DeFi Yield Analysis & Optimization

Overview

Analyze and compare yields across DeFi protocols, lending, liquidity provision, staking, and yield farming, to identify the best risk-adjusted opportunities and assess sustainability. DeFi yields are a real-time proxy for crypto market leverage demand, capital allocation, and protocol health.

Core Concepts

1. DeFi Yield Sources

Yield Source	Mechanism	Typical APY Range	Risk Level
Lending (supply)	Earn interest from borrowers	1-15% (stablecoins 3-8%)	Low-medium
Borrowing cost	Interest paid by borrowers	3-20%	N/A (cost side)
LP fees (AMM)	Trading fee share from DEX	5-50% (varies by pair)	Medium-high
Staking	Validator/delegation rewards	3-15%	Low-medium
Liquidity mining	Protocol token incentives	10-500% (unsustainable)	High
Restaking	Re-hypothecated staking yield	5-20% (ETH + AVS rewards)	Medium-high
Points farming	Off-chain points → future airdrop	Unknown (speculative)	Very high

2. Lending Rate Analysis

Lending rates as market signal:

# High borrow rates = high leverage demand = bullish sentiment
# Low borrow rates = low leverage demand = bearish / waiting

def lending_rate_signal(borrow_rate_stable, borrow_rate_eth):
    """Analyze DeFi lending rates for market sentiment."""
    if borrow_rate_stable > 15:
        stable_signal = "extreme_demand"    # Leveraged long via stablecoin borrowing
    elif borrow_rate_stable > 8:
        stable_signal = "elevated_demand"
    elif borrow_rate_stable > 3:
        stable_signal = "normal"
    else:
        stable_signal = "low_demand"        # Bear market, no one borrowing

    if borrow_rate_eth > 10:
        eth_signal = "extreme_demand"       # Shorting or leveraged strategies
    elif borrow_rate_eth > 5:
        eth_signal = "elevated"
    else:
        eth_signal = "low_demand"
