# ERC-20 Tokens

> Token support on Privacy Cash EVM

## Current Token Support

Privacy Cash EVM supports native ETH and selected ERC-20 pools per network.

| Network  | Chain ID | Supported tokens |
| -------- | -------- | ---------------- |
| Base     | `8453`   | ETH, USDC        |
| Ethereum | `1`      | ETH, USDT        |

***

## Working with Amounts

The SDK uses decimal token amounts throughout. Use ETH decimals for the native asset and token decimals for ERC-20 balances.

```typescript theme={null}
import { BASE_NETWORK, ETH_NETWORK, deposit, withdraw, getBalance } from 'privacycash-evm'

// Deposit 0.05 ETH on Ethereum
await deposit({
  depositAmountInput: 0.05,
  token: 'eth',
  network: ETH_NETWORK,
  keyBasePath,
  signature,
  address,
  txSender,
})

// Withdraw 10 USDC on Base
await withdraw({
  withdrawAmountInput: 10,
  token: 'usdc',
  network: BASE_NETWORK,
  recipient,
  keyBasePath,
  signature,
  address,
})

// Balance is returned as a string
const { balance } = await getBalance({
  token: 'usdt',
  network: ETH_NETWORK,
  signature,
  address,
})
console.log(balance) // "10.000000"
```

### Converting to Wei

If you need to work in base units for UI display or comparison:

```typescript theme={null}
import { ethers } from 'ethers'

const ethWei = ethers.utils.parseEther('0.05')
const usdcUnits = ethers.utils.parseUnits('10', 6)

console.log('ETH in wei:', ethWei.toString())
console.log('USDC in base units:', usdcUnits.toString())
```

<Info>
  Passing an unsupported token/network pair throws an SDK error. Use Base ETH/USDC or Ethereum ETH/USDT.
