Frequently asked questions about the Monad API
What is Monad Chain?
Monad Chain is a high-performance, Layer 1 blockchain that fully supports the Ethereum Virtual Machine (EVM). It uses parallel execution and the MonadBFT consensus to achieve 10,000 TPS, 500 ms block times, and 1-second finality—all while keeping node hardware requirements low for greater decentralization.
What is the Monad Chain API?
The Monad Chain API facilitates interaction with the Monad Chain network through a collection of JSON-RPC methods. It provides developers with tools to interact with the blockchain, enabling functionalities such as transactions, smart contract deployment, and data retrieval.
How can I get started using the Monad Chain API?
Explained in Monad Chain API Quickstart.
Is Monad Chain EVM compatible?
Yes. Monad Chain is 100% EVM-compatible at the bytecode level, enabling existing Ethereum smart contracts to run without modifications and work seamlessly with Ethereum’s tooling ecosystem.
What API does Monad Chain use?
Monad Chain uses the JSON-RPC API standard for blockchain interactions. This is the same standard used by Ethereum.
What is a Monad Chain API key?
When accessing the Monad Chain network via a node provider like Alchemy, developers use an API key to send transactions and retrieve data from the network.
For the best development experience, we recommend that you sign up for a free API key!
Which libraries support Monad Chain?
Common Ethereum libraries such as ethers.js, web3.js, and viem are supported, allowing for easy smart contract interaction and wallet management.
What programming languages work with Monad Chain?
It supports Solidity and Vyper for smart contracts, along with JavaScript and TypeScript for off-chain development, ensuring compatibility with projects that compile to EVM bytecode.
What does Monad Chain use for gas?
The native token, MONAD, is used for transaction fees. The network implements an EIP-1559-like fee mechanism that adjusts base fees dynamically while allowing users to tip for priority.
What methods does Alchemy support for the Monad Chain API?
You can find the list of all the methods Alchemy supports for the Monad Chain API on Monad Chain API Endpoints page.
