Why use SPEI on Swaps

Swaps does not process payments itself — we route your SPEI transaction through licensed on-ramp providers and protocol routes (Paybis, Transak, Stripe Onramp, Bridge by Stripe, Onramper, Mercuryo, Partna, OKX, and others) and rank their live quotes by total receive amount in your local currency. The strongest provider route for SPEI depends on your country, the amount, and the coin you are buying, which is why every quote is re-evaluated in real time. The crypto goes directly to the wallet address you control; Swaps never custodies funds during the transaction.

What to expect

SPEI availability varies by provider and country. Some providers settle SPEI payments instantly, others may batch transfers depending on the rail. KYC requirements depend on the provider's compliance rules in your market — many corridors complete without verification at smaller amounts. Before you pay, Swaps applies a Tier-1 fiat-aware filter so SPEI routes that would be rejected by every available provider in your country never appear in the comparison. If a route is shown, it can complete; if it is hidden, the rail is not currently supported in your market.
