ENS PG Builder Grants

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.

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.

Women in DeFi (WID) is a non-profit increasing the participation of women and girls in blockchain and decentralized finance across Africa. We close the gender gap in emerging tech through accessible education, mentorship, and community-driven opportunities.

Our flagship programs, Skill-Up training and Intro to Web3, equip women with blockchain skills and industry knowledge to secure careers, launch projects, and contribute to the Web3 ecosystem.

Through online learning, community events, and outreach to underserved areas, we’ve impacted over 7,000 women and aim to reach 2 million, focusing on rural and low-income communities. We foster understanding, create opportunities, and nurture leaders, ensuring women shape the decentralized future.

Educational Impact from participants has been overwhelmingly positive and You can access our 2024 Annual Report here: https://drive.google.com/file/d/1SAbv76eM6S4StD1dm5hqQVWlJgLjw5rf/view?usp=sharing

Dev3pack is a global developer fellowship for women+ and student developers coming from Web2, who want to become Web3 developers > builders > founders only in the Ethereum ecosystem. All developers have already been carefully selected before integrating the dev3pack program after a selection process using Speedrun Ethereum. We care about onboarding and follow all developers closely to become a real builder in the ecosystem. We are organizing many bootcamps, study groups, hackathon preparation week, and encouraging open source contributions. We are already supported by EF, PSE, Base, Lisk, Morpho, Ledger, Uniswap, Chainlink, Farcaster, EigenCloud and other key players in the ecosystem.

This grant would help cover costs for the fellowship with education, dev3pack village program residency, and dev3pack long-term growth in LATAM, Africa and SEA. We recently launched dev3pack LATAM.

Hi all! We're building Revoke.cash, the number 1 platform to manage your token approvals and stay safe on Ethereum and over 100+ other EVM chains. We've helped millions of users stay safe and prevented at least $140M potential losses in the past 5 years, all while being a 100% free and open source public good.

This year we've already released several new features, such as Abstract Global Wallet Sessions, Coverage and Delegations dashboard. On top of that we were the FIRST app on Ethereum to support EIP7702-based batch transactions, immediately when the Pectra update went live. We have some additional plans this year that are outlined in the milestones below.

We initially applied for large grants but as we've already received a large grant in 2024 as well, we're reapplying for a small grant instead.
