Moonbeam repository has been migrated from purestake to the Moonbeam Foundation organization:
https://github.com/moonbeam-foundation/moonbeam
Github references/cloning as well as cargo build will keep working as expected. However, it is recommended to update those references once the migration is complete.
An Ethereum compatible Parachain built with Substrate.

# Join the public testnet
docker run --network="host" moonbeamfoundation/moonbeam:v0.36.0 --chain alphanet

Developers who are building dApps to run on moonbeam, may want a lightweight node to work with locally. You can quickly set up a single node without a relay chain backing it using the development service.
# Run a dev service node
docker run --network="host" moonbeamfoundation/moonbeam:v0.36.0 --dev
For more information, see our detailed instructions to run a development node
The above command will start the node in instant seal mode. It creates a block when a transaction arrives, similar to Ganache's auto-mine. You can also choose to author blocks at a regular interval, or control authoring manually through the RPC.
# Author a block every 6 seconds.
docker run --network="host" moonbeamfoundation/moonbeam:v0.36.0 --dev --sealing 6000
# Manually control the block authorship and finality
docker run --network="host" moonbeamfoundation/moonbeam:v0.36.0 --dev --sealing manual
Running Moonbeam in development mode will pre-fund several well-known addresses that (mostly) contain the letters "th" in their names to remind you that they are for ethereum-compatible usage. These addresses are derived from
Substrate's canonical mnemonic: bottom drive obey lake curtain smoke basket hold race lonely fit walk

To build Moonbeam, a proper Substrate development environment is required. If you're new to working with Substrate-based blockchains, consider starting with the Getting Started with a Moonbeam Development Node documentation.
If you need a refresher setting up your Substrate environment, see Substrate's Getting Started Guide.
Please note that cloning the master branch might result in an unstable build. If you want a stable version, check out the latest releases.
# Fetch the code
git clone https://github.com/moonbeam-foundation/moonbeam
cd moonbeam
# Build the node (The first build will be long (~30min))
cargo build --release
Moonbeam incorporates Rust unit tests and TypeScript integration tests, which are executed in CI and can also be run locally.
# Run the Rust unit tests
cargo test
Important
If you do not have pnpm, you can install with: npm install -g pnpm
cd test
pnpm i
pnpm moonwall test dev_moonbase
The Ethereum specification describes a numeric Chain Id. The Moonbeam mainnet will have a Chain Id of 1284, symbolizing the 1284 milliseconds it takes for a moonbeam to reach Earth.
Moonbeam nodes support a variety of public chains and testnets, each with their respective Chain Ids as follows:
Network Description | Chain ID | Target Relay Runtime |
---|---|---|
Local Parachain TestNet | 1280 | |
Local Development TestNet | 1281 | |
Reserved for other TestNets | 1282 - 1283 | |
Moonbeam | 1284 | Polkadot |
Moonriver | 1285 | Kusama |
Moonrock | 1286 | Rococo |
Moonbase Alpha TestNet | 1287 | Westend |
Reserved for other public networks | 1288 - 1289 |
Note that the runtimes can also be configured to target different relay networks.
The Moonbeam Runtime, built using FRAME, comprises pallets from Polkadot-SDK, Frontier, and the pallets/
directory.
From Polkadot-SDK:
- Utility: Allows users to use derivative accounts, and batch calls
- Balances: Tracks GLMR token balances
- Sudo: Allows a privileged account to make arbitrary runtime changes. This will be removed before launch.
- Timestamp: On-Chain notion of time
- Transaction Payment: Transaction payment (fee) management
- Randomness Collective Flip: A (mock) onchain randomness beacon, which will be replaced by parachain randomness by mainnet.
- ParachainUpgrade: A helper to perform runtime upgrades on parachains
- ParachainInfo: A place to store parachain-relevant constants like parachain id
From Frontier:
- EVM Chain Id: A place to store the chain id for each Moonbeam network
- EVM: Encapsulates execution logic for an Ethereum Virtual Machine
- Ethereum: Ethereum-style data encoding and access for the EVM.
The following pallets are stored in pallets/
. They are designed for Moonbeam's specific requirements:
- Author Inherent: Allows block authors to include their identity in a block via an inherent.
- Parachain Staking: Minimal staking pallet that selects collators by total amount at stake
When modifying the git repository for these dependencies, a tool called diener can be used to replace the git URL and branch for each reference in all Cargo.toml
files with a single command. This alleviates a lot of the repetitive modifications necessary when changing dependency versions.
