An EVM-compatible blockchain shard on QuarkChain Mainnet (Chain ID 100003) offering high throughput via sharding, fast cross-shard transactions, and low transaction fees in QKC.
QuarkChain Shard 2 is an EVM-compatible shard on QuarkChain Mainnet (QKC) designed for high-throughput, low-fee smart contracts and payments. Typical user fees are pennies or less with shard block times generally under ~15 seconds; network-wide throughput scales across shards and has surpassed 10,000+ TPS in public tests, giving Shard 2 ample headroom for DeFi, GameFi, NFTs, and micropayments. It also supports native cross-shard transfers for fast, low-cost movement of assets and liquidity within QuarkChain.
QuarkChain Shard 2 stands out with QuarkChain’s two-layer sharded architecture: a root chain for security/finality and multiple heterogeneous shards for parallel execution, enabling native cross-shard transactions without trusted relays. Developers keep familiar Ethereum tooling (Solidity, Web3, MetaMask) while gaining horizontally scalable throughput and consistently low QKC-denominated gas, which stays stable even during activity spikes thanks to workload distribution across shards. For bridge users, this means faster confirmations, lower costs, and seamless movement of assets across shards and to external ecosystems supported by QuarkChain bridges.
QuarkChain Shard 2 uses QKC as the gas token for transaction fees. You can obtain QKC by bridging from other chains or purchasing using thirdweb Bridge.
To bridge QKC to QuarkChain Shard 2, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QuarkChain Shard 2 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
