Not sure if Binance might enable on-platform mint and redeem in the future, and also have a mechanism to switch to the ceff-ethena account to allocate funds for minting and redeeming in emergency situations. Currently, minting and redeeming are done on-chain. When the reserve pool is empty, funds are automatically reallocated from ceff to the reserve pool. This process used to work fine, but now the volume on Binance is indeed too large. When the chain gets congested, two issues arise: first, the arbitrage players can't complete their cycles; second, Binance's hot wallet can't possibly afford to pay hundreds of dollars in gas fees for every transaction.
