Verifiable Data for Real-World Assets
Bring cryptographically provable off-chain data onchain: NAV reporting, balance verification, and institutional price feeds - with zero trust assumptions on the data source.
The Problem
Trust Gap in RWA Data
Protocols tokenizing real-world assets rely on off-chain data that is unverifiable onchain - custodian balances, NAV calculations, fund statements - creating audit risk and counterparty exposure.
Manipulation Surface
Traditional oracle feeds aggregate data through opaque pipelines. For RWAs, any single point of failure - API, aggregator, relay - can be a vector for manipulation or suppression.
Fragmented Data Sources
Custodians, fund administrators, and prime brokers expose data via HTTPS APIs - but there is no cryptographic binding between the source statement and the onchain value reported.
Regulatory Pressure on Proof
Evolving DeFi frameworks increasingly require verifiable proof of reserves and NAV for onchain RWA instruments. Attestations alone no longer suffice.
From Source to Chain.Verified at Every Step.
zkTLS proofs are generated during the TLS session with the data source, binding the HTTPS response to a zero-knowledge proof - without exposing private data. The proof is verified onchain alongside each data point, providing cryptographic guarantees that the reported value originates from the stated source and has not been altered in transit.

Built for Institutional DeFi
Tokenized money market funds, ETFs, and private credit vehicles require daily or intraday NAV delivery to onchain contracts. DIA zkTLS feeds pull NAV directly from fund administrator APIs, generating a cryptographic proof tied to the source TLS session.Smart contracts can enforce redemption and issuance at verified NAV - eliminating dependence on trusted intermediaries or manual attestations.
Custodian balance APIs (prime brokers, qualified custodians, bank APIs) are queried with a zkTLS session that proves the balance figure originated from the authenticated endpoint - not an intermediary relay.Collateral managers and lending protocols can enforce real-time collateral sufficiency checks against verifiable onchain proofs, reducing liquidation delays.
Physical commodities (gold, oil, agricultural), forex rates, and fixed income reference rates are sourced from institutional data providers via authenticated HTTPS APIs with zkTLS proof generation.Suitable for onchain derivatives, structured products, and tokenized commodity vaults that require tamper-proof spot and forward reference prices.

What Every zkTLS-Verified Feed Proves
Source Authenticity
The data originates from the stated HTTPS endpoint, not an intermediary relay or cache.
Data Integrity
The reported value has not been altered in transit between the source and the onchain contract.
Session Binding
The proof is cryptographically tied to the specific TLS session, preventing replay or substitution attacks.
Privacy Preservation
Zero-knowledge proofs verify data provenance without exposing private session details or API credentials.
