BNB Chain said a former employee used lingering access to the seed phrase of a company-linked tutorial wallet to launch the unapproved meme coin ASTEROID on Aug. 1, 2026, after earlier using the same address in 2025 for the TST video-tutorial token. The network said ASTEROID briefly reached a market capitalization of $10 million within its first four hours and drew thousands of holders, but stressed that it "did not participate in the creation of this token" and has "no control over the token or wallet address." BNB Chain said it is pursuing legal action and cooperating with relevant public authorities. On-chain analytics firm Lookonchain separately said four wallets linked to the ex-employee bought about 80% of ASTEROID's supply for around $10,000 and later sold for about $638,000, though those wallet links and the profit estimate have not been independently verified.
