About RISCy

Bitcoin builders, your wait is over.

RISCy is a low-fee, Turing-complete UTXO network for Bitcoin builders, designed for instant finality and high-throughput applications.

Built on a Nexa-derived architecture capable of over 60,000 transactions per second, RISCy gives developers the programmable environment they've been waiting for: a UTXO-native network with a general-purpose RISC-V virtual machine. Instead of waiting for new Bitcoin opcodes that may never arrive, builders can create expressive smart contracts today in Rust, C, Zig, or anything that compiles to RISC-V.

RISCy is designed for Bitcoin-aligned applications that need more than Bitcoin Script can offer, while preserving the advantages of the UTXO model: parallel validation, native assets, low fees, instant finality, and proof-of-work security.

What makes the RISCy Network different

  • A general-purpose RISC-V VM -- write contracts in real languages, not a niche DSL.
  • UTXO-native design for parallel validation and predictable fees.
  • Instant finality and sub-cent fees for responsive, real-world apps.
  • Proof-of-work security, aligned with Bitcoin from day one.
