Getting Started
A quick guide to getting started with developing on Harmony blockchain.
Harmony is a powerful blockchain that is EVM compatible with sharding and staking features. Developing on Harmony should feel very familiar for Ethereum developers, as Harmony is fully Ethereum compatible and inherits almost all the tools and libraries from Ethereum, like truffle, remix, web3js, etc.
The simplest way to interact with Harmony blockchain is via JSON RPCs.
To really explore the full potential of Harmony blockchain, creating a wallet is the next step.
Harmony uses bech32 address format with
one1
prefix, however Ethereum style hex address can also be used. For example: one1pdv9lrdwl0rg5vglh4xtyrv3wjk3wsqket7zxy
bech32 address is equivalent to 0x0B585F8DaEfBC68a311FbD4cB20d9174aD174016
hex address. Quick way to convert between formats is using explorer: https://explorer.harmony.one/#/address/one1pdv9lrdwl0rg5vglh4xtyrv3wjk3wsqket7zxy, at the top you will find "Address Format" ONE | ETH options.- Testnet faucets

We provide SDKs in several different languages. However most feature complete is our JavaScript SDK, which is the preferred language for DApp development.
Feel free to ping any POPS member for issues on the testnet network/explorer/faucet on harmony discord @harmony-pops or telegram P-OPS Team Validator
Faucet can also be refilled by anyone by sending fund back to the contract address shown on https://faucet.pops.one
- The most popular is our JavaScript SDK, which includes examples, documentation, and DApps developed in previous hackathons
- Other SDKs include: Golang CLI, Java SDK, Python SDK
- Note that, the Python SDK has only read-only features, meaning no transaction signing or smart contracts
