A Memecoin Launched From BNB Chain’s Tutorial Wallet. The Wallet’s History Turned It Into a Legal Case

A wallet created for a BNB Chain video tutorial has become the center of a very real legal fight.

The address was supposed to demonstrate how to launch a token. BNB Chain now says a former employee retained unauthorized access to its seed phrase, generated a new private key and used that access in connection with a memecoin called Asteroid Shiba, or ASTEROID.

This was not an anonymous outsider finding a software bug. It was an old operational key, a former insider and a wallet whose public history gave the new token instant credibility it had not earned.

The Block reports that the address was originally used in February 2025 to create TST, a test token shown in a BNB Chain tutorial. TST unexpectedly became a speculative memecoin after its name was visible in the video and Binance founder Changpeng “CZ” Zhao posted about it.

TST’s market capitalization eventually climbed above $50 million, even though Binance and BNB Chain repeatedly said they had not endorsed the token. The tutorial itself had unintentionally turned a demonstration address into a market signal.

BNB Chain removed the tutorial after the trading frenzy. Zhao said at the time that the private key for the creator address had been deleted.

Deleting that key still left the seed phrase as a recovery path.

A private key controls a wallet, but a seed phrase can recreate that key. Deleting one copy of the key is not enough if someone still possesses the recovery secret behind it.

BNB Chain says that is exactly what happened.

A wallet address was previously created by a former employee, which they then used to generate a token, as part of a video tutorial. That individual is no longer with the company as part of this incident.

The individual retained unauthorised access to the associated seed phrase…

In its statement, BNB Chain said the former employee created the address for the tutorial, retained unauthorized access after leaving the company and later used the same address independently in connection with the new memecoin.

The organization said it did not create, authorize, promote or participate in ASTEROID. It also said it is pursuing legal action and cooperating with relevant authorities.

BNB Chain did not identify the former employee, specify the jurisdiction or describe the legal claims it intends to bring. Those details matter, particularly because the public statement is an allegation rather than a court finding.

The onchain activity explains why the company responded so forcefully.

Analytics account Lookonchain said four newly created wallets bought 796.7 million ASTEROID tokens for approximately $10,000. That represented 79.67% of the token’s entire supply.

According to the same analysis, those wallets later sold 718.8 million tokens for 1,103 BNB, worth about $638,000 at the time. Lookonchain estimated the resulting profit at roughly $628,000.

A former @BNBCHAIN employee deployed the new token $ASTEROID, then used 4 newly created wallets to buy 796.7M $ASTEROID (79.67% of the total supply) for $10K.

The employee later sold 718.8M $ASTEROID for 1,103 $BNB ($638K), making a profit of $628K.

The Block said it could not independently verify Lookonchain’s assertion that the four purchasing wallets belonged to the former employee. The transactions and concentration are visible; the identity linking those addresses to one person is the part that requires additional evidence.

Even with that limitation, the launch pattern was exceptionally dangerous for ordinary traders.

A buyer seeing a token emerge from a known BNB Chain tutorial address could reasonably assume the wallet carried some official significance. That historical association was more valuable than any logo or social-media slogan because it was written into the blockchain itself.

But blockchains authenticate keys, not intentions.

The network could verify that the familiar address initiated the launch. It could not tell buyers whether BNB Chain approved the token, whether the person using the key still had authority or whether a former insider was exploiting an old credential.

That distinction is easy to miss in a memecoin market where traders treat deployer addresses, early wallets and famous ecosystem links as signals of legitimacy.

ASTEROID also appears to have imitated an existing project with the same name. The pre-existing Asteroid Shiba team said the newer token was a copycat launched through the Flap platform and had no affiliation with its project.

The result was a perfect storm: a recognizable creator address, a familiar token name, enormous early concentration and a market trained to move before it verifies.

The security failure reaches beyond one former employee.

Seed phrases created for tutorials should be treated like production secrets once their addresses become public and economically meaningful. Access should be inventoried, rotated where possible and retired through a documented process that assumes every recovery copy still exists until proven otherwise.

A tutorial wallet can become valuable years later for reasons nobody anticipated when it was created. TST already proved that a demonstration token could attract tens of millions of dollars in speculative value.

That should have made the underlying seed phrase a high-risk asset, even if the wallet held little money.

There is also a lesson here for anyone buying newly launched tokens: a trusted address is not the same thing as a trusted launch.

Check the project’s official channels and look at supply concentration. Examine whether the earliest buyers are fresh wallets funded from related sources.

Most importantly, do not confuse an address’s past owner with the person controlling its keys today.

BNB Chain’s legal action may eventually establish who controlled the wallet, whether the four trading addresses were connected and what laws were broken. For now, the episode has already exposed the central weakness.

The wallet’s history made ASTEROID look safer.

The wallet’s secret history made it dangerous.
