Thru is a Layer-1 blockchain built on the RISC-V architecture, designed to provide a high-performance smart contract execution environment. Its core is ThruVM, a virtual machine based on the RISC-V instruction set, which allows developers to write smart contracts in mainstream languages like C, C++, and Rust without learning a new language. Thru offers gRPC and REST API interfaces, as well as SDKs and CLI tools, for querying on-chain state, submitting transactions, and deploying programs. Its design emphasizes performance, achieving efficient contract execution through the RISC-V instruction set and an optimized runtime.

About Thru
Unto Labs, the team behind Thru, completed a $14.4 million funding round led by Framework Ventures and Electric Capital, marking a key early milestone for the Layer 1 project.
The project publicly positioned ThruVM, built on the open RISC-V architecture, as a differentiator from EVM and Solana's BPF, aiming to lower the barrier for Web2 developers.
Thru set an ambitious performance target of 10x Solana's throughput, with the team's prior experience contributing to Solana's Firedancer client lending credibility to this goal.
The funding and technical direction established Thru's long-term strategic focus on bridging Web2 and Web3 use cases, including enterprise and traditional finance applications.
Thru (Layer 1) advanced steadily in H1 2026. Its RISC-V based ThruVM entered alphanet, with the core codebase partially open-sourced via Unto Labs' GitHub mirror. The team shipped the alphanet SDK, enabling developers to build and explore the chain. Notably, community members independently built Thruscan, the first third-party account explorer, and an AI-powered update tracker, demonstrating early ecosystem viability. Official focus remains on bootstrapping the ecosystem through native applications, leveraging ThruVM's ZK-friendly architecture and protocol-level Managed Fee Payer to attract mainstream developers. The roadmap prioritizes expanding the developer base, refining the SDK, and gradually decentralizing the network, with RISC-V positioned as the long-term differentiator against Solana's BPF.
