Flare Confidential Compute Launches On Songbird, Bringing Private Institutional Data Onchain With Hex Trust’s USDX
Flare, a blockchain platform targeted on knowledge infrastructure, has launched Flare Confidential Compute (FCC) to Songbird, its canary community. The new system processes personal institutional knowledge and generates signed outputs that sensible contracts can confirm onchain, whereas the underlying info stays undisclosed. The first institutional deployment is a Proof of Reserves extension, with Hex Trust’s USDX turning into the primary stablecoin to undertake the know-how.
Smart contracts rely on knowledge they’ll independently confirm. Flare already handles public info by means of the Flare Time Series Oracle (FTSO) and the Flare Data Connector (FDC). However, institutional info corresponding to reserve balances, fund web asset values, collateral positions, credit score knowledge and compliance information usually can’t be made public. FCC addresses this hole by processing confidential inputs inside a registered Trusted Execution Environment (TEE) and returning a signed end result that contracts can verify earlier than performing on it. Only the aggregated conclusion is printed onchain, whereas the supply knowledge stays personal.
Proof of Reserves Comes to USDX
The preliminary FCC software is a Proof of Reserves extension constructed for belongings whose backing combines private and non-private components. Hex Trust is making use of it to USDX, its 1:1 USD-referencing stablecoin. Reserve info is provided from two sources, comprising a public reserves determine and a restricted money reserves quantity. The extension evaluates the mixed whole contained in the TEE in opposition to USDX provide throughout the ecosystem, then produces a signed final result indicating whether or not the stablecoin is backed 1:1 or above. The result’s printed with out revealing the underlying reserve figures.
USDX features as collateral within the FAssets system on Songbird, and its reference feed is transitioning to this reserve-based mannequin. Decentralized exchanges can use the identical final result as a pricing foundation for USDX, with feed metadata exhibiting at every replace whether or not protection meets the required threshold.
“Integrating Flare Confidential Compute enhances the belief layer for institutional adoption by enabling real-time, onchain verifiability of USDX reserves and thus manifesting its place as a trusted stablecoin within the Flare ecosystem,” Ben Usinger, Head of Stablecoins at Hex Trust in a written assertion.
Verifiable Execution Behind the Scenes
FCC allows contracts to substantiate not solely the end result but additionally the situations during which it was produced. Songbird knowledge suppliers relay and signal each instruction below Flare’s signing coverage, and the TEE executes an instruction solely as soon as it carries a weighted majority of supplier signatures. This supplier set is identical one which operates the FTSO and FDC. Each accredited FCC code model is represented by the hash of a reproducible container picture accredited onchain, so machines operating unapproved software program can not register, and upgrades change into onchain occasions.
When becoming a member of an extension, a TEE presents {hardware} attestation confirming it runs an accredited code model. The attestation is verified by means of the FDC and recorded onchain. The machine’s signing key’s created contained in the enclave at boot and by no means leaves it. The TEE indicators its output with this registered id, and a verifier contract generally known as the TEE registry validates the signature earlier than another contract can retailer or use the end result. For Proof of Reserves, FCC combines public reserve elements, personal reserve information and token provide in a single calculation, then applies an outlined protection rule starting from a single threshold to a multi-condition coverage.
FCC rounds out Flare’s knowledge infrastructure by extending it to info that can not be printed straight onchain, sitting alongside the FTSO for public market knowledge and the FDC for cross-chain and Web2 verification, all below one network-level supplier set and signing coverage. This establishes a shared framework for functions requiring verified conclusions from personal knowledge, together with lending markets that mix public costs with personal protection info, tokenized funds producing verifiable NAVs from undisclosed holdings, and credit score or compliance use instances the place information should stay confidential.
FCC is presently stay on Songbird following the acceptance of STP.13 in July 2026, with a separate deployment on Flare to comply with. The preliminary launch runs on TEE machines utilizing Google Cloud confidential computing, operated by the Flare Foundation, and the structure is meant to increase towards a wider set of operators and {hardware} distributors. The extension framework will open to builders later throughout the bootstrap interval, with documentation obtainable by means of the Flare Dev Hub.
