DeFi Lending Yield: Supplying Crypto for Interest
With DeFi lending protocols (Aave, Compound, MakerDAO, Spark, Morpho), you supply crypto to a pooled smart contract. Borrowers draw from that same pool against collateral, and whatever interest they pay works its way back to the suppliers. The supply rate isn’t set by anyone; it’s computed from how busy the pool is: supply_APR ≈ borrow_APR × utilisation × (1 − reserve_factor), with utilisation = total_borrowed / total_supplied.
In practice, stablecoin markets (USDC, DAI, USDT) tend to pay 2–8% APR depending on demand. Volatile assets like ETH or BTC sit lower, around 0.5–3% APR, since most borrowers would rather short stables. Aggregators like Yearn vaults sit on top of several lending markets at once, shifting funds toward the best rate and reinvesting the proceeds back into the supplied asset.
Applications
Parking idle stablecoins for a fairly predictable yield. Hedging long crypto positions. Giving leveraged traders the liquidity they need to exit. And building structured products on top, like looped lending or fixed-rate tranches via Pendle or Notional.
FAQ
Why is the rate variable? Utilisation gets recomputed on every block. The moment borrowers withdraw or fresh deposits land, the APR shifts with it. If you want something fixed, a few protocols (Notional, Pendle) build fixed-rate tranches on top of the variable market.
What are the main risks? Smart-contract bugs are the big one (rekt.news keeps the grim hall of fame: Cream $130M, Euler $200M). Beyond that, watch for oracle manipulation, the supplied stablecoin losing its peg, and governance attacks.
Is my deposit insured? No. Nothing like FDIC or FGC coverage applies here. Aave does run a Safety Module funded by AAVE stakers, but it’s capped and shouldn’t be mistaken for bank insurance.

Effective Field Capacity
Calculate the effective field capacity of a mechanized farming operation, FC = (v × L × Ef) ÷ 10, from the working speed v (km/h), the effective working width L (m) and the field efficiency Ef (decimal). The result, in hectares per hour, is the area the machine actually works per hour, already discounting time losses with turns, refills and overlaps (efficiency). The factor 10 adjusts the units. It is central to mechanization planning: it sets how many machines and hours are needed to complete an operation (planting, spraying, harvesting) in the available window. Enter the speed, the width and the field efficiency.
Marker Efficiency (Cutting)
Compute the efficiency of a pattern marker in cutting, E = (pieces area / marker area) · 100%, the fraction of the lay actually used by the patterns. The rest is the 'waste' between pieces, an unrecoverable fabric loss — the largest variable cost in garment making. Each percentage point of utilization saves a lot of fabric in scale production. Enter the pieces area and the total marker area.
