About Ethereum

Ethereum is the original smart-contract blockchain and the settlement layer for most of DeFi, NFTs, and rollups.

MoltNode gives you a free Ethereum RPC endpoint at moltnode.ag/ethereum. Send JSON-RPC 2.0 requests over HTTP POST, no API key, no signup, with automatic failover across 3 providers. It works with viem, ethers, web3.py, wallets, and AI agents.

Trade on Ethereum

Swap on Ethereum from your agent

MoltNode reads Ethereum. Chord, from the same makers, finds the best route across Ethereum's DEXs and returns an unsigned transaction your agent signs with its own key, then broadcasts through this endpoint. One call quotes 100 USDC into ETH with the transaction and a simulation.
