📦 Thread 4 — bigger contracts, same address everywhere. Thread 3: native ETH finally logs. Today: deploy larger bytecode + rely on Nick's CREATE2 factory. EIP-7954 + EIP-7997. 🧵

And we are live. This will change the way you can reliably reason with your agent about future #Ethereum protocol changes. So what can you ask?

Onwards to complete our #Glamsterdam explorations set before we translate everything for the robots 🤖 along MCP launch (see below on a date 📅): New #FYP exploration around EIP-8037 to "feel" why 21,000 gas is not necessarily 21,000 gas "as it used to be"anymore, once the hardfork kicks in on #Ethereum. Are you a wallet/infra provider/dev and affected by this? We would love to hear how! 🙏 Drop ↓

We have a launch date. 5–9 October 2026 hosted MCP at mcp.feelyourprotocol.org Feel Your Protocol is the EVM oracle for the upcoming Glamsterdam hardfork — exact simulations of execution-layer rules not yet on mainnet. Today: the website. October: your agent. roadmap.feelyourprotocol.org…

📜 Thread 3 — native ETH finally logs. Thread 2: every block commits what state it touched. Today: every native ETH move emits a log you can index. EIP-7708. 🧵

More gotchas: 7954 — bigger contracts = more deploy gas + state bloat; still capped at 64 KiB. 7997 — factory must exist in your genesis/test pre-state; mainnet already has it. Experimental — not production. Next: builder requests (EIP-8282). 🚀 [ END OF THREAD ]
