In the previous article, you have learned how to add your token to the list of assets on Trezor. But we’re sure, you want to make your ERC20 token even more reliable for buyers and holders. Moreover, you want to make it at no cost. That’s not a problem – read the guide below. You’ll learn how to make your ERC-20 token a permanent default token on MEW (MyEtherWallet).

Also, make your cryptocurrency more attractive for free:

What is a Permanent default list on MEW?

As you know, Myetherwallet (MEW) supports all ERC20 tokens. Some of these tokens MEW includes in its permanent default list, which means tokens’ balances show up automatically on the side of the interface.
But, there are many thousands of tokens that are not included. So, users have to add them as custom tokens manually. Custom tokens are only saved locally. Therefore if a user clears the cache, tokens disappear and need to be re-added.
However, if you add your token as a default asset via Github, then MEW puts it in the permanent default list.

Moreover, after adding your token to the permanent list, the MEW wallet app starts uploading a token logo from its database.

How to add a token to the Permanent default list on MEW?

Follow the six simple steps to add your ERC20 token to the Permanent default list on the MEW wallet. But before you start, check your token – might be it’s already in the default token list on MEW.

Also, important to note that there is no option to add Binance Smart Chain (BEP20) tokens to the MEW’s list at that moment.

Step 1. Sign in Github

Log in to Github and go to that page.

Step 2. Create a new file

Click on the ‘Add file’ and then, on the ‘Create new file’ button as shown on the screen below.

Step 3. Enter a file name

The name of your file must be in the format <YourTokenAddress>.json
For example, 0x3d371413dd5489f3a04c07c0c2ce369c20986ceb.json
You can get your token’s smart contract address from Etherscan.

Step 4. Enter the code

Write and enter the code into your file like in the example below.
Of course, after copy-pasting the code below you should edit it. Edit by entering the specifications of your token. Replace YOUC with your token symbol, enter your token smart contract address, decimals, etc.

What is MyEtherWallet (MEW)?

MyEtherWallet (MEW) is more than just a cryptocurrency wallet. It’s an open-source, client-side interface that allows users to interact directly with the Ethereum blockchain. Users don’t have to join any centralized exchange.

MEW users can perform the following actions:

  • Create a personal Ethereum wallet with many addresses.
  • Receive and send not only ETH but also any other Ethereum based tokens.
  • Use different versions of the MEW wallet. These versions consist of web, mobile app, browser extension MEW CX, MetaMask Chrome extension, and partnering hardware wallets like Ledger and Trezor.
  • Swap most popular cryptocurrencies such as ERC20 tokens, ETH, ETC, BTC, etc.
  • Explore MyEtherWallet’s DApp store. It’s a place where users can open a vault with MakerDAO, or register and manage ENS domains.
  • Send funds in offline mode.
  • Deploy and interact with smart contracts.

What are the advantages of being on MEW as a permanent default token?

It’s hard to overestimate the benefits that a crypto project gets after its cryptocurrency appears on the MEW as a default permanent token.

First, your project’s token immediately stands out from thousands of no-name & no-logo cryptocurrencies. Second, any token-holder can see the tokens’ USD price, balance, and logo permanently and automatically on their MEW interface.

Therefore, your token becomes more attractive and reliable for its current and future holders.

How to check Permanent Default Tokens on MEW?

To easily check any token availability on the MEW’s permanent default token list, download the MEW wallet to your smartphone. Then, open the ‘Market’ section and enter a token name into the search field.

For example, on the screenshots below you can see that the YOUcash token is not yet added to the permanent default token list on MEW. On the other hand, the TOKPIE token is already there.
