tBTC Minting and Redemption Paused, Threshold Network Claims Sufficient Asset Reserves

tBTC minting and redemption have been temporarily paused, with Threshold Network stating that there are still sufficient assets to support it, and no funds have been lost. The cross-chain bridge wallet holds approximately 4,320 BTC, while the circulating tBTC is about 4,185. No unauthorized minting or Bitcoin transfer records have been found. In response to the Linux kernel vulnerability CVE-2026-98432, all tBTC node operators have completed server patches or temporarily shut down nodes while awaiting the release of a fixed version. The team has found no evidence that this vulnerability was used to attack tBTC nodes. One node operator reported a security incident unrelated to the vulnerability, resulting in approximately 0.5 ETH being transferred from its Ethereum account used for paying transaction fees for its tBTC node, which was offline at the time. The operator found no evidence that the signing key materials were accessed. Bitcoin transactions in the tBTC wallet require signatures from a majority of independent operators, and a single operator cannot transfer funds alone. The cross-chain bridge will reopen after security maintenance is completed, and the team will provide updates within 24 hours, with earlier updates if the situation changes.
