JSON-RPC API

The JSON-RPC is a stateless, lightweight remote procedure call (RPC) protocol. It defines several data structures and the rules around their processing. It is transport agnostic because the concepts can be used within the same process, over sockets, HTTP, or in various message-passing environments. It uses JSON (RFC 4627) as data format.

This page deals with the JSON-RPC API used by EVM execution clients.

JSON-RPC Methods According to Ethereum Client API

Method	Description	Status
eth_accounts	Returns a list of addresses owned by client	✅
eth_blockNumber	Returns the number of most recent block.	✅
eth_call	Executes a new message call immediately without creating a transaction on the blockchain	✅
eth_chainId	Returns the chain ID of the current network	✅
eth_coinbase	_Returns the client Coinbase address (Response is always the Common Address of the IOTA EVM)__	✅
eth_estimateGas	Generates and returns an estimate of how much gas is necessary to allow the transaction to complete.	✅
eth_gasPrice	Returns the current price per gas in wei	✅
eth_getBalance	Returns the balance of the account of given address	✅
eth_getBlockByHash	Returns information about a block by hash	✅
eth_getBlockByNumber	Returns information about a block by number	✅
eth_getBlockReceipts	Returns the receipts of a block by number or hash	✅
eth_getBlockTransactionCountByHash	Returns the number of transactions in a block from a block matching the given block hash	✅
eth_getBlockTransactionCountByNumber	Returns the number of transactions in a block matching the given block number	✅
eth_getCode	Returns code at a given address	✅
eth_getCompilers	_Returns a list of available compilers in the client (Response is always empty on IOTA EVM).	✅
eth_getFilterChanges	Polling method for a filter, which returns an array of logs which occurred since last poll	❌
eth_getFilterLogs	Returns an array of all logs matching filter with given id. Can compute the same results with an eth_getLogs call	❌
eth_getLogs	Anytime a transaction is mined, we can see event logs for that transaction by making a request to eth_getLogs and then take actions based off those results	✅
eth_getStorageAt	Returns the value from a storage position at a given address	✅
eth_getTransactionByBlockHashAndIndex	Returns information about a transaction by block hash and transaction index position	✅
eth_getTransactionByBlockNumberAndIndex	Returns information about a transaction by block number and transaction index position	✅
eth_getTransactionByHash	Returns the information about a transaction requested by transaction hash	✅
eth_getTransactionCount	Returns the number of transactions sent from an address	✅
eth_getTransactionReceipt	Returns the receipt of a transaction by transaction hash	✅
eth_getUncleByBlockHashAndIndex	Returns information about a uncle of a block by hash and uncle index position (Response is always null on IOTA EVM)	✅
eth_getUncleByBlockNumberAndIndex	Returns information about a uncle of a block by number and uncle index position (Response is always null on IOTA EVM)	✅
eth_getUncleCountByBlockHash	Returns the number of uncles in a block from a block matching the given block hash (Response is always 0x0 on IOTA EVM)	✅
eth_getUncleCountByBlockNumber	Returns the number of uncles in a block from a block matching the given block number (Response is always 0x0 on IOTA EVM)	✅
eth_hashrate	Returns the number of hashes per second that the node is mining with (Response is always 0 on IOTA EVM)	✅
eth_mining	Returns whether the client is actively mining new blocks (Response is always false on IOTA EVM)	✅
eth_newBlockFilter	Creates a filter in the node, to notify when a new block arrives	❌
eth_newFilter	Creates a filter object, based on filter options, to notify when the state changes (logs)	❌
eth_newPendingTransactionFilter	Creates a filter in the node, to notify when new pending transactions arrive	❌
eth_protocolVersion	Returns the current Ethereum protocol version	✅
eth_sendRawTransaction	Submits a raw transaction	✅
eth_sendTransaction	Signs and submits a transaction	✅
eth_sign	Returns an EIP-191 signature over the provided data.	✅
eth_signTransaction	Signs and submits a transaction	✅
eth_subscribe	Creates a new subscription for particular events. The node returns a subscription ID. For each event that matches the subscription, a notification with relevant data is sent together with the subscription ID. Supported events are newHeads and logs	✅
eth_syncing	Returns an object with data about the sync status or false-copy (Response is always false on IOTA EVM)	✅
eth_uninstallFilter	Uninstalls a filter with given id	❌

JSON-RPC methods according to the Debug Module API

Method	Description	Status
debug_traceBlockByNumber	Returns tracing results by executing all transactions in the specified block number.	✅
debug_traceBlockByHash	Returns tracing results by executing all transactions in the block specified by the block hash.	✅
debug_traceTransaction	Returns tracing results for the specified transaction.	✅
debug_getRawBlock	Returns an RLP-encoded block.	✅

JSON-RPC methods according to the Net Module API

Method	Description	Status
net_listening	_Returns true if client is actively listening for network connections (Response is always true on IOTA EVM)__	✅
net_peerCount	_Returns number of peers currently connected to the client (Response is always 0x0 on IOTA EVM)__	✅
net_version	Returns the current network ID.	✅

JSON-RPC methods according to the Web3 Module API

Method	Description	Status
web3_clientVersion	Returns the current client version (Response is always wasp/evmproxy on IOTA EVM)	✅
web3_sha	Returns Keccak-256 (not the standardized SHA3-256) of the given data	✅
