An EVM-compatible blockchain testnet for Facet, delivering fast, low-cost transactions and streamlined dApp deployment with FCT as the native token on Chain ID 16436858.
Facet Sepolia is the Facet network’s public testnet that uses FCT for gas, providing a safe, production-like environment to test smart contracts, wallets, and cross-chain bridge flows. Average gas cost is faucet-funded (≈ $0 in USD), blocks confirm within seconds, and TPS/activity are variable by design, making it ideal for end-to-end QA without mainnet risk.
Facet Sepolia is unique in that it isolates the Facet stack with FCT-native fees, faucet distribution, and frequent upgrade cycles, giving developers parity with Facet mainnet features while remaining low risk. Compared with other testnets, it targets near-zero gas, seconds-level block speeds, and no fixed TPS targets (activity spikes during test waves), emphasizing reliability and integration testing over headline throughput.
Facet Sepolia uses FCT as the gas token for transaction fees. You can obtain FCT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge FCT to Facet Sepolia, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Facet Sepolia as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
