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.
