Core platform

One platform.
Every rail.

Acquiring, payouts, routing and risk share one ledger — so a payment is a single API call, not five integrations.

Explore the platform →

Global acquiring

Accept cards, wallets and local methods in 180+ markets with a single integration and local currency settlement.

180+ markets1.4B cards

Instant settlement

Move funds the moment they clear. Daily, hourly or real-time payouts to any bank account.

T+0 payouts24/7 rails

Intelligent routing

Every transaction is scored and routed across 40+ acquirers to lift approval rates automatically.

Fraud defense

Adaptive models trained on 14B events block abuse without adding friction for good customers.

14B events0.02% fraud
For developers

Seven lines to
your first payment.

Typed SDKs, deterministic sandboxes and webhooks that never double-fire. The same API works for cards, wallets and bank debits.

  • Idempotent by default — retries are always safe
  • Sandbox that mirrors production behaviour
  • Webhook replay with signed payloads
