# Ethereum

You can customise verification conditions based on users' ownership of <mark style="color:purple;">`Ethereum`</mark>tokens. This section serves as a guide to help you to setup those configs.&#x20;

### Select type of token

To get started, select <mark style="color:purple;">`Ethereum`</mark> Assets in WalliD dashboard. You'll have to choose from <mark style="color:purple;">`Fungible tokens`</mark> (ERC-20 and native tokens) or <mark style="color:purple;">`NFTs`</mark> (ERC-721 and 1155). You can mix token types and bundle as many tokens as you wish in the same config.

### Fungible token configs

**Token type** - Choose from <mark style="color:purple;">`ERC-20`</mark> or <mark style="color:purple;">`native`</mark> (ETH token).

**Smart contract address** - Paste the <mark style="color:purple;">`smart contract address`</mark> of the token you wish to add to your verification config. If you've selected native, this field will automatically be filled.

**Minimum amount held** - Define the value for the <mark style="color:purple;">`Minimum amount`</mark>t of tokens held by the user for a successful verification.

**Max amount held** - Define the value for the <mark style="color:purple;">`Max amount`</mark> of tokens held by the user for a successful verification.

A**dd another level** - Add more values to the <mark style="color:purple;">`Max amount`</mark> held and <mark style="color:purple;">`Minimum amount`</mark> held to create different levels of verification based on token ownership.

### NFT configs

**Token type** - Choose from <mark style="color:purple;">`ERC-721`</mark> or <mark style="color:purple;">`ERC-155`</mark>.&#x20;

**Smart contract address** - Paste the smart contract address of the token you wish to add to your verification config.

**Minimum amount held** - Define the value for the <mark style="color:purple;">`Minimum amount`</mark> of tokens held by the user for a successful verification. The verification will ignore any specificities of the tokens and their IDs.

**Max amount held** - Define the value for the <mark style="color:purple;">`Max amount`</mark> of tokens held by the user for a successful verification. The verification will ignore any specificities of the tokens and their IDs.

**Unique ID -** Provide the <mark style="color:purple;">`#ID`</mark> of a specific NFT you wish to verify ownership of. If the NFT is hosted on an <mark style="color:purple;">`ERC-1155`</mark> contract, you can also define a <mark style="color:purple;">`Minimum amount`</mark> and <mark style="color:purple;">`Max amount`</mark> of tokens held by the user for a successful verification.

**Add another level** - Add more values to the <mark style="color:purple;">`Max amount`</mark> held and<mark style="color:purple;">`Minimum amount`</mark> held to create different levels of verification based on token ownership.
