QaUser4 Testnet is a controlled pre-production blockchain environment for the cross-chain bridge, using NLD as the native gas token with no real-world value. It is used by developers to test bridge transfers, cross-chain messaging, contract deployments, wallet flows, and gas-fee behavior without risking mainnet funds.
Unlike public testnets, QaUser4 Testnet is scoped to cross-chain bridge QA and may operate with restricted access and controlled infrastructure to enable reproducible end-to-end scenarios and fault testing; no public info URL or explorer is provided. For performance comparison, up-to-date metrics are not publicly published as of 2025-09-24—average gas cost, block time, TPS, and on-chain activity are N/A and should be benchmarked via the provided RPC during tests.
QaUser4 Testnet uses NLD as the gas token for transaction fees. You can obtain NLD by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge NLD to QaUser4 Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser4 Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser4 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 QaUser4 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 NLD on QaUser4 Testnet, ensure your wallet is connected to the QaUser4 Testnet network, enter the recipient's address, specify the amount of NLD to send, review the gas fee, and confirm the transaction in your wallet.
