# RWT contracts

> On-chain accounts of the Real World Token

**RWT** is a classic SPL token (6 decimals) on Solana mainnet. Its fundamental value, Book NAV,
is tracked on-chain by the earn program through the `EarnConfig` account.

## RWT mint

The SPL token mint for RWT.

## Earn program

The program that accepts assets, tracks the basket's invested capital, and mints RWT against the
mint invariant.

## EarnConfig PDA

The protocol state account (seed `["earn_config"]`). It holds the invested capital used to derive
Book NAV, and is also the RWT mint authority.

<Note>
  Book NAV is not stored as a price. It is derived as invested capital divided by RWT supply, both
  read live from these accounts. See [Real World Token (RWT)](/how-it-works/rwt) for the full
  mechanism.
