Upbit briefly suspends Aptos transactions after people were able to deposit counterfeit tokens

Upbit, a major South Korean cryptocurrency exchange, suddenly suspended deposits and withdrawals of the Aptos $APT token after some users were able to deposit and withdraw fake versions of the token that were intended to spoof the original. Because of a bug in how Upbit verified tokens, transfers of the spoofed token were identified as transfers of the native Aptos token, which could have caused a massive loss if users began redeeming the fake Aptos tokens as though they were real.

However, a bug on the part of the counterfeiter prevented massive losses. The spoofer used only six decimal places instead of eight, meaning that those who tried to redeem the fake tokens only received $250 instead of $25,000.

Upbit later re-enabled Aptos transactions after patching the bug.

Much-anticipated "speedy" Aptos chain launches, processing 4 transactions per second and with 80% of tokens allocated to insiders

Aptos, a much-anticipated layer 1 blockchain backed by FTX and a16z, and created by a team of former Meta employees, launched to much anticipation on October 17. The team had bragged that the chain would be able to process 160,000 transactions per second, even more than Solana's claimed theoretical 65,000, and far more than Ethereum's ~15 or Bitcoin's ~7. Instead, after launch, Aptos was processing a painful 4 transactions per second.

This was not the only criticism of Aptos upon launch. The Aptos token was quickly put up for sale on exchanges including FTX and Binance, but Aptos had not yet published information about their tokenomics — leaving would-be investors trying to make decisions about whether to purchase a token about which they couldn't find even basic information. Once the tokenomics were published, people expressed concerns about the distribution: 80% were allocated to the team and investors and staked, enabling them to dump the staking rewards on retail investors.
