eCash Sidechain · Launching August 2026

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.

fork in ---d --h --m --s

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.
