Harmony

ONE

Harmony is a sharded Layer 1 that runs Ethereum-style smart contracts across several shards, with the native token ONE used for fees and staking.

Overview

Harmony at a glance.

Harmony launched its mainnet in 2019 as a sharded proof-of-stake network designed to run Ethereum applications at lower cost. It splits work across multiple shards and uses a delegation-based staking model to secure each one. Here is how it works and what it is used for, not the price.

How it works

How Harmony works.

Harmony secures its network with Effective Proof of Stake, a staking design built for a sharded chain. Token holders stake ONE or delegate it to validators, who are spread across shards so that each shard carries a comparable amount of stake. EPoS adjusts rewards so that very large validators are pushed to run additional nodes rather than concentrate stake, and double-sign behavior can be slashed.

Consensus: Effective Proof of Stake (EPoS)

Harmony secures its network with Effective Proof of Stake, a staking design built for a sharded chain. Token holders stake ONE or delegate it to validators, who are spread across shards so that each shard carries a comparable amount of stake. EPoS adjusts rewards so that very large validators are pushed to run additional nodes rather than concentrate stake, and double-sign behavior can be slashed.

Sharding

Harmony divides state, network, and transaction processing across multiple shards so they can produce blocks in parallel rather than one global chain handling everything.

EVM compatibility

The network runs Ethereum-style smart contracts, so contracts and tooling written for the EVM can be deployed on Harmony with familiar workflows.

ONE token

ONE is the native token. It pays transaction fees and is staked or delegated to validators to help secure the shards and earn staking rewards.

Epochs

Time on Harmony is grouped into epochs of a fixed number of blocks. Validator sets and shard assignments are updated at epoch boundaries.

Ecosystem & usage

What Harmony is used for.

Harmony hosts EVM-based decentralized applications, token contracts, and cross-chain tools built on its sharded design.

DefiLlama

Smart contract apps

Developers deploy EVM contracts for decentralized finance, tokens, and other on-chain applications on Harmony.

Staking and delegation

Holders stake ONE directly or delegate to validators to take part in securing shards and earning rewards.

Low-cost transfers

ONE is used to send value and interact with contracts at low fees compared with mainnet Ethereum.

FAQ

Common questions.

What is Harmony?
Harmony is a Layer 1 blockchain that launched its mainnet in 2019. It uses sharding and Effective Proof of Stake to run Ethereum-compatible smart contracts across multiple shards.
What is the ONE token used for?
ONE is the native token of Harmony. It pays transaction fees and is staked or delegated to validators that secure the network.
Is Harmony compatible with Ethereum tools?
Yes. Harmony is EVM-compatible, so smart contracts and tooling designed for the Ethereum Virtual Machine can be used on it.
How does staking work on Harmony?
Holders can stake ONE or delegate it to a validator. Under Effective Proof of Stake, stake is distributed across shards and validators can earn rewards or be slashed for double-signing.
Can I hold ONE in Zypto App?
Not yet. ONE isn't in Zypto App at the moment. You can hold it in any self-custodial wallet, and you can ask us to add Harmony using the "Request Harmony" button above.
