In this guide, we'll walk you through the process of adding the Harmony One blockchain to your MetaMask wallet. Whether you're a beginner or an experienced user, this step-by-step tutorial will help you seamlessly integrate Harmony One into your MetaMask setup.
What Is Harmony One?
Harmony One is a blockchain network founded in 2018 by Stephen Tse, a seasoned software engineer with experience at top tech companies like Apple and Google. Harmony addresses the blockchain trilemma—balancing security, scalability, and decentralization—while also prioritizing privacy.
Key features of Harmony One:
- Sharding technology: Enables high throughput (2000+ TPS) by splitting the blockchain into smaller, parallel chains (shards).
- EVM compatibility: Supports Ethereum Virtual Machine (EVM), allowing seamless interaction with Ethereum-based dApps.
- Low fees: Transactions cost a fraction of those on Ethereum.
The network went live in June 2019 and introduced validator nodes in May 2020.
Harmony One Ecosystem
DApps on Harmony One
Harmony hosts over 40 decentralized applications (dApps), including:
- DeFi platforms: SushiSwap, Curve Finance, Aave.
- NFT marketplaces: LMA Art Gallery, daVinci.
- Native projects: Unique to Harmony’s ecosystem.
Thanks to EVM compatibility, developers can easily port Ethereum dApps to Harmony.
The ONE Token
The ONE token powers the Harmony blockchain, serving several purposes:
- Paying transaction fees.
- Staking (validators/delegators earn ~10% APY).
- Governance voting (validators only).
Token standards (compatible with Ethereum):
- HRC-20 (fungible tokens).
- HRC-721/HRC-1155 (NFTs).
Inflation is capped at 3% annually, offset by fee burns to maintain equilibrium.
How to Add Harmony One to MetaMask
Step-by-Step Guide
- Open MetaMask (download here if you don’t have it).
- Click the network dropdown (default: "Ethereum Mainnet").
- Select "Custom RPC".
Enter Harmony One’s network details:
Field Value Network Name Harmony One RPC URL https://api.harmony.oneChain ID 1666600000 Currency Symbol ONE Block Explorer https://explorer.harmony.one- Click Save.
Now, you can switch between networks via the MetaMask dropdown.
Bridging Assets to Harmony One
To transfer tokens from other EVM chains (e.g., BSC, Ethereum):
- Use Horizen Bridge or other cross-chain bridges.
- Ensure you’re sending to the correct HRC-20 address to avoid losing funds.
