Supporting the Launch of Polkadot Hub: Campaign to Onboard Web2 Developers in LATAM and Beyond

Introduction

Polkadot’s success depends on its developer base, a point raised in the Polkadot Growth Strategy and the Polkadot Hub Launch Update from the Business Development Group. Instead of focusing on Web3 developers from other chains, we suggest targeting Web2 developers interested in new areas, which fits the Growth Strategy’s mention of expanding adoption and the Hub’s plan to grow the ecosystem.

We’ve been running a Polkadot Rust Course throughout 2024 funded by the grant “#627 Proposal for Polkadot OpenGov Funding: WEB3DEV Bootcamp for Rust and Pallets Learning”. The full report for the delivery of the last proposal can be found in this link. After engaging with students and analyzing our data and efforts, we’ve unlocked some key insights that shape the present proposal.

Weever (formerly WEB3DEV) has been actively growing Polkadot’s presence in Latin America through technical education and strategic collaboration with the Polkadot Blockchain Academy. Our Rust Course cohorts and live sessions have helped onboard students into the ecosystem, preparing them for real-world learning experiences such as the PBA Campus and, more recently, PBAx through dedicated prep content and promo code access.

Now, we are focused on expanding entry-level content to make Polkadot more accessible, especially as other ecosystems with easier onboarding are gaining space in Brazil. The Polkadot Hub offers a strategic opportunity to attract new developers by fostering relationships and creating clear onboarding pathways. Our goal is not only to onboard developers but to prepare them to go deeper, gain expertise, and become long-term contributors to the ecosystem.

At the same time, we are pivoting all our EVM-focused content, previously aligned with networks like Polygon, to support the Polkadot Asset Hub. With over 3,500 students, a 10,000+ developer community, nearly 1 million in reach, and a strong multilingual presence, Weever is well-positioned to drive this transition and help scale Polkadot adoption across LATAM and beyond. We have also expanded beyond grassroots initiatives, reaching institutional levels such as the Central Bank, ICTs, companies, city halls, and universities, building the foundation to introduce Polkadot at scale.

Problem Statement

In LATAM, a region with a growing tech scene, many Web2 developers are curious about blockchain but lack accessible, beginner-friendly resources to explore Polkadot. Local agents such as community leaders, educators, and institutions do not have the tools or structured content needed to onboard these developers effectively. Our marketing and media efforts for the Rust Course initially targeted Web3 developers with prior experience, but we found that the most engaged students were those with no previous knowledge of blockchain technology. This revealed a significant opportunity to bring Web2 developers into Polkadot, rather than focusing solely on established Web3 developers. Meanwhile, after years of projects lacking a true Web3 ethos, like gambling and memecoins, seasoned builders are asking, "What is this all about?" and "What are we really building for the world?" We believe Polkadot's emphasis on decentralization and governance provides the answer, but Web2 developers need clear guidance to understand its importance.

Proposed Solution

To address the lack of accessible resources for Web2 developers in LATAM curious about blockchain, while also engaging Web3-experienced developers seeking purpose, we propose a comprehensive onboarding journey to integrate both groups into Polkadot’s Web3 ecosystem. Our primary focus will be onboarding Web2 developers with little to no blockchain experience, while providing Web3 developers with meaningful applications that align with Polkadot’s decentralized, governance-driven ethos.

We will guide developers through hands-on tutorials, activities, and content designed to build decentralized finance (DeFi) infrastructure from scratch, including decentralized exchanges (DEX), borrowing and lending platforms, staking systems, voting mechanisms, and other Web3-native solutions. For Web2 developers, these resources will introduce Polkadot’s flexible, open-source infrastructure as a foundation for impactful applications. For Web3-experienced developers, we’ll highlight how Polkadot’s transparent governance and decentralization enable projects that move beyond speculative trends like gambling or memecoins, answering their call for purpose-driven development.

To fully support this transition, we will migrate all our existing EVM-focused content and courses, which were previously aligned with other chains, to Polkadot’s Asset Hub. This ensures continuity for our current users while unifying all our educational efforts under Polkadot’s infrastructure.

