Frequently asked questions

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.
