An EVM-compatible blockchain testnet for SX Network (Chain ID 647), optimized for low-cost, fast-finality prediction markets and DeFi, using SX as its native currency.
SX Network Testnet is the public EVM-compatible sandbox for the SX blockchain (native currency: SX), mirroring mainnet to test prediction markets, DeFi apps, oracles, bridges, and wallets without real funds. Gas is faucet-funded and effectively $0, with seconds-level block times that enable faster iteration than Ethereum L1 (~12s blocks and much higher fees), and activity is developer-focused rather than user-volume driven.
Unlike generic testnets, SX Network Testnet is purpose-built for on-chain prediction markets and sports-betting workloads, pairing low-fee EVM execution with fast, IBFT-style finality and full Ethereum tooling (Solidity, Hardhat/Foundry, MetaMask). In practice you get seconds-level confirmations, near-zero transaction costs, and ample TPS headroom for load-testing bots and bridge flows—whereas L1 environments face higher fees, slower blocks, and congestion; check the official explorer for live throughput and block-time metrics.
SX Network Testnet uses SX as the gas token for transaction fees. You can obtain SX by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge SX to SX Network Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select SX Network Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on SX Network 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 SX Network 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 SX on SX Network Testnet, ensure your wallet is connected to the SX Network Testnet network, enter the recipient's address, specify the amount of SX to send, review the gas fee, and confirm the transaction in your wallet.
