- SubQuery Network is a platform designed to simplify the process of querying blockchain data. It provides tools for developers to create, share, and monetize open APIs called SubQuery Projects. These projects can extract, transform, and serve blockchain data in a format that’s easy to consume for decentralized applications (dApps) and other blockchain-based projects.
- SubQuery Network simplifies blockchain data access and integration, enabling developers to build powerful applications with ease. By providing robust tooling, infrastructure, and monetization opportunities, SubQuery Network supports a diverse range of use cases across the blockchain ecosystem.

Code Details
- The Solidity code provided defines a set of smart contracts for an ERC20 token called `L2SQToken` that follows the Layer 2 (L2) standard for bridging tokens between Layer 1 (L1) and Layer 2 (L2) networks. The contracts also implement the ERC165 standard for interface detection.
- The `L2SQToken` contract is an example implementation of the L2 standard ERC20 token, named “SubQueryToken” with the symbol “SQT”. This token can be minted and burned by the L2 bridge, allowing seamless transfer of tokens between Layer 1 and Layer 2 networks.
- This set of contracts leverages the ERC20 and ERC165 standards to create a token that is compatible with Layer 2 solutions, enabling efficient and scalable token operations across different layers of the blockchain. The `L2SQToken` contract is a concrete example of how to implement a token that can interact with an L2 bridge for minting and burning operations.
