Subsie

Payment infrastructure for recurring stablecoin billing. A JavaScript SDK and REST API create plans and hosted checkout sessions; customers connect MetaMask, WalletConnect or Coinbase Wallet and are auto-charged in USDC, USDT or DAI on Base. Includes smart dunning that retries failed charges and emails customers first, real-time MRR, ARR, churn, cohort and LTV analytics, webhooks for every payment event, and limited approvals — hard spending caps, cooldowns and one-click cancel with auto-revoke. Non-custodial, with no smart-contract team required. Currently in beta.

SaaS and subscription businesses that want to bill in stablecoins — crypto-native products, plus web2 companies whose customers would rather pay in USDC than with a card.

Crypto rails are built for one-off transfers. There is no native card-on-file, so recurring stablecoin revenue normally means writing and auditing your own smart contracts — and the usual workaround, unlimited token approvals, asks customers to hand a merchant open-ended access to their wallet.

Non-custodial by design, with limited approvals: hard spending caps, cooldown windows, and one-click cancel with auto-revoke, so a subscription grants less standing access than a credit card does. Settling on Base costs cents, which keeps micro-subscriptions profitable at price points card fees would erase.

Developer-led. A free Starter tier with one flat per-payment rate, a drop-in JS SDK and REST API, and hosted checkout let a merchant go live in a day without a smart-contract team; pricing then scales with volume. Exchange-native subscriptions are announced as coming next.
