There are multiple ways.
Stablesats uses a derivatives strategy, so there is no "issuer" per say.
Overcollateralized stablecoins are backed by collateralized debt positions owned by users.
Algorithmic stablecoins are a synthetic asset backed by a set of incentives to keep the peg.
Thanks but I thought Terra/LUNA showed perils of algorithmic pegging? Someone figures out how to exploit something unforeseen and it's over.

Yes, but there are non-algorithmic overcollateralized stablecoins or semi-collateralized semi-algorithmic (like frax).
