ERC-4626 compliant vault with subscription logic

⚡

Principal preservation — users only spend yield

⚖

Configurable yield split (provider vs user surplus)

ERC-4626 vault where deposited yield pays for subscriptions while the principal remains intact. Users deposit once, yield streams to the service provider, and the user keeps their deposit. Inspired by Superfluid streaming but with vault-native yield.
