NuConstruct is a crypto infrastructure company whose core product is TOOL (Trustless Orderflow Operations Layer). It leverages Intel TDX Trusted Execution Environment (TEE) technology to split each 12-second Ethereum mainnet block into 1-second mini-rounds, enabling fast, private, and front-running-resistant orderflow execution through sealed-bid auctions. This solution does not rely on Rollups or modify Ethereum's underlying protocol, yet significantly improves transaction confirmation speed and protects user privacy. NuConstruct supports Ethereum and BNB Chain, serving users, traders, dApps, and enterprises with efficient on-chain transaction processing. The project completed a $6 million seed round led by Cyber Fund.

About NuConstruct
NuConstruct is a developer of on-chain execution tools. Its core product, TOOL (Trustless Orderflow Operations Layer), leverages Intel TDX TEE to build a trusted execution environment. The project attempts to divide Ethereum's current ~12-second block time into twelve 1-second micro-rounds, aiming to reduce transaction confirmation time to roughly one second without requiring Rollups or modifying the Ethereum mainnet protocol. The solution is designed to achieve fair transaction ordering and end-to-end privacy through hardware-grade trusted execution, addressing issues such as censorship and front-running in existing MEV mechanisms, and potentially replacing Flashbots MEV-boost to improve the on-chain trading experience. The protocol does not rely on staking or slashing, but rather on economic incentives and a decentralized network.
During the period from March 5, 2026, to September 5, 2026, no reliable public progress updates were found, so its specific development status during this timeframe cannot be confirmed. No major negative reports (excluding informal user complaints) were identified within the past two years.
Founded in 2022, NuConstruct (nuconstruct.xyz) has focused on on-chain execution tooling, with a team active in Ethereum MEV since 2020.
On June 11, 2025, the project closed a $6 million seed round led by Cyber Fund, with Maven11, DCG, Greenfield, and Eden Block participating. Around the same time, its flagship product TOOL (Trustless Orderflow Operations Layer) was unveiled: using Intel TDX TEE and block "pre-sharding," it aims to reduce Ethereum L1 transaction confirmation to 1 second without rollups or protocol changes, while adding default pre-trade privacy and more open block auctions. In June 2025, TOOL was set to launch on the Hoodi testnet, supported by the Ethereum Foundation, Coinbase, Figment, Chorus One, and Obol Network, with a mainnet MVP to follow. These milestones mark the project's shift from research to deployment.
In April 2026, NuConstruct presented its TOOL sub-slot execution design at the Blockspace Forum workshop. Each 12-second Ethereum slot is divided into sub-slots of roughly 200ms–1s; after each sub-slot, partial state transitions are shared, enabling early execution confirmations. Proposers opt in via a one-line MEV-Boost config change, requiring no protocol fork. Research shared at the workshop indicates that shorter sub-slots do not necessarily raise per-trade profit, but significantly increase trading volume and total fees by reducing forecast variance. A proposer “blinding” mechanism prevents cherry-picking between sub-slot blocks and PBS blocks. Official roadmap priorities: complete testnet phase in 2026, then mainnet deployment pending validation. The hardest open problem is how sub-slots interact with the existing PBS pipeline; four scenarios were discussed without consensus, and the contentious/non-contentious transaction split is seen as a key complementary design direction.
