Might potentially be DBS bank based on my prompt to ChatGPT

"Based on the news reports and discussions from Fintech News Malaysia and industry chatter on LinkedIn, the undisclosed “very big” regional bank appears to be one of the top-tier institutions known for its digital innovation and active fintech investments. Among the top 10 ASEAN banks, DBS Bank stands out as the region’s largest and most aggressive in driving digital transformation.

Although it isn’t confirmed publicly which bank is behind the deal, DBS’s strong digital banking platform, extensive regional footprint, and past record of fintech partnerships make it a very likely candidate."
