Rootstock RPC Endpoint

Fast, flat-rate Rootstock RPC node provider — free tier, no KYC, HTTP & WebSocket.

Rootstock (RSK) is an EVM-compatible smart contract sidechain secured by the Bitcoin network through merged mining. Its native gas token, RBTC, is pegged 1:1 to BTC, bringing programmable smart contracts to Bitcoin holders.

About Rootstock

Rootstock launched its mainnet in January 2018 as one of the earliest Bitcoin sidechains. It uses merged mining, allowing Bitcoin miners to secure Rootstock with the same proof-of-work hashing, and produces blocks roughly every 30 seconds.

RBTC, the network's gas token, is backed 1:1 by BTC via the PowPeg two-way peg, and the supply mirrors Bitcoin's 21 million cap. The Rootstock Virtual Machine is compatible with the EVM, so Solidity contracts and Ethereum tooling can run on a Bitcoin-secured chain, supporting BTC-denominated DeFi.

Common Use Cases on Rootstock

• BTC-denominated DeFi (lending, DEXes)
• Stablecoins collateralized by RBTC
• Smart contracts secured by Bitcoin
• Tokenization on a Bitcoin-pegged chain
• Payments using RBTC

Rootstock Ecosystem

The ecosystem centers on BTCFi protocols such as Sovryn and Money on Chain, along with the RIF suite of developer infrastructure.
