SE hinted in early September about adding support for more native stablecoins, likely including USDC due to Circle's backing, which is expected to boost TVL and expand use cases.
"In early September, SE hinted on X that it would be adding support for more stable coins. This presumably means that they'll be launching natively on SE. It seems they're all bridged from other chains for now. And coin bureau club members will know that circle is a big backer of say suggesting of course native USDC will be coming to say soon and this would further boost its TVL and expand its potential use cases."
