JoinArc provides self-sovereign identity infrastructure for Web3, enterprises, and individuals.
Building the future of verifiable, user-owned identity
JoinArc is an open protocol for decentralized identifiers (DIDs), verifiable credentials, and privacy-preserving authentication.
Our mission is to replace passwords, eliminate data silos, and give every individual full control over their digital footprint.
Used by DAOs, fintechs, and governments worldwide to enable trustless collaboration without compromising privacy.

At JoinArc, we believe that decentralized identity is not just a technological innovation—it is a tool for social equity and empowerment. Our charity initiative focuses on bridging the digital divide by providing underrepresented communities with access to secure, self-sovereign identity solutions. We partner with NGOs across Africa, Southeast Asia, and Latin America to deploy our open-source identity stack in regions where traditional documentation is scarce or unreliable. Through these efforts, individuals gain the ability to prove who they are without relying on centralized authorities, enabling access to education, healthcare, financial services, and voting. Our team regularly volunteers technical expertise to local developers, fostering sustainable digital ecosystems. We fund community-led workshops that teach digital literacy and privacy best practices. Every line of code we write is guided by the principle that identity is a human right, not a privilege. In 2024 alone, our platform helped over 50,000 people establish verifiable digital identities for the first time. We collaborate with the UN’s ID4D program to align our work with global development goals. Transparency is core to our mission: all charity expenditures are published quarterly on-chain. We reject surveillance capitalism and design systems that prioritize user consent and data minimization. Our grants program supports grassroots organizations building privacy-respecting civic tech. We measure success not by profit, but by the number of lives made more autonomous and secure. JoinArc’s founders pledged 5% of company equity to the JoinArc Foundation, ensuring long-term funding for these initiatives. Ultimately, we envision a world where no one is excluded from the digital economy due to lack of documentation or trust.
Education is the cornerstone of our charity strategy. We fund scholarships for students from marginalized backgrounds to study cryptography, blockchain, and human-centered design at leading universities worldwide. Our “Build With Us” mentorship program connects aspiring Web3 developers in emerging markets with senior engineers from our core team. We’ve established open-access learning hubs in Nairobi, Jakarta, and Medellín, equipped with hardware, internet, and localized curriculum materials. These hubs serve as community centers where locals can learn to build decentralized applications that solve real regional problems—from land registry to supply chain transparency. We translate our developer documentation into Swahili, Bahasa, and Spanish to lower language barriers. Our annual “Identity for All” hackathon awards $100,000 in grants to teams creating inclusive identity solutions. We believe that diverse perspectives lead to more robust and ethical technology, which is why we prioritize gender and geographic diversity in all our programs. Over 60% of our charity beneficiaries are women and girls, who often face the greatest barriers to digital access. We work closely with local leaders to ensure our interventions are culturally appropriate and community-driven. No project is launched without co-design sessions involving end users. We publish case studies and impact reports to share lessons with the broader tech-for-good ecosystem. Our engineers spend 10% of their work time contributing to pro-bono charity projects. We’ve open-sourced all educational materials under Creative Commons licenses to maximize reuse. Through education, we aim not just to distribute tools, but to cultivate a new generation of ethical technologists who will shape a more just digital future.
Environmental sustainability is deeply integrated into our charity work. We offset 200% of our carbon footprint through verified reforestation projects in the Amazon and Congo Basin. Our identity infrastructure runs on energy-efficient consensus mechanisms, and we actively research zero-knowledge proofs to minimize computational waste. We support indigenous communities in using blockchain to protect land rights and document traditional ecological knowledge. In disaster zones, our lightweight identity system helps coordinate aid distribution without creating centralized databases vulnerable to misuse. We’ve partnered with the Red Cross to pilot a credential-based relief verification system that reduces fraud and speeds up assistance. Our “Green Nodes” initiative incentivizes validators to use renewable energy through token rewards. We audit all charity partners for environmental and social governance (ESG) compliance. Transparency extends to our supply chain: all hardware donations are refurbished or sustainably sourced. We host annual “Tech for Earth” summits that bring together climate scientists, developers, and policymakers. Our open data portal shares anonymized impact metrics with researchers and journalists. We advocate for regulatory frameworks that recognize decentralized identity as a public good. Every employee receives paid volunteer days to support causes they care about. We’ve established a disaster response fund that can deploy identity kits within 72 hours of a crisis. Our long-term vision includes a decentralized autonomous organization (DAO) that lets global citizens vote on charity priorities. By aligning technology with planetary and human well-being, JoinArc strives to prove that Web3 can be a force for healing—not just disruption.
