LinkedOut

LinkedOut is an AI-powered crosschain automation platform that simplifies Web3 workflows such as swaps, bridging, contract calls, and DeFi deposits. It combines Avail Nexus intents, LayerZero bridging, Hedera A2A, and natural-language AI agents to let users perform complex, multi-chain operations with just one signature and one command. Instead of manually switching networks, signing multiple times, and tracking transactions across explorers, users can simply instruct LinkedOut through familiar Web2 interfaces like Telegram or Gmail — for example, typing “Swap 50 USDC on Base for HBAR on Hedera.” The system automatically parses the command using an LLM, builds a deterministic workflow, and executes it via the LayerZero. LinkedOut runs client-side, ensuring decentralization and user control while integrating Pyth oracles for condition-based actions (e.g., bridge only when ETH > $3,800). The alpha version already demonstrates live Telegram-triggered workflows and crosschain intent execution across Avail, Base, and Hedera testnets. In essence, LinkedOut unifies AI, interoperability, and automation — making Web3 tasks as seamless as chatting with an AI bot.

LinkedOut is built using a combination of Avail Nexus SDK for intent creation, LayerZero adapters for cross-chain messaging, and Hedera SDK for A2A transfers. The frontend is developed in React and TypeScript, with WalletConnect and MetaMask used for wallet interactions and EIP-712 signing. Natural-language inputs are parsed by an LLM pipeline that converts user text into structured JSON workflows, validated against safe templates before being transformed into signed intents. Each signed intent contains all the transaction steps, oracle checks, and revert policies, allowing execution through lightweight relayers without a central backend. The relayers perform crosschain actions by interacting with on-chain proxy contracts that handle swaps, bridging, and deposits, while maintaining auditability and user safety. Telegram and Gmail serve as communication layers for triggers and notifications, allowing users to issue commands or receive transaction updates directly in chat. The system leverages Pyth price feeds for real-time conditions, Dockerized Node.js microservices for execution, and compact serialization for multi-step intents to enable a single-signature UX. The project’s architecture is fully modular — designed to extend to more chains like Polygon and Arbitrum — and demonstrates a novel, AI-first, client-side approach to Web3 automation powered by Avail Nexus intents.
