Callisto assets list library

This package contains multi chain asset lists with Tokens and NFTs

How to use

1. Install the package npm i @callisto-enterprice/assetslist

2. Get Token or NFT asset list for each supported chain, e.g.

import {
  CallistAssetChainId,
  CallistoNftList,
  CallistoTokenList,
  getCallistoNFT,
  getCallistoToken,
} from '@callisto-enterprise/assetslist'

const mainnetTokens = CallistoTokenList[CallistAssetChainId.Mainnet] // or just 820
const mainnetNFTs = CallistoNftList[CallistAssetChainId.Mainnet]

// Or find any specific asset by address
const nft = getCallistoNFT('0x...', CallistAssetChainId.Mainnet)
const token = getCallistoToken('0x...', CallistAssetChainId.Mainnet)
import {
  CallistAssetChainId,
  CallistoNftList,
  CallistoTokenList,
  getCallistoNFT,
  getCallistoToken,
} from '@callisto-enterprise/assetslist'

const mainnetTokens = CallistoTokenList[CallistAssetChainId.Mainnet] // or just 820
const mainnetNFTs = CallistoNftList[CallistAssetChainId.Mainnet]

// Or find any specific asset by address
const nft = getCallistoNFT('0x...', CallistAssetChainId.Mainnet)
const token = getCallistoToken('0x...', CallistAssetChainId.Mainnet)

Here is the structure of the Asset interface

export interface CallistoAsset {
  address: string
  category: AssetType // NATIVE, ERC20, ERC223, ERC721, ERC1155, CALLISTONFT
  name: string
  symbol: string
  image: string // for the NFT it could be a fallback image
  audit: {
    isAudited: boolean
    reportUrl?: string
    riskLevel?: string
  }
  decimals: number
  platforms: string[]
  projectUrl: string
}
export interface CallistoAsset {
  address: string
  category: AssetType // NATIVE, ERC20, ERC223, ERC721, ERC1155, CALLISTONFT
  name: string
  symbol: string
  image: string // for the NFT it could be a fallback image
  audit: {
    isAudited: boolean
    reportUrl?: string
    riskLevel?: string
  }
  decimals: number
  platforms: string[]
  projectUrl: string
}

Here is the structure of the AssetNFT interface which extends the Asset interface

export interface CallistoAssetNFT extends CallistoAsset {
  collectionName: string
  placeholderName?: string // usually when it is undefined, it is filled by Asset.name
  placeholderId?: string // it can be filled by the contract tokenId() during the parsing
  placeholderTitle?: string // it can be filled by collectionName during the parsing
  placeholderDescription?: string
  placeholderMedia?: string // it cann be filled by specific standard, for example for ERC721 is used tokenURI()
}
export interface CallistoAssetNFT extends CallistoAsset {
  collectionName: string
  placeholderName?: string // usually when it is undefined, it is filled by Asset.name
  placeholderId?: string // it can be filled by the contract tokenId() during the parsing
  placeholderTitle?: string // it can be filled by collectionName during the parsing
  placeholderDescription?: string
  placeholderMedia?: string // it cann be filled by specific standard, for example for ERC721 is used tokenURI()
}

The placeholder fields are used for the UI, especially for CallistoNFT standard, since we want to show different data accross different collections We decided to choose placeholder approach when the same UI placeholder can point to different NFT metadata as you can see at the image below
