Koo.xyz adopts an industry-leading **"Multi-Chain Capital Ingress + Single-Chain Unified Matching"** architecture. This guide outlines the technical vision and workflow of this expansion roadmap. *** ### 1. Core Architectural Design Principles Koo.xyz's multi-chain roadmap strictly adheres to three core principles: * **Frictionless On/Off-Ramp:** Deposit and withdraw directly from your preferred blockchain networks without the hassle of manually searching for cross-chain bridges. * **Maximized Capital Efficiency (Multi-Chain Yield Deployment):** Margin is not restricted to a single chain. Idle capital can be dynamically deployed across top DeFi lending pools on various chains, avoiding yield degradation caused by saturated liquidity on a single network. * **Unified Peak Performance on Arbitrum:** Regardless of where funds originate, account ledger tracking, order matching, position management, and risk liquidation are strictly consolidated and executed on Arbitrum L2. System laryers overview： * **Multi-Chain Asset Layer** (Ethereum, Base, etc.): Handles USDC deposits/withdrawals and routes idle margin to cross-chain yield pools (Aave/Compound/Morpho etc.). * **State & Permission Mapping**: A real-time bridge syncing multi-chain balances and account permissions to the core ledger. * **Core Calculation & Settlement Layer** (Arbitrum L2 && Engine): Manages NFT account states, executes millisecond order matching, and handles on-chain margin, liquidation, and final settlements. > Key Takeaway: Capital moves and earns yield freely across multiple chains, while trading matching and risk management execute strictly on Arbitrum. *** ### 2. Multi-Chain Deposits & "Yield-Bearing Margin" Optimization Once multi-chain support is live, your deposit experience and capital yield will receive a comprehensive upgrade: * **No Prior Bridging Required:** Deposit USDC directly on any supported network (e.g., Ethereum Mainnet, Base, etc.). * **Automatic NFT Account Mapping:** Upon a successful cross-chain deposit, the funds are automatically credited to your **Koo.xyz Account NFT** bound on Arbitrum, making them immediately available for trading. * **Diversified High-Yield Earn Mechanism:** The Earn module will route idle margin across top DeFi protocols on various chains based on risk-adjusted yield algorithms. This effectively solves the bottleneck of single-chain liquidity saturation, securing a stable "trade while earning yield" experience. *** ### 3. Multi-Chain Withdrawal Workflow To provide maximum capital flexibility for traders, withdrawals adopt an **"Arbitrum Verification & Multi-Chain Destination"** model: #### Withdrawal Workflow 1. You initiate a USDC withdrawal request on the Koo.xyz trading interface (connected to Arbitrum). 2. The on-chain system validates account health (ensuring equity remains within the safe margin buffer). 3. Upon successful validation, the withdrawal instruction is dispatched to your designated **target chain**, where the local vault contract transfers USDC directly to your wallet address. > **⚠️ Target Liquidity Notice:** Withdrawal execution depends on the available USDC liquidity in the official vault on the target chain. If your selected network temporarily lacks sufficient vault balance, the request will be rejected. Simply select another chain with ample liquidity to complete your withdrawal smoothly—your funds are always safe. *** ### 4. Phased Rollout Roadmap Multi-Chain support will be rolled out progressively following rigorous security audits and liquidity testing: | Phase | Target Networks | Core Features | Strategic Focus | | ---------------------- | ------------------------------------------ | --------------------------------------------------------------- | --------------------------------------------------- | | **Phase 1 (Current)** | **Arbitrum L2** | Core Trading, Base Deposits/Withdrawals, NFT Account Control | Ensure ultra-low latency & secure liquidations | | **Phase 2 (Upcoming)** | **Ethereum Mainnet** | Fast Mainnet USDC On/Off-ramp, Mainnet Aave Yield Routing | Onboard institutional capital & whale traders | | **Phase 3 (Mid-term)** | **Base** | Low-cost Multi-Chain Deposits, Expanded Ecosystem Composability | Expand retail ecosystem & low-cost deposit channels | | **Phase 4 (Future)** | **More High-Performance L2s / EVM Chains** | Automated Global Liquidity Rebalancing | Expand based on capital efficiency & user demand | *** ### FAQ **Q1: Will depositing on different chains create separate trading positions?** **No.** Regardless of which chain you deposit from, all funds are denominated in USDC and mapped directly to your single **Koo.xyz Account NFT**. You trade with a unified cross-margin account; your positions and PnL will never be fragmented across chains. **Q2: Will depositing on Ethereum Mainnet slow down my trading execution?** **Not at all.** Deposit pathways are completely decoupled from order matching pipelines. Multi-chain capabilities only affect the capital ingress/egress channels. All order placement, cancellation, matching, and risk engine calculations remain strictly on Arbitrum L2 and system engine, preserving millisecond-level responsiveness. **Q3: Can I also claim $KFC staking dividends across multiple chains?** **Yes.** Platform fee dividends earned by staking $KFC will also follow the "Arbitrum verification, multi-chain destination" model, allowing you to freely claim your USDC dividends on your preferred network. *** > **📌 Note:** Supported networks, launch schedules, and chain-specific withdrawal limits are subject to official announcements and interface updates. --- # Agent Instructions This documentation is published with GitBook.
