Smart contracts on Bitcoin.
Finally general-purpose.
A Turing-complete RISC-V sidechain on eCash — write real programs, not just scripts. Rust, C, or anything that compiles to RISC-V. Secured by Bitcoin miners via Drivechain.
Built different.
A sidechain designed for real programmability, not EVM compatibility theater.
RISC-V VM
Write contracts in Rust, C, Zig — any language that compiles to RISC-V. No proprietary bytecode.
UTXO Parallelism
Nexa-derived UTXO model enables parallel transaction validation. No global state bottleneck.
Drivechain Secured
BIP-300 hashrate escrow via eCash. Your sidechain inherits Bitcoin's security budget.
Blitz-Scalable
Nexa-class throughput architecture. Built for >100k TPS without compromising decentralization.
Near-Zero Fees
Sub-cent transaction costs. Microtransactions and high-frequency contracts are first-class.
Blind Merged Mining
BIP-301 lets Bitcoin miners secure Riscy with zero additional work. No separate token staking.
