Summary

Astera.fi is a DeFi credit facility and lending protocol operating on Ethereum's Linea Layer-2 network, issuing the asUSD stablecoin through both over- and under-collateralized mechanisms. On October 9, 2025, the protocol suffered a flash loan exploit via a liquidity index inflation attack that drained approximately $821,856–$880,000 across three lending pools. The protocol has been flagged by ZachXBT and market data indicates near-zero trading activity for asUSD, with the token appearing to have effectively ceased normal operation post-exploit.
