# Chains and tokens

One REST API, one set of endpoints, and the same request shape on every network. Pick a chain, a token standard or an asset below to see what it supports and how to call it.

## Blockchains and networks

Each blockchain has its own reference page covering the endpoints available on it.

## Frequently asked questions

### Does the same endpoint work on every chain listed here?

Yes — that is the point of the catalog. The request shape does not change between chains; the network parameter does. What differs is the model underneath: a UTXO chain has unspent outputs where an account-model chain has a single balance and a nonce, and the API handles that difference for you.

### What is the difference between a blockchain and a layer here?

A blockchain is a network with its own consensus — Bitcoin, Ethereum, Tron. A layer or standard is a token interface that lives on one of them, like ERC-20 on Ethereum or TRC-20 on Tron. A token is a specific asset issued under one of those standards.

### What if the chain I need is not listed?

Then we do not serve it, and the catalog only lists what we do. Tell us what you need through [contact](/contacts) — coverage is driven by what customers actually ask for.
