Reef chain developer tools and resources.
You can connect to the developer UI for different networks:
types.json file for the block explorer UI can be found here.
To set the types.json go to Developer > Settings. example
The metadata syncing with the Polkadot browser extension will be offered to you automatically. Just click accept.
The block explorer for all Reef chain networks is available at
You can deploy and interact with smart contracts via EVM Playground UI: https://evm.reefscan.com
Solidity is a programming language for writing DeFi applications. The Solidity programs are compiled and uploaded to Reef chain, where they run in a completely decentralized fashion.
Here are some great resources for learning Solidity:
Compiling, deploying and managing Solidity smart contracts by hand can be a chore. For this reason we have developer frameworks for Python and JS/TypeScript.
Reef for JS/TypeScript devs
Reef for Python devs
Reef ecosystem for Python is coming soon.
Reef node commands
Here is a quick cheat-sheet with some of the most commonly used commands on the Reef node.
Compile the node
If you haven’t yet, compile the Reef node locally:
make build && cd target/release
Start the local development node
./reef-node \ --base-path /tmp/reefnode \ --chain dev \ --port 30333 \ --ws-port 9944 \ --rpc-port 9933 \ --rpc-methods Auto \ --rpc-cors all \ --rpc-external \ --ws-external \ --name MyNode
Reset the local chain
To prune (reset) the node run:
./target/release/reef-node purge-chain --chain dev
Generate a keypair
You can follow the accounts guide on how to use the CLI to make new keypairs.
