Space Subnet Testnet is the pre‑production network for the Otherworld Space Subnet, using FUEL as the native gas token to mirror mainnet economics. It enables developers to safely test cross‑chain bridge transfers, liquidity routing, messaging, and contract deployments/integrations without mainnet risk. For current performance baselines (average gas cost, block speed, TPS, and network activity), refer to the live dashboards linked from https://otherworld.network.
It mirrors Space Subnet parameters and FUEL‑based fee markets, giving realistic gas pricing and throughput signals for bridge benchmarking—capabilities generic public testnets often lack. The environment is purpose‑built for cross‑chain workflows on Otherworld, with isolated capacity and frequent upgrade cycles so teams can validate relayers, failure recovery, and end‑to‑end messaging before mainnet. Compare live metrics (avg gas cost, block speed, TPS, activity) via the official resources at https://otherworld.network to evaluate performance against other networks.
Space Subnet Testnet uses FUEL as the gas token for transaction fees. You can obtain FUEL by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge FUEL to Space Subnet Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Space Subnet Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Space Subnet Testnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Space Subnet Testnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send FUEL on Space Subnet Testnet, ensure your wallet is connected to the Space Subnet Testnet network, enter the recipient's address, specify the amount of FUEL to send, review the gas fee, and confirm the transaction in your wallet.
