OceanFin is a non-custodial platform that maximizes your Polkadot DeFi earnings with automated, data-driven strategies—no middlemen, just high-yield opportunities.

• Non-custodial: Users retain 100% control of assets
• DeFi Builder: Visual drag-and-drop interface for composing complex strategies
• AI-Powered Strategy Generation: Create strategies from natural language prompts
• One-Click Execution: Eliminate manual protocol hopping and spreadsheet math
• Real-time Simulation: Preview strategy outcomes before execution
• Transparent & Secure: Full visibility into strategies and execution
• Cross-chain Ready: Built for Polkadot ecosystem

• Make DeFi simple and accessible—no expert knowledge required
• Keep assets fully under user control
• Automate strategy discovery and execution
• Provide clear, real-time activity tracking
• Enable seamless cross-chain operations

Build complex DeFi strategies with a drag-and-drop interface. No coding required.

Key Features:

• Visual workflow canvas powered by ReactFlow
• Drag-and-drop operation nodes (SWAP, SUPPLY, BORROW, JOIN_STRATEGY)
• Smart connection validation with business rules
• Real-time price estimation and APY calculations
• Interactive configuration panels
• One-click strategy deployment

Supported Operations:

• SWAP - Exchange tokens via Hydration DEX
• SUPPLY - Deposit tokens to lending pools
• BORROW - Borrow tokens against collateral
• JOIN_STRATEGY - Convert to liquid staking derivatives (GDOT/VDOT)
• ENABLE_E_MODE - Enable efficiency mode for higher LTV

Access: Navigate to /builder in the app

Generate executable DeFi strategies from natural language using Google Gemini AI.

How it works:

1. Describe your strategy in plain English
2. AI generates a complete strategy with validation
3. Review the visual preview and risk analysis
4. Execute with one click

Example Prompts:

• "Create a gdot looping 3 loops"
• "Supply DOT and borrow USDC"
• "Maximize yield with moderate risk"

Features:

• Natural language processing with Gemini AI
• Automatic strategy validation
• Real-time simulation with accurate amounts
• AI-powered risk analysis
• Interactive strategy preview

Access: Navigate to /prompt in the app
