Tether, the issuer of USDT, restricted four THORChain vaults on TRON on October 9, making roughly $1.45 million inaccessible for about three hours. THORChain suspended TRON trading, deposits and transaction signing before the addresses were removed from Tether’s blacklist at about 15:30 UTC, with their balances intact. Co-founder Chad Barraford said the protocol received no advance explanation and sought clarification from Tether. Nineteen other addresses involved in the same freezing operation remained restricted. The reversal restored an existing stablecoin route but did not represent new capital inflows, fresh USDT issuance or evidence of stronger crypto demand. Lookonchain data cited in the report showed TRON USDT supply had risen by $18.67 billion to $94.25 billion, an increase of 24.7%. The $1.45 million affected represented about 0.0015% of that supply. The episode renewed questions about DeFi’s dependence on centrally controlled stablecoins and the limits of permissionless infrastructure when issuers can freeze tokens at the contract level.
