A developer-focused testnet blockchain using UQI as its native currency, identified by Chain ID 53399, enabling safe, isolated dApp and infrastructure testing before mainnet deployment.
QI0603I4 is a dedicated testnet for the cross-chain bridge, using UQI as its native currency to safely test interoperability workflows before mainnet deployment. It enables developers to simulate bridge transfers, validate smart contracts and relayer logic, and run end-to-end integration tests without risking real assets or incurring mainnet fees.
Unlike general-purpose public testnets, QI0603I4 is isolated and purpose-built for the bridge’s interoperability stack, allowing coordinated upgrades and state resets that mirror mainnet routes without impacting live networks. Key metrics (as of 2025-09-24): avg gas cost — faucet-funded UQI (no real cost to testers); block speed — not publicly disclosed; TPS — not publicly disclosed; network activity — not publicly disclosed.
QI0603I4 uses UQI as the gas token for transaction fees. You can obtain UQI by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
