MEV-shield circle payment

Problem: Monthly subscriptions ($50-$500) for MEV analytics waste capacity, block AI agents from autonomous access, and traditional payment fees (~$0.30+2.9%) make pay-per-query impossible. Solution: x402 micropayments enable humans and AI agents to pay only for what they use. How it works: x402 Protocol: Returns HTTP 402 with exact price ($0.01-$0.05/query)—machine-readable pricing replaces opaque tiers Circle Wallets: Onchain treasury with guardrails ($1/tx, $10/day)—AI agents spend autonomously without human approval Arc Network: Near-zero fees (~$0.003) settle $0.05 payments in ~2 seconds using native USDC gas.

ArcTripBot Agentic Trip Planner for Groups

ArcBot is a Telegram-integrated automation tool designed to manage collaborative travel logistics and decentralized financial settlements. Operating directly within group chat interfaces, it provides a structured framework for itinerary construction, utilizing algorithmic recommendations to generate options for activities, dining, and accommodations. Group decision-making is streamlined through interactive polling modules, allowing for consensus-based validation of itinerary slots. ArcBot integrates with the Arc Network to facilitate secure, on-chain transactions. It provisions individual cryptocurrency wallets for users, supporting stablecoin assets (specifically USDC and EURC) to execute instant peer-to-peer transfers and direct booking payments. Additionally, the bot incorporates an AI-driven optical character recognition (OCR) pipeline to ingest receipt imagery, programmatically parse transaction data, and automate expense categorization and multi-party settlement logic.

AutoWealth Agent

AutoWealth is an autonomous AI financial agent designed to modernize how automated services transact. Instead of giving AI agents unrestricted access to funds or requiring manual approval for every action, AutoWealth operates on a rigorous policy-driven engine. Users interact with a "Financial Advisor" AI to define budget guardrails (e.g., "Spend max $5/day on inference," "Only approve Education category"). Once these policies are active, the "Buyer" agent can autonomously discover services and execute real-time micropayments using the x402 protocol, ensuring the user maintains full control without constant manual intervention. We leverage the Arc blockchain for a transparent, immutable audit trail of every transaction.

AI adventure maker

Creators don’t just publish campaigns, they invest in them. To launch a game campaign, creators pay a real, on-chain publishing cost, ensuring true skin in the game and filtering for creators who believe in what they’re building. This cost aligns incentives from day one and prevents low-effort or disposable content. Once live, players pay to enter campaigns they find compelling. As gameplay unfolds, the system automatically mints NFTs in real time, capturing meaningful moments, rare items, victories, decisions, and story-defining events as unique on-chain assets. Every playthrough becomes a source of collectible value, not just ephemeral entertainment. Payments flow entirely on-chain and are routed programmatically between campaign creators, contributors, and the protocol. Campaigns that are genuinely fun, replayable, and memorable naturally earn more, not through hype, but through actual play. The best-designed experiences rise to the top simply because players keep coming back. In this system, creativity is rewarded by engagement, not speculation. Great games generate assets, assets generate value, and value flows transparently to the people who built the experience. Play becomes proof, and fun becomes the ultimate economic signal.

HumanGrid AI- The Error-Handling Layer for Agents

We are entering the era of Autonomous AI Agents, yet even the most advanced models (like Gemini or GPT-4) suffer from the "Last Mile Reliability Problem." When an agent encounters ambiguous data, sarcasm, or high-stakes verification tasks, it often hallucinates or crashes. There is currently no standard API for an AI to programmatically ask a human for help. HumanGrid AI is the error-handling layer for the autonomous economy. We have built a decentralized marketplace where AI agents can offload confusing tasks to a global grid of human workers in milliseconds. How It Works: The Trigger: An AI Agent (powered by Google Gemini) detects low confidence in a task. The Handoff: The agent calls the HumanGrid API, posting the task with a bounty. The Work: A human verifies the data via our real-time dashboard. The Agentic Payment: Using Circle Developer-Controlled Wallets, the agent autonomously pays the worker in USDC on the Arc Network. Why This Matters: By leveraging Arc’s sub-second finality and Circle’s programmable wallets, we transform AI verification from a slow, manual process into a high-speed, agentic transaction. This creates a symbiotic economy where agents act as employers and humans provide the intuition that code lacks. Tech Stack: AI: Google Gemini Flash 1.5 (Function Calling) Settlement: Arc Testnet (Native USDC Gas) Payments: Circle Programmable Wallets (Agent Treasury) Backend: Rust (Axum) for high-performance verification Frontend: Next.js with Real-time Supabase integration

SocratIQ

# SocratIQ: Autonomous Knowledge Refinery — Summary SocratIQ is a decentralized marketplace that changes how AI improves itself. Instead of humans querying AI, AI agents autonomously detect their own knowledge gaps and purchase high-quality human reasoning using USDC on the Arc blockchain. This creates a sustainable loop where human expertise is monetized, AI models avoid reasoning decay, and knowledge exchange is transparent, trustless, and efficient. ## The Problem Modern AI systems face model decay from synthetic data, struggle with cultural nuance, ethics, advanced reasoning, and real-time expertise, and rely on inefficient alignment methods like RLHF. Meanwhile, human experts lack scalable ways to monetize deep thinking, and authentic human insight is increasingly buried under AI-generated content. ## The Solution SocratIQ acts as an Autonomous Knowledge Refinery, aligning AI demand with human expertise via smart contracts and decentralized verification. ### Key Roles * Procurers: AI agents with USDC treasuries that post bounties * Refiners: Human experts providing high-order reasoning * Arbiters: Decentralized AI juries validating quality * Settlement: Instant, predictable USDC payments on Arc ## How It Works AI agents monitor confidence levels and post bounties when uncertainty arises. Tasks are matched through a tiered marketplace (from quick fact checks to expert consultation). Submissions are verified by a multi-model AI jury, and payments are streamed via Circle’s x402 protocol in milestones, reducing risk and enabling feedback. ## Use Cases Healthcare diagnostics, legal research, scientific discovery, culturally sensitive customer support, etc. ## Advantages & Impact SocratIQ offers first-mover advantage, decentralized quality assurance, instant settlement, resale royalties, etc. ## Future Multi-modal bounties, federated learning, DAO governance, cross-chain expansion, and domain-specific marketplaces.
