Free EVM tools
Read any contract, inspect any token, scan any wallet — in your browser, without writing a line of code. Each tool is one SEL expression on the evmquery API.
ERC-1155 Inspector
Inspect any ERC-1155 contract: uri(id), supply, balance, ERC-165 — without ABIs or {id} substitution headaches.
ERC-20 Token Inspector
One look at any ERC-20: name, symbol, decimals, and total supply formatted with the right precision. Typed reads, no ABI files.
Aave Health Factor Checker
Read any wallet's Aave health factor across chains in one expression. Proxy-aware, struct-decoded.
Why we built these
Most onchain tools either lock you into a wallet flow, hide the contract calls behind a marketplace, or stop at the raw RPC response. The free tools on this page do the opposite: each one is the simplest possible demo of one SEL expression, with the query shown next to the result so you can paste it into your own code.
If a tool helps, the next step is the same in every case. Grab a free API key , drop the same expression into your script, agent, or n8n workflow, and read the chain from anywhere with one HTTP call. The free tier covers 2,000 reads per month, and Multicall3 batching makes that go a long way.
