An EVM-compatible blockchain testnet, Conflux eSpace (Chain ID 71) delivers high throughput, low fees, and fast finality via Tree-Graph consensus using CFX.
Conflux eSpace (Testnet) is the EVM-compatible test network of Conflux that mirrors mainnet eSpace and uses CFX for gas, enabling safe dApp and cross-chain bridge development. Typical testnet metrics for comparison: ~1–2s block time, hundreds of TPS sustained, gas price often ~1 GDrip (e.g., transfer ≈0.000021 CFX; typical contract call <0.001 CFX), with activity spiking during hackathons and releases. Primary use cases include deploying and auditing Solidity contracts, testing Core Space↔eSpace native bridging, and validating wallets, oracles, and indexing pipelines before mainnet launch.
It’s unique for its dual-space architecture—Core Space plus eSpace—with a trust-minimized native bridge between them, all secured by Conflux’s Tree-Graph consensus for fast finality and high throughput. In practice, the testnet delivers faster blocks (~1–2s vs ~12s on Ethereum L1), lower fees (gas often ~1 GDrip leading to sub-milli CFX per tx), and full Ethereum tooling parity (Solidity, MetaMask, Hardhat), making it well-suited for low-latency, cost-sensitive EVM dApps and cross-space workflows.
Conflux eSpace (Testnet) uses CFX as the gas token for transaction fees. You can obtain CFX by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge CFX to Conflux eSpace (Testnet), connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Conflux eSpace (Testnet) as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
