PromptPay settles baht in seconds from any Thai banking app to a registered ID or mobile number.
Cards through your own processor account and SWIFT for cross-border transfers, available in Thailand like everywhere.
Baht checkouts can offer PromptPay to a published PromptPay ID; crypto rails cover buyers who settle on-chain.
The checkout offers PromptPay for buyers paying from THB accounts, cards through your processor account, and the crypto assets for wallet holders. One surface, every path your market uses.
Prices stay in Thai Baht (THB); the checkout derives the crypto amounts live at payment time and the ledger reconciles against the denomination.
Local rails settle in their own window with a reference per order, and crypto legs settle on-chain non-custodial.
Every payment lands in the queue with its reference and rail detail; the export feeds your ledger and the day closes itself.
The everywhere rails deserve their own sentence in Thailand: card processing through your own account serves every buyer with plastic at your negotiated rate, and SWIFT ties THB accounts into the global banking system for the transfers the local rails do not carry. The crypto legs compress the same geography differently: settlement is identical worldwide, so a THB corridor that once routed through correspondents can clear as a token transfer. Which path wins is a per-payment fact: local rails on domestic cost and speed, cards on reach, crypto on borderless finality, and a composed checkout simply offers all three.
Serving Thailand well is mostly sequencing: put the local rail first for domestic buyers where cost and speed win, keep cards on for the plastic habit, and leave the crypto legs enabled for the wallet holders and cross-border receipts that would otherwise pay correspondent fees. The reference discipline does the bookkeeping: each order carries its own, so whichever rail a buyer picks, the payment matches itself and the day's export groups cleanly by rail for the ledger.
The crypto side of checkout does not localize: 56 assets on 35 networks settle identically in Thailand as everywhere else, non-custodial to your wallet, final on confirmation, around the clock. That sameness is the strategic property. Whatever the local rail picture looks like today, the crypto legs give Thailand merchants a payment path with no local dependency at all: no processor approval, no banking hours, no currency conversion at the rail. Buyers pay from any wallet on any supported chain, the invoice keeps its denomination, and settlement lands wherever you point it.
