KBank turns Thailand-Singapore QR travel spend into a named settlement stack

KBank's Q Wallet now lets Thai travellers pay Singapore merchants via Grab QR, with Q-money on Quarix interoperating with StraitsX's XSGD under the Bank of Thailand sandbox.

The launch proves a live, Thailand-origin QR travel-spend route into Singapore merchants with named settlement plumbing: Q Wallet, Grab QR, Q-money, Quarix, StraitsX XSGD, and Purpose Bound Money controls.

It does not yet prove broad merchant scale, material corridor volume, or a fully two-way production corridor beyond sandbox conditions.

KBank's 8 April launch makes the traveller rail, merchant rail, and settlement rail explicit: Thai users pay Singapore Grab QR merchants from Q Wallet, with Q-money on Quarix interoperating with StraitsX's XSGD inside the Bank of Thailand sandbox. The record still stops short of broad corridor scale.
