At Phantom Zone (PZ) we work to make cryptographic primitives that are impactful to the world concretely efficient. Our desire is to drive forward the progress in these primitives, to reduce their overhead, and to make them widely accessible. It's with this lens we set our priorities.

One of our core goals is to design a practical & efficient construction of the encrypted computer. It's a computer that executes encrypted programs on encrypted inputs. It guarantees that it's memory and execution trace cannot be read. The only thing learnt is the output of the program.

The encrypted computer has numerous valuable use-cases for the ethereum ecosystem. For example, encrypted smart contracts ( i.e. smart contracts with private state ) and encrypted mempool. It also open a new paradgim for smart contracts design: smart contract with hidden secrets.

The primitives we work with are building pieces of the encrypted computer. But this does not mean that they are not impactful in their own right. In fact, it is while experimenting with these primitives (independently) that we figured that they can be composed together for something more powerful.

For the rest of the document, we'll outline different initiatives within PZ and how they are impactful to the ethereum ecosystem and beyond.

Imagine logging into Ethereum with just your fingerprint or Face ID - no WalletConnect popups, no browser extensions, no manual seed phrases. That's what multisigned enables.

multisigned is open-source key infrastructure that lets any developer host their own passkey-based authentication for Ethereum applications. Built for the social side of Ethereum where users want seamless login.

The innovation: client-side encryption means developers can run their own infrastructure without being able to read users' keys or hold them hostage. This eliminates vendor lock-in while keeping setup simple.

The protocol uses envelope encryption with WebAuthn PRF: a Key Encryption Key (KEK) from the passkey wraps a Data Encryption Key (DEK), which encrypts the vault containing the Ethereum seed phrase. Keys stay under user control while enabling cross-device access.

Why this matters: Developers today either (1) use clunky WalletConnect that kills conversion, (2) lock into vendors like Privy with licensing fees, or (3) depend on providers who control the infrastructure. multisigned gives every developer the option to run credibly neutral infrastructure themselves.

Standalone repository (https://github.com/attestate/multisigned) built for the entire ecosystem. Kiwi News is the first reference implementation.

We are a community-driven initiative to boost the Ethereum ecosystem in Mexico. Since 2022, Ethereum Mexico has been at the forefront of Ethereum's growth in Mexico, fostering education, community building, and innovation.

Our main project for this year is Ethereum México 2025, a four-day event with a 3-day hackathon, talks, workshops, a VIP dinner and networking. The event starts October 30th and ends November 2nd in Monterrey, Mx. It aims to inspire and empower the next generation of Ethereum enthusiasts to build a decentralized, equitable, and sustainable future. This event addresses a critical need in the Mexican Ethereum community for large-scale, local gatherings.

Connecting over 900 developers, students, entrepreneurs, investors, government officials and enthusiasts, Ethereum México 2025 in Monterrey will boost a community that believes in the power of decentralized technologies and Ethereum's potential to change the world. The core value proposition of our project is to unite, motivate, and empower the next generation of builders.

We want ENS to be part of this journey and to become a Sponsor of Ethereum México 2025. We are proposing an ENS hackathon track and we offer ENS benefits based on the tier of funding received, view details available here: https://ethmexico.org/ethereum-mexico-mty-2025/

Open L2 Bridge Reliability Toolkit is an open‑source web app, SDK, and CLI that makes L1→L2 transfers across Ethereum rollups reliable, transparent, and self‑custodial. Bridging today is fragmented: opaque fees, sequencer outages, and inconsistent behaviors create “stuck” transfers and duplicated engineering. Our chain‑agnostic toolkit standardizes fee estimation, message lifecycle tracking, and recovery (e.g., forced‑inclusion/redeem) across major L2s—launching with Arbitrum and OP Stack (Base/Optimism) and expanding to Scroll, Linea, Polygon zkEVM, Starknet, and more.

Existing work: a functioning MVP that submits Arbitrum retryable tickets, deposits to OP Stack chains, and detects/redeems unexecuted messages, built in Bun/TypeScript with `ethers` and `@arbitrum/sdk`. Code: (https://github.com/Dhaiwat10/force-inclusion-script).

Deliverables: a user‑friendly website with wallet connect, fee previews, and guided recovery; a small, typed SDK (estimate → send → status → redeemIfNeeded) for wallets/dapps; and a CLI for automation. The project is credibly neutral (permissive license), modular (connector interface so new L2s can be added by the community), and resilient (multi‑RPC fallback, typed errors, clear refund surfaces). Impact: fewer failed/stuck transfers, lower support burden, and faster L2 adoption across the entire Ethereum ecosystem through consistent UX and reusable, open standards.

This project is a plug-and-play protocol that streamlines hackathon bounty distribution by using smart contracts to hold funds securely, enable joint approval of winners, and allow direct claiming by participants. It ensures transparent, reliable, and automated payouts while integrating easily with existing hackathon platforms.

Hackatsuon is a two-week residency and hackathon in Kesennuma City, a rural port town of 60,000 people six hours from Tokyo, heavily hit by the 2011 earthquake. The city has strong resilience and close ties between nonprofits and the government, but, like many rural areas in Japan, it faces severe depopulation. Expanding “relational population”—people meaningfully connected to the community—is a key priority.

Hackatsuon is organized with Kesennuma City, with cooperation from young municipal officers exploring how blockchain can serve daily life. I have led the project from concept to execution. For five years I served as Executive Director of Women’s Eye, providing IT training for women without computers and supporting vulnerable groups, while exploring how decentralized technologies could address social challenges.

With application outreach partnered with Kismet Casa, we received 30 applications. Ten participants from over five countries—builders with public project experience and strong motivation to collaborate with municipalities—are self-funding travel to Japan to co-create with a local government.

On Oct 13, a Demo Day & Reception with the mayor, local stakeholders, students, citizens, and media (~100 people) will showcase ENS as digital IDs and residency certificates, linking a rural community to the global ecosystem.

ENS support will help share these use cases as models inspiring developers and civic communities worldwide.

Research thread: https://discuss.ens.domains/t/ens-research-namechain-ensip-19-multichain-interop/21392

This grant recognizes work already delivered on ENS v2 and Namechain research, convened in partnership with Kernel and Nick Johnson (ENS founder). I organized a research session and authored a comprehensive forum thread analyzing open design questions around ENSIP-19 (multichain primary names), CCIP-Read (EIP-3668), migration policies, event/API discoverability, and security trade-offs.

The thread documents:

→ Key mechanisms and standards (ENSIP-19 + CCIP-Read).

→ Limitations of ENSv1 and how ENSv2 addresses them.

→ Trade-offs between interoperability vs. chain-specific implementations.

→ Migration risks (finality windows, auto-clearing L2 resolvers).

→ Renewal policies under the Name Wrapper.

→ Security and UX safeguards (address poisoning, audits, formal proofs).

→ Open research questions across protocol design, security, and identity.

This work surfaces the critical governance and design choices that will shape ENSv2 adoption, offering a structured foundation for further ENSIP development and community decision-making.

Hi team,

EVM Tools is a collection for dev tooling for web3 developers, that currently offers a comprehensive suite of 22+ tools designed to ease the development of web3 apps on EVM chains. Tools like EIP-712 and ERC-191 that standardize the handling and signing of structured data, bit manipulation and transaction decoders etc. to help in debugging. There are many such utilities that further support the developers by offering versatile, user-friendly tools for a variety of smart contract development tasks. As part of this grant, we want to build a playground for EIP-7702, that will help understand this smart account standard. At the same time, we will be improving the overall experience of existing tooling.
