Upbit Accidentally Accepts Counterfeit APT Tokens, Initiates Retrieval Efforts
Upbit, South Korea’s largest cryptocurrency exchange, is reported to have accepted deposits of counterfeit Aptos (APT) tokens, mistaking them for their legitimate counterparts. The exchange has been reaching out to the sellers of these tokens by phone, requesting their recovery. This news has been circulating in several online crypto communities since the afternoon of September 24 (Korea Standard Time).
Upbit’s responses
On September 24 at 15:47 KST, Upbit announced a temporary suspension of deposit and withdrawal services for APT due to maintenance on the APT wallet. Following this, at 22:32 KST on the same day, Upbit explained that system maintenance was undertaken after identifying an unusual attempt linked to APT deposits. The crypto exchange went on to announce that the deposit and withdrawal services for APT would resume at 23:00 KST on the same day.
DeFi degenerates’ insights
In relation to this incident, Definalist, a group of DeFi degenerates based in Korea, shared insights on X (formerly Twitter). The group stated: “It seems that during the process of reflecting $APT coin deposits, there was a failure to check the type arguments, and all same functions transfers were recognized as the same APT native token. … If all APT ecosystem tokens were sent to Upbit’s wallet, they would have been mistakenly treated as APT native coins.”
Decimal place difference
Definalist also remarked on the fortunate nature of the counterfeit APT token having six decimal places, in contrast to the authentic APT token’s eight. They noted that if the deceptive token had mirrored the genuine token’s decimal places, the market disruption could have amplified a hundredfold. Meanwhile, the value of the counterfeit APT tokens deposited into Upbit is estimated to be about KRW 20 million (approximately $15,000).
