A testnet blockchain (Chain ID 39585) for developers and QA teams, offering a secure, low-cost environment for pre-production testing, with YRO as the native gas.
QaUser5884 is a dedicated testnet blockchain for the cross-chain bridge, using YRO as the native gas token; YRO is faucet-issued and has no monetary value. Primary use cases include end-to-end bridge flow testing (deposits/withdrawals), integration and wallet QA, relayer/oracle behavior checks, and monitoring/alerts validation before mainnet. Key metrics (as of Sep 2025) for comparison: avg gas cost ~0 in faucet YRO, block speed and TPS vary by test runs, and network activity is intermittent and bursty during QA cycles.
QaUser5884 is unique because it’s a controlled, bridge-focused testnet rather than a general-purpose network, enabling reproducible scenarios, frequent resets, and rapid iteration without economic risk. It emphasizes practical test performance over fixed benchmarks: avg gas cost is effectively ~0 YRO, while block speed, TPS, and activity are intentionally variable to simulate load and failure conditions, making it ideal for cross-chain bridge validation.
QaUser5884 uses YRO as the gas token for transaction fees. You can obtain YRO by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge YRO to QaUser5884, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser5884 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
