Resolves an ENS name (e.g. alice.eth, *.base.eth) to its Ethereum address by reading live from the ENS resolver on Ethereum mainnet

Simulates an EVM transaction using eth_estimateGas and returns estimated gas units and fee in wei/ETH, or a decoded revert reason if the transaction would fail.

Returns the live ERC-20 token balance (raw and decimal-formatted) held by a wallet address on a specified EVM chain

Resolves an ENS name to its Ethereum address and text records (avatar, URL, email, Twitter, GitHub, etc.) in a single live call from the Ethereum mainnet resolver.

Detects whether a smart contract is an upgradeable proxy and resolves its implementation address by reading EIP-1967, EIP-1822, OpenZeppelin legacy, and EIP-1167 minimal-proxy slots on-chain.

Returns the live on-chain spending allowance an owner has granted to a spender for a given ERC-20 token, including raw amount, decimal-formatted amount with symbol, and an unlimited-approval flag.

Looks up a Bitcoin transaction by its TXID and returns confirmation status, block height and time, fee, fee rate, size, weight, input/output counts, and total output value.

Returns live gas price, EIP-1559 base fee, and suggested max priority fee for a specified EVM chain in both wei and gwei.

Resolves an NFT (contract address + tokenId) on a specified EVM chain into normalized metadata including name, description, image URL, attributes, and token standard (ERC-721 or ERC-1155).

Reads live ERC-20 token metadata (name, symbol, decimals, total supply) directly from a contract on EVM chains, handling both string and legacy bytes32 encodings.

Returns live recommended Bitcoin fee rates (sat/vB) for five confirmation-speed tiers and estimates total fee cost for a transaction of a given virtual size.

Reverse-resolves an Ethereum address to its primary ENS name by reading the reverse record live on Ethereum mainnet

Performs deterministic on-chain risk analysis of an ERC-20 token by inspecting its bytecode and metadata, flagging dangerous capabilities like blacklist/freeze, owner mint, pausability, and upgradeable proxies with severity scores and a verdict.

Returns live on-chain state for an EVM address: native balance (wei + ether), nonce/transaction count, and whether it's a contract or EOA with code size.

Decodes an on-chain transaction hash into plain-language summary including transfer type, decoded method, ERC-20/NFT token movements, gas cost, and status

Returns confirmed balance, total received/sent, transaction count, and unconfirmed/pending mempool data for a given Bitcoin address.

Returns a live snapshot of the Bitcoin mempool including unconfirmed transaction count, pending virtual size, block backlog, total pending fees, fee-rate histogram, and current chain tip height.

Fetches a live Ethereum/EVM transaction receipt by hash, returning status, gas usage, logs, block info, and contract address if created

Fetches live on-chain status and full details of an EVM transaction by its hash, including success/failure, value, gas, and block info

Decodes a 4-byte function selector or full EVM calldata into a human-readable function signature and decoded argument values, using a supplied ABI or public signature registries as fallback.

Fetches raw and auto-decoded event logs for a specific contract address over a bounded block range on EVM chains, with optional topic filtering.

Fetches a live block summary by number, hex, or tag from EVM chains, returning number, hash, parent, timestamp, transaction count, gas used/limit, base fee, and miner.
