Acknowledging the tools and services that power our platform
Study Bitcoin and the HNDL protocol are built using a combination of trusted open-source tools, protocols, and services:
Powered by Rootstock
Our project is built on and actively contributing to theRootstocknetwork — the leading platform for DeFi on Bitcoin. By leveraging Rootstock's EVM-compatible infrastructure and secure PoW consensus, we enable Bitcoin-native applications and services that are fast, scalable, and trust-minimized.
Built with Solidity
Our smart contracts are written inSolidity, the most widely used programming language for Ethereum and EVM-compatible blockchains such as Rootstock. Solidity enables the development of secure, high-performance smart contracts that power decentralized applications.
We rely on Solidity's rich feature set and strong community support to build reliable and scalable blockchain solutions.
Smart Contract Foundation
The core contract architecture is based on libraries fromOpenZeppelin Contracts, a widely adopted set of secure and audited smart contract implementations for Ethereum and other blockchains. Specifically, this project uses the ERC721 Non-Fungible Token Standard for NFT functionality, distributed under the MIT License.
Account Abstraction
Wallet logic and account management are powered by theTokenbound Protocol, which enables NFT-bound accounts via ERC-6551. This allows each NFT to act as a fully autonomous smart contract wallet, capable of owning assets and executing transactions. Tokenbound is also open-source and available under the MIT License.
Blockchain Explorer & Transaction Data
On-chain transaction data used throughout the application is sourced via theBlockscout API. Blockscout provides open-source blockchain explorers for EVM-compatible networks, offering transparent and reliable access to blockchain data.
