# Tokens & Liquidity Streams Overview

> Subscribe to real-time updates for tokens and liquidity pools metadata.

## Overview

The Tokens & Liquidity streams provide real-time notifications for new ERC-20 token registrations and AMM pool deployments.

## Stream Matrix

| Stream                                                    | Summary                                             | Dataset ID |
| :-------------------------------------------------------- | :-------------------------------------------------- | :--------- |
| [ERC-20 Tokens](/wss-reference/evm/entities/tokens-erc20) | Real-time notifications for new token registrations | `0201`     |
| [AMM Pools](/wss-reference/evm/entities/pools)            | Notifications for new pool deployments across DEXs  | `0203`     |
| [Fee Terms](/wss-reference/evm/entities/fee-terms)        | Real-time updates to pool fee configurations        | `0204`     |

## Parameter Conventions

<ParamField body="chain_id" type="number" required>
  Chain identifier for the target EVM network. See [Chain enumeration](/api-reference/enumerations/chain) for supported values.
</ParamField>

### Filters

* **ERC-20 Tokens**: `address` (filter to a specific token).
* **AMM Pools**: `exchange_ids`, `pool_type_ids`.
* **Fee Terms**: `pool_uids`, `exchange_ids`.

## Usage Guidance

* **New Asset Discovery** — Use these streams to discover new tokens and pools as soon as they are deployed.
* **Join with Reserves** — Use the `pool_uid` from a new pool event to subscribe to its [Reserves](/wss-reference/evm/reserves/reserves) stream.
