Confidential RWA deal rooms for private credit. Investors submit encrypted bids, issuers repay onchain, and auditors verify with permissioned disclosure on Arbitrum Sepolia.

Description

Page: https://obscura-pi.vercel.app

Obscura Finance is a confidential RWA deal room for private credit on Arbitrum Sepolia. It brings sealed‑bid fundraising onchain without exposing sensitive positions, allocations, or repayment amounts. Investors submit encrypted commitments, issuers settle repayments transparently, and auditors access permissioned disclosure—all while amounts remain hidden at rest and in transit onchain.

At the core is a three‑layer architecture:

  1. Interface layer (Next.js + wagmi/viem) — role‑based dApp for Issuer, Investor, and Auditor flows;

  2. Encryption layer (iExec Nox Handle) — client‑side TEE encryption generating externalEuint256 + proof;

  3. On‑chain protocol (Arbitrum Sepolia) — ObscuraDealRoom.sol orchestrates deal state and confidential token transfers.

Technically, Obscura combines three standards:

  • ERC‑7984 Confidential Token for hidden balances and confidential transfers (euint256 handles).

  • ERC‑3643 Identity Registry for compliance gating (KYC‑verified investors only).

  • ERC‑7540 Async Vault for request/claim semantics (deposit & redeem events), adapted so assets=0 in events because the amount is confidential.

The protocol lifecycle is production‑grade:
Create Deal → Open Funding → Encrypted Bid → Funded → Encrypted Repay → Claim, with each step tracked onchain and each transaction linked in the UI. Issuers can grant auditor access per deal to verify encrypted bid data without disclosing it to the public. This replaces today’s private credit workflow—emails, spreadsheets, and ad‑hoc data rooms—with verifiable, compliant, and confidential onchain settlement.

In short, Obscura proves that private credit can be executed on public rails with institutional privacy, compliance gates, and cryptographic accountability—making RWA funding both scalable and verifiable.

Progress During Hackathon
