Address poisoning works by cluttering your transaction history with fake entries, tricking you into sending funds to a scammer’s address by mistake. Address poisoning exploits behavior, not private keys. Attackers manipulate transaction history and rely on users mistakenly copying a malicious lookalike address. Cases such as the 50-million-USDT loss in 2025 and the 3.5 wBTC drain in February 2026 demonstrate how simple interface deception can lead to massive financial damage. Copy buttons, visible transaction history and unfiltered dust transfers make poisoned addresses appear trustworthy within wallet interfaces. Read more
OpenAI said it is becoming increasingly important to evaluate the performance of AI agents in “economically meaningful environments” as their adoption grows. OpenAI has launched a new benchmark that evaluates how well different AI models detect, patch, and even exploit security vulnerabilities found in crypto smart contracts. OpenAI released the “EVMbench: Evaluating AI Agents on Smart Contract Security” paper on Wednesday, in collaboration with crypto investment firm Paradigm and crypto security firm OtterSec, to evaluate how much the AI agents could theoretically exploit from 120 smart contract vulnerabilities. Anthropic’s Claude Opus 4.6 came out on top with an average “detect award” of $37,824, followed by OpenAI’s OC-GPT-5.2 and Google’s Gemini 3 Pro at $31,623 and $25,112, respectively. Read more
A drop in Solana’s dApp revenues, along with limited institutional and retail investor interest, adds vulnerability to SOL’s $78 support. Key takeaways: SOL is struggling to hold $80 as a 75% drop in futures' open interest shows that traders are heading for the exits rather than opening new bets. Solana remains heavily dependent on retail and memecoin activity, while Ethereum maintains its lead in high-value decentralized finance. Read more
Bitcoin’s “short-term holder stress” metric has fallen to lows not seen since 2018, suggesting the market has capitulated and possibly bottomed. A key Bitcoin (BTC) on-chain metric is flashing its most extreme capitulation signal since 2018, hinting at a potential cycle-low setup. Bitcoin’s short-term holder stress has dropped to its lowest level since the 2018 bear market bottom, according to new on-chain data from Checkonchain. The Short-Term Holder (STH) Bollinger Band metric shows the oscillator falling into its deepest oversold territory in nearly eight years. Read more
The Base engineering team said the protocol would remain open-source and encouraged developers to continue building unique implementations. Base, a decentralized Ethereum layer-2 scaling network, said Wednesday that it is transitioning from running on L2 blockchain protocol Optimism’s tech stack to running on its own, unified software architecture. Launched in 2023 as an Optimism chain, Base is shifting to its own tech stack to reduce dependencies on external service providers and shorten the time it takes to ship new upgrades, according to an announcement from Base. The team said: The transition is also expected to simplify the Base network’s sequencer, which helps network validators to order transactions, the Base engineering team said. Read more
