Rootstock (RSK) is a Bitcoin-secured, EVM-compatible smart contract network whose native currency is RBTC (a 1:1 BTC‑pegged asset) used to pay gas. It powers Bitcoin DeFi (lending, DEXs, stablecoins), tokenization, and low-cost payments using BTC as collateral and settlement. Key performance: ~30s block time, ~100+ TPS theoretical throughput, penny-level fees (often <$0.05), and activity that typically ranges from hundreds to thousands of transactions per day depending on usage.
Rootstock is unique for being merge-mined with Bitcoin—historically secured by a majority of Bitcoin’s hash power—while remaining fully EVM-compatible for Solidity dApps and Ethereum tooling. Its trust-minimized PowPeg bridges BTC to RBTC so users can deploy native BTC into smart contracts, combining Bitcoin-grade security with low fees and fast settlement. For comparison, Rootstock targets ~30s blocks and penny-level fees, delivering higher throughput and lower costs than Ethereum mainnet while aligning security with Bitcoin miners.
Rootstock uses RBTC as the gas token for transaction fees. You can obtain RBTC by bridging from other chains or purchasing using thirdweb Bridge.
To bridge RBTC to Rootstock, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Rootstock as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Rootstock you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Rootstock to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send RBTC on Rootstock, ensure your wallet is connected to the Rootstock network, enter the recipient's address, specify the amount of RBTC to send, review the gas fee, and confirm the transaction in your wallet.
