Stablecoin Payment Infrastructure

Coinsub is a stablecoin payment infrastructure platform enabling merchants, SaaS platforms, e-commerce businesses, and payment service providers to accept, send, and manage stablecoin payments through a single, compliance-ready stack.

Product Overview

Founded in 2023, Coinsub provides the full money movement layer for stablecoin commerce — covering payment acceptance, outbound payouts, wallet and balance management, and currency conversion. The platform supports USDC, USDT, and other major stablecoins, and is designed for fast integration (live in 2–3 days) with a developer-friendly API and webhooks stack. Coinsub is FinCEN MSB-registered in the US, FINTRAC-registered in Canada, and is pursuing ISO 27001 and SOC2 certifications.

Key Features

• Payment Acceptance: Branded checkout with pay links, subscription billing workflows, and invoice tooling. Real-time payment status, transaction history, sandbox testing, and export tools included.
• Payouts: API-driven batch disbursements to customers, partners, and contractors via integrated partner network, with optional currency conversion at point of disbursement.
• Wallet & Balance Management: Centralized stablecoin balance visibility and controls across USDC, USDT, and other major stablecoins, integrated across acceptance and payout workflows.
• Currency Conversion: Seamless conversion between fiat and stablecoins, and cross-stablecoin swaps (e.g., USDC to USDT).
• White-Label Platform: PSPs, acquirers, and commerce platforms can deploy the full Coinsub stack under their own brand with plug-and-play checkout components and full API access.

Use Cases

Coinsub targets SaaS businesses, e-commerce platforms, marketplaces, and payment processors seeking stablecoin rails without rebuilding existing checkout infrastructure. Key benefits include elimination of chargebacks (irreversible on-chain transactions), reduced payment declines, and access to global customers in regions where traditional card acceptance is limited or unreliable.
