Aave vs USDT0

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.

USDT0 is the wrapped form of Tether issued by the cross‑chain router LayerZero to enable omnichain fungibility between Ethereum, Arbitrum, Optimism and BSC. The 0‑suffix indicates that redemptions are only possible through the canonical bridge rather than via Tether Treasury. The token carries a 0.1 % mint fee that is burned to offset bridge security costs.
