Overview

This API provides JSON-RPC 2.0 endpoints for interacting with the DeFi Oracle Meta Mainnet (ChainID 138).

Authentication

Currently, the public RPC endpoint does not require authentication. Rate limiting is applied per IP address.

Note

: For production applications, consider using authenticated endpoints or API keys.

JSON-RPC Methods

Standard Ethereum Methods

eth_blockNumber - Get latest block number
eth_getBalance - Get account balance
eth_getTransactionCount - Get transaction count (nonce)
eth_sendTransaction - Send transaction
eth_call - Execute call without creating transaction
eth_getTransactionReceipt - Get transaction receipt
eth_getLogs - Get event logs
