Circle and Tether have frozen stablecoins in a wallet linked to Thursday's $351.6 million Bitget hack, though the amount is a small fraction of the total. Circle blacklisted the address, which Etherscan labels "Bitget Exploiter 8," at 05:00 UTC Friday, onchain data shows. The wallet holds about 170.47 ETH, 218,023 USDT and 99,990 USDC. Blockchain security firm MistTrack said Tether has since banned the wallet too.
