# Hedgera — Social Token Indexes on Hedera ## Overview Hedgera is a Hedera-native platform for creating, buying, and redeeming on-chain token indexes. Each index is an ERC-20–compatible token backed 1:1 by a basket of Hedera-based tokens held in a smart contract vault. Users can mint index tokens with USDC-H, redeem them for the underlying assets, and track performance on-chain. Hedgera also includes a social layer where approved curators can launch their own indexes and earn a share of mint/redeem fees. --- ## Problem - Diversifying into multiple Hedera tokens requires multiple transactions and manual portfolio management. - There is no simple, trustless way for curators or influencers to monetize and share curated token baskets. - Current index products are mostly Ethereum-based and not available natively on Hedera. --- ## Solution Hedgera streamlines index investing on Hedera: - **Mint** — Deposit USDC-H, the protocol swaps into index constituents and mints index tokens. - **Redeem** — Burn index tokens to receive the underlying assets back. - **Curator Indexes** — Curators define constituents and earn a share of the fees from mint/redeem activity. - **On-Chain Transparency** — All vault holdings and fee flows are verifiable on Hedera. --- ## Implemented MVP Features - Multiple indexes, each with: - Fixed constituents and weights. - Configurable mint/redeem fees. - Assigned curator address for fee distribution. - Mint and redeem functionality using Hedera EVM contracts. - Fee splitting between platform and curator. - Next.js frontend with MetaMask integration. - Leaderboard by index mint volume. --- ## Technical Architecture - **IndexRegistry** — Stores metadata for all indexes and their configuration. - **IndexFactory** — Deploys a BasketVault and IndexToken for each new index. - **BasketVault** — Holds constituents, executes swaps on mint/redeem, controls IndexToken supply, enforces slippage caps. - **IndexToken** — ERC-20 compatible token representing index shares, minted/burned by its BasketVault. - **FeeSplitter** — Receives and distributes mint/redeem fees between the platform and the curator. - **Router** — Handles token swaps via integrated Hedera DEX - SaucerSwap --- ## Tokenomics - **Mint Fee:** 0.20% - **Redeem Fee:** 0.20% - **Fee Split:** 60% to platform, 40% to curator. --- ## Tech Stack - **Smart Contracts:** Solidity on Hedera EVM. - **DEX Integration:** SaucerSwap . - **Frontend:** Next.js, wagmi, MetaMask. ---

As you interact with the wallet, the AI provides recommendations to improve your strategies, ensuring that your financial operations remain effective in an ever-changing market. - **Complete Control and Security** With Mariposa Plus, your assets are secured with the latest cryptographic methods, and your keys are never exposed to third parties. Enjoy peace of mind knowing you maintain full control over your digital assets while benefiting from a simplified user experience. **Impact & Vision** Mariposa Plus is designed to: - **Simplify Blockchain for Everyone**: By removing the complexities of traditional Web3 interactions, we are making blockchain accessible to anyone, regardless of their technical knowledge. - **Automate and Optimize Financial Decisions**: Save time and reduce manual effort by letting AI handle your financial strategies, providing automated, hands-off asset management. - **Enhance Financial Control**: Give users more control over their financial future, while still leveraging the power of AI to improve their strategies and decision-making. - **Drive Web3 Mass Adoption**: Reduce friction and increase adoption of blockchain technologies by making them more user-friendly and secure. Mariposa Plus allows anyone to execute complex blockchain transactions with ease—no coding required. Simply tell the wallet what to do, like "send $50 in HBAR to Alex" or "swap USDC for HBAR," and let the AI handle all the technicalities, from gas optimization to routing. Beyond basic transactions, Mariposa Plus introduces a powerful AI agent capable of automating personalized financial strategies. Want to buy HBAR whenever Bitcoin drops by 5%? Just chat with the AI and set your trigger—Mariposa Plus will take care of the rest. The wallet works with multiple blockchains, providing seamless, real-time automation for both new and experienced users. In a market where 80% of new crypto users abandon wallets due to complexity, Mariposa Plus stands out by making blockchain accessible, intuitive, and secure. Whether you're a casual user, passive investor, or active trader, Mariposa Plus is the smart, simple way to interact with the Web3 world.

