About
The problem it solves # VCOP - Chainlink-Powered Peso-Pegged DeFi ## The Problem In the last ten years, the Colombian peso has lost about sixty-two percent of its value against the dollar. Selling your crypto to patch that hole? You erase your upside. Dollar-based DeFi loans? They liquidate you on the slightest dip. **There has to be a smarter way.** ## Our Solution **VCOP delivers that smarter way.** We help Latin American savers hedge against devaluation—without selling their crypto. Our system combines ultra-flexible collateral-backed loans with a peso-pegged stablecoin that stays 1:1 with the Colombian peso. **In one line: keep your crypto, spend in pesos, sleep at night.** ### **⚡ Chainlink Custom Logic Automation** **Smart Liquidation System** - Monitors all loan positions continuously using checkUpkeep/performUpkeep functions - Batch processes up to 50 positions per execution for gas efficiency - Risk-based prioritization with multi-tier response: Critical (95%+), Danger (85%+), Warning (75%+) - Automated vault-funded liquidations requiring no keeper capital ### **📊 Chainlink Price Feeds Integration** **Multi-Source Oracle System** - Primary: Chainlink Data Feeds (BTC/USD, ETH/USD on Base Sepolia) - Fallback: Manual price feeds with staleness protection - 6-decimal precision for consistent VCOP/USDC calculations ## How It Works ### **Step 1: You Set the Risk** Our Flexible Loan Manager lets you borrow up to 95% LTV—you control your risk level. ### **Step 2: Chainlink Guards You Every Block** - **Custom Logic Automation** monitors positions continuously - **Price Feeds** track risk metrics in real-time - **Smart Liquidations** use vault liquidity (no keeper capital needed) ### **Step 3: You Spend in Your Currency** VCOP maintains 1:1 peso peg through: - **Chainlink-powered** multi-source oracle system - Peg-Stability Module for instant VCOP↔USDC swaps https://github.com/rofergon/Vcop-Collateral-system-hook-main/tree/main/src/automation
How it's made
Challenges we ran into # 🛠️ Challenges I Ran Into ## **Designing Scalable Auto-Liquidation with Chainlink Automation** The main challenge: **How to create an autonomous liquidation system that scales from 10 to 10,000 loans without breaking the bank on gas costs?** ### **Key Design Challenges:** #### **1. Scalability vs. Cost** - **Problem**: Checking each position individually becomes prohibitively expensive - **Solution**: Batch processing - review 20 positions at once instead of one-by-one #### **2. Autonomous Decision Making** - **Problem**: Who liquidates positions 24/7 without human intervention? - **Solution**: Chainlink Automation with custom logic triggers #### **3. Capital Requirements** - **Problem**: Liquidators need upfront capital to repay debts - **Solution**: Vault-funded system provides capital automatically #### **4. Economic Sustainability** - **Problem**: Automation costs (LINK tokens) vs. protocol security - **Solution**: Intelligent batching reduces gas costs by ~80% ### **The Breakthrough:** **Batch Processing Philosophy:** ``` ❌ Traditional: Check position 1, then 2, then 3... ✅ Our Solution: Check positions 1-20 together Result: 1,000 positions = 50 batches instead of 1,000 individual checks ``` ### **Final Impact:** Transformed liquidation from a **manual, capital-intensive process** into a **fully automated, capital-efficient system** that maintains security at any scale. --- https://automation.chain.link/fuji/97089639364816243919913587083827994184217029587051624471430177225095950763757
