Cloud ex Machina Unveils AI Platform That Cuts Cloud Optimization from Hours to Minutes
Cubist, a security-focused Web3 infrastructure provider, announced the GA launch and production use of Cubist Confidential Cloud Functions (C2F), the first Web3 confidential compute platform powering production systems on Mainnet. C2F combines the privacy and speed of off-chain logic with the strong security guarantees of on-chain contracts to enable developers to run sensitive, compute-intensive, and cross-chain logic privately – creating a new foundation for private smart contracts and verifiable off-chain code.

As Web3 applications grow more complex, teams face a difficult tradeoff: do everything on-chain and accept high costs, limited performance, and total public visibility of data; or move logic off-chain and lose the guarantees of a smart contract. C2F eliminates this tradeoff by allowing developers to execute compute-heavy, sensitive, and custom code inside tamper-proof hardware at scale and across chains.
With C2F, developers write code with private data, external API calls, real-time market feeds, or sensitive business logic in familiar programming languages and deploy it through their existing CI/CD pipelines. Each execution is confined to a secure Trusted Execution Environment (TEE), ensuring code cannot be altered or influenced by the host system and is kept completely private.
C2F lets teams build:
Private smart contracts, which enforce contract-like rules off-chain and at low cost, while keeping signing logic (optionally) private.
Verifiable off-chain computation, which provides regulators, partners, or internal teams with verifiable evidence attesting to what code executed.
C2F is currently leveraged by leading Web3 teams for both private smart contracts and verifiable off-chain code, including for Squid’s newest version of its Cross-Chain Order Routing and Auction Layer (CORAL).
“We’re thrilled to partner with Cubist to supercharge Squid’s cross-chain liquidity network. By leveraging Cubist Confidential Cloud Functions, we’ve replaced on-chain smart contracts with private, off-chain logic, enabling sub-second swaps across EVM, non-EVM, and even non-smart contract chains like Bitcoin, all with higher reliability and better pricing,” said Fig, Co-Founder of Squid, a leading cross-chain liquidity provider. “We chose Cubist for their unmatched security and non-custodial standards, ensuring we advance next-gen crypto tech while upholding decentralization. I’m excited for our ongoing collaboration, delivering seamless solutions for institutions and retail users alike.”
Cubist Co-Founder and CTO Fraser Brown commented, “Web3 has opened up exciting possibilities across finance and beyond, yet developers are still constrained by tools that force them to choose between transparency and privacy, or between trust and performance. C2F is different: it’s live today, built specifically for the demands of production systems, and already enabling teams to build what simply wasn’t possible before – from enforcing smart-contract logic on chains that don’t support smart contracts, to applying custom, auditable signing rules to high-value transactions. We’re proud to be the first to deliver this solution in production and look forward to making off-chain logic enforcement a standard part of every Web3 tech stack.”
