Jumper routes through third-party bridges, DEXs and DeFi protocols, so a failure or exploit at any of them can cost funds. Transactions cannot be cancelled once sent, bridges can be slow under congestion, and the output can change between quote and execution. Audits lower but do not remove smart contract risk. Jumper Perps cannot be used by residents or citizens of the United States or of sanctioned jurisdictions.

LI.FI Diamond facet exploit drained ~$10M. A newly added LI.FI Diamond facet allowed arbitrary calls, letting an attacker drain stablecoins from about 153 wallets with infinite approvals on Ethereum and Arbitrum. LI.FI blamed individual error during deployment and disabled the facet; Jumper, built on LI.FI, told its users to revoke approvals. LI.FI's report promised full compensation; BlockSec later states affected users were fully reimbursed (no LI.FI confirmation of payout found). https://li.fi/knowledge-hub/incident-report-16th-july

LI.FI swap-before-bridge contract exploited. An attacker abused an unchecked external call in LI.FI's swap-before-bridge function and drained about $600K from 29 wallets with open approvals. LI.FI disabled swap methods; this predates the Jumper app but is the same LI.FI contract stack. LI.FI's post-mortem and Revoke.cash say affected users were reimbursed (Blofin reported an offer to convert some losses into equity, with full refund as the default). https://blog.li.fi/20th-march-the-exploit-e9e1c5c03eb9
