An EVM-compatible sharded blockchain devnet for Harmony Shard 1, delivering 2-second finality and ultra-low fees via scalable sharding and Effective Proof-of-Stake.
Harmony Devnet Shard 1 is an EVM-compatible shard of the Harmony network (native currency: ONE) that mirrors mainnet conditions for building and testing cross-shard and cross-chain dApps. It delivers ~2-second block times and ultra-low fees (simple transfers ~0.000021 ONE at 1 gwei; most contract calls <0.005 ONE), making it ideal for DeFi, GameFi, NFTs, and micro-payments. Teams use Shard 1 to validate bridge flows and cross-shard messaging before scaling to other shards.
Harmony Devnet Shard 1 stands out with native sharding and seamless cross-shard composability on an EPoS + FBFT consensus with BLS aggregation, while remaining fully EVM-compatible and MetaMask-ready. For performance, expect ~2s blocks and near-instant finality, network-wide target throughput in the thousands TPS (hundreds per shard), and gas prices around 1 gwei with average fees often <0.001 ONE; devnet activity is typically low, enabling consistently fast confirmations.
Harmony Devnet 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 Devnet Shard 1, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Harmony Devnet Shard 1 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
