On December 5, Farcaster founder Dan Romero announced in a post that Clanker’s first presale project—House—sold out in 30 seconds. A screenshot shows the presale’s hard cap was just 20 ETH. However, the community largely labeled the presale a “disaster.” Clanker used a presale contract based on an outdated version released earlier this year, allowing a whale to snipe the sale and secure 16 ETH (80%) of the allocation. Additionally, the presale had no per-wallet participation limits—a key factor in whales monopolizing tokens. In response, Romero noted the sniping address will only receive tokens 7 days later, and confirmed the next presale will be permissioned to ensure fairness. As of press time, HOUSE has a reported market cap of $1 million, trading volume of just $1.8 million, and 682 token holders.

Dec. 5 — The USPD protocol posted on X (formerly Twitter) that it had faced a critical security breach. The attacker exploited the **CPIMP (Contract Pre-Deployment Insecurely Managed Proxy)** method to preemptively seize control of the proxy contract’s administrator permissions during deployment. Disguised as the audited contract version, the attacker lurked for months before launching the attack—minting ~98 million USPD tokens and stealing ~232 stETH. In a statement, the USPD team clarified the incident did not stem from a smart contract logic flaw. They have reported the relevant attacker addresses to major centralized exchanges (CEXs) to freeze the funds. The team also offered a bounty: if the attacker returns 90% of the stolen assets, they may keep 10% as a reward.
