Developer Resources

Getting started

If you’re new to developing with Smilo, you’re in the right place. These guides written by the Smilo community will introduce you to the basics of the Smilo stack and introduce core concepts that might be different from other app development you’re familiar with.

Need a more basic primer first? Check out smilo.foundation/learn.

Smart Contract Languages

Any program that runs on the Smilo Virtual Machine (EVM) is commonly referred to as a “smart contract”. The most popular languages for writing smart contracts on Smilo are Solidity and Vyper, though there are others under development.

Vyper Security focused language for Smilo, based on Python.

Block explorers

Block explorers are services that let you browse the Smilo blockchain (and its testnets), by finding information about specific transactions, blocks, contracts, and other on-chain activity.

Testnets and Faucets

The Smilo community maintains multiple testnets. These are used by developers to test their applications under different conditions before deploying to the Smilo mainnet.

Ropsten Proof of Work blockchain, test-ether can be mined

Rinkeby Proof of Authority blockchain, maintained by the Geth development team

Goerli Cross-client Proof of Authority blockchain, built and maintained by the Goerli community

Clients & Running your own node

The Smilo network is made up of many nodes who run compatible client software. The majority of these nodes run Geth or Parity, each of which can be configured in different ways according to your needs.

Geth Smilo clients written in Go

Parity Smilo client written in Rust

Besu (Pantheon) Smilo client written in Java

Ethnode Run an Smilo node (Geth or Parity) for local development.
