Sky Lending vs WBTC

Sky Lending is the flagship product of StableLab’s Sky ecosystem, enabling over‑collateralised borrowing of sUSDS and real‑world asset stablecoins. Interest accrues per‑second and can be paid in advance, allowing negative interest or fixed‑term loans. An on‑chain risk oracle adjusts LTV caps daily based on market volatility metrics sourced from Chainlink and Pyth.

Wrapped BTC (WBTC) is a Bitcoin‑backed ERC‑20 minted by BitGo under a multi‑sig controlled by merchants and custodians. Each token is 1:1 redeemable for BTC, with reserves published every 24 hours and verifiable on chain. WBTC accounts for more than 70 % of tokenised bitcoin on Ethereum and serves as core collateral for Aave, Maker and Compound.
