A public testnet blockchain for pre-production validation, QaUser3938 uses HTO as its native currency and Chain ID 72647 to enable safe, low-risk developer experimentation.
QaUser3938 is the HTO-denominated testnet for the cross-chain bridge, designed to validate asset transfers, message passing, and contract integrations before mainnet deployment. It uses faucet-distributed HTO (no real value) so developers can safely test wallets, relayers, fee estimation, and failure recovery end-to-end.
Unlike general-purpose testnets, the QaUser3938 testnet is an isolated, bridge-focused network that aligns upgrades and contract versions with the bridge release cycle for reproducible results. As of Sep 2025, public performance benchmarks are not published—average gas cost, block speed, TPS, and network activity are unspecified—so teams should benchmark via the network’s RPC to compare against other chains.
QaUser3938 uses HTO as the gas token for transaction fees. You can obtain HTO by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge HTO to QaUser3938, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser3938 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser3938 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 QaUser3938 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 HTO on QaUser3938, ensure your wallet is connected to the QaUser3938 network, enter the recipient's address, specify the amount of HTO to send, review the gas fee, and confirm the transaction in your wallet.
