An EVM-compatible testnet for the Fuse Network, Fuse Sparknet uses SPARK and offers fast, low-cost transactions for testing web3 payments and business applications.
Fuse Sparknet is Fuse Network’s public EVM testnet (native coin: SPARK) that mirrors mainnet features for safe deployment and cross‑chain integration testing. It is optimized for payments, loyalty/NFT programs, Account Abstraction wallets, and gasless/meta‑transaction flows, letting teams validate UX and bridge routes before mainnet. Performance targets ~5s block time, typical gas price around 1 gwei (~0.000021 SPARK for a 21k‑gas transfer) and effective throughput in the tens of TPS, with activity focused on developer testing rather than production traffic.
Sparknet is uniquely payment‑first: it supports gasless transactions via relayers, fee sponsorship, and AA/ERC‑4337 tooling, enabling end‑to‑end testing of real‑world payment experiences that generic testnets don’t prioritize. It offers faster blocks (~5s vs ~12s on Ethereum), ultra‑low fees (≈1 gwei baseline; sub‑cent equivalent), and full EVM compatibility for quick porting of Solidity apps and bridge contracts. Consistent, low‑contention testnet activity makes benchmarking practical (tens of TPS observed under typical settings) while preserving mainnet‑like behavior for reliable pre‑production validation.
Fuse Sparknet uses SPARK as the gas token for transaction fees. You can obtain SPARK by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge SPARK to Fuse Sparknet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Fuse Sparknet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Fuse Sparknet 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 Fuse Sparknet 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 SPARK on Fuse Sparknet, ensure your wallet is connected to the Fuse Sparknet network, enter the recipient's address, specify the amount of SPARK to send, review the gas fee, and confirm the transaction in your wallet.
