Usage

@solana/spl-token-registry

Solana Token Registry is a package that allows application to query for list of tokens. The JSON schema for the tokens includes: chainId, address, name, decimals, symbol, logoURI (optional), tags (optional), and custom extensions metadata.

Installation

npm install @solana/spl-token-registry

yarn add @solana/spl-token-registry

Examples

Query available tokens

new TokenListProvider().resolve().then((tokens) => {
  const tokenList = tokens.filterByClusterSlug('mainnet-beta').getList();
  console.log(tokenList);
});

Render icon for token in React

import React, { useEffect, useState } from 'react';
import { TokenListProvider, TokenInfo } from '@solana/spl-token-registry';


export const Icon = (props: { mint: string }) => {
  const [tokenMap, setTokenMap] = useState<Map<string, TokenInfo>>(new Map());

  useEffect(() => {
    new TokenListProvider().resolve().then(tokens => {
      const tokenList = tokens.filterByChainId(ENV.MainnetBeta).getList();

      setTokenMap(tokenList.reduce((map, item) => {
        map.set(item.address, item);
        return map;
      },new Map()));
    });
  }, [setTokenMap]);

  const token = tokenMap.get(props.mint);
  if (!token || !token.logoURI) return null;

  return (<img src={token.logoURI} />);

Adding new token

To add a new token, add another json block to the large tokens list in src/tokens/solana.tokenlist.json and submit a PR.

Tips:

• logoURI
  • should point to a png, jpg, or svg.
  • the logo can be hosted in this repo in assets/mainnet/TOKEN_ADDRESS/FILE
    • in that case, the image should be added to this repo and logoURI should point to https://raw.githubusercontent.com/solana-labs/token-list/main/assets/mainnet/TOKEN_ADDRESS/FILE)
  • if your logo is hosted in any other repo or any other location, no need to add it here
• tags
  • please don't go crazy here, note that the valid tags are in the toplevel tags section and any other tags will likely have no effect
• `extensions:
  • the extensions block can contain links to your twitter, discord, etc. A list of allowed extensions is here.
  • serumV3Usdc and serumV3Usdt are the addresses of serum markets for your token (either paired with USDC or USDT)
  • coingeckoId is the string that appears as 'API id' on the corresponding coingecko page
• it's recommended to not add your token as the final element to the list (second-to-last is best). This is because adding the token as the final element will create merge conflicts that are more difficult for maintainers to manually resolve.
• please squash commits into a single commit for cleanliness

Changes will be automerged. If automerge fails, you can click the 'Details' link for more information.

Please follow the Uniswap Token List specification found here: https://github.com/Uniswap/token-lists

Modifying existing token

Modifications currently must be manually reviewed. For any modifications, please submit a PR, then raise an issue with a link to your PR (and leave the PR open) in order to request manual review.

• please check the 'Files changed' tab on your PR to ensure that your change is as expected
• please link the commit or PR where the token was originally added. If the token was added by someone else, they will be asked to confirm that this change is authorized
• please squash commits into a single commit for cleanliness

Common issues

Automerge failure: found removed line

Any modifications must be manually merged; please submit an issue with a link to your PR (and leave the PR open).

Failed to normalize: failed to parse JSON: json: unknown field

e.g. failed to normalize: failed to parse JSON: json: unknown field "coingeckoId"

If this error is encountered while modifying an existing entry, note that this error is misleading; it is the automerger's way of saying that adding coingeckoId to an existing entry is not allowed.

Any modifications must be manually merged; please submit an issue with a link to your PR (and leave the PR open).

Duplicate token

"duplicate token: token address ... is already used"

This occurs because the diff in your PR is re-adding a completely new block for a token that was already previously added. (You can verify this by looking at the 'Files changed' tab of your PR.)

This usually happens because your PR is intended to update an existing token, but it still includes the commits that added the original token (which were previously merged). You can verify this by checking the 'commits' tab of the PR. If you see the original commit in there, that's bad! The PR should be relative to the current HEAD of main, i.e. your checkout should be rebased

To fix this, you can either:

1. checkout the latest HEAD of main and then re-apply your change (simpler for git newbies but incurring a bit of duplicate work), or
2. rebase your local checkout back to origin/main before opening a PR.

For option (2), you can do this with:

git remote add pub-origin [email protected]:solana-labs/token-list.git
git fetch pub-origin main 
git rebase pub-origin/main
git push origin main -f

More generally, for modifications to existing tokens, be sure to checkout the HEAD of the main branch, locate the existing block in solana.tokenlist.json, and modify the appropriate fields.

Always check the 'Files changed' tab on your PR to see the impact of your change.

Scanner/wallet hasn't updated yet

Solscan, solana explorer, and wallets all pull from this repo at different cadences. Some update every few days.

If your change has landed in the HEAD of main branch, it was successful, but it might take a few days for downstream users to reflect that change.

Please especially do not raise issues saying 'solscan has updated but phantom has not', that definitely means your change is in this repo!

error validating schema: chainId: conflicting values 103 and 0

This automerge error arises if you touched a line outside of your token block. Some text editors introduce a diff to the final line of the file. You can see this by looking at the "Files changed" tab of your PR.

If using vim, you can probably address this by adding

set nofixendofline

to ~/.vimrc

If you don't address this yourself, the PR will need to be manually merged; please submit an issue and link your PR.

Warning about the last element in the list

Please do not add your token as the final element to the list (second-to-last is best). This is because when the token is the final element, the closing brace won't be followed by a comma, which creates a specialcase which will create a merge conflict if the commit doesn't get automerged. This prevents the maintainers from manually merging your change in the event that it needs to be automerged.

If the maintainers link you to this comment, it means you need to move your block in order for them to merge it.

Addressing this more seamlessly is an open item; bear with us for now.
