The Big Tipper project is an extension of rfp.fund, which was funded for Kusama with KSM RFP #2. The project aims to unlock multi-sig RFPs for Polkadot, enable bounty curators to associate Child Bounties with RFPs, and deploy an "RFP Board" to consolidate ecosystem RFPs across Kusama/Polkadot Treasuries and Kusama/Polkadot Child Bounties created through the app. The project has a budget of $5,000 for development, $3,000 for UI, $1,000 for supervisors, and $500 for contingency. Supervisors include Leemo and Jay Chrawnna. Excess or unused funds will be returned to the treasury by the supervisors. The timeline includes submission on Big Tipper Track on June 8, development beginning on June 15, UI work starting on July 8, and public launch on AAG on July 16. The project has three milestones: Polkadot Multi-sig RFPs, Child Bounty RFPs, and UI & Mainnet Deployment. The project also discusses the differences between multi-sig RFPs and Bounty RFPs for Polkadot and supports a new Bounty Pallet with multi-asset and cross-chain capabilities.

Mimir is a multisig solution for Polkadot ecosystem users, including enterprises, DAOs, and large asset holders. They have a proposal to improve the platform with four key innovations:

1. Call Templates: These templates make it easier to do common tasks by reducing the need for manual data input.
2. Omni UX: This feature allows users to manage multi-sig accounts across different parachains, making it easier to use across the Polkadot network.
3. Mimir PAPI SDK: This software development kit helps more applications use multisig and proxy users, making it easier for developers to connect with Mimir.
4. Proposer & Multisig API: This allows businesses and DAOs to use multi-sig approval processes in their internal operations, like budgeting and decision-making.

Mimir already has over 2,000 users and is growing in the Polkadot ecosystem. They aim to become the standard for multisig operations in Polkadot.

RISC-V is gaining popularity in the decentralized internet, and Polkadot is already using it for its virtual machines. The first line of smart home devices built on RISC-V and integrated with Polkadot is being launched, with real hardware products and open-source firmware available on GitHub. A public kick-start campaign on IndieGoGo will test market interest in these web3-native, open-source, user-first solutions.

The campaign will launch three interconnected devices:
1. Altruist: an air quality sensor that publishes data to a decentralized map.
2. DevBoard Hikikomori: a developer-focused micro-controller dev board built on RISC-V, designed for engineers from both embedded and Web3 worlds.
3. RISC-V Smart Home Server: a server that unites open hardware, open connectivity, and open cloud, enabling control over smart devices without centralized cloud platforms.

The proposed budget includes funds for the Robonomics Creative Team, advertising and outreach, influencer engagement, and an independent code audit. The campaign aims to demonstrate a future rooted in transparency, decentralization, and open technology, and to lay the foundation for a long-term open ecosystem of devices, tools, and services.

SAGE, or Substrate Asset Game Engine, is a proposal by Rosťa aimed at benefiting the Polkadot ecosystem, particularly for junior developers and game developers. The main goal is to improve tooling for .net development in Polkadot, which is used by many projects like Xcavate, Ajuna, and PlutoFramework. Supporting SAGE will help these projects by allowing teams to focus more on their final products and less on low-level details.

Cedric, the main developer behind SAGE and his company Ajuna, have a proven track record of developing open-source tooling for the .net ecosystem and creating advanced on-chain games. Their work is well-maintained and has been beneficial for the community, as seen in the quick responses to GitHub issues and contributions from other developers.

SAGE has already shown its effectiveness in hackathons, with projects using Substrate.Net.Api winning major prizes. The .net tooling developed by Cedric and Ajuna is powerful and easy to use, which is crucial for the success of projects relying on it.

Marketing for SAGE is not necessary, as developers will naturally find and use the tooling if it is useful for their C# applications secured by Polkadot. SAGE aims to provide a full-featured solution for game developers who may not be familiar with blockchain technology.

The value brought by SAGE is proportional to the amount requested, with Cedric asking for a small percentage of the treasury funds. The impact on the ecosystem is already significant, and the potential for growth is even larger. SAGE offers more than just Unity SDK integration, including Substrate pallets and a JavaScript SDK.
