BNB Chain’s lawsuit over tutorial-wallet memecoin exposes staff access control gaps
BNB Chain says a former employee reused a seed phrase from a tutorial wallet to launch ASTEROID, netting an alleged $628,000 profit.
BNB Chain has confirmed it is pursuing legal action against a former employee accused of retaining unauthorised access to a company seed phrase and using it to launch a memecoin that allegedly generated some $628,000 in profit. The network’s statement, published on 1 August, marks the latest instance of internal wallet controls at a major blockchain project coming under scrutiny after staff departures.
According to BNB Chain, a wallet address had originally been created for a company video tutorial demonstrating how to generate a token. The organisation said the employee, who has since left the company, later derived a new private key from the retained seed phrase and used the address to launch a separate token without authorisation, promotion or involvement from BNB Chain itself.
Nearly 80% of supply acquired for $10,000
On-chain analytics account Lookonchain linked the wallet to a token called Asteroid Shiba, or ASTEROID, and reported that four newly created wallets spent roughly $10,000 to acquire 796.7 million tokens, equivalent to 79.67% of the token’s stated one-billion supply. Those wallets subsequently sold 718.8 million ASTEROID tokens for 1,103 BNB, valued at approximately $638,000, producing an estimated profit of $628,000, Lookonchain said, publishing the four addresses on BscScan for public review.
Blockchain records identify wallet activity rather than the legal identity behind it, so the attribution to the former employee rests on BNB Chain’s own statement and Lookonchain’s analysis rather than any confirmed court finding. BNB Chain said it is cooperating with authorities, but its announcement did not name the individual, disclose a jurisdiction, identify a regulator or court, or specify whether it is seeking damages, asset recovery or criminal charges.
CZ calls former employee “basically a scammer”
Binance founder Changpeng “CZ” Zhao reposted BNB Chain’s statement, describing the former employee as “basically a scammer” and urging users to “Stay SAFU.” His characterisation is an allegation rather than a legal determination, and no complaint, case number or court filing has yet been made public.
The episode highlights a structural vulnerability common to deterministic wallets: removing a private key from a device does not invalidate a retained copy of the underlying seed phrase, which can still be used to regenerate keys after an employee’s departure. BNB Chain has not disclosed when the individual left the organisation, how long the seed phrase remained accessible, when the unauthorised use was discovered, or whether other tutorial-related wallets are being reviewed.
Governance implications for exchange-linked chains
For an ecosystem that markets itself on institutional-grade infrastructure, the case underscores how informal internal practices, such as reusing demonstration wallets for public tutorials, can create lasting exposure long after the original purpose has passed. The absence of disclosed case details also leaves open questions about which jurisdiction’s courts or regulators, if any, will ultimately handle the matter, and whether affected token buyers have any recourse.
