Builders,
Meet Bitcoin.
RISCy is a low-fee, Turing-complete UTXO network for Bitcoin builders. Stop waiting on opcodes that may never arrive -- write expressive smart contracts today in Rust, C, Zig, or anything that compiles to RISC-V.
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.
Learn more →UTXO Parallelism
Nexa-derived UTXO model enables parallel transaction validation. No global state bottleneck.
Learn more →Drivechain Secured
BIP-300 hashrate escrow via eCash. Your sidechain inherits Bitcoin's security budget.
Learn more →Blitz-Scalable
Nexa-derived throughput architecture. 60,000+ TPS today, scaling past 100,000 once Blitz hardware ships.
Learn more →Near-Zero Fees
Sub-cent transaction costs. Microtransactions and high-frequency contracts are first-class.
Learn more →Blind Merged Mining
BIP-301 lets Bitcoin miners secure RISCy with zero additional work. No separate token staking.
Learn more →On-chain Oracles
Native price and data feeds verified on-chain. Build DeFi, prediction markets, and more without trusting off-chain relayers.
Learn more →Instant Transaction Finality
Confirmations settle in seconds, not blocks. No waiting, no reorg anxiety -- what you see is final.
Learn more →Up to 70% Fee Payout to Builders
Ship apps and earn. Builders capture up to 70% of the fees their contracts generate, directly on-chain.
Learn more →Start building in minutes.
From zero to your first deployed contract -- no permission, no waiting on opcodes.
Download the node
Grab the prebuilt binary for your platform -- Linux, macOS, or Windows. No proprietary toolchain required.
Join the testnet
Start your node and connect to the RISCy testnet, then fund your wallet from the faucet with free test coins.
Write a contract
Build in Rust, C, or Zig -- anything that compiles to RISC-V -- using the same compilers you already know.
Deploy & iterate
Ship your contract to testnet, watch it settle with instant finality, and iterate for a fraction of a cent.
