🏛️ UIP-16:Usual Zero Rate Module (UZR): Adding U0R as USD0 Collateral

Governance at Usual moves in deliberate steps. UIP-16 follows this approach.

The proposal introduces Usual Zero Rate Token (U0R) as eligible collateral for USD0 on Ethereum mainnet. This is a strictly technical, preparatory change — not a new product and not the broader infrastructure transition.

Following UIP-11 (USUAL inflation reduction), governance set the USL rate to 0% and stopped USUAL emissions for bUSD0 used as USL collateral. UIP-16 adds U0R as new USD0 collateral via a dedicated module: UZR (Usual Zero Rate Module), explicitly designed with a 0% rate.

UZR will coexist with the current USL on Euler: nothing is replaced or imposed. Users can stay or migrate.

UIP-16 enables essential real-world tests (security, integrations, on-chain behavior, accounting, flows) before a separate proposal details the full target architecture. It does not change USD0’s risk framework or monetary policy — it simply reduces risk by validating assumptions on-chain.

A detailed technical description of the future infrastructure will be submitted to governance soon.
