As of June 20th, this repository will be archived and will receive no more updates. The repository will be set to read-only and the npm package will still exist at `@miraland/spl-token-registry`.

## Adding a New Token

You can use one of two tools at the time of writing:

1. [Strata Protocol Token Launchpad](https://app.strataprotocol.com/launchpad/manual/new)
2. [Token Creator Demo](https://token-creator-lac.vercel.app/)

All new token metadata will be added using Metaplex Fungible Token Metadata. The steps to add new Fungible Token Metadata are as follows:

1. Use `CreateMetadataV2` instruction from Metaplex token metadata to create new metadata for token.
2. Make sure you use the correct format for the token metadata.
3. You must have mint authority in order to create or update the metadata

The token metadata for Metaplex Metadata Schema is in the following format:

```json
{
  "name": "TOKEN_NAME", 
  "symbol": "TOKEN_SYMBOL",
  "uri": "TOKEN_URI",
  "sellerFeeBasisPoints": 0,
  "creators": null,
  "collection": null,
  "uses": null
}
```

The `TOKEN_URI` must point to a file with the following format:

```json
{
  "name": "TOKEN_NAME",
  "symbol": "TOKEN_SYMBOL",
  "description": "TOKEN_DESC",
  "image": "TOKEN_IMAGE_URL"
}
```

Where `TOKEN_IMAGE_URL` is the image url.

An example of the `TOKEN_URI`: https://token-creator-lac.vercel.app/token_metadata.json

Which resolves to:

```json
{
  "name": "A test token",
  "symbol": "TEST",
  "description": "Fully for testing purposes only",
  "image": "https://token-creator-lac.vercel.app/token_image.png"
}
```

## Updating Token Metadata

To update token metadata you must use `createUpdateMetadataAccountV2Instruction` in `@metaplex-foundation/js` in order to update an existing token's metadata.

While updating, you provide the same details as when creating.

## Tools for Adding/Updating/Migrating

Update/migrate token metadata using [Strata Protocol update token tool](https://app.strataprotocol.com/edit-metadata).

A tutorial for adding/updating metadata can be found at the [Token-Creator demo](https://github.com/jacobcreech/Token-Creator).


## Reading Legacy Token-list

`@miraland/spl-token-registry`

[![npm](https://img.shields.io/npm/v/@miraland/spl-token-registry)](https://unpkg.com/@miraland/spl-token-registry@latest/) [![GitHub license](https://img.shields.io/badge/license-APACHE-blue.svg)](https://github.com/miralandlabs/token-list/blob/b3fa86b3fdd9c817139e38641d46c5a892542a52/LICENSE)

Miraland 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

```bash
npm install @miraland/spl-token-registry
```

```bash
yarn add @miraland/spl-token-registry
```

### Examples

#### Query available tokens

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

#### Render icon for token in React

```typescript jsx
import React, { useEffect, useState } from 'react';
import { TokenListProvider, TokenInfo } from '@miraland/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.Mainnet).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} />);

```

The reader should be aware that U.S. export control and sanctions laws
prohibit U.S. persons (and other persons that are subject to such laws)
from transacting with persons in certain countries and territories or
that are on the SDN list. As a project based primarily on open-source
software, it is possible that such sanctioned persons may nevertheless
bypass prohibitions, obtain the code comprising the Miraland blockchain
protocol (or other project code or applications) and deploy, integrate,
or otherwise use it. Accordingly, there is a risk to individuals that
other persons using the Miraland blockchain protocol may be sanctioned
persons and that transactions with such persons would be a violation of
U.S. export controls and sanctions law. This risk applies to
individuals, organizations, and other ecosystem participants that
deploy, integrate, or use the Miraland blockchain protocol code directly
(e.g., as a node operator), and individuals that transact on the Miraland
blockchain through light clients, third party interfaces, and/or wallet
software.
