Pre-ERC: Agent Pre-Sign Risk Report

Pre-ERC: Agent Pre-Sign Risk Report is a draft Ethereum Magicians proposal for an EIP-712-signed report that a risk source, identified by an ERC-8004 identity, returns about one unsigned request. It carries typed findings on tokens, approvals, addresses, payments (x402) and texts, and each finding is marked read or not read. It has no score or verdict, so the consumer applies its own policy. The author's live implementation, toll, runs on Robinhood Chain.

Pre-ERC: Agent Pre-Sign Risk Report

Pre-ERC: Agent Pre-Sign Risk Report is an Ethereum Magicians draft for a signed, typed report that a risk source returns about one unsigned agent transaction. The report is bound to the request by a digest and signed with EIP-712 by an ERC-8004 identity. Findings cover tokens, approvals, addresses, x402 payments and texts, each marked read or not read, with no score or verdict. The toll service runs it live on Robinhood Chain.

DBHub, a database MCP server, had a read-only mode bypass in its SQL check. The check treated every `--` as a comment, but MySQL only starts a comment when whitespace follows it. A hidden write statement could therefore still run, and a prompt injection could trigger it. Fixed in version 0.22.6. Replies say enforcement belongs in database grants and that parser tests need to be dialect-specific.

Hyperflow H3 is Video Rebirth's 8-step LoRA for MiniMax H3, released in September 2026 with open weights. Artificial Analysis ranks it #5 on AA-Video-I2V v2.1 and #3 on AA-Video-Editing v1.1, ahead of MiniMax H3 (768p). It costs $9.00 per minute for Image to Video and $18.00 for Video Editing at 1088p, under half of Dreamina Seedance 2.5 ($34.12 and $40.82). The thread gives per-capability and per-use-case breakdowns.

Pre-ERC: x402 Payee Verification for ERC-8004 Agents

Pre-ERC draft on Ethereum Magicians that binds the x402 payTo address to an ERC-8004 agent's registered agentWallet, directly or through an EIP-712 payee delegation (ERC-1271 for contract wallets). It lists eight fixed checker outcomes and requires the resource origin to appear in the registration file. On Robinhood Chain (28 October 2026), 5,575 of 20,046 agents answered with x402 requirements, and only 5 used their agentWallet as payTo.

ERC-8478: x402 Payee Verification for ERC-8004 Agents

ERC-8478 is a draft Ethereum standard that binds the payTo address in an x402 payment requirement to the seller's ERC-8004 agent identity. A payer compares payTo with the registered agentWallet, or accepts an EIP-712 payee delegation signed by it, and checks that the origin is listed in the registration file. On Robinhood Chain, 5 of 5,575 x402-responding agents had payTo equal to agentWallet (28 October 2026).

ERC-8478 is a draft Ethereum standard that binds the x402 payTo address to an ERC-8004 agent's identity, to stop payee redirection by a hijacked domain, proxy or injected tool result. A payTo must equal the agentWallet or carry an EIP-712 delegation signed by it, and the origin must be listed in the registration file.

EIP Draft: Permanent EOA Delegation Opt-Out (disable EIP-7702)

Discussion thread for a draft Core EIP that lets an Ethereum EOA permanently disable EIP-7702 delegation. A type-4 set-code transaction with an empty authorization list, destination equal to sender and zero value installs the 0xef0200 marker for 33500 gas. Later authorizations, including clearing to the zero address, are skipped. It does not protect against private-key compromise. Open questions cover the prefix, a dedicated transaction type, gas pricing, and EIP-8151 interaction.

Thread by Elvis Saravia (omarsar0) summarising an Anthropic-led paper on pretraining data poisoning of CLI agents. Poisoning 0.1% of pretraining data planted a remote code execution backdoor in Qwen3 models (0.6B, 1.7B, 4B) trained from scratch. It survived SFT, DPO and RL, and fired on about 92% of triggered prompts at 4B. At a 0.0005% poison rate (about 2,500 documents) it still fired on 1.4% of prompts.

Anthropic Cracking Down on Video Game Rewrites

A tweet from chasmmmmmmmmmmm says Claude Code received a new rule around 27 October 2026, delivered from Anthropic's servers under the flag "tengu_heron_brook", with no setting to disable it. The quoted rule allows original games, genre games and games from the user's own designs and assets, but forbids recreating a specific existing game, even if renamed. The post asks whether this ends game rewrites and modding, and gives no verification beyond the quoted text.

Anthropic did not develop that version, and other extensions are not affected. Users of Claude Code in Cursor are told to update to version 2.1.314. The post adds that marketplaces need publisher verification and package integrity checks. It gives no technical detail on the payload.
