Blitz Pro

Problem Statement

DescriptionBlitz unleashes the full power of 1inch Protocol to deliver 15 professional trading strategies that work 24/7, gaslessly, across 20+ blockchains—bringing every CEX feature to DeFi, and more.🚀 The Platform: Where 1inch Meets Professional TradingWe've built a comprehensive trading terminal that deeply integrates every 1inch API and protocol to create automated strategies. From basic stop-losses to complex grid trading and cross-chain TWAP orders via Fusion+, Blitz showcases what's possible when you fully leverage 1inch's infrastructure.📊 15 Trading Strategies Powered by 1inchStop-Loss/Take-Profit Ordersprotect your positions automatically using 1inch Limit Order Protocol v3's predicate functions. When market prices hit your thresholds, orders execute instantly without you being online. Our OCO (One-Cancels-Other) feature combines both for complete risk management—if your take-profit hits, the stop-loss cancels automatically.TWAP (Time-Weighted Average Price)breaks large orders into smaller chunks executed over time, reducing price impact by up to 85%. Perfect for whales or anyone trading size, TWAP uses 1inch's routing to find the best path for each chunk while staying under the radar.Grid Tradingcreates a ladder of buy and sell orders to profit from volatility.DCA (Dollar Cost Averaging)systematically accumulates tokens at regular intervals regardless of price.Trailing Stop-Lossfollows price upward, locking in profits while protecting downside.Iceberg Ordershide your true order size by only showing small amounts to the market.Bracket Orderscombine entry, stop-loss, and take-profit in one transaction.Conditional Orderschain multiple trades with if-then logic.VWAPexecutes based on volume patterns for optimal pricing.Momentum Tradingautomatically catches breakouts when price accelerates.Mean Reversiontrades when price deviates from moving averages.Range Ordersexecute only within your specified price bands.Scale In/Outenters or exits positions at multiple price levels.Arbitrage Protectioncaptures price differences across DEXs.Flash Crash Protectionautomatically buys extreme dips when markets panic.📈 Comprehensive Analytics DashboardOur dashboard transforms complex DeFi data into actionable insights. Track your active orders across all chains in real-time with visual progress bars and estimated execution times. Monitor your portfolio performance with P&L calculations, win rates, and risk metrics. The protection impact section shows exactly how much money you've saved from stopped losses and profits captured. Historical charts reveal your trading patterns and help optimize future strategies. Everything updates live using 1inch Price API and Portfolio endpoints.🎯 The 1inch AdvantageBlitz demonstrates the full power of 1inch's ecosystem in production. Every TWAP order generates 10-50 swaps through 1inch routers. Our Fusion+ implementation opens cross-chain trading to everyone. Most importantly, we're proving that DeFi can offer everything CEXs do—and more—while staying decentralized.🔮 The Future We're BuildingBlitz proves 1inch Protocol isn't just infrastructure—it's the foundation for DeFi's next generation. By combining Limit Orders, Aggregation, and Fusion+ into one seamless experience, we're showing how 1inch enables institutional-grade trading for everyone, true cross-chain composability, and professional tools that respect DeFi principles.This is DeFi's future. This is 1inch unleashed. This is Blitz.

Solution

How it's madeWe went all-in on 1inch Protocol, integrating10 different APIsand building the most comprehensive 1inch-powered trading platform to date. Every line of code showcases what's possible when you fully embrace the 1inch ecosystem.Core Tech StackFrontend: React + TypeScript + Vite gives us lightning-fast development with type safety. TailwindCSS provides the responsive, professional UI. We use ethers.js and WalletConnect for multi-wallet support across all major providers.Backend: Node.js monitoring service continuously watches for trigger conditions. When a stop-loss threshold is hit, our resolver executes the order using the pre-signed data. WebSocket connections ensure real-time price monitoring without overwhelming RPC endpoints.Smart Contract Integration: We interact directly with 1inch Limit Order Protocol contracts. Users sign orders containing predicate functions that define execution conditions. These predicates check price oracles, comparing current rates against user-defined thresholds.1inch APIs IntegrationSwap API: Core to every order execution. When stop-losses trigger or TWAP chunks execute, we route through 1inch's aggregation to access 300+ liquidity sources. We use both /quote for previews and /swap for actual execution, ensuring users always get the best price.Limit Order API (Orderbook): Powers our entire order system. We create, monitor, and manage limit orders with custom predicates for each strategy type. The API handles order creation, status checking, and cancellation.Spot Price API: Provides real-time price feeds for trigger monitoring. We poll continuously for active orders, using these prices to evaluate predicate conditions. Critical for accurate stop-loss and take-profit execution.Token API: Supplies all token metadata—symbols, decimals, logos. This allows us to support any token tradeable on 1inch without manual configuration.Balance API: Checks user funds before order creation and monitors balances for order viability. Prevents failed orders and improves UX by showing available trading power.Gas Price API: Optimizes execution timing. Our resolver uses this data to execute orders when gas is reasonable, saving users money on execution costs.Portfolio API: Powers our comprehensive analytics dashboard. Tracks positions, calculates P&L, and shows performance metrics across all chains and strategies.History API: Provides transaction history for our dashboard's historical performance section. Users can see all their past trades and strategy executions.Web3 RPC API: Provides reliable blockchain access across all supported networks. We use this for transaction monitoring and state verification.Transaction Gateway API: Ensures reliable transaction submission across chains. Handles resubmission and gas optimization automatically.1inch Protocol Deep DiveLimit Order Protocolforms our foundation. We create custom predicate functions for each strategy type—stop-losses use price comparison predicates, TWAP uses time-based predicates, and complex strategies combine multiple conditions. The gasless architecture means users sign once and never pay for monitoring or execution.Aggregation Protocoloptimizes every trade execution. When a stop-loss triggers, we don't just market sell—we route through 1inch to find the best path. For TWAP orders, each chunk gets independently routed for optimal execution.Fusion+ Integration(Architecture Ready): While Fusion+ is in development, we've built our system to support intent-based cross-chain orders. Our UI already supports chain selection for 20+ networks including Bitcoin, Solana, and Cosmos, ready for when Fusion+ launches.Notable Technical AchievementsHybrid Architecture: The most challenging aspect was balancing on-chain security with off-chain efficiency. Orders are created on-chain for immutability, but monitoring happens off-chain for gas efficiency. We built a monitoring system that ensures reliability—multiple backup nodes watch each order.TWAP Implementation: Creating true TWAP on limit orders required creativity. We generate multiple orders with increasing validity timestamps, ensuring they execute in sequence. Each order's predicate includes both time and price conditions. The result is professional-grade TWAP without custom contracts.Multi-Chain Order Management: We maintain order state across multiple chains using local indexing of blockchain events. Each chain is monitored independently, but orders are displayed in a unified dashboard.Why 1inch Was EssentialWithout 1inch's infrastructure, Blitz wouldn't be possible. The Limit Order Protocol provides the security and flexibility for complex strategies. The Aggregation Protocol ensures every execution is optimal. The comprehensive API suite gives us everything needed for professional trading features. Most importantly, the upcoming Fusion+ will enable true cross-chain trading without bridges or wrapped tokens.By leveraging every aspect of 1inch's technology stack, we've created more than just another trading interface—we've built a platform that showcases the full potential of DeFi infrastructure and points toward a future where decentralized trading is more powerful than centralized alternatives.
