An EVM-compatible Layer-1 test network for Fantom (chain ID 4002) offering aBFT Lachesis consensus, fast finality, and ultra-low-cost smart contract testing with FTM.
Fantom Testnet is a public EVM-compatible network mirroring Fantom Opera’s Lachesis aBFT consensus, letting developers safely stage dApps, smart contracts, and cross-chain integrations with faucet FTM. Typical performance is ~1s block time with ~1–2s finality and burst capacity in the thousands TPS (hundreds TPS sustained in practice), while fees are effectively zero; this enables realistic load testing and much faster iteration than Ethereum testnets (~12s blocks).
It combines Lachesis aBFT finality (~1–2s) and ~1s block production with full EVM equivalence, delivering mainnet-like throughput (hundreds sustained, thousands TPS headroom) at near-zero cost on testnet. Lower, more predictable activity reduces congestion, so confirmations remain fast and stable compared to many public testnets (e.g., ~12s blocks and variable gas on Ethereum), making bridge and dApp QA significantly quicker.
Fantom Testnet uses FTM as the gas token for transaction fees. You can obtain FTM by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge FTM to Fantom Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Fantom Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
