Solana mainnet was shown to have capability to handle 100k transactions per second [1]. Granted, it was a synthetic benchmark of noops, but it shows the capability is there.
For reference, Visa claim 83k TPS [2] for their system. It also has the advantage of being vastly cheaper than tradfi payment networks at ca. $0.0005 per transaction [3] irrespective of transaction amount.
