LI.FI custom tokens

LI.FI supports any token passed to the API as long as we can validate it and find a USD price for it.

The API exposes a list of tokens that UIs can use as default to give their users tokens to choose from. e.g. our widget uses that list: https://li.quest/v1/tokens

We automatically include tokens in that token list if they are listed in one of the token lists we support:

• lists of assets the bridges support
• official lists of exchanges we support
• our own custom token list (this repository)

And if we can validate the token:

• we can find USD prices via Debank or Zerion APIs
• the token is not a spam/fee-taking token

You can also add scam tokens to /denyTokens/network.json and we will block this token in our system.

How to add your token

To add your token find the file representing the chain your token is in in the tokens folder.

Add your token as the last element in the list (don't forget the , after the previous token):

  },  <== Add the comma
  {
    "address": "0x155f0DD04424939368972f4e1838687d6a831151",
    "chainId": 42161,
    "logoURI": "https://yoursite.com/token.svg", <= permanent link to an image of your token
    "decimals": 18,
    "name": "Nice Name",
    "symbol": "SYMBOL"
  }
]

How to block a token

To add a scam token find the file representing the chain the token is in in the denyTokens folder.

Add the token as the last element in the list (don't forget the , after the previous token):

  },  <== Add the comma
  {
    "address": "0xde3a24028580884448a5397872046a019649b084",
    "chainId": 43114,
    "reason": "Deprecated USDT token on AVA", <= add an optional reason why the token should be blocked
  }
]

Create a PR with the change describing why we should add that token. Link your project, CoinGecko and profiles so we can validate the token.
