Get the number of uncle blocks for a block specified by block hash. Returns the uncle count as a hex string. SKALE chains don't have uncles, so this always returns 0x0. Useful for compatibility with Ethereum tools that expect this method.

Developer Tools

Retrieve the value stored at a specific storage position in a smart contract. Returns the 32-byte value at the specified storage slot as a hex string. Essential for reading contract state variables and analyzing contract storage.

Developer Tools

Compute the Keccak-256 (SHA3) hash of arbitrary input data. Returns the hash as a hex string. Essential for Ethereum signature verification, contract function selectors, and cryptographic operations. Commonly used for generating method signatures and data integrity checks.

Developer Tools

Retrieve the bytecode of a smart contract deployed at a specific address on a blockchain network. Returns the contract code as a hex string. Useful for contract verification, analyzing deployed contracts, and checking if an address contains contract code versus being an externally owned account.

Developer Tools

Get the number of transactions sent from an Ethereum address (nonce). Returns the transaction count as a hex string. Essential for transaction creation and replay protection. Useful for analyzing account activity and determining the next nonce for transaction signing.

Developer Tools

Retrieve the coinbase address of the blockchain node. Returns the address that receives mining rewards and transaction fees. Useful for identifying the node's primary account and fee recipient.

Developer Tools

Retrieve the Ethereum protocol version supported by the blockchain client. Returns the protocol version as a string. Essential for ensuring compatibility between client and network protocol versions.

Developer Tools

Check if the blockchain node is actively listening for network connections from other nodes. Returns a boolean indicating the node's network connectivity status. Useful for monitoring node health and ensuring the RPC endpoint is properly connected to the network.

Developer Tools

Retrieve the version string of the blockchain client software (e.g., Geth, Parity, Besu). Returns detailed version information including client name, version number, and build details. Useful for client identification and compatibility checking.

Developer Tools

Retrieve the network version (chain ID) of the connected blockchain network. Returns the numeric chain identifier as a string. Essential for identifying which blockchain network the node is connected to and ensuring transaction compatibility.

Developer Tools

Retrieve the current gas price suggested by the blockchain network. Returns the gas price in wei as a hex string. Essential for estimating transaction fees and setting appropriate gas prices for transaction submission.

Developer Tools

Retrieve the current block number of a blockchain network. Returns the latest block number as a hex string. Essential for monitoring network progress, transaction confirmation tracking, and determining the current state of the blockchain.

Developer Tools

Retrieve the native cryptocurrency balance of an Ethereum address on a specified blockchain network. Returns the balance in wei (smallest unit) as a hex string. Useful for checking wallet balances, verifying account funds, and monitoring address activity across different blockchains.

Developer Tools

Check if a given chain identifier is supported by the blockchain client. Returns a boolean indicating whether the chain is supported. Returns the normalized chain identifier if the chain is supported.

Developer Tools

Get a list of all supported chains by the blockchain client. Returns an array of chain objects with detailed information about each supported chain.
