A testnet blockchain (Chain ID 82552) powered by the BLOX token, providing a safe, low-cost environment for smart contract and dApp development and validation.
QI0209I2 is a BLOX-denominated testnet that powers pre-production validation for the cross-chain bridge, enabling safe trials of transfers, message passing, and upgrades. It is used by developers to integrate relayers and watchers, run end-to-end route simulations, and perform load/regression testing without real funds; BLOX is faucet-distributed and has no monetary value.
QI0209I2 is unique because it is purpose-built for bridge workflows rather than general-purpose dApp deployment, prioritizing reproducible scenarios, rapid resets, and cross-chain observability. As of September 2025, the network does not publish stable performance benchmarks—average gas cost, block speed, TPS, and activity fluctuate per test cycle and are intentionally kept low-cost and fast for iteration—so it should not be compared to production mainnets. This bridge-first design surfaces edge cases (congestion, delayed finality, route failures) that typical public testnets rarely model.
QI0209I2 uses BLOX as the gas token for transaction fees. You can obtain BLOX by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge BLOX to QI0209I2, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QI0209I2 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
