placement Culture:</strong> The prevalent campus placement culture in India means students often only explore opportunities with companies that visit their campuses, missing out on the vast opportunities offered by Web3.</p>
<p><strong>Lagging Behind Competitors:</strong> The Polkadot ecosystem lags behind competitors in hosting student-specific learning events like workshops in the Indian demographic.</p>
<p>&nbsp;</p>
<h1 id="solutions"><strong>Solutions:</strong></h1>
<p><strong>Hackathon at a Leading IIT:</strong> Organize a high-impact hackathon at a top IIT to attract and engage talented developers.</p>
<p><strong>Pre-Hackathon Workshops:</strong> Conduct workshops before the hackathon to build foundational knowledge and excitement around PolkadotSDK/Substrate.</p>
<p><strong>Formation of a Students' Collective:</strong> Establish a students' collective to foster continuous engagement, collaboration, and learning within the Polkadot ecosystem. This will be crucial to the team formation and other activities after hosting the workshops, before the start of the hackathon.</p>
<p>&nbsp;</p>
<h2 id="whatssuccess"><strong>What's success?</strong></h2>
<ul>
<li>We expect 100-150 participants for the Workshops and Hackathon with at least 20-30 quality project submissions.</li>
<li>Formation of the collective that can feature the Polkadot Ecosystem in the IIT Roorkee, acting as a self-sustainable incubator/space for the new age developers.</li>
<li>This hybrid event aims at enhancing the visibility of the Polkadot ecosystem from the foundational level by cultivating more developers which will contribute to the natural growth and demand.</li>

Polkadot India IIT Roorkee Workshops and Hackathon (1/5)

