So, I guess you're saying the erc20 contract for USDT has a backdoor builtin? On the one hand, I feel like I would've heard about this before, but on the other hand, I don't follow crypto circles off HN and the crypto discourse here is... well, not very deep.
Not to sound skeptical, I'm going to go read more and really appreciate your comments.

- yieldcrv 3y agoyeah, USDC has the same function along with GeminiUSD by the Winklevoss twins and PaypalUSD all the “money in a bank account” stablecoins have a similar structure. It isnt based on any resolved regulatory appeasing, its just what they wanted to do and imagined would be helpful for regulatory compliance, but it also lets them just freeze anything and keep collecting interest on the associated dollars and never needing to have it available for redemption its a decent business model here is USDT’s contract code https://etherscan.io/address/0xdac17f958d2ee523a2206206994597c13d831ec7#code https://etherscan.io/address/0xdac17f958d2ee523a220620699459... in the outline you can look is the “addToBlacklist” method, alongside the “destroyBlacklistFunds” method not only can they freeze your address’ ability to transfer, they can unilaterally subtract your balance it is a centralized asset that simply settles faster on distributed ledger technology like blockchains there are a couple decentralized attempts at the same model using overcollateralization and no central issuer or central control or freezing function, DAI is the closest.
