Builds a suite of Stellar payment adapters that let developers seamlessly enable crypto payments in modern web tools and marketplaces.
Stellar Tools is a suite of Stellar-native payment adapters designed to integrate directly into modern web frameworks and SaaS platforms. Our goal is to simplify developer workflows, unlock real-world crypto payments, and drive Stellar adoption globally—without requiring blockchain expertise.
Phase 1 — Core Adapters (in development)
BetterAuth Adapter – Adds Stellar-based payments to authentication flows, enabling user-linked billing and secure, on-chain settlement.
AI SDK – Agentic Payments – Allows autonomous agents to trigger Stellar payments per action, enabling real-time, AI-driven billing without manual steps.
AI SDK – Metered Billing – Supports per-use billing models for AI apps using Stellar, ideal for usage-based monetization and global settlement.
Convex Adapter – Enables Stellar-backed backend usage tracking and pay-per-action microtransactions, improving real-time settlement efficiency.
Clerk Adapter – Integrates Stellar billing with authentication, allowing seamless per-user payments and monetized SaaS workflows.
MedusaJS Adapter – Provides Stellar checkout integration for headless e-commerce, unlocking crypto-native payment flows for thousands of merchants.
Trigger.dev Adapter – Powers workflow and recurring payments with Stellar, simplifying subscription billing, retries, and automation.
PayloadCMS Adapter – Enables SaaS-style recurring or usage-based payments on CMS platforms using Stellar USDC.
UploadThing Adapter – Implements Stellar-based pay-per-upload logic, ideal for monetizing file storage via microtransactions.
Shopify App Adapter – Full Stellar integration into Shopify’s checkout experience, enabling 5.5M+ stores to accept crypto payments.
WooCommerce / WordPress Plugin – Stellar-powered gateway for the WordPress ecosystem, unlocking crypto billing for millions of merchants and plugin developers.
Ecosystem Impact
Expands Stellar adoption across high-usage dev ecosystems (Next.js, Vercel, Clerk, Medusa, etc.) and real-world commerce platforms (Shopify, WordPress).
Reduces friction for developers and merchants integrating crypto payments—no need to rebuild workflows or learn blockchain.
Enables real-world crypto usage via seamless billing flows, increasing network activity, transaction volume, and cross-border settlement on Stellar.
Maybe in the future, but not in this submission
$53.5K
Developer & Merchant Adoption
→ Stellar adapters adopted by 500+ developers or merchants within the first 6 months.
Transaction Volume
→ 10,000+ Stellar transactions processed through the adapters during the same period.
Ecosystem Integration
→ Live integrations with major platforms such as Shopify, WordPress, MedusaJS, Clerk, and Trigger.dev.
SDK Engagement
→ Track npm downloads, GitHub stars, and repository forks as key indicators of developer usage and community interest.
Impact on the Stellar Ecosystem
Expand Financial Access
→ Allow developers and merchants worldwide to accept Stellar-based payments, reducing reliance on traditional payment processors and expanding crypto usability.
Increase Network Activity
→ Drive real-world transaction volume, asset usage, and ecosystem engagement on the Stellar network.
Lower Integration Friction
→ Enable developers to integrate Stellar without blockchain expertise, using plug-and-play adapters across the tools they already use.
Ecosystem Growth
→ Position Stellar as a native part of modern SaaS and e-commerce infrastructure, strengthening its role in mainstream developer workflows.
Our GTM plan focuses on meeting developers where they already build, using a combination of open-source exposure, direct platform integrations, and community-driven outreach.
1. Platform PRs & Documentation Contributions
Submit pull requests (PRs) to platforms like Shopify, WordPress, MedusaJS, Clerk, and Trigger.dev to include our Stellar adapters in official docs and tutorials
Model after BetterAuth’s successful integration approach
Include code samples, quickstart guides, and usage demos to ensure developers can plug in instantly
2. Open Source Distribution & NPM Visibility
Publish all adapters as open-source NPM packages, with clean READMEs, usage examples, and “Getting Started” guides
Use GitHub trending and npm download metrics as credibility signals to drive early traction and show developer trust
3. Community & Developer Engagement
Share Stellar integrations in developer communities:
→ Discord servers, Subreddits, and dev forums for Shopify, WordPress, and SaaS tools
Create bite-sized demo videos, step-by-step tutorials, and DevRel content to reduce onboarding friction
4. Direct Outreach to Early Adopters
Identify 50–100 high-potential early adopters (Shopify merchants, MedusaJS users, SaaS teams)
Offer personalized onboarding, integration help, and early support in exchange for feedback and testimonials
5. Showcase Results & Metrics
Publish dashboards with real-time adoption metrics, testnet transaction volumes, and usage data
Use this transparency to build trust, validate product-market fit, and attract additional merchants and developers
6. Leverage the Stellar Ecosystem
Promote adapters via Stellar developer channels: forums, Discord, newsletters
Include clear calls to action linking to npm packages, GitHub repos, and live demos
While the project is pre-launch, the demand for plug-and-play payment adapters is already validated at massive scale across the modern developer ecosystem. Our work doesn’t try to invent new behaviors, it brings Stellar and USDC directly into the workflows developers already use, where Stripe is currently the default.
We’re integrating Stellar into platforms that are already proven:
Better Auth’s Stripe adapter has 20,000+ weekly installs on npm, demonstrating real usage of authentication-layer payments
→ npm link
MedusaJS’s Stripe plugin sees 271,000+ weekly installs, showing that e-commerce developers expect drop-in payment support
→ integration link
WooCommerce’s Stripe gateway powers 900,000+ active stores on WordPress, real merchants, processing real payments every day
→ plugin link
Shopify, used by 4.8M+ online stores, defaults to Stripe, reinforcing the dominance and importance of the payment adapter model
→ market data
Convex, UploadThing, and Trigger.dev all provide official billing guides using Stripe, proving that usage-based billing and pay-per-action models are now standard in modern SaaS and AI toolchains
→ example: Convex + Stripe
Stripe has become the default because it’s easy to integrate and invisible once deployed. We’re offering Stellar the same opportunity: seamless, low-friction USDC rails that developers can enable with one line of config, without changing their stack or learning blockchain.
By integrating Stellar into these proven workflows, we’re not chasing adoption, we’re meeting developers where they already are.
