Spark vs WBTC

SparkLend is MakerDAO’s permissionless lending front‑end that pipes DAI liquidity directly from the Maker core vault into isolated lending markets. Because the backend uses D3M credit lines, borrowers enjoy below‑market rates that float with the DAI Savings Rate. Since launch on Ethereum mainnet in May 2023 Spark TVL has oscillated between 300‑600 million DAI and is governed by MKR Executive Votes.

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.
