uArc: The AI & x402 Automation Layer for Arc ​uArc is a natural language DeFi automation platform and x402-native agent infrastructure built on Arc L1. It allows humans to manage DeFi via plain English and enables external AI agents to access execution infrastructure programmatically via the x402 API—paying per use in USDC without frontends, API keys, or subscriptions. ​The Problem & Solution ​DeFi automation currently suffers from high "configuration fatigue"—users must manually map contract addresses and parameters. For AI agents, the hurdle is worse: there is no standard, pay-per-use interface for on-chain tasks. Furthermore, micro-fees (like $0.002) are mathematically impossible on most chains due to gas overhead. ​uArc solves this by: ​Natural Language Parsing: AI interprets "Buy $200 ETH if it hits $2000" and constructs the on-chain automation struct. ​x402 Infrastructure: External agents use HTTP 402 (Payment Required) headers to pay for infrastructure on-demand using Circle Nanopayments. ​Arc-Native Economics: Every execution is profitable because Arc’s gas is USDC-denominated and sub-cent. ​How It Works ​Human Flow: User types a sentence \rightarrow AI parses intent, fetches live data (Curve, Aave) \rightarrow User signs once \rightarrow Automation is live. ​Agent Flow: External agent hits uArc API \rightarrow Attaches USDC Nanopayment signature \rightarrow uArc registers and executes the task autonomously. ​Key Technical Pillars: ​Vault Contract: Non-custodial storage where funds are only moved based on pre-approved rules. ​Modular Registries: Plug-and-play contracts for conditions (Price, Time, Balance) and actions (Swap, Lend, Transfer). ​Atomic Settlement: Fee transfers are bundled with execution; the agent only gets paid if the trade succeeds.

LineaAi is a sophisticated AI trading agent that combines cutting-edge blockchain technology with automated trading strategies. The system features a complete on-chain identity framework using ERC-8004 Agent Registry deployed on Sepolia, enabling verifiable agent authentication and reputation tracking. The agent autonomously discovers trading opportunities through dynamic token analysis, leveraging multiple data sources including CoinGecko trending data, Prism API technical signals, and CoinMarketCap market data. It executes trades on Kraken's futures platform with built-in risk management through smart contract validation. Key innovations include cryptographic explainability via EIP-712 signed checkpoints that create an immutable audit trail of every trading decision. Each trade is accompanied by human-readable reasoning and confidence scores, ensuring full transparency and accountability. The architecture includes a HackathonVault for capital management, RiskRouter for on-chain trade validation, and ReputationRegistry for agent performance tracking. The system supports both paper trading for testing and live trading with configurable risk parameters. The agent employs multiple trading strategies including momentum detection, dip recovery identification, and reversal pattern recognition. It automatically adapts to market conditions and can discover new trading opportunities across major cryptocurrency pairs. Built with TypeScript, Hardhat, and modern web3 technologies, Dumbai represents a new paradigm in autonomous trading where AI decisions are cryptographically verifiable and fully auditable on-chain.

## What are Qubic Perpetual Futures? **Qubic Perpetual Futures (PERP)** is a decentralized perpetual futures trading system built on Qubic, similar to GMX style perpetuals. It provides: - **PriceFeed Contract** - Oracle for real-time token prices (QUBIC, BTC, BNB, USDT) - **Perpetuals Contract** - Full trading engine with leveraged long/short positions - **Risk Management** - Automated liquidations, margin requirements, funding rates - **Fee Structure** - Opening, closing, and liquidation fees for protocol sustainability - **Account Management** - Multi-user support with per-user balance tracking PERP is designed to: - Create sustainable liquidity and trading volume on Qubic - Generate ongoing protocol revenue through trading fees - Provide transparent, non-custodial leveraged trading - Enable price discovery for Qubic ecosystem assets --- ## Perpetual Futures Solution PERP introduces a **comprehensive derivatives trading system** with modular architecture: 1. **PriceFeed Contract (Index 20)** - Manages real-time prices for 4 tokens 2. **Perpetuals Contract (Index 21)** - Core trading engine with full position lifecycle 3. **Risk Management System** - Automated margin enforcement and liquidations 4. **Funding Rate Mechanism** - Hourly rate-based incentive system to balance OI 5. **Fee Distribution** - Protocol fees, liquidation rewards, and fund accumulation In short: **PERP = Decentralized perpetuals engine + Price oracle + Risk management + Fee model.** --- ## How It Works (Step by Step) ### 1. Price Feed (PriceFeed Contract) #### Price Updates - **4 Supported Tokens**: QUBIC, BTC, BNB, USDT - **Price Precision**: 1e8 (8 decimal places) - **Oracle Updates**: Regular updates via authorized oracle node - **Timestamp Tracking**: Last update tick recorded for each token
