Leigent — Autonomous DeFi Portfolio Agent on X Layer

Natural language-driven AI agent for intelligent DeFi portfolio management on X Layer. Built for the OKX Build X Hackathon — X Layer Arena.

🎯 What It Does

Leigent is an autonomous portfolio manager that speaks plain English:

You: "I want stable income"
Leigent: → Analyzes your current holdings
      → Recommends 50% USDC / 30% USDT / 20% OKB strategy (~3-8% APY)
      → Executes corrective swaps on X Layer DEX
      → Reports: "Swapped 0.5 ETH → 200 USDC. TxHash: 0xabc..."

You: "What's my portfolio worth?"
Leigent: → Fetches all wallet balances + DeFi positions
      → Shows: $1,234.56 total across USDC, OKB, USDT
      → Notes any staking rewards accruing

You: "Swap 10 USDC to OKB"
Leigent: → Gets best route via OnchainOS DEX aggregator (500+ sources)
      → Executes swap, reports tx hash + price impact
