An XDR-based testnet blockchain, QaUser3583 (Chain ID 2715) supports development and QA with safe, non-production experimentation and integration testing.
QaUser3583 is a testnet network for validating cross-chain bridge flows, where XDR is the native gas token. It is used for end-to-end testing of bridge transfers, contract integration, relayer and wallet QA, and performance benchmarking without mainnet risk. As of 2025-09-24, official metrics for avg gas cost, block speed, TPS, and network activity are not published; benchmark via the testnet explorer/RPC using faucet-funded XDR.
QaUser3583 is unique because it uses an XDR-denominated gas model on a testnet dedicated to cross-chain bridge QA, enabling safe, high-frequency experiments. Unlike public mainnets, it supports faucet-based funding and periodic resets, so performance baselines (avg gas cost, block speed, TPS, activity) are not fixed and should be captured per test run. This purpose-built scope minimizes economic risk while preserving realistic integration paths for wallets, relayers, and contracts.
QaUser3583 uses XDR as the gas token for transaction fees. You can obtain XDR by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge XDR to QaUser3583, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select QaUser3583 as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on QaUser3583 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 QaUser3583 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 XDR on QaUser3583, ensure your wallet is connected to the QaUser3583 network, enter the recipient's address, specify the amount of XDR to send, review the gas fee, and confirm the transaction in your wallet.
