A testnet blockchain for QaUser5450 (chain ID 73592) using PXB, providing a safe, low-cost environment for development, integration testing, and experimentation.
QaUser5450 is a PXB-denominated testnet built to validate cross-chain bridge workflows, fee logic, and wallet integrations before mainnet release. Primary use cases include deploying and testing smart contracts, simulating cross-chain transfers end-to-end, and running QA with faucet-funded transactions and periodically resettable state.
QaUser5450 is optimized for bridge testing with faucet-funded PXB (near-zero effective gas), stable multi-second block cadence, and deterministic endpoints that make confirmations and retries predictable across runs. Because ephemeral testnets rarely publish stable benchmarks, expect low effective gas costs (faucet PXB), short block times (seconds), integration-grade TPS rather than stress throughput, and activity that spikes during coordinated upgrade windows—verify live figures (avg gas, block speed, TPS, mempool activity) via the testnet explorer when comparing to other networks.
QaUser5450 uses PXB as the gas token for transaction fees. You can obtain PXB by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge PXB to QaUser5450, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser5450 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser5450 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 QaUser5450 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 PXB on QaUser5450, ensure your wallet is connected to the QaUser5450 network, enter the recipient's address, specify the amount of PXB to send, review the gas fee, and confirm the transaction in your wallet.
