An experimental blockchain testnet for developers, QaUser0417 uses HAR-denominated gas and Chain ID 58050 to safely test dApps and transactions without real-value risk.
QaUser0417 is a testnet chain for the cross-chain bridge that uses HAR as its native gas token. It is used to safely test cross-chain asset transfers, message passing, and smart-contract integrations, including fee behavior and failure recovery, before mainnet deployment. As of Sep 2025, no official public benchmarks (avg gas cost, block speed, TPS, activity) are published; treat gas as near-zero and performance variable, and measure in real time via your node’s RPC (block interval for speed, tx counts for TPS, gasPrice for cost).
QaUser0417 is purpose-built for bridge QA rather than production use, prioritizing deterministic testing, rapid iteration, and safe chain resets over economic finality. It standardizes on HAR for consistent gas accounting and exposes bridge-centric telemetry (message status, proofs, retries) to debug and validate cross-chain flows. Unlike general public testnets that advertise fixed TPS or block times, QaUser0417 emphasizes reproducible cross-chain validation and expects developers to benchmark live performance (gas, block speed, TPS, activity) from their own RPC measurements.
QaUser0417 uses HAR as the gas token for transaction fees. You can obtain HAR by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge HAR to QaUser0417, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser0417 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser0417 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 QaUser0417 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 HAR on QaUser0417, ensure your wallet is connected to the QaUser0417 network, enter the recipient's address, specify the amount of HAR to send, review the gas fee, and confirm the transaction in your wallet.
