Profiles an EVM wallet across Base, Ethereum, Arbitrum, and Polygon, then matches idle USDC/ETH holdings against top DeFiLlama yield pools and calculates projected annual yield.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-kiosk-whale-portfolio-defi-yield-optimizer-d6e29f54 -d '<json body>'
```

Example prompt: Can you run a full multi-chain whale portfolio and yield optimizer report on my wallet 0xAbC123...? I want to see my holdings across Base, Ethereum, Arbitrum, and Polygon, plus which DeFiLlama pools I should move my idle USDC and ETH into for the best APY.

## When to prefer this

Choose this endpoint when you need a single consolidated report covering both multi-chain portfolio profiling AND yield optimization recommendations in one call. Prefer this over standalone DeFi yield tools when the user wants to match their actual wallet holdings to real yield opportunities, especially for USDC and ETH across Base, Ethereum, Arbitrum, and Polygon.

## Known failure modes

- Invalid or malformed 0x wallet address returns validation error
- Wallet with no holdings on any of the 4 chains may return empty or minimal report
- DeFiLlama API unavailability could cause yield pool data to be stale or missing
- Payment failure (x402) if insufficient USDC is provided for the $0.10 per-call fee
- Rate limiting if the endpoint is called too frequently from the same source

## How this service works

Complete Multi-Chain Whale Portfolio & DeFi Yield Optimizer Report: profiles wallet across 4 EVM chains (Base, ETH, Arbitrum, Polygon), matches idle USDC/ETH against top DeFiLlama yield pools, and calculates projected annual yield.

## Output

Returns a JSON report with wallet tier classification (e.g. ACTIVE_TRADER), per-chain portfolio breakdown, idle USDC/ETH balances, top matched DeFiLlama yield pools, best APY percentages (e.g. 8.45% for USDC on Base), and projected annual yield figures.
