🧪 Subscription Flow: TDD Tests

1. Stripe (Fiat Payments)

• Stripe payment links for payments

• User Pays with Card

• After successful payment stripe send us subscription event via webhook

• After successful payment we make entry of subscription in DB

2. Radom (Crypto w/ USDC Payments)

• Generates a crypto payment link using Radom’s API with correct metadata (amount, plan, billing cycle).

• Asserts payment link redirects properly to Radom-hosted checkout.

• After users successful payment, randomly send us event via webhook

• After the successful subscription we then update DB

3. Okto Smart Wallet Integration

• Simulates Google OAuth login and Okto smart wallet generation.

• Asserts that the user gets a wallet address and session token securely.

• Submits an on-chain transaction (e.g., staking) via the Okto wallet.

• Asserts that the user did not sign with a private key or pay gas (the paymaster absorbed it).

• Asserts that the Okto smart wallet address is mapped to the user subscription record.

• Useful for syncing staking logic and AI agent access control.

4. Core Subscriptions & Agent Access Logic

• A valid subscription should allow the user to access the AI dashboard with relevant tier-based capabilities.

• Asserts tier correctly gates features (number of games, response time, etc.).

• Users with an active subscription can stake SKOR tokens.

• Asserts the staking contract only accepts calls from whitelisted (subscribed) wallets.

• Allows user to switch plans mid-cycle (pro-rated or effective from next billing cycle).

• Asserts user sees new plan info and pricing reflected in Stripe/Radom metadata.

🧰 Tools & Libraries Used

• Stripe SDK for fiat subscriptions

• Radom SDK + USDC for crypto subscriptions

• Okto SDK for smart wallet management and paymaster usage
