Aave vs BlackRock BUIDL

Aave V3 is the third iteration of the Aave liquidity market protocol, introducing Portals for cross‑chain liquidity, High‑Efficiency (E‑Mode) lending and Isolation Mode markets to compartmentalise risk. The refactor cuts gas costs by up to 25 % and adds real‑time supply/borrow caps that can be tuned by AAVE token governance. V3 is live on Ethereum, Optimism, Arbitrum, Avalanche, Polygon, Metis and Base, collectively holding several billion dollars in deposits secured by the Safety Module.

BUIDL is BlackRock’s tokenised U.S. Treasury fund issued on Ethereum in partnership with Securitize. Each share represents ownership in a money‑market fund holding short‑dated Treasuries and reverse repos, with NAV updated daily on chain. Qualified holders can redeem tokens for cash within T+1 settlement, and yield is streamed to wallets every business day.
