DIA: Lanzamiento de DIA ZK

Today, we are excited to launch DIA ZK, the verifiable data assurance layer for DeFi, RWAs, and cross-chain applications.

Yield-bearing stablecoins, tokenized treasuries, and vaults built on offchain strategies now hold tens of billions in onchain value. The highest yields among them are earned offchain: basis trades on centralized exchanges, tokenized treasuries, private credit, CeFi lending. While the token lives onchain, the strategy that pays it does not.

That creates a problem for issuers. Holders, risk curators sizing allocations, and lending markets deciding whether to list a token cannot see the custody balances, exchange positions, or loan books behind the yield. They ask for proof, and an issuer-controlled dashboard or a monthly attestation is becoming less convincing as the basis for trust.

In June this year, a yield-bearing stablecoin lost its peg after the third-party service that verified its reserves ended its relationship. A lending market built around the token was left with roughly $18 million of affected collateral, and a separate vault with no direct exposure to the stablecoin was hit too because both relied on the same verifier.

DIA ZK addresses this. It proves that a reported value came from the stated source and was not altered on its way onchain. It proves the statement rather than the value: a condition such as reserves exceeding supply, without revealing the underlying figures. The proofs are posted and verified on DIA's oracle chain, rather than relying on a feed that a single verification provider can switch off.

Reserve disclosure requirements under MiCA already apply in the EU, and the US GENIUS Act will introduce federal reserve and disclosure requirements for qualifying stablecoin issuers. Continuously proving backing onchain, without forcing an issuer to reveal its underlying books, is the next capability the oracle layer has to provide.

If your protocol depends on stablecoin reserves, tokenized fund NAVs, or vault collateral held offchain, this is where to start.
