# Tokens

> ERC-20 symbols and identifiers for transfers and managed wallets — validated combinations per chain.

## Overview

Token identifiers in Prudra are **string symbols** such as `USDC`, `USDT`, `USDC_E`, `DAI`, and native `ETH` where applicable. The server resolves each `(chain, token)` pair to a contract address and decimals. If a pair is not configured, the API returns a validation error before signing.

## Common tokens

| Symbol   | Typical usage                                           |
| -------- | ------------------------------------------------------- |
| `USDC`   | USD Coin on EVM L1/L2s.                                 |
| `USDT`   | Tether.                                                 |
| `USDC_E` | Bridged / tempo-specific USDC variant (see Tempo docs). |
| `DAI`    | MakerDAO stablecoin.                                    |
| `ETH`    | Native gas token for EVM chains.                        |

Exact availability depends on the chain. Always rely on server validation rather than assuming a symbol works everywhere.

## SDK

`@prudra/core` exports `Token` and type `TokenType`:

```typescript theme={null}
import { Token } from '@prudra/core';

await transferManagedTokens({
  fromToken: Token.USDC,
  toToken: Token.USDT,
  // ...
});
```

## API validation

Transfer and withdrawal bodies include `fromToken`, `toToken`, or `token` fields. Prudra checks:

1. Chain is supported.
2. Token contract exists for that chain.
3. Amount parses as a non-negative decimal string compatible with token decimals.
