About NuConstruct
NuConstruct builds a trusted order-flow execution layer for Ethereum and BNB Chain under the name TOOL: searchers submit transaction intents to nodes running inside Intel TDX trusted execution environments, which order and bundle them in encrypted memory and output only proofs, matching without revealing strategy and offering roughly one-second preconfirmations. It targets opacity in the MEV supply chain, where a handful of builders dominate and ordering power is concentrated and hard to audit.
Replacing reputation with hardware enclaves could make ordering verifiable while protecting searcher strategy from copying, but the security assumption rests on the chip vendor, and side-channel attacks plus the details of remote attestation are attack surfaces. As of October 2026 the project had no independently verifiable mainnet or product release, public information remains at the design and early testing stage, and no third-party audit has been published. For undelivered infrastructure, code and audits matter more than architecture diagrams.
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.
Throughout 2026 NuConstruct has kept its core product TOOL (Trustless Orderflow Operations Layer) running on the Hoodi testnet for roughly three months, slicing each 12-second Ethereum block into twelve 1-second subslots and using Intel TDX trusted execution environments to deliver verifiable transaction privacy and fair ordering. The team engaged Sigma Prime, authors of the Lighthouse consensus client, for a full codebase audit delivered in October 2026 as it prepares for mainnet launch.
NuConstruct's forward strategy centers on delivering a roughly 1-second block-time experience on Ethereum without protocol changes: validators opt in with a one-line MEV-Boost config change, positioning TOOL as an alternative to Flashbots' MEV-boost that splits the 12-second block into twelve 1-second subslots sharing partial state transitions. The roadmap adds default pre-trade privacy, finer-grained execution-ordering preferences for dApps, and atomic synchronous composability for rollups via early confirmations. The team targets quickly achieving over 50% pre-commitment on the validator side and aggregating over 80% of private order flow, channeling more than $300M in annual value flow to Ethereum validators.