To reduce friction and keep momentum, we’ll pair this content with weekly livecoding sessions on Polkadot’s official Discord, offering direct support and helping developers overcome blockers in real time. Our efforts will feed into Polkadot’s broader training ecosystem, creating a pipeline of skilled builders in LATAM. We will also collaborate with other agents in the ecosystem to help distribute this content and expand its reach. To sustain long-term engagement, we’ll run study groups, hackathons, and mentoring, fostering a strong, supportive community for both newcomers and experienced developers.

The entire journey will be subtitled in Portuguese and Spanish and will remain available online as a long-term resource. We will continue to promote it and make it accessible to all Polkadot agents and partners interested in using it for their own onboarding or awareness campaigns

Objectives

Our initiative aims to onboard Web2 developers with no blockchain experience into the Polkadot ecosystem within a 12-month period, leveraging WEB3DEV’s proven community-driven education model to drive adoption of the Asset Hub and support the Polkadot Hub launch in LATAM. Here are our specific goals:

Update EVM Tutorials for Asset Hub by Q3 2025
Modify our existing EVM online courses to use Polkadot Asset Hub (instead of Polygon) by Q3 2025, ensuring Web2 developers can seamlessly transition to Polkadot.
Run Weekly Livecoding Support Sessions Focused on Solidity and Web3 Integration: Host weekly livecoding sessions on the official Polkadot Discord, dedicated to helping developers with Solidity and Web3 integration on Polkadot, including topics like deploying contracts to Asset Hub, using tools like ethers.js, and bridging EVM knowledge to the Polkadot ecosystem.

Core Benefits

Through practical tutorials, engaging content, weekly livecoding support, and a focus on Polkadot’s governance advantages, we aim to turn LATAM’s untapped developer talent into a thriving community of Polkadot builders. Here’s how this delivers value to the ecosystem:

Opening Polkadot to Web2 Newcomers: Web2 developers familiar with centralized platforms like AWS or GCP often lack exposure to blockchain. While Web3-experienced developers seek purpose-driven projects.Our tutorials start from scratch, guiding them through projects like deploying a DEX or a full DApp on the Westend network. For Web3-experienced developers, we’ll provide advanced tutorials on governance-integrated DApps, to leverage their expertise and align with their desire for impactful development. This dual approach supports the Polkadot Hub’s mission to expand participation, welcoming diverse talent to build on the Asset Hub.
Showcasing Polkadot’s Unique Value: Our content contrasts Polkadot’s transparent, open-source infrastructure with Web2’s opaque systems, highlighting why it’s a better choice for developers. Animated explainers and examples will demonstrate how Polkadot Hub and the Asset Hub enable decentralized apps and asset management with interoperability and community control.
Turning Governance into a Developer Advantage: Polkadot’s governance system is a key draw, and our tutorials will teach developers how to use it. Covering OpenGov, Conviction Voting, the Treasury System, we’ll show them how to influence the network, propose upgrades, or secure funding.
Growing Skills from Novice to Expert: With no prior knowledge assumed, our hands-on tutorials—like building an NFT smart contract, a DeFi staking contract, or a DAO—build foundational skills. A clear path to advanced resources like the Polkadot Blockchain Academy then fosters expertise.
Support to Accelerate Builder Success: Weekly livecoding sessions on the Polkadot Discord will offer consistent, practical guidance to developers building with Solidity and Web3 tools on Asset Hub. This initiative reduces friction for newcomers, accelerates project development, and increases retention by offering immediate help within the ecosystem.
Multilingual and Broadly Accessible: All content will include Portuguese and Spanish subtitles, making the onboarding journey accessible across LATAM and removing language barriers for adoption.
Reusable by Ecosystem Partners: The full content will remain online and openly available for use by Polkadot agents and partners in their own onboarding journeys and campaigns.

In summary, our initiative transforms Web2 developers into Polkadot contributors through a complete onboarding journey, combining hands-on tutorials, a clear learning path, and a focus on governance as a unique strength. Weekly livecoding sessions on the official Polkadot Discord will provide ongoing support, helping builders overcome blockers and stay engaged. All content will remain online with Portuguese and Spanish subtitles and be available for ecosystem partners to reuse. Together, these efforts drive Asset Hub adoption, fuel the Polkadot Hub’s expansion, and position Polkadot as the top choice for LATAM’s emerging developers.
