Helios Remote Procedure Calls

Helios provides a variety of RPC methods for interacting with the Ethereum network. These methods are exposed via the Client struct. The RPC methods follow the Ethereum JSON RPC Spec. See examples of running remote procedure calls with Helios.

RPC Methods

RPC Method Client Function Description Example
eth_getBalance get_balance Returns the balance of the account given an address. client.get_balance(&self, address: &str, block: BlockTag)
eth_getTransactionCount get_nonce Returns the number of transactions sent from the given address. client.get_nonce(&self, address: &str, block: BlockTag)
eth_getCode get_code Returns the code at a given address. client.get_code(&self, address: &str, block: BlockTag)
eth_call call Executes a new message call immediately without creating a transaction on the blockchain. client.call(&self, opts: CallOpts, block: BlockTag)
eth_estimateGas estimate_gas Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. client.estimate_gas(&self, opts: CallOpts)
eth_getChainId chain_id Returns the chain ID of the current network. client.chain_id(&self)
eth_gasPrice gas_price Returns the current price per gas in wei. client.gas_price(&self)
eth_maxPriorityFeePerGas max_priority_fee_per_gas Returns the current max priority fee per gas in wei. client.max_priority_fee_per_gas(&self)
eth_blockNumber block_number Returns the number of the most recent block. client.block_number(&self)
eth_getBlockByNumber get_block_by_number Returns the information of a block by number. get_block_by_number(&self, block: BlockTag, full_tx: bool)
eth_getBlockByHash get_block_by_hash Returns the information of a block by hash. get_block_by_hash(&self, hash: &str, full_tx: bool)
eth_sendRawTransaction send_raw_transaction Submits a raw transaction to the network. client.send_raw_transaction(&self, bytes: &str)
eth_getTransactionReceipt get_transaction_receipt Returns the receipt of a transaction by transaction hash. client.get_transaction_receipt(&self, hash: &str)
eth_getLogs get_logs Returns an array of logs matching the filter. client.get_logs(&self, filter: Filter)
eth_getStorageAt get_storage_at Returns the value from a storage position at a given address. client.get_storage_at(&self, address: &str, slot: H256, block: BlockTag)
eth_getBlockTransactionCountByHash get_block_transaction_count_by_hash Returns the number of transactions in a block from a block matching the transaction hash. client.get_block_transaction_count_by_hash(&self, hash: &str)
eth_getBlockTransactionCountByNumber get_block_transaction_count_by_number Returns the number of transactions in a block from a block matching the block number. client.get_block_transaction_count_by_number(&self, block: BlockTag)
