Brief summary of the project, its achievements, and overall impact on the Arbitrum ecosystem:
The project “Solidity Training Course – Web3 PE (2nd Edition)” was a 24-hour practical immersion held over three days, aimed at training professionals, students, and enthusiasts in the fundamentals of Web3 and smart contract development using Solidity. The initiative was a core component of the Web3 PE – 2nd Edition event, held in Pernambuco, Brazil.
The main achievement was the graduation of 34 new developers, with a strong focus on inclusion — 6 of whom were women (approximately 17.6% of the cohort). The course concluded with the delivery of open-source smart contract prototypes — the “Projeto Moura” — publicly available in the GitHub repository, demonstrating the technical proficiency acquired by the students. The impact on the Arbitrum ecosystem lies in creating a new cohort of developers ready to build and deploy on the Arbitrum One/Nova network, following the course structure.
Explain the impact of the funding obtained through this grant:
The Arbitrum D.A.O. grant was essential to delivering a high-quality, fully free course for all participants. The funding covered key infrastructure, educational materials, photo/video coverage, and logistics costs, ensuring an immersive and professional learning environment. More importantly, Arbitrum’s support elevated the event’s visibility, attracting a broader audience (the Web3 PE event reached over 1,200 attendees) and validating the importance of Web3 education in Brazil’s Northeast region. This positioned Arbitrum as a key enabler of developer capacity-building in emerging markets.
2. Performance Against KPIs
The project’s KPIs focused on Reach & Inclusion, Technical Production, and Integration with Arbitrum.
Results exceeded expectations in both technical output and overall reach, as detailed in the table below — based on data from the course’s public repository:
| Dimension | Projected Metric (Estimate) | Actual Result | Comment |
|---|---|---|---|
| Reach & Inclusion | 25–30 graduates | 34 graduates | Surpassed the target for developer training. |
| Inclusion | 10% women | 6 women (≈17.6%) | Exceeded the gender inclusion goal. |
| Technical Production | Repository with 1 final prototype | Repository with 18+ prototypes | Each participant delivered their own prototype (“Projeto Moura”), resulting in a robust open-source repository with 186 commits. |
| Integration with Arbitrum | Framework for deployment on Arbitrum | Projects structured for portability to Arbitrum One/Nova | Deployment guides and code structure were delivered, preparing students for the next step. |
| Event Reach | 500–800 participants (Web3 PE) | 1,200+ attendees (total audience) | The course was part of a larger event that significantly exceeded expectations. |
| Social Reach | 50,000 impressions | 109,000+ views (2nd edition content) | Social media reach more than doubled initial estimates, showing strong engagement. |
3. Qualitative Impact & Community Feedback
Most significant non-quantitative outcome:
The most meaningful result was the creation of a talent pipeline focused on Solidity and open-source development — a group of graduates now ready to contribute to the Arbitrum ecosystem.
The course repository, containing multiple individual projects, serves as a verifiable code portfolio for each of the 34 graduates, facilitating their entry into the Web3 job market.
Additionally, the inclusion of a “Student Comprehension Report – Before and After” directory in the repository (line 329 of the README) provides qualitative evidence of participants’ learning progress and skill development throughout the program.

Full Event
. Financial Summary
Description of how the grant funds were utilized:
The grant funds were fully allocated to ensure the quality and reach of the Solidity Training Course, which was offered free of charge to all participants. The main expense categories were as follows:
| Expense Category | Approximate Percentage | Description |
|---|---|---|
| Infrastructure & Logistics | 40% | Equipment, learning materials, and coffee breaks for the 3-day course. |
| Content Production & Documentation | 30% | Professional photo and video coverage, editing of content for social media, and project documentation (including the GitHub repository). |
| Graphic Materials & Communication | 20% | Creation and printing of graphic materials, event signage, and promotional campaigns. |
| Coordination & Support | 10% | Technical assistance and team coordination for course execution. |
Explanation of any significant differences compared to the original budget plan:
There were no significant deviations in the use of funds. The budget was executed as planned, with a clear focus on maximizing the student learning experience and the event’s overall reach. The allocation of resources to Content Production and Documentation proved essential for generating completion evidence and promotional materials, which directly contributed to the project’s high social reach (109,000+ views).
5. Future Plans & Continued Ecosystem Alignment
Next steps for the project post-grant:
The immediate next step is the deployment of the prototypes developed by students onto the Arbitrum network. The repository already includes detailed deployment instructions for both Arbitrum Sepolia (testnet) and Arbitrum One (mainnet).
How do you plan to expand on the original idea?
The expansion will take place across three main fronts:
- Micro-Bounties:
Establish a micro-bounty pool to incentivize the 34 graduates to deploy their projects on Arbitrum, turning their prototypes into fully functional dApps. - Continuous Engagement:
Encourage graduates to participate in Arbitrum hackathons and bootcamps, and organize office hours with Arbitrum DevRel members and ambassadors for mentorship and guidance. - Infrastructure Support:
Seek infrastructure credits (RPCs, explorers, developer tools) to lower entry barriers for new developers entering the Arbitrum ecosystem.
How do you plan to remain engaged with the Arbitrum ecosystem?
Web3EduBrasil will continue to promote Arbitrum as the network of choice for smart contract development in its future courses and events. The ongoing engagement will be maintained through:
- Education: Integrating dedicated modules on Arbitrum’s architecture and tools into upcoming course curricula.
- Community: Showcasing successful graduate projects built on Arbitrum across our communication channels and at the Web3 PE event.
- Proposals: Submitting new proposals to the D.A.O. to expand the course model to other regions of Brazil, always focused on developer enablement for the Arbitrum ecosystem.
Impact of the grant on attracting future funding or partnerships:
The support from Arbitrum D.A.O. serves as a high-value validation mark, demonstrating Web3EduBrasil’s ability to deliver impactful and high-quality educational programs. This credibility is instrumental in attracting new partners and funding opportunities — both from other DAOs and from companies within the broader Web3 industry.
6. Additional Remarks
We would like to highlight the quality of the open-source code produced. The course repository serves not only as educational material but also as a hub of functional projects. With 15 stars and 2 forks on GitHub, the project already demonstrates organic community traction, indicating long-term value and relevance.
Web3EduBrasil is committed to using this successful case as a model for future Web3 education initiatives in Brazil, further expanding the impact of developer training and ecosystem growth.
