Frequently asked questions

QI0521s5t is the dedicated blockchain testnet for the cross-chain bridge, using the VTV token as the native gas currency. It is used for end-to-end dry runs of deposits/withdrawals, smart-contract and relayer/oracle integration, monitoring, and upgrade rehearsals with faucet-funded, zero-economic-value tokens. As of 2025-09-24, no official averages for performance metrics (avg gas cost, block speed, TPS, network activity) are publicly documented; measure them during your tests via RPC to establish baselines.

Compared to general-purpose public testnets, QI0521s5t is narrowly scoped to the bridge stack, offering a low-noise environment that improves reproducibility for benchmarking and failure injection. It uses VTV for gas during tests and supports rapid resets/upgrades, so changes can be validated without impacting mainnet users. Because of this controlled design, headline metrics (avg gas cost, block speed, TPS, activity) are intentionally variable across releases and validator settings; rely on your own captured measurements rather than public leaderboards for comparison.

QI0521s5t uses VTV as the gas token for transaction fees. You can obtain VTV by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).

To bridge VTV to QI0521s5t, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QI0521s5t as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on QI0521s5t 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 QI0521s5t 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 VTV on QI0521s5t, ensure your wallet is connected to the QI0521s5t network, enter the recipient's address, specify the amount of VTV to send, review the gas fee, and confirm the transaction in your wallet.
