A testnet blockchain with Chain ID 28408 and BLY, focused on isolated developer validation and tooling experiments without cross-chain interoperability.
QIM2405062 NO INTEROP is a BLY-denominated testnet used by the cross-chain bridge as an isolated environment for smart contract and transaction validation. It is designed for developer use cases such as staging deployments, fee and nonce testing, and UI/flow checks without any cross-chain transfers or messages enabled. Funds are test BLY only and the network may be reset during routine testnet wipes.
Its key differentiator is that interoperability is deliberately disabled—bridge transfers, external messaging, and remote calls are blocked in the bridge configuration and network settings—creating a fully sandboxed chain for deterministic testing. Compared to other testnets, it prioritizes isolation over connectivity and may use controlled upgrades/resets to keep state reproducible. As of September 2025, no public benchmarks exist for average gas cost, block speed, TPS, or on-chain activity; treat performance as variable and measure via local RPC during tests.
QIM2405062 NO INTEROP uses BLY as the gas token for transaction fees. You can obtain BLY by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
