The Problem
E-commerce merchants want to accept crypto but face a dilemma: custodial gateways introduce counterparty risk and fund lockup, while self-hosted solutions require significant technical expertise and maintenance. Existing options are either too risky, too complex, or charge excessive fees.
Potential Solution
A SaaS payment gateway that provides plug-and-play integration for major e-commerce platforms, generating payment addresses that deposit directly into merchants' self-custodied wallets. The service handles payment detection, confirmation tracking, webhook notifications, and accounting reconciliation without ever touching the funds.
Why Now?
Crypto payment adoption is accelerating, merchants are seeking alternatives to 3% credit card fees, and AI-assisted development has dramatically reduced the cost and time to build robust fintech infrastructure.
