Data Layer

• MongoDB:

  • users, projects, keys

  • tx, analytics

  • webhooks

  • Solana tx cache

• Redis:

  • signatures

  • rate limits

  • sessions

The facilitator is stateless. It does NOT store:

• User accounts

• Payment history

• API keys

• Analytics

Your Responsibility: You should store in YOUR database:

• Payment records (payment_id, user_id, status)

• Transaction signatures for verification

• User access grants

• Business logic data

Example Storage Schema (Your DB):json

{
  "payment_id": "pay_abc123",
  "user_id": "usr_xyz",
  "amount": 0.01,
  "token": "SOL",
  "tx_signature": "2ZE7s...",
  "status": "completed",
  "created_at": "2024-01-01T00:00:00Z"
}
