A testnet blockchain, QI1220s1 (Chain ID 42451) uses BKX as its native currency and enables safe pre-production deployment, integration testing, and transaction experimentation.
QI1220s1 is a BKX-denominated testnet that mirrors the production cross‑chain bridge stack for safe, end‑to‑end validation. It is used for CI/integration testing of deposits/withdrawals, message passing, fee routing, contract upgrades, and failure‑recovery drills, with faucet BKX covering gas. Teams benchmark block time, TPS, and gas cost here before promoting changes to mainnet.
QI1220s1 runs with a controlled validator set, deterministic resets, and reproducible state snapshots, enabling repeatable experiments and bridge‑specific failure‑mode testing. Key metrics to monitor for comparison are avg gas cost (near‑zero effective due to faucet BKX), block speed (seconds‑level), TPS (targets in the hundreds during stress runs), and validator/relayer activity (bursty during QA windows); confirm current values via your explorer or metrics tooling. It also exposes bridge‑focused telemetry (queue depth, finality lag, relayer success rate) to tune cross‑chain routing and reliability.
QI1220s1 uses BKX as the gas token for transaction fees. You can obtain BKX by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge BKX to QI1220s1, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QI1220s1 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
