1254 addresses holding approximately 878 million USDT in the ETH network have been added to the blacklist (frozen), thanks to the carefully provided function in the USDT smart contract: addBlackList
By the way, the parameter for the address in the blacklist function is called _evilUser.
The smart contract owner can also cleanse the evil using removeBlackList (0xe4997dc5) or completely destroy the evil funds with destroyBlackFunds (0xf3bdc228).
Such decentralization and non-custodianship.
In the DAI contract the blacklist function is absent, and the contract is immutable.
However, noble bankers can attack DAI and detach it from the dollar if desired, as happened in March 2023 when DAI dropped to $0.88.
It’s also worth noting that more than half of DAI reserves are backed by another stablecoin, USDC, which also lost its peg to the US dollar in March and dropped to $0.8713 because bankers decided to bankrupt Silicon Valley Bank, where the company held $3.3 billion of USDC reserves.
Stablecoins are useful for trading or quick transfers of not very large sums, but storing and preserving funds in these USD surrogates is highly not recommended. Your wallet may be blocked if you have USDT or USDC, or your assets may decrease in value in the case of DAI, but at least they will remain with you.
