Ripple engineer Neil Hartner on September 8, 2026, publicly challenged the security of Flare's wrapped XRP (FXRP) bridge, which allows XRP to be used on Flare's smart-contract network. Flare co-founder Hugo Philion disputed the concern, pointing to the protocol's collateral, escrow, and verification mechanisms. Over 155 million FXRP have been minted on Flare, representing a substantial amount of XRP on a network separate from the XRP Ledger.
