Ethereum Mainnet is the primary public Ethereum production blockchain where ETH and tokens carry real economic value, where real assets are traded, and smart contracts run with full decentralization and security. Building on Mainnet gives access to the largest liquidity, most users, and a mature ecosystem—which is critical for many DeFi use cases.
The Ethereum JSON-RPC is a standard protocol that lets dApps and wallets interact with Ethereum nodes to read blockchain state (balances, blocks, logs) or send transactions. Common methods include eth_call, eth_getBalance, eth_getTransactionReceipt, eth_estimateGas, eth_getLogs, and block-query methods (e.g., eth_blockNumber, eth_getBlockByNumber).
1inch offers Web3 RPC API endpoints over HTTP for major EVM chains, as well as WebSocket support for all existing Web3 RPC methods.
Yes. The 1inch Web3 RPC API offers access to historical data (logs, past blocks, events), which lets you query older state and past logs via methods like eth_getLogs.
You can use the 1inch Gas Price API, which provides up-to-date gas price data for various blockchains, including Ethereum.
To avoid rate limits, you can:
Use 1inch Business plan configurator to configure and customize the RPS and Web3 calls based on your needs, rather than public or shared endpoints.
Use WebSockets.
