A developer-focused testnet blockchain, QI0520I2 (chain ID 46145) uses YZG for gas and provides an isolated, low-cost environment for safe smart-contract and dApp testing.
QI0520I2 is a dedicated testnet chain for staging and validating the cross‑chain bridge; its native currency is YZG distributed via faucet and has no real‑world value. It is used for safe contract deployment, end‑to‑end bridge simulations (asset transfers and message passing), relayer/integration testing, and fee‑model dry runs; public performance metrics (avg gas cost, block speed, TPS, activity) are not published and can change between test cycles.
QI0520I2 is purpose‑built for the bridge, designed to mirror production routing, fee logic, and message formats in a controlled sandbox to enable reproducible cross‑chain scenarios and rapid iteration. As a test‑only network, it is frequently reset and tuned, so performance metrics (avg gas cost, block speed, TPS, activity) are intentionally variable and not suitable for direct comparison with mainnets or public testnets.
QI0520I2 uses YZG as the gas token for transaction fees. You can obtain YZG by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge YZG to QI0520I2, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QI0520I2 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
