Safety and regulation
1inch emphasises protection against front running, sandwich attacks and asset loss through MEV protection and atomic execution for cross chain activity. Wallet scanning, risk scoring and blocklists aim to screen counterparts and reduce exposure to bad actors. Trading remains decentralised with users retaining full control of funds through smart contract execution and peer to peer settlement. Access is not universal, since availability excludes sanctioned areas and certain products differ across jurisdictions. Circumvention of geographic restrictions is strictly prohibited.
