We published a status update on Core Solidity: what the language can do today, what is still missing, what the community told us, and what comes next.

@0xYamashi Video made by @0xYamashi. Huge thanks!

Every transaction your wallet sends, held until you check it.

TxGate: a local RPC gate that decodes the signed tx itself, flags unlimited approvals, and broadcasts only after you approve.

我为交易安全软件 TxGate 制作了一段视频，结果显得非常粗糙。 要制作出高质量的视频，必须花时间去学习相关的制作技艺才行。

@0xYamashi The App use Tenderly to simulate transactions (now)

Years ago my private key was stolen. Ever since, I haven't fully trusted any wallet, software or hardware.

So I built a small CLI that held my wallet's eth_send* calls until I'd verified each tx by hand.

Now AI has rewritten it with a UI: TxGate

A local RPC proxy. Point your wallet's RPC at http://<your IP>:8545/<chainId>

1. Reads pass straight through to your Alchemy/Infura node
2. eth_sendRawTransaction is held; TxGate decodes the signed tx itself, never trusting the wallet/dApp UI
3. Reject → wallet gets error 4001

@VitalikButerin Why not make each multisig owner an EIP-1271 contract whose isValidSignature checks both an ECDSA sig and a PQ sig (e.g. hash-based)?
The only cost I see is that each signer has to keep two keys. Seems simpler than rotating keys after every operation?

BREAKING: bitcoin sent via apple's "find my" mesh network

possibly the most absurd medium to send bitcoin yet

a small device convinces nearby iphones to transmit tiny amounts of data with cashu ecash to the recipient.

without any internet connection.

magic i̶n̶t̶e̶r̶n̶e̶t̶ money.

I’ve always loved Theremino Spectrometer, a spectrometry app written in VB.
My biggest frustration: it only runs on Windows.

With AI, I managed to build a web-based fork of it.
The last year has completely changed how software gets written

Fun with a cheap Spectrometer - Looking at a MV Lamp running.

400W Mercury Vapour Lamp running after 6 minutes.
Amazing the number of long wavelength spikes.

Application download for Theremino Spectrometer – version 3.1

@zengjiajun_eth @lurenbian Got it, this bug is reproducible. I’ll figure out what’s causing it.✌️

A Tampermonkey userscript called BlockX — adds a "block" button to every reply on X
One click to block bots/spam accounts, no more tapping "More" → "Block"
Simple, open-source code — no need to worry about the security risks of closed-source extension

3. Native understanding of market structure, resolution criteria, and liquidity.
4. Iterative analysis, with the ability to turn past Polymarket outcomes into part of the agent's memory.

"Skill for Polymarket" Is Doomed to Fail!

The "Skill" approach tries to bolt domain expertise onto a general-purpose system. For something like Polymarket — where the cost of being wrong is denominated in real money — this is a dead end.

[Suhail Kakar @SuhailKakar]

new improved polymarket docs are live!

https://t.co/e3YBiR46Be

mcp + agent skills included. drop the link into cursor, claude, whatever - your agent learns and builds on polymarket directly

next up: builder fees, sdks, and more

[Jayden 🎚 @jayden_sudo]

What we actually need is to apply the Claude Code architecture — a purpose-built agent with deep internal prompt engineering — to Polymarket:

1. Built-in web scraping and data retrieval.
2. 100+ prompts tailored to different prediction domains (politics, crypto, sports ..)
