Multi-chain toolkit · no wallet connect · free


Paste an address, transaction or website. UseAnyChain tells you which blockchain it belongs to, checks it live, and keeps you from sending to the wrong network.

01

Paste.

An address. A transaction. An ENS name. A website. You don’t need to know the chain - that’s our job.

02

Detect.

Format, checksum and prefix rules narrow it down across EVM chains, Solana, Bitcoin, TRON, Cosmos, TON, Sui and Aptos.

03

Verify.

Live, read-only calls to public nodes show balances, contracts and history on every chain that could match - in parallel.

04

Explain.

For websites, UseAnyChain reads the pages, explorer links and contract addresses to tell you which chains a project really supports, with evidence.

One engine.
Every surface.

Tool

Paste anything

One box for addresses, tx hashes, ENS names and domains. Detected, validated and checked live.

Tool

Domain chain scanner

Point it at any website. It reads pages, explorer links and contracts and reports which chains the project supports - with evidence.

Tool

Wrong-chain guard

About to send? Confirm the address fits the network you picked before it costs you money.

Data

Open chain registry

Address formats, explorers and RPCs for every supported chain, one clean page each.

API

REST API

The exact engine behind this site, free and CORS-open, documented with OpenAPI.

Agents

MCP server

Give any AI agent multi-chain eyes. Plug the endpoint into Claude or any MCP client.

14 chains and growing.

EVM chains share one address format; the rest each have their own. We know the difference so you don’t have to.

Built for builders
and their agents.

Everything the site does is an API call. Free, CORS-enabled, no signup. Add an ai=1 flag to have Claude write a plain-English brief from the parsed facts.

Quiet by design.

Read-only

We never ask for a wallet connection, signature, seed phrase or private key. Ever.

No tracking

No accounts, no ad scripts. Queries are processed to answer you and not sold.

Evidence, not vibes

Every claim shows where it came from: a link, a contract, an on-chain call.

Paste something.
See the chain.
