Friend.tech was a SocialFi application launched on Coinbase's Base L2 in August 2023 that allowed users to buy and sell tokenized 'keys' (shares) of social media influencers. The platform suffered a wave of SIM-swap attacks draining at least 343 ETH from users, exposed wallet addresses of 101,000 users via an API data breach, launched its FRIEND token in May 2024 which collapsed 98% within months, and was ultimately abandoned by its pseudonymous founders in September 2024 after they extracted approximately $44 million in protocol fees.

Wasabi Protocol is a decentralized perpetual futures and leveraged trading platform for memecoins and long-tail assets, deployed on Ethereum, Base, Berachain, and Blast. On April 30, 2026, the protocol suffered a critical multi-chain exploit in which a compromised admin deployer key was used to execute malicious UUPS proxy upgrades across core contracts, draining over $5 million in user funds. Security firm BlockSec reported that the attacker's wallets had been funded via Tornado Cash, and on-chain investigator ZachXBT publicly criticized the protocol for single-EOA admin control, absence of a timelock or multisig, and alleged misappropriation of project funds on influencer marketing.

KAITO is the native token of Kaito AI, an AI-powered 'InfoFi' (information finance) platform built on Base blockchain, founded by former Citadel quantitative trader Yu Hu and launched in February 2025. On March 15, 2025, both the official Kaito AI X account and Yu Hu's personal account were compromised by hackers who spread false claims of wallet breaches while simultaneously holding short positions on KAITO, netting an estimated $1 million in profit from the manufactured price panic. The platform faced additional scrutiny from blockchain investigator ZachXBT over alleged AI bot spam incentivized by its Yaps reward system, which was ultimately sunset in January 2026 after X revoked API access to all InfoFi applications.
