Why This Vault?

The Moonwell Flagship USDC vault is one of the safest places to earn yield on Base:

Powers Coinbase — Provides $20M+ liquidity to Coinbase's BTC/ETH borrow products
Blue-chip collateral only — Loans backed by ETH, cbETH, wstETH, cbBTC
Conservative LTV ratios — Healthy collateral requirements
Isolated markets — Risk is compartmentalized
Battle-tested — Morpho's codebase is <650 lines, immutable, extensively audited
Multi-layer governance — Moonwell DAO + Block Analitica/B.Protocol curators

Current APY (~4-6%)

Component	APY	Source
Base yield	~4-5%	Borrower interest
Rewards	~0.5-1%	WELL + MORPHO via Merkl
Total	~4.5-6%	Sustainable, from real demand

Yields come from real borrowing demand, not unsustainable emissions.

Security

⚠️ This skill manages real funds. Review carefully:

Private keys loaded at runtime from environment variable
Keys never logged or written to disk by scripts
All transactions simulated before execution
Contract addresses verified on each run
Scripts show transaction preview before sending

Recommended Setup

Dedicated wallet — Create a hot wallet just for this skill
Limited funds — Only deposit what you're comfortable having in a hot wallet
Keep gas funded — Maintain small ETH balance on Base for transactions

Error Handling

Error	Cause	Fix
Insufficient USDC	Not enough USDC in wallet	Bridge/transfer more USDC to Base
Insufficient gas	Not enough ETH for tx	Add ETH to wallet on Base
Wallet not configured	Missing config	Run `npx tsx setup.ts`
PRIVATE_KEY not set	Missing env var	Set `$env:PRIVATE_KEY="your-key"`

Dependencies

Scripts require Node.js 18+. Install deps before first run:

cd scripts && pnpm install
