A public testnet blockchain for developers, John’s Testnet uses FLG as its native currency and Chain ID 70038 for safe transaction and tooling experimentation.
John's Testnet is a FLG-denominated blockchain test network for safe pre-production validation of smart contracts, wallets, and cross-chain bridge workflows. It enables end-to-end integration, transaction simulation, and tooling/SDK validation in a controlled, non-production environment with no real-value risk. Teams use it to automate QA pipelines and rehearse upgrade procedures before mainnet release.
John's Testnet is optimized for testing rather than performance: block speed and TPS are intentionally variable by configuration and test load, and on-chain activity is sporadic and developer-driven. Average gas cost is paid in test FLG (no monetary cost); as of September 2025 there is no official info URL or published metrics (avg gas, block time, TPS) for apples-to-apples comparison with public networks. This flexible profile—plus isolated FLG accounting—makes it well-suited to bridge scenario testing, fault injection, and reproducible cross-chain experiments.
John's Testnet uses FLG as the gas token for transaction fees. You can obtain FLG by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge FLG to John's Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select John's Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
