Testnet is a public, sandbox blockchain network that mirrors mainnet to let you test cross-chain bridge transfers and smart contracts without financial risk. Typical use cases include end-to-end swap rehearsals, integration QA for wallets/relayers/indexers, stress and security testing, and measuring latency and gas before mainnet deployment. It uses valueless MFD from a faucet so developers can deploy and iterate rapidly.
This Testnet is optimized for cross-chain bridge workflows: MFD as the native gas, faucet funding, replay-safe messaging, configurable rate limits, and rapid upgrade cycles for client/bridge releases. Performance is tuned for fast feedback—low average gas cost (near‑zero MFD), second‑level block times, and higher TPS during scheduled stress tests—so activity appears bursty compared to steady‑state mainnets. For apples‑to‑apples comparison, reference live explorer metrics (avg gas cost, block speed, TPS, and active addresses), which fluctuate as parameters are updated.
Testnet uses MFD as the gas token for transaction fees. You can obtain MFD by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge MFD to Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Testnet 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 Testnet 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 MFD on Testnet, ensure your wallet is connected to the Testnet network, enter the recipient's address, specify the amount of MFD to send, review the gas fee, and confirm the transaction in your wallet.
