An open, developer-focused testnet blockchain, QaUser2491 uses GCW (Chain ID 77209) for risk-free smart contract testing, dApp experimentation, and tooling integration before mainnet deployment.
QaUser2491 is a GCW-denominated testnet environment for the cross-chain bridge, designed to validate bridge logic, transaction routing, and security before mainnet deployment. Primary use cases include end-to-end bridge simulations, smart-contract QA, relayer and wallet integration testing, and stress/fault-injection runs using valueless GCW for gas.
Compared to general-purpose testnets, QaUser2491 is a controlled, bridge-focused network that prioritizes reproducible cross-chain scenarios and rapid iteration over economic decentralization. Performance metrics for comparison (as of 2025-09): avg gas cost N/A (testnet GCW), block speed N/A, TPS N/A, activity low/QA-driven; check your team’s explorer or telemetry dashboards for live data.
QaUser2491 uses GCW as the gas token for transaction fees. You can obtain GCW by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge GCW to QaUser2491, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser2491 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
