Language
TypeScript
The whole platform — website, app and server — is written in strictly typed TypeScript.
Technology
How LamportPay is built
The tools and services behind the platform. For payout and liquidity partners, see Partners & integrations.
Application
Web framework
React & TanStack Start
Server-rendered React pages with type-safe routing and server functions.
Design system
Tailwind CSS
One shared design system for the website, the app and the admin console.
Data & infrastructure
Database
SQL (Postgres)
Our database is designed and written in SQL by our own team. Payment records, accounts and the admin audit log live in Postgres with row-level security, and the audit log is append-only.
Server runtime
Node.js
Server-side logic — payment orchestration, webhooks, reconciliation and admin tooling — runs on Node.js.
Hosting
Cloud hosting
The website and app are hosted on managed cloud infrastructure today, with a planned move to AWS as we scale.
Future infrastructure
AWS
Our roadmap includes migrating the platform's infrastructure to AWS.
Transactional email
Resend
Payment receipts and account emails will be sent through Resend.
How we build
Core development
In-house engineering team
LamportPay's core platform — the payment engine, database design, security controls and integrations — is designed and built from scratch by our own developers.
Productivity & automation
AI-assisted tooling
Our team uses AI tools such as ChatGPT, Claude and Lovable to speed up coding, testing, automation and marketing. They assist our developers — the architecture, financial logic and security decisions are made and reviewed by the team.
Security & quality
Partner events
Svix-signed webhooks
Every payout status update from Stables is signature-checked before it is processed.
Automated checks
GitHub Actions CI
Type checks, linting, 500+ tests, secret scans and dependency audits on every change.
Security & data handling
Customer funds are never held by LamportPay — every payment moves from the customer's own wallet to a single-use deposit address issued for that transfer. Accounts, payment records and the admin audit log live in Postgres with row-level security, and the audit log cannot be edited or deleted.
For the full list of what is live, simulated, in progress or planned, see Partners & integrations, the compliance page, and the cookie policy. Found a security issue? Write to us at hello@lamportpay.com.
