A testnet for the 0G blockchain, Galileo uses OG as its native currency (Chain ID 16601) and supports low-cost dApp testing and network upgrade staging.
0G-Galileo-Testnet is the public pre-production network for the 0G protocol, using test OG as the native gas token to trial dApps, cross-chain bridge flows, validators, and indexers before mainnet. As of Sep 2025, official baseline performance metrics (avg gas cost, block speed, TPS, on-chain activity) are not finalized and may change with frequent parameter updates and resets—treat any explorer figures as indicative only, not for apples-to-apples comparisons with mainnets.
0G-Galileo-Testnet is designed to stress-test 0G’s data- and AI-centric architecture, emphasizing high-throughput data availability, large-payload transactions, and storage/messaging primitives rather than only simple token transfers. Compared with many public testnets, Galileo typically targets low fees and fast blocks for rapid iteration, but observed metrics (avg gas, block time, TPS, activity) are intentionally fluid in test conditions—check the current explorer or announcements before benchmarking or capacity planning.
0G-Galileo-Testnet uses OG as the gas token for transaction fees. You can obtain OG by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge OG to 0G-Galileo-Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select 0G-Galileo-Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on 0G-Galileo-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 0G-Galileo-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 OG on 0G-Galileo-Testnet, ensure your wallet is connected to the 0G-Galileo-Testnet network, enter the recipient's address, specify the amount of OG to send, review the gas fee, and confirm the transaction in your wallet.
