Use local images

If you want to improve performances, you may want to use local images, to do so, simply set the following variables in the configuration:

  use_local_images: true,
  local_image_path: './token_images/tokens',

The local_image_path will be suffixed with the token number, ie, here, it will seek for an image named ./token_images/tokens0034.png if the token #34 is sold.

Plugins / extendability

You can create custom interactions by implementing custom extensions by extending the BaseService base class, an example is provided in the extensions/phunks.bid.extension.service.ts. Once implemented, you can activate an extension by importing it in the AppModule service providers, ie:

@Module({
  imports: [HttpModule],
  controllers: [],
  providers: [
    Erc721SalesService, 
    PhunksBidService,
  ],
})

Discord support

Just add a DISCORD_TOKEN in your .env file, also add saleMessageDiscord and discord_channel keys. The later must contain the identifier of the channel you want the bot to post the sale events in. You'll also need the local_image_path containing tokens images.

You can add a link to the tweet that's been generated in the discord message using <tweetLink> in your saleMessageDiscord template.

To setup the bot, lead to https://discord.com/developers and create an application and a bot, then invite the bot you just created using the following link: https://discord.com/api/oauth2/authorize?client_id=[yourDiscordAppclientId]&permissions=268512336&scope=bot%20applications.commands, then ensure that the invited bot is allowed to access the channel ID you want your bot to post into.

Statistics module

You can enable the optional statistics module in the AppModule definition file app.module.ts. When enabled, it will index the blockchain for the specified contract in the configuration, starting at block statistic_initial_block. Once indexed, the discord bot will reply to the following commands:

• /owned <wallet> will display a list of the owned tokens by a wallet.
• /wallet <wallet> will display some statistics for a given wallet (owned token, days since the first owned tokens, total volume of transaction)
• /volume <window> will display a volume of transactions per marketplace.
• /graph <wallet> will display a graph showing the average price and the volume of transaction over time, the wallet parameter is optional and will filter out the data on the specified wallet.
• /traders <window> <wallet> will display the top 20 traders for the tracked collection over the specified time window, the wallet parameter is optional and will force the given wallet to be displayed along it's rank if it has traded at least one NFT over the specified period.
• /index <block> <tx> force indexation by the statistic module of the given transaction within the given block.
• /transaction <tx> displays indexed informations about a given transaction, usefull for debugging purpose.

The message templates for each command can be customized through the configuration file.

DAO module

You can enable the optional DAO module in the AppModule definition file app.module.ts, it requires the statistics module to be enabled as well. When enabled, it will make available commands to let users bind their web3 wallets to their discord account through the /bind command ; creating a bridge between web3 ownership tracability and discord community management features.

This binding enable a lot of possibilities:

• The bounded wallets can be used to grant specific roles on the configured discord server, check out the sample configuration file to see how to grant roles for users owning a token of the collection, for the ones who originally minted the collection, or the ones owning tokens with a specific trait.

• The DAO module includes a voting mechanism that let the discord administrators to create polls for the communities, these votes are anonymous and administrable through the /createpoll <description> <duration> <roles>, /pollresults <id>, and /listpolls commands.

CLI mode

You can use this app as a standalone cli using the following command line along with the block and tx parameter. The optional contract parameter can be used to override the contract from the configuration. ie:

npm run cli -- --action=tweet --contract=0xA6Cd272874Ee7C872Eb66801Eff62784C0b13285 --block=17886451 --tx=0x6018d9290709e7d34c820b23820aaacf960af9c4f073b661136d49fc0994d6c9

Will replay the given transaction and trigger the tweets detected within it. And:

npm run cli -- --action=index --contract=0xf07468eAd8cf26c752C676E43C814FEe9c8CF402 --block=14763639 --tx=0x1e0667e75e4aba0f5cb303d79969a7514ed1248b91889d2bb553863992ddff7e