<h1 id="overview"><strong>Overview</strong></h1>
<p>The <strong>@noble/curves</strong> package is a highly secure and thoroughly audited JavaScript library designed for elliptic curve cryptography (ECC). As a part of the noble cryptography suite, this package emphasizes security, minimalism, and ease of audit, all while maintaining zero or minimal dependencies. Its streamlined design and comprehensive feature set make it an ideal choice for a wide array of cryptographic applications, such as secure messaging, digital signatures, and key exchange protocols.</p>
<p>With its focus on robust security, straightforward auditability, and high performance, the <strong>@noble/curves</strong> package stands as a reliable solution for modern web and mobile applications that require strong cryptographic operations.</p>
<p>&nbsp;</p>
<h2 id="aboutpaulmiller"><strong>About Paul Miller</strong></h2>
<p><a href="https://github.com/paulmillr">Paul</a> is the founding developer behind <strong>@noble packages</strong> which are used by different web3 ecosystems. He is well known for his contributions via <a href="https://github.com/paulmillr/noble-curves">@noble/curves</a> and <a href="https://github.com/paulmillr/noble-hashes">@noble/hashes</a> packages which are directly/indirectly being used by the majority of the modern web3 protocols/toolings/platforms which includes even the forum you&rsquo;re currently reading this proposal on!</p>
<p>&nbsp;</p>
<h1 id="importance"><strong>Importance</strong></h1>
<p>The Polkadot ecosystem currently lacks a well-maintained and audited <strong>sr25519</strong> npm package in a pure JavaScript/TypeScript implementation. While the <strong>@noble/ed25519</strong> package is already available and utilized by Polkadot-JS over <strong>@polkadot/wasm-crypto</strong> for handling BigInt operations, there is no equivalent for <strong>sr25519</strong>. This gap presents a challenge for developers who require a reliable and efficient way to work with <strong>sr25519</strong> in native JS/TS within the Polkadot ecosystem, particularly when dealing with large numbers that exceed JavaScript's standard Number primitive. Filling this gap with a properly maintained package would enhance developer reach and flexibility across the ecosystem.</p>
<p>&nbsp;</p>
<h1 id="impact"><strong>Impact</strong></h1>
<h3 id="developertoolingbenefits"><strong>Developer Tooling Benefits:</strong></h3>
<ul>
<li><strong>Enhanced Simplicity:</strong> The <strong>@noble/curves</strong> package offers a straightforward solution for developers using JavaScript, TypeScript, React, and Next.js, making it easier to work with the native <strong>sr25519</strong> package.</li>
<li><strong>Advanced BigInt Handling:</strong> Developers gain the ability to handle BigInt operations more effectively, overcoming limitations posed by the <strong>@polkadot/wasm-crypto</strong> package, which relies on Rust libraries in a WebAssembly wrapper.</li>
<li><strong>Increased Security:</strong> The adoption of alternative implementations like <strong>@noble/curves</strong> will help mitigate the risks associated with dependence on a single package in case of zero-day exploits, acting as an additional layer for ecosystem-wide security.</li>
</ul>
<h3 id="marketingbenefits"><strong>Marketing Benefits:</strong></h3>
<ul>
<li><strong>Reputational Boost:</strong> By integrating with a widely-used library, the Polkadot ecosystem can enhance its reputation within the broader developer community also <a href="https://paulmillr.com/noble/">getting featured by Paul</a> for sponsoring the development/auditing which puts out a good precedent for the ecosystem.</li>
<li><strong>Increased Visibility:</strong> As many developers already use the <strong>@noble/curves package</strong>, this collaboration could attract more attention to the Polkadot community, particularly among developers who may not yet be familiar with Polkadot's capabilities.</li>
</ul>
<h2 id="edgetributorsubdaosrole"><strong>Edgetributor SubDAO&rsquo;s role</strong></h2>
<p>We came across the noble packages while preparing for our next project. We found that there is the ed25519 package which can be used with some patchy ways for our implementation. Then we came across the discussion on a <a href="https://github.com/paulmillr/noble-curves/issues/68">closed issue by ntn-x2</a> where Paul showed interest in the integration of the sr25519 curve, subject to sponsorship availability. So we followed up with him and he wanted to pursue this further. Considering the impact of Paul&rsquo;s work on the whole web3 space, we decided to voluntarily curate his proposal and take care of all the administrative work (as per his request). The entire amount corresponding to this proposal and the audit sponsorship proposal (yet to be proposed) will go to him and the auditing entity. In this whole process, Edgetributor SubDAO or Edgeware DAO or any Edgeware contributors are not getting financially benefited by any means.</p>
<p>&nbsp;</p>
<h1 id="budgetandtimeline"><strong>Budget and Timeline</strong></h1>
<p><strong>Budget distribution:</strong></p>
<ul>
<li>Part a (sign, verify, Point, pubkey) would take up to 1 working week, costing a maximum of 10000 USD for implementation. It could have been smaller, but it uses Merlin, which further utilizes Strobe.</li>
<li>Part b (hdkd, <del>musig,</del> vrf) would take up to 1 working week, thus the implementation would cost a maximum of <del>10000</del> 8000 USD. {Depending upon the viability, we might have a separate <a href="https://paulmillr.com/noble/#scure">@scure</a>/sr25519 package for the <del>musig and/or</del> vrf instead of including <del>them</del> it under @noble/curves/sr25519.}</li>
</ul>
<p><strong>Notable terms:</strong></p>
<ul>
<li>If the development finishes earlier than 2 work weeks, the corresponding unused funds will be returned.</li>
<li>Paul suggested the Cure53 auditing firm which doesn&rsquo;t need any upfront payment. He received the all-included quotation of 22500 EUR for a maximum total of 18 working days.</li>
<li>However, Cure53 is booked until January. So he is open to getting the auditing done through any other auditing firms. We are already discussing this with an auditing firm having an earlier availability. If anyone from the community knows of any auditing firms available within 1-2 months, feel free to suggest them in the comments.</li>
<li>For now, this proposal will be proposed for only the development of the @noble/curves/sr25519 package and another proposal can be proposed for the auditing after the development.</li>
<li>Paul requested payment through Github Sponsorships. For the same, we will buy 8-10 prepaid Visa/Mastercard cards using USDT which will incur 4-10% fees. We will share proof of the prepaid cards&rsquo; purchases and the unused fee buffer amount for the fiat conversion will be returned to the treasury.</li>
</ul>
<p>Requested amount: <del>20000</del> 18000 USD</p>
<p>Fee buffer amount for fiat conversion(10%): <del>2000</del> 1800 USD {unused amount will be refunded to the treasury}<br /><br /><strong>Total:</strong> <del>22000</del> 19800 USDT</p>
<p><strong>Multisig:</strong> 14XNJmoUzkvmh9cYoqG4axBRR4BWzWRbnFP79oiZgKu7V9bz</p>
<p><br /><strong>Changelog:</strong></p>
<p>Jeff Burdges suggested removing MuSig, considering its near-to-no adoption across the ecosystem. He also suggested supporting the <a href="https://github.com/w3f/schnorrkel/pull/110">upcoming OLAF protocol</a>, which can be done through a separate proposal as it is currently in the WIP phase. The proposal has been updated as per the new estimation by Paul Miller after removing the MuSig from the development scope. Huge thanks to Shawn Tabrizi for the feedback on <a href="https://x.com/TheKusamarian/status/1835423345879195884">the AAG presentation</a> and for advocating to take feedback from Jeff Burdges.</p>

