An open blockchain testnet for developers, QaUser1335 enables safe experimentation without real financial risk using native KFZ and Chain ID 66904 for tooling and integration.
QaUser1335 Testnet is a KFZ-denominated test network purpose-built to validate the cross-chain bridge stack in a safe, pre-production environment. It enables developers to run end-to-end tests of smart contracts, bridging/messaging flows, fee handling, and monitoring across multiple networks without real economic risk. KFZ is used only for gas on test transactions and has no real-world value.
Unlike general-purpose public testnets, QaUser1335 Testnet is a focused staging network aligned to the bridge’s production tooling and configurations, making cross-chain QA faster and more predictable. As of Sep 2025, public performance metrics (avg gas cost, block speed, TPS, network activity) are not published; in practice expect very low KFZ gas fees, variable block times, and sporadic throughput typical of a testnet. This specialization lets teams reproduce failure modes and iterate quickly without impacting mainnet liquidity or fee markets.
QaUser1335 Testnet uses KFZ as the gas token for transaction fees. You can obtain KFZ by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge KFZ to QaUser1335 Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser1335 Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
