Hey Waynee, thanks for the feedback.
eBTC won’t be “real” BTC but rather a synthetic asset (soft) pegged to the price of BTC. It will be the only of its kind to offer a capital efficient and censorship resistant way of using BTC in DeFi. It won’t be backed directly by BTC but rather by LSDs so yes, even when BTC reaches the 21M supply, eBTC will continue to be mintable. This shouldn’t be a problem since, even if pegged, they serve different markets and have different utilities, they are different assets.
