USDR (Rain Dollar)
Zealynx is reviewing USDR (Rain Dollar) as an external contractor engagement for Composable Security, in a three-week review. USDR is a multi-collateral, over-collateralized stablecoin on Arbitrum One adapted from MakerDAO's Multi-Collateral Dai, backed by a basket of USDT, USDC and RAIN and built around one rule enforced at every block: the protocol's maximum possible loss can never exceed its stable reserves. The scope covers the core ledger and collateral adapter, the oracle security module and price converter, the peg stability module, reserve accounting and the solvency engine, the liquidation stack with its circuit breaker, and the timelocked governor. The report will be published when the engagement closes.
