Fetches live ETH balance and ERC20 token balances for an Ethereum-compatible wallet address in a single call

Fetches the ERC20 token balance (name, symbol, decimals, raw balance) for any Ethereum wallet address on multiple chains via live RPC eth_call

Resolves a .eth ENS name to its Ethereum address (and resolver info), or resolves an Ethereum address to its primary .eth name, via eth_call on a live Ethereum RPC.

Detects whether an Ethereum address is a proxy contract and identifies its pattern (EIP-1967, UUPS, Transparent/slot0) along with the implementation address

Resolves an ENS .eth name to an Ethereum address, or reverse-resolves an Ethereum address to its primary .eth name, via live eth_call on multiple networks

Returns on-chain details for a specific smart contract address, including token standards (ERC-20, ERC-721, ERC-1155), interfaces, and bytecode size.

Fetches NFT metadata, traits, and image URI for any ERC721 or ERC1155 token by contract address and token ID via live Ethereum RPC with IPFS resolution

Fetches the mined transaction receipt for a given Ethereum transaction hash, including status, gas used, and emitted event logs

Reads a raw 32-byte storage slot from any Ethereum-compatible smart contract at a given block using eth_getStorageAt

Fetches and decodes ERC20 Transfer event logs via eth_getLogs, returning sender, recipient, and amount for a given token contract or wallet address across multiple EVM networks

Returns the current on-chain owner address of a specific ERC721 NFT by querying ownerOf via eth_call

Fetches full on-chain transaction details for a given Ethereum transaction hash via eth_getTransactionByHash

Fetches the on-chain transaction receipt for a given transaction hash using eth_getTransactionReceipt, returning status, gas used, logs, and block info.

Resolves a .eth ENS name to its Ethereum address, or an Ethereum address to its primary .eth ENS name, via live eth_call on multiple networks

Retrieves the full receipt for a blockchain transaction by hash, including status, gas usage, block info, and execution metadata across multiple networks.

Retrieves full details for a specific blockchain transaction by its hash, including receipt, status, gas usage, and block info.

Lists all ERC721 NFT token IDs owned by a wallet address within a specific collection using tokenOfOwnerByIndex via eth_call

Fetch an Ethereum block header and transaction hashes for a given block number, tag, or hex value via eth_getBlockByNumber

Fetches an Ethereum block header and its transaction hashes by block number, tag, or hex value via eth_getBlockByNumber

Resolves an ENS name (e.g. vitalik.eth) to its Ethereum address and on-chain metadata across multiple networks

Fetches on-chain smart contract metadata and details for a given contract address on supported EVM networks.

Detects upgradeable proxy patterns (EIP-1967, UUPS, Transparent) for a given Ethereum address and returns the implementation contract address behind the proxy

Returns the next transaction nonce (eth_getTransactionCount) for any Ethereum-compatible wallet address at a given block

Checks whether an Ethereum address is a smart contract by retrieving its deployed bytecode via eth_getCode on multiple EVM networks

Estimates the gas a transaction will consume on Ethereum via eth_estimateGas before it is signed or broadcast

Queries Ethereum-compatible contract event logs using eth_getLogs, filtered by contract address, event topic, and block range across multiple networks

Returns the pending Ethereum block containing mempool transactions not yet mined, using eth_getBlockByNumber('pending'), across multiple EVM-compatible networks

Returns the EIP-155 chain ID for a specified Ethereum-compatible network via eth_chainId

Returns the current ERC20 token allowance — how many tokens a spender is approved to transfer from an owner's wallet — via live eth_call on supported networks.

Fetches the current on-chain transaction nonce for a given Ethereum-compatible wallet address at a specified block.

Simulates a read-only Ethereum smart contract call via eth_call without sending a transaction to the chain

Returns Ethereum network metadata — chain ID, block height, and gas price — in a single batched RPC call for a given network.

Fetches an Ethereum block header and its transaction hashes by block number, tag, or hex string using eth_getBlockByNumber

Bidirectionally resolves ENS names to Ethereum addresses and Ethereum addresses to their primary ENS names using live eth_call on supported networks

Fetches full Ethereum transaction details (from, to, value, calldata, block) for a given transaction hash using eth_getTransactionByHash

Resolves an Ethereum address to its ENS primary name, or an ENS name to its address, along with chain-related metadata.

Fetches the on-chain transaction receipt for a given blockchain transaction hash, returning status, gas usage, block details, and sender/receiver addresses.

Fetches on-chain transaction details and receipt data for a given transaction hash on Ethereum mainnet, returning decoded metadata, block info, and execution receipt fields.
