Fluent RPC Endpoint

Flat-rate Fluent RPC provider and Fluent RPC node access: free tier, no KYC, HTTP & WebSocket. Fluent mainnet chain ID 25363.

Fluent is an Ethereum-compatible execution network that blends EVM and Rust-based contracts on chain ID 25363. Standard Ethereum JSON-RPC tooling works, and ETH pays gas.

About Fluent

Fluent is designed for applications that combine Solidity and Rust contracts in one execution environment. Its EVM compatibility means familiar wallets, libraries and JSON-RPC methods work against the network, while Fluentbase contracts can share state with Solidity contracts.

The network uses ETH as its native gas token and exposes standard eth_* methods over HTTP and WebSocket. Verify Fluent's bridge and finality documentation before moving assets between Fluent and other networks.

Common Use Cases on Fluent

• Solidity and Rust smart contracts
• EVM-compatible DeFi and consumer applications
• Cross-runtime applications using Fluentbase
• Wallets, indexers and EVM developer tooling

Fluent Ecosystem

Fluent's ecosystem centers on blended EVM and Rust execution, letting teams build applications that use both contract runtimes without leaving the network.
