Crowned token lists

Chain Daddy publishes the tokens it has crowned as token lists in the Uniswap token-list format, the one wallets, DEXs and explorers import. Anyone may use them. No key is needed.

List	URL
Every EVM chain	https://api.chaindaddy.io/api/v2/public/tokenlists/crowned.json
One chain	https://api.chaindaddy.io/api/v2/public/tokenlists/{chainId}/crowned.json, e.g. …/8453/crowned.json for Base

What is in a list

A token is in the lists while all of these hold:

• Its registration (its crown) is active: not released, and not lapsed for a low heartbeat.
• Its coin page is verified, and Chain Daddy has not removed it.
• Its heartbeat score is above zero. A token that can never be bought again scores zero, so it leaves the lists.

When a token stops meeting one of them it leaves the lists within about ten minutes. Solana tokens are not in the lists, because the format names a chain by its EVM chain ID.

A token

{
  "chainId": 8453,
  "address": "0x931FCe21DDea0549db70324f44EE2Db1cb9F7f22",
  "symbol": "FLUXGP",
  "name": "FLUX GP",
  "decimals": 18,
  "logoURI": "https://api.chaindaddy.io/api/v2/og/icon/192/FLUXGP/base",
  "tags": ["crowned"],
  "extensions": {
    "crownId": 8,
    "pageUrl": "https://chaindaddy.io/fluxgp/base"
  }
}

• address is checksummed.
• logoURI is the registration's icon, served by Chain Daddy.
• crownId is the registration's ID on its chain; the public reads take it.
• pageUrl is the coin's page on Chain Daddy.

Versions

Each list has its own version, and it moves the way the format says:

Change	Version
A token leaves	major (2.0.0)
A token joins	minor (1.1.0)
Only a token's details change (its name, its decimals)	patch (1.0.1)

timestamp is when the list last changed, not when you fetched it.

Caching and errors

A list is cached for about five minutes, at the edge and by Chain Daddy, and is the same for every caller. It answers Access-Control-Allow-Origin: *, so a browser can fetch it without credentials.

• 404: a chain with no crowned token (a token list holds at least one token), a chain Chain Daddy does not serve, or a chain ID spelled any other way than its plain number.
• 503: the list could not be built just now. Try again.
