A developer-focused testnet blockchain with Chain ID 33100 using MBP, enabling low-cost, risk-free dApp and smart contract testing before mainnet deployment.
QaUser7864 is an MBP-denominated testnet purpose-built to validate cross-chain bridge workflows end-to-end without mainnet risk. Primary use cases include simulating token and message transfers, relayer behavior, fee routing, and contract upgrades under varying latency/failure scenarios. As a testnet, average gas cost is effectively near-zero MBP (via faucet), while block speed, TPS, and on-chain activity are configuration-dependent and typically bursty during QA runs.
QaUser7864 is unique as a controlled MBP testnet optimized for reproducible cross-chain bridge testing rather than production throughput. It emphasizes tunable performance metrics—negligible average gas cost, adjustable block speed and gas limits for high-TPS stress, and scripted activity bursts—enabling apples-to-apples comparisons under fast, normal, and congested conditions. The environment supports resettable state and reversible deployments for safe iteration that you cannot perform on public mainnets.
QaUser7864 uses MBP as the gas token for transaction fees. You can obtain MBP by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge MBP to QaUser7864, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser7864 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser7864 you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add QaUser7864 to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send MBP on QaUser7864, ensure your wallet is connected to the QaUser7864 network, enter the recipient's address, specify the amount of MBP to send, review the gas fee, and confirm the transaction in your wallet.
