A scalable multi-layer, multi-chain Thinkium mainnet (Chain ID 70103) offering hierarchical sharding and native cross-chain interoperability with low fees paid in TKM.
Thinkium Chain 103 is a production mainnet shard of the Thinkium Network that uses TKM as its native gas and settlement asset. It powers smart contracts and cross-chain asset transfers for bridges, scalable DeFi, gaming, NFTs, and enterprise applications. For comparison, avg gas cost, block speed, TPS, and on-chain activity are shard-specific and not canonically published; consult the official Thinkium explorer via https://thinkium.net/ for current Chain 103 metrics.
Thinkium Chain 103 is unique for its hierarchical multi-chain architecture: it runs in parallel with other Thinkium shards and supports native cross-chain messaging under a shared protocol, enabling horizontal scaling. Unlike single-chain networks that quote one TPS or block time, Thinkium’s metrics (fees in TKM, block intervals, throughput, and activity) are configured per shard, allowing capacity to grow elastically as demand rises. This design enables seamless in-network bridging and mitigates bottlenecks common to monolithic L1s.
Thinkium Chain 103 uses TKM as the gas token for transaction fees. You can obtain TKM by bridging from other chains or purchasing using thirdweb Bridge.
