ZK-based credit draws, and automated repayment verification.
1. Onboard anchor & policy
Register anchor credentials and assign credit policy risk tiers on-chain via ParticipantPolicy.
2. Prove collateral health
Generate a zero-knowledge proof showing your private tokenized RWA reserves cover the USDC credit draw.
3. Draw & repay USDC
Execute the private USDC prefunding draw, run payout corridors, and repay to release locked collateral.
"We can verify anchor eligibility, enforce collateral requirements, and draw USDC prefunding without leaking our reserve sizes or corridor strength to the public."

and prefunding credit facilities fit together.
Nyx is a confidential short-term prefunding credit facility for Stellar anchors and payment institutions. It allows approved anchors to borrow 1-5 day USDC against private tokenized RWA reserves without exposing their balance sheets.
Because institutional compliance and credit limits depend on anchor risk profiles. The ParticipantPolicy registry binds each anchor wallet to a verified KYB state, risk tier, and credit limit before draws are authorized.
The proof verifies that the anchor's private RWA collateral covers the requested USDC draw after haircuts, and that the position does not exceed their risk-tier limits—all without revealing private balances.
Nyx supports tokenized treasuries (like cTBill) and tokenized gold (like cXAUm) as private collateral, with payouts and settlements denominated in confidential USDC (cUSDC).
Repayment of USDC automatically releases the collateral lock in the CollateralLockRegistry. If repayment is not made before the maximum tenor (1-5 days), the locked collateral commitment can be liquidated.
Stellar provides native USDC liquidity rails, high-speed settlement, and native support for tokenized RWA assets alongside compliance hooks for confidential tokens.
