# Libraries

Developers who want to construct DApps on the Bifrost Network can utilize any library that supports Ethereum. The following is a list of some of the supported libraries.

### Ether.js

The ethers.js library aims to be a complete and compact library for interacting with the Ethereum blockchain and its ecosystem. You can find more information in their [documentation](https://docs.ethers.io/).

### Web3.js/Web3.py

Web3.js has a longer history and more maintainers than Ether.js and it provides a single instantiated web3 object with methods for interacting with the blockchain.\
You can find more information in their [documentation](https://web3py.readthedocs.io/en/v5/).

### OpenZeppelin

[OpenZeppelin](https://openzeppelin.com/) is well known in the Ethereum developer community as their set of audited smart contracts and libraries has become a standard in the industry. For example, most of the tutorials that show developers how to deploy an ERC-20 token use OpenZeppelin contracts.\
You can find more information in their [documentation](https://docs.openzeppelin.com/openzeppelin/).

### Polkadot.js

For exceptional developers who require Substrate runtime, pallets, or client interactions for their DApp development, `polkadot.js` will be an optimal choice. You can find more information in their [documentation](https://polkadot.js.org/docs/api).
