A developer-focused testnet blockchain, QaUser1804 (Chain ID 87389), using UOA, enabling safe pre‑production testing, network experimentation, and tooling integration prior to mainnet deployment.
QaUser1804 is a testnet blockchain for pre‑production validation of a cross‑chain bridge, using UOA as a faucet‑distributed, valueless native currency for gas. It is used for end‑to‑end testing of bridging, message passing, liquidity/routing logic, fee quoting, and monitoring before mainnet deployments. As of Sep 2025, official performance metrics (avg gas cost, block speed, TPS, on‑chain activity) are not published and may change across testnet resets.
QaUser1804 is purpose‑built for the bridge stack with mainnet‑parity configurations and rapid iteration, so new bridge features land here first and the network may reset more frequently than general‑purpose testnets. It uses UOA to simulate gas fees without financial risk, enabling high‑volume QA, load testing, and integration checks for wallets, relayers, and explorers. For performance comparisons, treat metrics like TPS, block time, and gas costs as experimental until canonical benchmarks are released.
QaUser1804 uses UOA as the gas token for transaction fees. You can obtain UOA by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge UOA to QaUser1804, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser1804 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser1804 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 QaUser1804 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 UOA on QaUser1804, ensure your wallet is connected to the QaUser1804 network, enter the recipient's address, specify the amount of UOA to send, review the gas fee, and confirm the transaction in your wallet.
