Mainnet Checklist

Before switching your app to Mainnet, verify every item in this checklist. There are no approval requirements from Pollar — this is a technical checklist you verify independently.

---

Dashboard configuration

• Created a separate Mainnet app in the Dashboard (do not reuse your Testnet app)

• Generated pub_mainnet_ and sec_mainnet_ keys

• Added your production domain(s) in Dashboard → Configuration → Domains

• Funding mode configured correctly for your use case

• At least one asset configured in Tokens / Trustlines

• Branding & UI configured with your production logo and colors

---

App Wallets

• Funding wallet active on Stellar Mainnet with sufficient XLM

  • Recommended minimum: 50 XLM to start

  • Calculate based on expected activations: activations × (1 + assets × 0.5) XLM

• Gas wallet active and funded

  • Recommended minimum: 10 XLM

• Distribution wallet funded (if using fund() on mainnet)

• Low-balance alerts configured in Dashboard → Configuration → Alerts

  • At minimum: email alert for funding wallet below 20 XLM

---

Environment variables

• pub_mainnet_ key set in your production environment

• sec_mainnet_ key set in your backend production environment

• No testnet keys present in production environment variables

• Keys not committed to version control

---

Backend (Deferred mode only)

• POST /activate endpoint deployed to production

• Endpoint uses sec_mainnet_ secret key

• Endpoint validates input before calling Pollar

• 409 Conflict response handled as success (wallet already active)

• 402 Payment Required triggers an alert — your funding wallet needs a top-up

---

SDK integration

• PollarProvider uses production publishable key

• No hardcoded testnet addresses or amounts

• Error handling implemented for sendPayment() failures

• Wallet status: 'pending' handled in the UI (Deferred / Manual mode)

• fund() on mainnet explicitly enabled in Dashboard if used

---

Testing

• Full onboarding flow tested end-to-end on Mainnet with a real user account

• At least one real USDC payment sent and confirmed

• Transaction appears in Dashboard → Observability → Transactions

• Wallet visible on Stellar Expert

• Webhook events received correctly (if configured)

---

Observability

• Dashboard → Observability → Logs monitored after first real users

• Error alerting set up (Sentry, Datadog, or similar) for your backend

• Sponsorship wallet balances checked after first day of real usage
