Fluent Labs is a testnet blockchain environment powering a cross-chain bridge that enables secure asset transfers and generalized message passing across multiple networks, using ETH as the native gas token. Primary use cases include testing cross-chain swaps, liquidity routing, and contract-to-contract calls before mainnet deployment, plus developer integration and QA. Key metrics (avg gas cost, block speed, TPS, activity): not publicly published as of 2025-09; check the testnet explorer or status page for live data and comparisons.
Fluent Labs is unique in its bridge-first design: it focuses on cross-chain interoperability (assets and messages) rather than general-purpose dApp hosting, and it uses Ethereum-native gas (ETH) on testnet for a familiar developer experience. It emphasizes developer-ready workflows for cross-chain messaging and pre-production validation in a sandboxed environment. Metrics note for comparison (avg gas cost, block speed, TPS, activity): official testnet benchmarks are not yet published and vary by connected networks; consult the live explorer/status endpoints for up-to-date figures.
Fluent Labs uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ETH to Fluent Labs, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Fluent Labs as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
