JSON-RPC API

This section provides an interactive reference for the Monad's JSON-RPC API. For a simple example, try getting the latest block.

Debug methods

debug_getRawBlock - returns an RLP-encoded block
debug_getRawHeader - returns an RLP-encoded header
debug_getRawReceipts - returns an array of EIP-2718 binary-encoded receipts
debug_getRawTransaction - returns an EIP-2718 binary-encoded transaction
debug_traceBlockByHash - returns the tracing result by executing all transactions in the block; supports callTracer or prestateTracer
debug_traceBlockByNumber - same
debug_traceCall - returns the tracing result by executing an eth_call
debug_traceTransaction - returns all the traces of a given transaction

eth_blockNumber - returns the most recent block number
eth_call - simulates calling a smart contract without writing a transaction
eth_chainId - returns the chainId in hex
eth_estimateGas - estimates the gasLimit for a smart contract call to run successfully, using simulation and binary search
eth_feeHistory - returns transaction base fee per gas and effective priority fee per gas for the block range
eth_gasPrice - returns the current price per gas in MON-wei in hex
eth_getBalance - returns the balance of an account in MON-wei in hex
eth_getBlockByHash - returns a block
eth_getBlockByNumber - returns a block
eth_getBlockReceipts - returns the receipts of a block
eth_getBlockTransactionCountByHash - returns the number of transactions in a block
eth_getBlockTransactionCountByNumber - returns the number of transactions in a block
eth_getTransactionByBlockHashAndIndex - returns a transaction
eth_getTransactionByBlockNumberAndIndex - returns a transaction
eth_getTransactionByHash - returns a transaction
eth_getTransactionCount - returns the nonce of an address
eth_getTransactionReceipt - returns the receipt for a transaction
eth_maxPriorityFeePerGas - returns the current maxPriorityFeePerGas in MON-wei
eth_sendRawTransaction
eth_syncing - indicates if node is currently syncing (RPC providers should ensure no node that returns true for this call is serving users)
