Onchain & crypto

ENS resolution on Ethereum: name to address (vitalik.eth -> 0x...) or address to primary name, with round-trip verification of reverse records.

ENS profile: resolved address plus public text records (avatar, description, url, twitter, github, telegram, discord, email).

USD price of one or more Solana tokens by mint address (up to 20 at once): price, 24h change and on-chain liquidity, derived from real liquidity via Jupiter, Solana's leading aggregator. Live open data.

Solana wallet balances: SOL plus every SPL and Token-2022 token held (mint, amount, decimals), with USD value for USDC/USDT.

First recorded price of one or more tokens and its date (when it started trading), with current price and the multiple and % change since then. Symbols (BTC, ETH, SOL...) or chain:contract ids. DefiLlama data.

Official tokenized versions of a US stock or ETF on Solana (xStocks by Backed and Ondo Global Markets): verified mint addresses, on-chain supply and issuer authority check. Accepts NVDA, NVDAx or NVDAon.

Who an EVM address is before you interact: public labels (exchange, protocol, bridge, fund...), ENS name, whether it is a contract and which, verification, scam flag or poor reputation, EIP-7702 delegation, balance and activity.

Classify up to 50 EVM addresses at once: regular wallet (EOA), EIP-7702 delegated wallet or contract, with code size. Filter airdrop lists, spot contracts or bots. 12 chains.

Resolve a Basename (name.base.eth on Base) to its address, or an address to its verified primary Basename (reverse record checked forward).

Bitcoin network now: block height and latest blocks, recommended fees in sat/vB to confirm in 1, 3, 6, 24 or 144 blocks, mempool size, difficulty, estimated hashrate and next difficulty adjustment (date and expected change), plus BTC price.

Block number closest to a date and time on EVM chains (ethereum, base, arbitrum, optimism, polygon, bsc, avax...), with the block's own timestamp. For historical state queries and event filters.

Live status of Bitcoin, Solana and 12 EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain): latest block, seconds since last block, gas and whether each network is ok, slow or halted.

Translates a 4-byte function selector (e.g. 0xa9059cbb) or a 32-byte event topic into its human-readable signature (e.g. transfer(address,uint256)). Essential for an agent reading or verifying transactions. Live from 4byte.directory.

Expiry of a .eth (ENS) or .base.eth (Basename) name: expiration date, days left, grace period end, registrant and whether it is free to register.

ETH burned by the EIP-1559 base fee over the last N blocks versus estimated validator issuance: burned total, issuance, net supply change (deflationary or not) and its daily and yearly extrapolation.

Block header by number, hex or tag (latest, safe, finalized): hash, parent, time, producer, gas used and limit, base fee, transaction count and optionally the tx hashes. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Network status: chainId, block height and age, gas price, base fee, suggested priority fee, node client version and sync status. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Current block height (chain tip) with block time and age in seconds. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Run a read-only eth_call with pre-encoded hex calldata and get the raw result split into 32-byte words, or the revert reason. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Live balance of a wallet: native coin plus up to 20 ERC-20 tokens you choose (USDC/USDT by default) in one call. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Balance of one ERC-20 token in a wallet with symbol and decimals. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Fee history of the last N blocks on an EVM chain (eth_feeHistory): base fee per block, gas usage and priority tips at the 10th, 50th and 90th percentiles, with a tip recommendation to get included fast. 12 chains.

Current mid price of every Hyperliquid asset, or the ones you ask for (BTC, ETH, SOL, HYPE...), in one fast and cheap call.

Latest block on an EVM chain: number, hash, time, age in seconds, transaction count, gas used % and base fee.

Morpho lending vaults run by curators: name, deposited asset, chain, net APY, deposits in USD, fee and curator; filter by asset (USDC, WETH...) and chain, sort by deposits or APY.

Token ids of an ERC-721 collection held by a wallet (tokenOfOwnerByIndex on enumerable collections) and the total count. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Detect whether a contract is an upgradeable proxy (EIP-1967 transparent/UUPS, beacon, ZeppelinOS, EIP-1167 minimal) and return implementation, admin and beacon. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.

Resolve a Solana Name Service .sol domain to its owner wallet, read directly on-chain (NFT-tokenized domains resolve to the NFT holder).

Solana account inspector: whether it exists, type (wallet, token account, mint, program, program data), SOL balance, owner program and data size.

Primary (favourite) .sol domain of a Solana wallet, read on-chain and checked that the wallet still owns it.
