Stablecoins are gaining attention but still play a minor role in global online commerce, making up just 0.2% of transaction value, according to a report by Quinlan & Associates and IDA. Despite their potential for cost efficiency and transparency, stablecoin use remains mostly within the Web3 space due to regulatory uncertainties and a lack of non-USD options. With most stablecoins pegged to the USD, there's a call for more diversity, especially as 83% of countries don't use the USD as their main currency. IDA plans to launch a Hong Kong Dollar-pegged stablecoin to bridge local and global markets.
