Users peg bitcoin into a federation wallet and receive L-BTC on the sidechain, with transactions validated by a group of functionaries. Because Liquid functions as settlement infrastructure for exchanges, a compromise at this layer can have broad implications for funds across multiple platforms.",

      "market_impact_en": "Exchanges that rely on Liquid for settlement may face liquidity and withdrawal pressure if their bitcoin holdings were part of the affected federation wallet, making custodial and platform risk the primary transmission channel. Broader crypto sentiment around bitcoin sidechains and federated custody could also be affected, although the halted network and the attackers' white-hat claim leave the ultimate outcome uncertain.",
