# Instruments and aliases

> Understand Meridian canonical products, exchange mappings, and the current M2 futures universe.

Meridian normalizes venue-specific symbols to canonical products. Query responses always identify the canonical `exchange` and `product`; venue aliases are accepted where the instrument registry has a verified mapping.

## Futures venues

| Canonical exchange | Common accepted aliases | Contract family   |
| ------------------ | ----------------------- | ----------------- |
| `binance-futures`  | `binance`               | USDT perpetuals   |
| `bybit`            | `bybit`                 | Linear perpetuals |
| `okx`              | `okx`                   | USDT swaps        |
| `hyperliquid`      | `hyperliquid`           | Perpetuals        |

Examples such as `BTC`, `BTCUSDT`, `BTC-USDT-SWAP`, and `BTC-PERP` can resolve to canonical BTC futures identities where the requested venue supports the contract.

## Spot venues

Spot data currently covers verified products across Binance, Bybit, OKX, and Coinbase. Coinbase USD symbols such as `BTCUSD` are normalized alongside USDT products on the other venues.

## Current futures universe

The current expansion contract contains 51 canonical futures products:
