An EVM-compatible sharded blockchain, Harmony Shard 1 delivers low fees and 2-second finality via Effective Proof-of-Stake, enabling cross-shard interoperability and scalable dApps with ONE.
Harmony Shard 1 is an EVM-compatible shard of the Harmony mainnet (ONE) used for smart contracts, DeFi, and NFTs; since Harmony’s 2023–2024 consolidation of activity to Shard 0, Shard 1 primarily serves legacy contracts and balances. Performance profile: ~2s block time, 1 gwei default gas price, typical fees ≈0.000021–0.0003 ONE per tx; current Shard 1 activity and TPS are near zero relative to Shard 0. For bridging, confirm your route explicitly supports Shard 1, as many bridges and RPC endpoints default to Shard 0.
Harmony Shard 1 inherits Harmony’s unique EPoS validator design with BLS signature aggregation and a sharded, EVM-compatible architecture, delivering fast finality (~2s blocks) and ultra-low fees (1 gwei gas; simple transfers ≈0.000021 ONE). Compared to other L1 networks, it offers lower latency and costs, but in 2025 its observed usage and TPS on Shard 1 are minimal because most liquidity, validators, and bridge support concentrate on Shard 0. This makes Shard 1 best suited for accessing legacy state or assets while enjoying the same tooling as Ethereum.
Harmony Shard 1 uses ONE as the gas token for transaction fees. You can obtain ONE by bridging from other chains or purchasing using thirdweb Bridge.
To bridge ONE to Harmony Shard 1, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Harmony Shard 1 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Harmony Shard 1 you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Harmony Shard 1 to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send ONE on Harmony Shard 1, ensure your wallet is connected to the Harmony Shard 1 network, enter the recipient's address, specify the amount of ONE to send, review the gas fee, and confirm the transaction in your wallet.
