description	Find best DeFi yields across protocols and deposit into vaults

Yield Aggregation

Use the yield tool to find the best DeFi yields and deposit into vaults.

When to Use

• User asks "where can I earn yield on USDC?" or "what's the best APY?"
• User wants to deposit into a yield vault
• User wants to check their vault positions
• User asks about DeFi yield opportunities across protocols

Data Source

All yield data comes from DeFiLlama's yields API (yields.llama.fi/pools), which aggregates data from 400+ protocols across all EVM chains. Data refreshes every 5 minutes.

Actions

Action	Description	Required Params
search	Search yield pools with filters	(all optional)
top_yields	Best yields for a specific asset	asset
deposit	Deposit into Yearn V3 vault on Base	vault/asset, amount
withdraw	Withdraw from vault	vault/asset, amount
positions	View vault positions	(none)
vaults	List available vaults	(none)

Available Vaults (Base)

Vault	Asset	Standard
yvUSDC	USDC	ERC-4626
yvWETH	WETH	ERC-4626
yvDAI	DAI	ERC-4626

Common Flows

Find best yields for an asset

yield action=search asset=USDC chain=base
yield action=top_yields asset=USDC chain=base

Search with filters

yield action=search chain=base stable_only=true min_apy=5 min_tvl=1000000
yield action=search project=aave chain=ethereum

Deposit into a vault

yield action=deposit vault=yvUSDC amount=1000
yield action=deposit asset=WETH amount=0.5

Withdraw from a vault

yield action=withdraw vault=yvUSDC amount=max
yield action=withdraw asset=WETH amount=0.5

Check positions

yield action=positions

Search Parameters

• chain — Filter by chain (base, ethereum, arbitrum, optimism, polygon)
• asset — Filter by asset symbol in pool name
• project — Filter by protocol (aave, yearn, moonwell, morpho, etc.)
• min_tvl — Minimum TVL in USD (default: $100K)
• min_apy — Minimum APY percentage
• stable_only — Only stablecoin pools
• limit — Max results (default: 20)

Important Notes

1. Search covers all protocols — DeFiLlama data includes Aave, Yearn, Moonwell, Morpho, Pendle, and 400+ more
2. Deposits are Yearn V3 only — Direct deposit execution currently supports Yearn V3 vaults on Base (ERC-4626). For Aave deposits, use defi_lend tool instead.
3. No new dependencies — Uses DeFiLlama public API and direct contract calls
4. APY is variable — Displayed APYs are current rates and fluctuate over time
5. Wallet required — deposit, withdraw, and positions require a connected wallet
6. TVL filter — Default $100K TVL minimum to exclude dust/dead pools
