Tether blacklisted four THORChain vault addresses on the Tron network on October 9, 2026, freezing about 1.45 million USDT and knocking the protocol’s Tron-based cross-chain swaps offline, according to Cointelegraph. Roughly three hours later the blacklist was gone.
THORChain technical co-founder Chad Barraford said the team had no warning from Tether before the freeze and no communication with the stablecoin issuer beforehand, Cointelegraph reported. Cryptobriefing reported the same point, citing Barraford, and noted the blacklist was lifted at 15:30 UTC that day.

Key facts
- Tether blacklisted four of the six vaults THORChain operated on Tron; those four held 93% of the protocol’s assets on that network (Cryptobriefing).
- About 1.45 million USDT was frozen across four wallets, per Cointelegraph, which reported Barraford said trading would resume roughly two hours after the addresses were unfrozen.
- Cryptobriefing put the freeze at about three hours, ending at 15:30 UTC, with balances restored and trading and deposits resumed.
- No hacks or thefts were reported on THORChain during the episode (Cryptobriefing).
- After the reversal, 19 other wallets remained blacklisted (Cryptobriefing).
Where the two reports differ
The outlets agree on the core sequence but split on timing. Cointelegraph, citing Barraford’s post, reported the addresses were unfrozen about two hours after the post and that trading would resume then. Cryptobriefing reported the freeze lasted roughly three hours, with the blacklist lifted at 15:30 UTC. Cointelegraph also reported that CoinPulseHQ reached out to Tether and THORChain for detail and received no immediate response.
Context for the action is not something either outlet established. Cryptobriefing noted THORChain had recently decided not to block addresses linked to a $387.5 million Bitget hack, and stated plainly that no established connection exists between that decision and Tether’s freeze.

Issuer risk lands on liquidity providers
USDT is issued by a single company that built a blacklist function into the token, letting it freeze balances at a given address. Cryptobriefing reported Tether has used that function more than 11,000 times, typically against wallets tied to scams, hacks or sanctioned actors. This instance targeted a decentralized protocol’s own operating infrastructure instead.
The concentration makes the exposure acute: with 93% of THORChain’s Tron assets sitting in the four affected vaults, one blacklist action took out nearly all of that side of the protocol. Liquidity providers who supply USDT to such a pool are carrying issuer risk alongside smart contract and market risk, Cryptobriefing noted. THORChain’s total liquidity across all assets is about $47.9 million, so the frozen amount was material without being existential.
The episode sits against a wider legal backdrop. Conduit Technology, a cross-border payments platform, sued Tether earlier that week alleging it froze $2.76 million worth of USDT in a wallet tied to a 2024 Brazilian investigation (Cointelegraph). Cryptobriefing also referenced that $2.76 million freeze as the subject of a lawsuit. Separately, two Thai nationals sued Tether in August over an alleged freeze of $42.4 million in USDT following what the report described as an informal request from US Homeland Security Investigations.
Why it matters
Tether’s blacklist is a switch one company controls, and this episode showed it can be thrown at DeFi infrastructure rather than only at suspected criminal addresses. That distinction matters to anyone treating a decentralized protocol as free of counterparty risk. It also matters to THORChain itself, which had to pause Tron swaps and liquidity-provider operations while the addresses were blocked. The reversal limited the damage, but the absence of any explanation leaves the same exposure in place.
What to watch
Three things will shape what follows: whether Tether offers any public explanation for the freeze and its reversal, what happens to the 19 wallets that stayed blacklisted, and whether THORChain changes how it holds stablecoin liquidity on Tron (both raised by Cryptobriefing). Any ruling in the suit over the $2.76 million freeze would test how much legal limit exists on the blacklist power.