Development of @noble/curves/sr25519 package by Paul Miller and audit sponsorship (1/2)

<h1 id="overview"><strong>Overview</strong></h1>
<p>MPC{dot}Snap&nbsp;is an innovative security suite that leverages Multiparty Computation to enhance account security beyond traditional hardware wallets. As exploits and attacks become increasingly sophisticated, keys with a single entry point are becoming more vulnerable. In the Polkadot ecosystem, hardware wallets don&rsquo;t fully support all pallet functions, leaving many community members who store their keys digitally at greater risk.<br /><br />Snaps was introduced to the public by Metamask in September 2023 and since then this architecture has been used for different use cases while providing users more functionalities with a similar experience and no learning curve. The biggest use case for Metamask Snaps so far is providing a compatibility layer for the non-EVM chains.<br /><br />We already have the &lsquo;Polkadot Wallet Snap by ChainSafe&rsquo; and &lsquo;Polkagate Snap&rsquo; in the ecosystem providing just the compatibility layer for Substrate chains on Metamask. MPC{dot}Snap goes a step further. Instead of merely offering wallet compatibility, MPC{dot}Snap introduces a comprehensive suite of Snap-Dapp-App, offering a robust alternative to traditional hardware wallets through the power of Multiparty Computation. Hardware wallets become vulnerable once their keys or seeds are exposed. In contrast, compromising the MPC.Snap would require an attacker to breach two separate devices or access keys and seeds stored through two distinct methods or channels.</p>
<p>&nbsp;</p>
<h1 id="impact"><strong>Impact</strong></h1>
<p>As MPC.Snap will support all the functionalities from existing pallets, overall it could turn out to be a better choice than hardware wallets, especially for community members who are looking to utilize the full potential of Polkadot ecosystem chains.</p>
<p>Outside of the EVM ecosystem, no other blockchain networks currently offer MPC-based Snap solutions. This presents a significant opportunity for the Polkadot ecosystem to introduce a leading, easily accessible, and highly secure wallet management solution. By doing so, Polkadot can not only enhance security for its users but also attract new users from other ecosystems, thanks to the minimal learning curve of the snap architecture inherited from Metamask.</p>
<p>In many regions, the cost of a phone is significantly lower than that of purchasing or importing a hardware wallet. This disparity creates a substantial barrier to accessible security for community members from various demographics and countries. MPC.Snap addresses this challenge by offering a more secure solution without any additional cost, as it can be utilized across two devices, with only one needing a camera. By lowering the entry barrier, MPC.Snap ensures that robust security is within reach for all users, regardless of their location or financial resources.</p>
<p>&nbsp;</p>
<h1 id="projectdetails"><strong>Project Details</strong></h1>
<h3 id="mpcsnap"><strong>MPC.Snap</strong></h3>
<p>MPC.Snap features an intuitive in-snap UI for conducting transfers and signing data, offering users a streamlined and efficient experience with or without companion dApp/UI. It securely holds the first key of the TSS {2,2} MPC pair, playing a critical role in our advanced security framework. Additionally, MPC.Snap is designed to be chain-agnostic, ensuring Polkadot ecosystem-wide support for all the substrate chains.</p>
<p>&nbsp;</p>
<h3 id="dapp"><strong>DApp</strong></h3>
<p>Our Dapp serves as the bridge between the MPC Snap and the mobile app, enabling a smooth pairing process. It&rsquo;s built with user-friendliness in mind, providing easy onboarding and a guided pairing experience to ensure that users can set up their secure wallets in just a few simple steps. The recovery mode will also provide a guided experience for account backup &amp; restore in case of device change. The DApp&rsquo;s &lsquo;Snap Store&rsquo; segment features all the snap-ready protocols from the Polkadot ecosystem, along with the support for convenient mini-apps.</p>
<p>&nbsp;</p>
<h3 id="mobileappssdk"><strong>Mobile Apps &amp; SDK</strong></h3>
<p>The mobile apps, available on both Android and iOS, are designed for convenience and accessibility. Users can utilize either the front or back camera to scan the pairing QR code, ensuring a flexible and straightforward setup. With a focus on UX/UI, the app can support multiple accounts and holds the second key(s) of each TSS {2,2} MPC pair, working in tandem with MPC.Snap to provide unmatched security without a dedicated hardware requirement. The mobile SDK opens up a way for existing wallets to inherit the security of MPC.Snap with minimal effort.</p>

