01 02 Ethereum proposes native transaction assertions, with frame-transaction opcodes that let contracts inspect net state after execution.03 Pump-and-Dump meets Honeypot Tokens: Detection and Analysis of Telegram Bait-and-Trap Schemes arxiv.orgPaper on Telegram-run pump-and-dump honeypots, with 3,677 cases and a pre-buy simulation detector, because rugs needed analytics.04 Uniswap v4 gets a regulated Japanese DeFi venue, custom pools plus hooks for AML/CFT and investor checks, not just another DEX clone.05 A Systematization of Knowledge on DeFi Vaults: Architectures, Curation Mechanisms, and Strategy Design arxiv.orgAnother taxonomy paper, this one actually models the curator control plane around vault strategy/risk selection.06 Making Duplicate Reimbursement Unrepresentable: A Verified Ethereum E-Invoice System for Humans and AI Agents arxiv.orgA verified Ethereum e-invoice model that makes duplicate reimbursements impossible, which is a nice change from policy docs.07 SmartMemory: Detecting On-chain-off-chain Communication Inconsistency for Smart Contract via Memory-based Agent arxiv.orgSmartMemory adds a memory-based agent and semantic canonicalization for OFCI bugs, instead of the usual brittle pattern hunt.08 Web3 tries to leash AI wallet bots with smart-contract wallets, spending caps, whitelists, and session keys.09 A Lightweight Ethereum Voting Prototype for Hospital Ethics Committees with Receipt-Based Inclusion Verification arxiv.orgIt proves hospital ethics voting on Ethereum, then admits it's only pseudonymous and not coercion-resistant, which is the point.10 On-chain payee registry binds Japanese company IDs to stablecoin payout addresses, with World ID approvals and freeze windows.11 X post roundups Ethereum protocol AMA, privacy workshop, and enterprise news, because one thread apparently needed all of it.12 Last revealer attacks get a full writeup here, plus a commit-reveal Solidity/Polygon RNG prototype and testnet cost numbers.13 AI agents get leash math: spending caps, whitelists, session keys, multisig approvals, and revocation on-chain.14 Need a guided intro to building on Dusk, with Rust contracts, JS dApps, and PLONK circuits, or is that too easy?15 Nostra exploit postmortem, a manipulated NSTR price feed on Starknet let $3.5M be borrowed against fake collateral.16 Why another account opcode? SETCODEFROM points a code hash at deployed code and tries to clean up the EOA vs contract mess.17 Postmortem of the Tectonic Cronos exploit, where donation-inflated tTONIC and DEX price games funded a $120M borrow.18 Solidity Meets LLMs: A Transformer-Based Approach to Smart Contract Vulnerability Detection arxiv.orgPaper on BERT-based Solidity vuln detection, with a labeled dataset and 92% F1. More code reviewing, now with transformers.19 Blockchain-Enabled Artificial Intelligence and AI Agents for Secure Data Sharing and Cybersecurity Applications arxiv.orgBlockchain shows up as the glue for AI security, in a survey that mixes provenance, anomaly detection, and patching pipelines.20 Verifiable Computation with Trusted Execution Environments and On-Chain Digital Rights Tokens arxiv.orgTEEs plus on-chain rights tokens for private compute, so the data owner can sell approved jobs without handing over the data.
