# Overview

> An introduction to Prism's EVM assets data platform.

## Data Ingestion and Processing

Prism's ingestion layer captures **every ERC-20 token movement** on each supported chain by decoding `Transfer` events from transaction receipts.

This approach provides a **complete, receipt-accurate view of token flow**, ensuring every transfer can be replayed and verified against the chain.

Through this unified pipeline, Prism delivers:

* **Full token visibility:** every ERC-20 movement, with no protocol blind spots.
* **Mints and burns as first-class events:** transfers from and to the zero address are classified explicitly rather than being lost in generic transfer traffic.
* **Source-of-truth accuracy:** all data is derived directly from on-chain event logs, not inferred from external indexers.

## Coverage

Prism indexes the ERC-20 token standard, capturing transfers along with the mints and burns that change total supply.

| Standard | Alias    | Description                             |
| -------- | -------- | --------------------------------------- |
| ERC-20   | `erc_20` | Standard fungible tokens on EVM chains. |

<Note>
  There is no balances dataset on EVM. ERC-20 balances live in contract storage
  rather than in transaction metadata, so they cannot be derived from receipts
  the way Solana's pre- and post-transaction token balances can. Use
  [transfers](/documentation/evm/assets/datasets/transfer) to reconstruct flow.
