On Thursday’s ACD call, Ethereum core developers reaffirmed their intent to ship Full EOF (EVM object format) with the Fusaka fork alongside the PeerDAS main driver. (Ipsilon wrote up a thorough review of the options, with Full EOF referred to as “Option A.”)

EOF is a major overhaul of the EVM that aims for long-term optimization, safety and modularity of Ethereum’s execution engine.

Its scope has stirred controversy. Felix (from the Geth team) backed the more moderate Option D, putting him slightly at odds with fellow Geth college Lightclients.

From outside the client teams, Pascal Caversaccio voiced strong opposition, following up on his published critique: “EOF: When Complexity Outweighs Necessity.” His main claim: No application developers are asking for EOF, and its rollout risks alienating the broader dev community.

Despite this, EF staff —  including Piper Merriam and Ansgar Dietrichs, as well as client teams like Besu and Erigon — stood behind Full EOF. Their reasoning: It’s a clean structural reset, demanded by compiler authors, and backward-compatible for developers preferring the legacy EVM.

Tim Beiko acknowledged the complexity, but noted it emerged from years of iterative work. “We can’t decide not to do something just because it’s complex,” he told participants on the call.

“Long live Full EOF,” cheered Merriam.

So EOF is coming. For developers, the negotiation phase seems over, and the upgrade’s next chapter will focus on implementation and testing.

Figure, founded by former SoFi CEO Mike Cagney, has emerged as a leader in onchain RWAs, with ~$17.5B publicly tokenized. The platform’s ecosystem volume is growing ~40% YoY as it expands beyond HELOCs into student loans, DSCR loans, unsecured loans, bankruptcy claims, and more. Operationally, Figure cuts average loan production cost by ~93% and compresses median funding time from ~42 days to ~10, creating a durable speed-and-cost advantage.
