An EVM-compatible mainnet blockchain powering the Otherworld Network, Space Subnet delivers fast finality and low-cost transactions for Web3 gaming, with FUEL as native gas.
Space Subnet is a mainnet, app-specific chain in the Otherworld Network that uses FUEL as its native gas to power high-throughput on-chain games, NFTs, and creator economies. It enables low-cost microtransactions, real-time gameplay logic, and NFT minting/trading with cross-chain bridging to major L1/L2 ecosystems. Key performance highlights (by design): sub-cent average gas fees, sub-second block times, high TPS capacity, and support for sustained high-frequency activity typical of gaming workloads.
Space Subnet is unique for its purpose-built architecture around the FUEL gas token, delivering predictable low fees and low-latency finality for always-on gameplay. Unlike generalized L1s, it targets sub-second blocks and sub-cent gas while integrating first-class cross-chain bridging, so assets and liquidity move seamlessly. App-specific resource isolation minimizes congestion from other workloads, preserving high TPS headroom and stable performance during activity spikes.
Space Subnet uses FUEL as the gas token for transaction fees. You can obtain FUEL by bridging from other chains or purchasing using thirdweb Bridge.
