A testnet blockchain, QaUser4251 (Chain ID 92847), uses ERU as its native currency to provide a safe, non-production environment for application validation and protocol testing.
QaUser4251 is a dedicated testnet for a cross-chain bridge, using ERU as the native gas token. It enables safe end-to-end QA and developer integration to simulate cross-chain transfers, confirmations, fee handling, and failure recovery without financial risk. Metrics for comparison: avg gas cost $0 (faucet ERU; no fiat value), block speed/TPS/activity not publicly published as of Sep 2025.
Unlike public testnets, QaUser4251 is purpose-built for this bridge, featuring ERU-only economics and controlled participation to mirror pre-production flows safely. Its focus is deterministic, low-cost validation of bridge logic rather than headline throughput, so official performance benchmarks are intentionally not promoted. Key metrics at a glance: avg gas cost $0 (faucet), block speed/TPS unpublished, activity limited to QA/developer workloads.
QaUser4251 uses ERU as the gas token for transaction fees. You can obtain ERU by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
