QaUser6991 is a testnet network for the cross-chain bridge that uses HIO as the native gas token to safely validate cross-chain transactions before mainnet. It supports end-to-end bridge flow testing, smart contract dry-runs, wallet/dApp QA, and fee/latency profiling without risking real assets.
Unlike production networks, QaUser6991 is a dedicated bridge testnet where transactions use valueless HIO for fees and testnets typically offer rapid confirmations for fast iteration and safe failure handling. As of Sep 2025, no official performance metrics are published (avg gas cost, block speed, TPS, activity); in practice gas is effectively negligible and latency/throughput vary, so benchmark via your RPC to compare against your target mainnet.
QaUser6991 uses HIO as the gas token for transaction fees. You can obtain HIO by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge HIO to QaUser6991, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser6991 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