<p>This component is a powerful JavaScript library for two-party SR25519 MPC signing using FROST protocol, based on the proposed @noble/curves/sr25519 package by Paul Miller. The sr25519-tss-js library is not only crucial for our project but is also designed for reuse in other TSS {2,2} applications, making it a versatile tool for developers across the Polkadot ecosystem. Until the @noble/curves/sr25519 package by Paul Miller gets audited, we will use the existing @noble/curves/ed25519 to create the ed25519-tss-js package. So initially the MPC.Snap will be based on ed25519, while the sr25519 support will be added down the line before the public release.</p>

<p>Snaps are not widely adopted by the Polkadot ecosystem projects, and most people are under the impression that snaps can be only used as wallets (but they can also be used for different use cases like mpc, accessibility, zk proofs, meta txs, analytics/visualization, automation actions, scheduling, etc.). We will have a weekly public working hour call (cohort) where projects from the whole Polkadot ecosystem can join and request to make their projects snap-compatible. If we don&rsquo;t have any pending requests in a specific week, we will raise PRs ourselves to add snap compatibility to the remaining projects from the ecosystem.</p>

Development of MPC{dot}Snap

The purpose of this proposal is to top up our total initial request from [REF #541](https://polkadot.polkassembly.io/referenda/541), as due to the fluctuation of DOT price, we received 13.95% less.

- Initial request: $34500, equivalent to 4471 DOT at $7.716 per DOT.

- Received (17.04.2024): $29687.44, equivalent to 4471 DOT at $6.64 per DOT.
 
- New request: $4812.56, equivalent to 724.78 DOT at $6.64 per DOT.

Given the successful deployment of the [Universal Hybrid Faucet](https://substratefaucet.xyz/) in production, we are now requesting the top up to fulfill our commitment of maintaining the faucet for 2 years, as proposed in the approved proposal. We refrained from rushing for the top up initially, prioritizing the completion of development.

View proposal [#541 here](https://polkadot.subsquare.io/referenda/541).

Thank you.


 Top Up request: Universal Hybrid Substrate Faucet

## Objective:
A one-stop testnet faucet for all the substrate chains that will also support EVMs on substrate chains making it the first **Hybrid Faucet** in the ecosystem. 
With XCM channels exploding already, we should presume the upcoming wave of next-gen Polkadot dApps is near! Most of them will leverage multiple parachains and solochains simultaneously. To cater to this future need we are introducing this universal faucet idea with single-click multi-chain disbursements to make cross-chain testing a breeze.

## Features:
#### Faucet with 2 modes: 
﹒ **Network switcher mode**: This can be utilized for individual disbursement on a specific substrate chain.

﹒ **Network selector mode**: This can be utilized for bulk disbursements on selected substrate chains. 
#### EVM support: 
All frontier-based EVMs will be supported right out of the box. While support for custom EVM implementations will be added on a rolling basis.
#### Attack Resilient: 
The Faucet will be immune to attacks using derived accounts. Also using web3/signer login, the faucet can be used only once a day across all the accounts from the signer.


## Cost and Timeline:
We are considering $500 per chain integration with 50% of the grant being vested for 1yr (vesting will be done in the same multisig with the contributors as signers). There are currently 69 testnets in the Polkadot ecosystem. Referencing the EMA30 which is **$7.51 per DOT** the total will be **4593 $DOT** which is ~34500$.
The complete development will be done within **4 weeks** with the additional service of maintaining the faucet for 24 months along with weekly integration for new testnets at no additional costs.


## Future scope: 
﹒ Support for Mainnets and further improvements based on the community’s feedback and suggestions.

﹒ We can also implement social login if required.

﹒ In-app integration with interfaces(like PolkadotApps) and wallets.


## About Us:
We are a collective of experienced contributors from EdgewareDAO looking to start the contribution journey in Polkadot with this small project.


#### Forum reference: (post by Gagan)
[https://forum.polkadot.network/t/universal-testnet-faucet-idea/6114](https://forum.polkadot.network/t/universal-testnet-faucet-idea/6114)


## Q&As:
#### Why do we need a universal testnet faucet?
The universal testnet faucet is quite crucial for developers who are looking to leverage technologies from different substrate chains in their stack. This will also complement the push towards multichain hybrid deployments.

#### How is it different from other faucets?
Currently, we don’t have a faucet that does single-click multi-chain disbursements in the whole substrate ecosystem. The ecosystem also doesn't have any ready-to-use faucet which supports all the testnets.