 **Your Agentic identity and payment platform on Hedera.** Effisend is an AI-powered identity and payment platform that lets users pay with their face, using secure token rails. A built-in AI agent handles bill splitting, recurring payouts, and optimal routing. Face‑scan login removes seed phrases and friction, making accelerated, biometric-native payments intuitive. ## Problem Onboarding new crypto users has become increasingly challenging. This process should be as simple as joining the traditional banking system, but complex wallet creation and limited adoption of account abstraction have created significant barriers. In Q1 2024, we encountered a practical challenge while deploying telecommunication systems in an underserved community in Mexico.  The problem became clear: we needed to pay these community members regularly, but doing so was difficult. Managing payments for a few households might be manageable, but scaling to 300 monthly payments presented significant hurdles. This difficulty stems from Latin America's financial landscape where, according to the World Bank, nearly half the population remains unbanked or underbanked. This limits access to secure savings, payments, and formal identification. Such financial exclusion leaves people vulnerable to theft, inflation, and economic instability. Traditional banking has failed to reach these communities effectively. While cryptocurrency offers a potential solution, its adoption remains low due to complexity, trust issues, and limited local infrastructure. *The region is ideally positioned for stablecoin adoption, especially considering the volatility of national currencies.* ## System Architecture & Tech Stack [](https://github.com/altaga/EffiSend-Hedera?tab=readme-ov-file#%EF%B8%8F-system-architecture--tech-stack) EffiSend is built from the ground up to leverage a modern Web3 infrastructure, ensuring scalability, security, and a seamless user experience.  *(The system diagram illustrates how the EffiSend frontend and backend services interact with the Hedera network via its native services like HTS. The SAUCE and USDC tokens are shown as the primary assets for rewards and payments.)* ### Core Components: [](https://github.com/altaga/EffiSend-Hedera?tab=readme-ov-file#core-components) - **[Hedera](https://hedera.com/)** Serves as the core distributed ledger powering all EffiSend transactions. Hedera's hashgraph consensus provides unparalleled speed, low-cost transactions, and fast finality, making it the ideal foundation for a high-throughput application like EffiSend. - **[SAUCE](https://www.saucerswap.finance/)** The primary token for **rewards** within the EffiSend ecosystem. As the main utility token of SaucerSwap, the leading DEX on Hedera, SAUCE is deeply integrated into the community, driving user engagement. - **[Langchain (AI Agent)](https://lanchain.com/)** The framework behind our AI agent, **DeSmond**. It enables natural language processing, allowing users to execute transfers, check balances, and perform other actions through simple conversation. - **[DeepFace](https://viso.ai/computer-vision/deepface/)** Powers our **Face-ID** verification system. DeepFace provides real-time facial recognition with anti-spoofing features, ensuring that wallet access and transactions are both frictionless and highly secure.

@vingitonga · payment gateway
Novalax is a payment gateway and platform for onchain payments of USDC directly on Hedera EVM Network. Novalax has been powered by x402 protocol, which enables seamless, secure, and automated payments for data and digital services. ***Why Build Novalax*** In April, we had develop [Novix AI Agent Marketplace](https://github.com/VinGitonga/novix_marketplace) marketplace for Hedera x AI hackathon, we had a challenge with monetization and payments for creators and AI agents. Moreover we needed to bridge the gap for a Web3 economy especially for autonomous agents and modern users. For AI Agents: AI agents and APIs need a programmatic, HTTP-native way to pay for data and resources in real-time, without relying on traditional, centralized payment gateways. For Users: Users expect a frictionless experience, where payments for premium files or content can be made with a click, without navigating complex dApps. For Businesses: Businesses need a unified platform to manage all their on-chain revenue, whether it's from AI agents paying for API calls or users paying for subscriptions. Novalax solves these challenges by use an web3 and a HTTP request that makes payments easier and thus empowering a new era of decentralized commerce. ***What did we build on Novalax*** Novalax is built on x402 protocol and Hedera EVM Network *Core Tech: OnChain Payments* Novalax is built on the x402 protocol, a standard that activates the HTTP 402 "Payment Required" status code. This allows us to make payments an intrinsic part of the HTTP request, creating a native payment layer for the blockchain. - HTTP-Native Payments: Novalax enables real-time, on-chain payments for data and API calls directly over the HTTP protocol. - On-Demand Payments: This technical core is the foundation for all our payment models, from one-time transactions to recurring subscriptions. Stablecoin Native: All transactions are settled in USDC, providing a reliable and non-volatile payment experience. *For AI agents: Programatic Payments of Resources* AI agents can now act as independent economic actors. - Pay for Access to Data: Agents can use the x402 protocol to pay for access to data and resources programmatically, without human intervention - Programmatic API Monetization: This enables developers to create true pay-per-use APIs, where every single API call can be monetized with a secure, on-chain transaction. *For Users & Businesses: Can get paid in USDC.* - For Users: Users can interact with an AI agent in Telegram to request premium files. The AI agent generates a payment link, and the user signs the transaction on the web to receive instant access. - For Businesses: Businesses get a unified dashboard to generate payment links for both one-time and recurring payments. They can track all revenue from AI agents and users, and manage everything from one place.
