Paymentscan: KAST Settles Most Tracked Solana Card Volume
KAST accounts for most stablecoin card volume settled on Solana in Paymentscan's tracking. The Solana dashboard's spend-only view covers 9 of 13 programmes it tracks on that chain and uses onchain data. The figure measures settled card payments; money deposited into card accounts is a separate metric.
The concentration changes how a chain-level growth chart should be read. If one programme accounts for most volume, an increase in that programme's spending can move the chain total without implying equally broad growth across the other cards. Counting 13 tracked programmes does not mean the spend-only view has spending data for all 13.
The settlement chain is also a different question from the network a user can deposit from or the country where a card works. Card users should compare their actual funding options, costs and eligibility, rather than treating a network's aggregate volume as a card benefit.
When comparing this figure with KAST's cumulative top-ups, keep the measure and time window consistent. Use Spends and the same aggregation period on both views; a top-up total is not evidence of the same amount being spent at merchants.
