It can never be “non-custodial” in the same way on chain Bitcoin can be
Discussion
how do you define it? if I can compel a contract on L1 to give me back coins I am entitled from a mint, even when the offchain component of the mint is down or censoring, then I wouldn't consider that non-custodial. unilateral exit makes an offchain scaling solution non-custodial.
I mean. I guess never say never. I just wouldn’t compare current Ecash tech to on chain BTC in this regard
